This project implenments the OSPF using Dijkstra algorithm (Open Shortest Path First) network protocol in python. Link-State Routing protocol is a main class of routing protocols. It is performed by every switching node/router in the network. The basic concept of link-state routing is that every node constructs a map of the connectivity to the network, in the form of a Graph, showing which nodes are connected to which other nodes. Each node then independently calculates the next best logical path from it to every possible destination in the network. The collection of best paths will then form the node's routing table. OSPF: ----- Open Shortest Path First (OSPF) is a link-state routing protocol for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). OSPF is perhaps the most widely used interior gateway protocol (IGP) in large enterprise networks. IS-IS, another link-state dynamic routing protocol, is more common in large service provider networks. The most widely used exterior gateway protocol is the Border Gateway Protocol (BGP), the principal routing protocol between autonomous systems on the Internet. * Advantages of link state routing (as opposed to distance vector routing) include that link state routing converges rather quickly and * is not subject to the count-to-infinity problem; hence, no measures to combat this problem need to be taken. As the full network topology * is known to every node, rather advanced routing techniques can be implemented. * Disadvantages include that the link state information needs to be flooded through the network, causing higher overhead than link state protocols. * The memory and computational requirements are also higher. OSPF is an interior gateway protocol that routes Internet Protocol (IP) packets solely within a single routing domain (autonomous system). It gathers link state information from available routers and constructs a topology map of the network. The topology determines the routing table presented to the Internet Layer which makes routing decisions based solely on the destination IP address found in IP packets. OSPF was designed to support variable-length subnet masking (VLSM) or Classless Inter-Domain Routing (CIDR) addressing models.

What is C++? C++ is a general-purpose, object-oriented programming language. It was created by Bjarne Stroustrup at Bell Labs circa 1980. C++ is very similar to C (invented by Dennis Ritchie in the early 1970s). C++ is so compatible with C that it will probably compile over 99% of C programs without changing a line of source code. Though C++ is a lot of well-structured and safer language than C as it OOPs based. Some computer languages are written for a specific purpose. Like, Java was initially devised to control toasters and some other electronics. C was developed for programming OS. Pascal was conceptualized to teach proper programming techniques. But C++ is a general-purpose language. It well deserves the widely acknowledged nickname "Swiss Pocket Knife of Languages." C++ is a cross-platform language that can be used to create high-performance applications. C++ was developed by Bjarne Stroustrup, as an extension to the C language. C++ gives programmers a high level of control over system resources and memory. The language was updated 3 major times in 2011, 2014, and 2017 to C++11, C++14, and C++17. About C++ Programming Multi-paradigm Language - C++ supports at least seven different styles of programming. Developers can choose any of the styles. General Purpose Language - You can use C++ to develop games, desktop apps, operating systems, and so on. Speed - Like C programming, the performance of optimized C++ code is exceptional. Object-oriented - C++ allows you to divide complex problems into smaller sets by using objects. Why Learn C++? C++ is used to develop games, desktop apps, operating systems, browsers, and so on because of its performance. After learning C++, it will be much easier to learn other programming languages like Java, Python, etc. C++ helps you to understand the internal architecture of a computer, how computer stores and retrieves information. How to learn C++? C++ tutorial from Programiz - We provide step by step C++ tutorials, examples, and references. Get started with C++. Official C++ documentation - Might be hard to follow and understand for beginners. Visit official C++ documentation. Write a lot of C++ programming code- The only way you can learn programming is by writing a lot of code. Read C++ code- Join Github's open-source projects and read other people's code. C++ best programming language? T he answer depends on perspective and requirements. Some tasks can be done in C++, though not very quickly. For example, designing GUI screens for applications. Other languages like Visual Basic, Python have GUI design elements built into them. Therefore, they are better suited for GUI type of task. Some of the scripting languages that provide extra programmability to applications. Such as MS Word and even photoshop tend to be variants of Basic, not C++. C++ is still used widely, and the most famous software have their backbone in C++. This tutorial will help you learn C++ basic and the advanced concepts. Who uses C++? Some of today's most visible