135.46.57.14 in binary is 10000111.00101110.00111001.00001110. Again the prefix points us to one of the Interfaces, so we take the 22 MSB's, or 10000111.00101110.00111000.00000000. Back to decimal, this is 135.46.56.0, which points to Interface 0, so that’s where it is routed.

every other node that receives them from the neighbors of S, until they arrive at the destination. When reactive routing protocols such as DSR or

As we all know, the growth of computer networks continues to rapidly grow. The digital revolution has changed the way we work and communicate almost beyond recognition. Provided that, foreseeing the changes and potential compatibility problems, in the mid nineteen eighties, the international standard organization (ISO) developed a networking reference model to standardize how network systems communicate with each other. It is a logical model for how network systems are supposed to communicate with each other. It breaks down the different components of the network communication and puts them into layers which reduce complexity. This reference model consists of seven layers: Application Layer, Presentation Layer, Session Layer, Transport Layer, Network Layer, Data Link Layer, and the Physical Layer. Each layer provides a service to the layer above it in the protocol specification and then communicates with the same layer’s software or hardware on other computers. It's important to realize, that these layers are separated into 2 sets: Transportation Set (Laters 1- 4) and Application Set (Layers 5 – 7). More importantly, the OSI model is 7 logical

In a figure all ways from S to D incorporate hosts that are outside the request zone. Accordingly, there is no surety that a way can be discovered comprising just of the hosts in a picked request zone. In this manner, if a route is not found inside of a suitable timeout period, our convention Wows S to start another route disclosure with an extended request zone – in our simulations, the extended zone incorporates the whole system space. in this case the inactivity in deciding the route to D be longer.

| Given a network topology and three or more routers and an IPv4 addressing scheme, implement RIPv1 routing protocol and confirm layer 3 connectivity.

In this example, we have three routers A, B and C. C’s E0 is directly connected to 192.168.3.0. And C’s routing table is (192.168.3.0; 0; E0) which shows that 192.168.3.0 is 0 hop away. RIP (Routing Information Protocol), running on C, tells B that 192.168.3.0 is reachable through C with a distance of 0. B adds 1 hop to the distance and enters the route to 192.168.3.0 into its own routing table which becomes (192.168.3.0; 1; S1). Now RIP is running on B and tells C that 192.168.3.0 is 1 hop away. Similarly, C adds 1 hop to the distance and enters the route to 192.168.3.0 into its own routing table which becomes (192.168.3.0; 2; S1).

This protocol use Dijkstra algorithm. It maintains a complex data base, also called as link state database, which contains full information about the remote routers and the exact network topology. The goal from this protocol is to provide similar information about network connection to each router, so each router can calculate the best route to each network this is happen when each router generates information about itself and pass these information to other routers in the network so each router make a copy of this information without changing it.

DSDV is a proactive, hop-by-hop distance vector routing protocol where the routing table is maintained by each and every network node. The routing table consists of all the nodes required to reach destination also including the nodes to which packets are not sent. The routing table is kept updated at every time after each entry. In order to avoid the routing loops, DSDV uses the concept of sequence numbers to maintain the originality of route at all times. For the network in figure. 1 below, the routing table for node A can be seen in table. 1 which contains information about all possible paths reachable by node A, along with the next hop, number of hops and sequence number.

In simulated network the source node designated as1 initiates the routing procedure by sending RREQ or Route Request message to its surrounding nodes. The RREQ message sent by the source node is denoted in the color green. The other RREQ messages are shown in cyan, yellow, black etc. The source node 1 is sending the RREQ message to its neighbour nodes 5, 6, 9, 11 and 13 and the links are formed shown by the green line. Every time node 5,6,9,11,13 is sending the RREQ message to its neighbour and the links are formed.

The purpose of this paper is to provide a better understanding of switching and routing used in a network environment and familiarize the reader with various hardware and software associated with there functions. This paper will look at some switching concepts that will include store and forward switching, cut through switching, fragment free switching, and V-Lan. This paper will also cover routing concepts, along with some comparisons including routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols.

forwarded, a route is already known and can be used immediately. Once the routing tables

Key tools utilized, variable length subnet masking and route summarization are explained as well. Here choosing the appropriate routing protocol is equally critical for a successful design. To implement different masks for the same major network it is necessary to have a routing protocol that supports VLSM. Such routing protocols are called classless routing protocols. They carry the mask information along with the route advertisements therefore allowing for the support of more than one mask.

The algorithm uses fixed "metrics" for route comparisons. The fixed metrics could be time delay, cost, or some other value used to compare routes. In the following network, the numbers represent the cost to transverse the link.

The OSI model defines internetworking in terms of a vertical stack of seven layers. The upper

Networks are usually very humungous which makes the implementation of routing algorithms really tough. Hence there is a need to divide the networks into autonomous systems. AS are groups of networks and routers which are under the control of a single admin. Routing can broadly be divided into interior and exterior routing based on whether routing is inside an autonomous system or not.
