Abstract

Voice over IP technology integrates data and voicenetworks and offers flexibility by supplying device interoperabilityusing standards-based protocols. Routing is an essential datanetworking function that provides an efficient real-time datadelivery VoIP requires. Best-effort networks leverage InteriorGateway Protocol technologies to determine paths for routingpackets between hosts. Architects for best-effort networks provideservices by over-provisioning the links and routers so that networkcongestion does not introduce unwanted levels of latency, jitter, andpacket loss. Route re-convergence can be detrimental to VoIP usersin the middle of a conversation, as it impacts both latency and jitter.This paper studies how VoIP performance can be affected bydifferent routing behaviors which include Routing InformationProtocol, Open Shortest Path First and Enhanced Interior GatewayRouting Protocol. Network modeling and simulation have beencarried out with OPNET Modeler to evaluate and compareperformances.