used systems have their critical parts written in C++. Examples are Amadeus (airline ticketing) Bloomberg (financial formation), Amazon (Web commerce), Google (Web search) Facebook (social media) Many programming languages depend on C++'s performance and reliability in their implementation. Examples include: Java Virtual Machines JavaScript interpreters (e.g., Google's V8) Browsers (e.g., Internet Explorer, Mozilla's Firefox, Apple's Safari, and Google's Chrome) Application and Web frameworks (e.g., Microsoft's .NET Web services framework). Applications that involve local and wide area networks, user interaction, numeric, graphics, and database access highly depend on C++ language. Why Use C++ C++ is one of the world's most popular programming languages. C++ can be found in today's operating systems, Graphical User Interfaces, and embedded systems. C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs. C++ is portable and can be used to develop applications that can be adapted to multiple platforms. C++ is fun and easy to learn! As C++ is close to C# and Java, it makes it easy for programmers to switch to C++ or vice versa Definition - What does C++ Programming Language mean? C++ is an object oriented computer language created by notable computer scientist Bjorne Stroustrop as part of the evolution of the C family of languages. Some call C++ “C with classes” because it introduces object oriented programming principles, including the use of defined classes, to the C programming language framework. C++ is pronounced "see-plus-plus." C++ Variables Variables are the backbone of any programming language. A variable is merely a way to store some information for later use. We can retrieve this value or data by referring to a "word" that will describe this information. Once declared and defined they may be used many times within the scope in which they were declared. C++ Control Structures When a program runs, the code is read by the compiler line by line (from top to bottom, and for the most part left to right). This is known as "code flow." When the code is being read from top to bottom, it may encounter a point where it needs to make a decision. Based on the decision, the program may jump to a different part of the code. It may even make the compiler re-run a specific piece again, or just skip a bunch of code. You could think of this process like if you were to choose from different courses from Guru99. You decide, click a link and skip a few pages. In the same way, a computer program has a set of strict rules to decide the flow of program execution. C++ Syntax The syntax is a layout of words, expression, and symbols. Well, it's because an email address has its well-defined syntax. You need some combination of letters, numbers, potentially with underscores (_) or periods (.) in between, followed by an at the rate (@) symbol, followed by some website domain (company.com). So, syntax in a programming language is much the same. They are some well-defined set of rules that allow you to create some piece of well-functioning software. But, if you don't abide by the rules of a programming language or syntax, you'll get errors. C++ Tools In the real world, a tool is something (usually a physical object) that helps you to get a certain job done promptly. Well, this holds true with the programming world too. A tool in programming is some piece of software which when used with the code allows you to program faster. There are probably tens of thousands, if not millions of different tools across all the programming languages. Most crucial tool, considered by many, is an IDE, an Integrated Development Environment. An IDE is a software which will make your coding life so much easier. IDEs ensure that your files and folders are organized and give you a nice and clean way to view them. Types of C++ Errors Another way to look at C++ in a practical sense is to start enumerating different kinds of errors that occur as the written code makes its way to final execution. First, there are syntax errors where the code is actually written in an illegible way. This can be a misuse of punctuation, or the misspelling of a function command or anything else that compromises the integrity of the syntax as it is written. Another fundamental type of error is a compiler error that simply tells the programmer the compiler was not able to do its work effectively. As a compiler language, C++ relies on the compiler to make the source code into machine readable code and optimize it in various ways. A third type of error happens after the program has been successfully compiled. Runtime errors are not uncommon in C++ executables. What they represent is some lack of designated resource or non-working command in the executable program. In other words, the syntax is right, and the program was compiled successfully, but as the program is doing its work, it encounters a problem, whether that has to do with interdependencies, operating system requirements or anything else in the general environment in which the program is trying to work. Over time, C++ has remained a very useful language not only in computer programming itself, but in teaching new programmers about how object oriented programming works.

