The structure of the paper is as follows. In Secti on 2, we show an overview of OLS Rrouting protocol. In Section 3, we design and introduce the implementation of ourtestbed. In Section 4, we give experimental results and make the comparison. Finally,conclusions are given in Section 5.[r]

Benefits of Link-State Routing •Fast convergence: changes are reported immediately by the source affected.•Robustness against routing loops:–Routers know the topology. –Link-state packets are sequenced and acknowledged. •By careful (hierarchical) netw[r]

Distance Vector Routing ProtocolsMost routing protocols fall into one of two classes: distance vector or link state. The basics of distance vector routing protocols are examined here; the next section covers <[r]

The major problem with the distance vector algorithm is that it takes some time to converge to a new understanding of the network. The bandwidth and traffic requirements of this algorithm can also affect the performance of the network. The major advantage of the distance[r]
