Routing v/s Routed Protocols in Computer Network; Unicast Routing - Link State Routing; Distance Vector Routing (DVR) Protocol; Route Poisoning and Count to infinity problem in Routing; Onion Routing; Configuration of Router on a stick; Internet Control Message Protocol (ICMP) Hot Standby Router Protocol (HSRP There is a famous problem that illustrates this issue. It is called the two-army problem. Imagine that a white army is encamped in a valley, as shown in Fig. 6.2. On both of the surrounding hillsides are blue armies. The white army is larger than either of the blue armies alone, but together the blue armies are larger than the white army. If either blue army attacks by itself, it will be defeated, but if the two blue armies attack simultaneously, they will be victorious What are the criteria necessary for an effective and efficient network? 1: 2105: Synopsys: Networking-Grids: 1: 1494: Nvidia: Interprocess Communication (IPC) 1: 1843: Nvidia: Pipes In Programming: 1: 1719: Nvidia: Sockets Meaning: 1: 1318: Nvidia: what data structure do we use in computer networks? 2: 2330: Amdocs: What is TDM? 1: 1943: Synopsys: What is WDM? 1: 1959: Synopsys: What is FDM? 1: 2245: Synopsy It's not the same problem, mainly because when closing one of the segments should be the last segment, so acknowledgements are not enough, you must use timers to decide if a stage has ended (you know those stages), so that you can decide that you must resend a connection close request of just close the connection because because it has passed too much time since the second connection close request is sent The steps 1, 2 establish the connection parameter (sequence number) for one direction and it is acknowledged. The steps 2, 3 establish the connection parameter (sequence number) for the other direction and it is acknowledged. With these, a full-duplex communication is established

If queue is empty there will be less or no delay. If more number of packets are arriving in a short or no time interval, queuing delay will be large. Less the number of servers/links, greater is the queuing delay. 4. Processing delay: Now the packet will be taken for processing which is called processing delay From Wikipedia, the free encyclopedia Positions of the armies. Armies A1 and A2 need to communicate but their messengers may be captured by army B. In computing, the Two Generals' Problem is a thought experiment meant to illustrate the pitfalls and design challenges of attempting to coordinate an action by communicating over an unreliable link It is very extensively used in computer communication and tele-communication. Sharing of the channel is accomplished by dividing available transmission time on a medium among users. It exclusively uses the Digital Signaling instead of dividing the cable into frequency bands. TDM splits cable usage into time slots The Network Layer of the OSI Model is responsible for providing logical addressing, which routers use to select best path for routing packets. There are two types of packets used at this layer : Data Packets -. The user data is transferred in the inter-network by these data packets Platform to practice programming problems.

What is Computer Network? A computer network is a set of devices connected through links. A node can be computer, printer, or any other device capable of sending or receiving the data. The links connecting the nodes are known as communication channels. Computer Network uses distributed processing in which task is divided among several computers. Instead, a single computer handles an entire task, each separate computer handles a subset Computer Network Computer Engineering MCA. When there are more than one user who desire to access a shared network channel, an algorithm is deployed for channel allocation among the competing users. The network channel may be a single cable or optical fiber connecting multiple nodes, or a portion of the wireless spectrum. Channel allocation algorithms allocate the wired channels and bandwidths.

What is byte stuffing in computer networks? Computer Engineering Computer Network MCA. Purpose of Byte Stuffing. In Data Link layer, the stream of bits from physical layer are divided into data frames. The data frames can be of fixed length or variable length. In variable - length framing, the size of each frame to be transmitted may be different. So, a pattern of bits is used as a delimiter. Computer Network Computer Engineering MCA. ALOHA is a multiple access protocol for transmission of data via a shared network channel. It operates in the medium access control sublayer (MAC sublayer) of the open systems interconnection (OSI) model. Using this protocol, several data streams originating from multiple nodes are transferred through. Multicast routing in computer networks . 1998. Abstract. Multicast routing is a network-layer function that constructs paths along which data packets from a source are distributed to reach many, but not all, destinations in a communication network. Multicast routing sends a single copy of a data packet simultaneously to multiple receivers over a communication link that is shared by the paths. A Computer Science portal for geeks.

A computer network provides more than one protocol to the network applications. For example, TCP and UDP are two transport layer protocols that provide a different set of services to the network layer Example of Hamming Code Generation. Suppose a binary data 1001101 is to be transmitted. To implement hamming code for this, following steps are used: 1. Calculating the number of redundancy bits required. Since number of data bits is 7, the value of r is calculated as. 2r > m + r + 1. 24 > 7 + 4 + 1. Therefore no. of redundancy bits = 4