Equally well known as Twenty-One. The rules are simple, the play is thrilling, and there is opportunity for high strategy. In fact, for the expert player who mathematically plays a perfect game and is able to count cards, the odds are sometimes in that player's favor to win. But even for the casual participant who plays a reasonably good game, the casino odds are less, making Blackjack one of the most attractive casino games for the player. While the popularity of Blackjack dates from World War I, its roots go back to the 1760s in France, where it is called Vingt-et-Un (French for 21). Today, Blackjack is the one card game that can be found in every American casino. As a popular home game, it is played with slightly different rules. In the casino version, the house is the dealer (a "permanent bank"). In casino play, the dealer remains standing, and the players are seated. The dealer is in charge of running all aspects of the game, from shuffling and dealing the cards to handling all bets. In the home game, all of the players have the opportunity to be the dealer (a "changing bank"). THE PACK The standard 52-card pack is used, but in most casinos several decks of cards are shuffled together. The six-deck game (312 cards) is the most popular. In addition, the dealer uses a blank plastic card, which is never dealt, but is placed toward the bottom of the pack to indicate when it will be time for the cards to be reshuffled. When four or more decks are used, they are dealt from a shoe (a box that allows the dealer to remove cards one at a time, face down, without actually holding one or more packs). OBJECT OF THE GAME Each participant attempts to beat the dealer by getting a count as close to 21 as possible, without going over 21. CARD VALUES/SCORING It is up to each individual player if an ace is worth 1 or 11. Face cards are 10 and any other card is its pip value. BETTING Before the deal begins, each player places a bet, in chips, in front of them in the designated area. Minimum and maximum limits are established on the betting, and the general limits are from $2 to $500. THE SHUFFLE AND CUT The dealer thoroughly shuffles portions of the pack until all the cards have been mixed and combined. The dealer designates one of the players to cut, and the plastic insert card is placed so that the last 60 to 75 cards or so will not be used. (Not dealing to the bottom of all the cards makes it more difficult for professional card counters to operate effectively.) THE DEAL When all the players have placed their bets, the dealer gives one card face up to each player in rotation clockwise, and then one card face up to themselves. Another round of cards is then dealt face up to each player, but the dealer takes the second card face down. Thus, each player except the dealer receives two cards face up, and the dealer receives one card face up and one card face down. (In some games, played with only one deck, the players' cards are dealt face down and they get to hold them. Today, however, virtually all Blackjack games feature the players' cards dealt face up on the condition that no player may touch any cards.) NATURALS If a player's first two cards are an ace and a "ten-card" (a picture card or 10), giving a count of 21 in two cards, this is a natural or "blackjack." If any player has a natural and the dealer does not, the dealer immediately pays that player one and a half times the amount of their bet. If the dealer has a natural, they immediately collect the bets of all players who do not have naturals, (but no additional amount). If the dealer and another player both have naturals, the bet of that player is a stand-off (a tie), and the player takes back his chips. If the dealer's face-up card is a ten-card or an ace, they look at their face-down card to see if the two cards make a natural. If the face-up card is not a ten-card or an ace, they do not look at the face-down card until it is the dealer's turn to play. THE PLAY The player to the left goes first and must decide whether to "stand" (not ask for another card) or "hit" (ask for another card in an attempt to get closer to a count of 21, or even hit 21 exactly). Thus, a player may stand on the two cards originally dealt to them, or they may ask the dealer for additional cards, one at a time, until deciding to stand on the total (if it is 21 or under), or goes "bust" (if it is over 21). In the latter case, the player loses and the dealer collects the bet wagered. The dealer then turns to the next player to their left and serves them in the same manner. The combination of an ace with a card other than a ten-card is known as a "soft hand," because the player can count the ace as a 1 or 11, and either draw cards or not. For example with a "soft 17" (an ace and a 6), the total is 7 or 17. While a count of 17 is a good hand, the player may wish to draw for a higher total. If the draw creates a bust hand by counting the ace as an 11, the player simply counts the ace as a 1 and continues playing by standing or "hitting" (asking the dealer for additional cards, one at a time). THE DEALER'S PLAY When the dealer has served every player, the dealers face-down card is turned up. If the total is 17 or more, it must stand. If the total is 16 or under, they must take a card. The dealer must continue to take cards until the total is 17 or more, at which point the dealer must stand. If the dealer has an ace, and counting it as 11 would bring the