ROUTING TABLES Routing Table for Virtual circuit networks • virtual circuit identifier determines the destination Routing table for datagram networks Specialized Routing Flooding · Principle of flooding : a node (or a packet switch) forwards an incoming packet to all ports except to the one it arrived on. · Each node (a switch) performs the flooding process such that the packet will reach the destination as long as at least one path exists between the source and the destination. · Flooding is a useful o when the information in the routing tables is not available, such as during system startup, o when survivability is required, such as in military networks. o when the source needs to send a packet to all hosts connected to the network (i.e., broadcast delivery). • Flooding generates vast numbers of duplicate packets In figure, initially one packet arriving at node 1 triggers three packets to nodes 2, 3, and 4. In the second phase nodes 2, 3, and 4 send two, two, and thre...

OSPF Link State Update In response to LS request or trigger router will send new LS info trigger, using the LS update message Contents are composed of link state advertisements (LSA’s) LS update message is acknowledged using LS ack pkt to ensure that the flooding algorithm is reliable; Link state acknowledgement packets consist of a list of LSA headers. BGP (Border Gateway Protocol): The de facto standard for inter-AS routing, BGP: glues the whole Internet together   P ath Vector protocol Uses TCP (service port: 179) Similar to Distance Vector protocol. Each Border Gateway broadcast to neighbors (peers) e ntire path (i.e., sequence of AS’s) to destination BGP is an exterior gateway protocol (EGP), which means that it performs routing between multiple autonomous systems or domains and exchanges routing and reachability information with other BGP systems. The information exchanged among BGP routers allow a router to construct a graph of AS’s and each AS...

Packet Switching Networks:Traffic Management

Traffic Management · The main objectives of traffic management are efficient use of network resources & deliver QoS. · Traffic Management is classified into three levels that are Packet level, Flow level and  Flow aggregated level. Traffic Management at Packet Level o Queueing & scheduling at switches, routers and multiplexers. The path traversed by packet through a network can be modeled as sequence of Queueing systems as shown in above figure. A packet traversing network encounters delay and possible loss at various multiplexing points. End-to-end performance is sum of the individual delays experienced at each system. Average end-to-end delay is the sum of the individual average delay. To meet the QoS requirements of multiple services, a queueing system must implement strategies for controlling the transmission bit rates. The different strategies for Queue scheduling are:- 1. FIFO QUEUEING 2. PRIORITY QUEUEING 3. FAIR QUEUEING 4. WEIGHTED FAIR...