total to 17 or more (but not over 21), the dealer must count the ace as 11 and stand. The dealer's decisions, then, are automatic on all plays, whereas the player always has the option of taking one or more cards. SIGNALING INTENTIONS When a player's turn comes, they can say "Hit" or can signal for a card by scratching the table with a finger or two in a motion toward themselves, or they can wave their hand in the same motion that would say to someone "Come here!" When the player decides to stand, they can say "Stand" or "No more," or can signal this intention by moving their hand sideways, palm down and just above the table. SPLITTING PAIRS If a player's first two cards are of the same denomination, such as two jacks or two sixes, they may choose to treat them as two separate hands when their turn comes around. The amount of the original bet then goes on one of the cards, and an equal amount must be placed as a bet on the other card. The player first plays the hand to their left by standing or hitting one or more times; only then is the hand to the right played. The two hands are thus treated separately, and the dealer settles with each on its own merits. With a pair of aces, the player is given one card for each ace and may not draw again. Also, if a ten-card is dealt to one of these aces, the payoff is equal to the bet (not one and one-half to one, as with a blackjack at any other time). DOUBLING DOWN Another option open to the player is doubling their bet when the original two cards dealt total 9, 10, or 11. When the player's turn comes, they place a bet equal to the original bet, and the dealer gives the player just one card, which is placed face down and is not turned up until the bets are settled at the end of the hand. With two fives, the player may split a pair, double down, or just play the hand in the regular way. Note that the dealer does not have the option of splitting or doubling down. INSURANCE When the dealer's face-up card is an ace, any of the players may make a side bet of up to half the original bet that the dealer's face-down card is a ten-card, and thus a blackjack for the house. Once all such side bets are placed, the dealer looks at the hole card. If it is a ten-card, it is turned up, and those players who have made the insurance bet win and are paid double the amount of their half-bet - a 2 to 1 payoff. When a blackjack occurs for the dealer, of course, the hand is over, and the players' main bets are collected - unless a player also has blackjack, in which case it is a stand-off. Insurance is invariably not a good proposition for the player, unless they are quite sure that there are an unusually high number of ten-cards still left undealt. SETTLEMENT A bet once paid and collected is never returned. Thus, one key advantage to the dealer is that the player goes first. If the player goes bust, they have already lost their wager, even if the dealer goes bust as well. If the dealer goes over 21, the dealer pays each player who has stood the amount of that player's bet. If the dealer stands at 21 or less, the dealer pays the bet of any player having a higher total (not exceeding 21) and collects the bet of any player having a lower total. If there is a stand-off (a player having the same total as the dealer), no chips are paid out or collected. RESHUFFLING When each player's bet is settled, the dealer gathers in that player's cards and places them face up at the side against a clear plastic L-shaped shield. The dealer continues to deal from the shoe until coming to the plastic insert card, which indicates that it is time to reshuffle. Once that round of play is over, the dealer shuffles all the cards, prepares them for the cut, places the cards in the shoe, and the game continues. BASIC STRATEGY Winning tactics in Blackjack require that the player play each hand in the optimum way, and such strategy always takes into account what the dealer's upcard is. When the dealer's upcard is a good one, a 7, 8, 9, 10-card, or ace for example, the player should not stop drawing until a total of 17 or more is reached. When the dealer's upcard is a poor one, 4, 5, or 6, the player should stop drawing as soon as he gets a total of 12 or higher. The strategy here is never to take a card if there is any chance of going bust. The desire with this poor holding is to let the dealer hit and hopefully go over 21. Finally, when the dealer's up card is a fair one, 2 or 3, the player should stop with a total of 13 or higher. With a soft hand, the general strategy is to keep hitting until a total of at least 18 is reached. Thus, with an ace and a six (7 or 17), the player would not stop at 17, but would hit. The basic strategy for doubling down is as follows: With a total of 11, the player should always double down. With a total of 10, he should double down unless the dealer shows a ten-card or an ace. With a total of 9, the player should double down only if the dealer's card is fair or poor (2 through 6). For splitting, the player should always split a pair of aces or 8s; identical ten-cards should not be split, and neither should a pair of 5s, since two 5s are a total of 10, which can be used more effectively in doubling down. A pair of 4s should not be split either, as a total of 8 is a good number to draw to. Generally, 2s, 3s, or 7s can be split unless the dealer has an 8, 9, ten-card, or ace. Finally, 6s should not be split unless the dealer's card is poor (2 through 6).
