v37 v38 237 237 238 238 ==== Multi-protocol Network Troubleshooting with Pathtrace protocol ==== 239 We showcase a proposed protocol to trace flow pathsbetween two end hosts of a given network topology.239 We showcase [wiki:GEC24Agenda/EveningDemoSession/GEC24demo-pathtrace.pdf a proposed protocol to trace flow paths (poster here)] between two end hosts of a given network topology. 240 240 241 241 For this demo deployment the protocol is implemented using a network function (NF) which is connected to legacy L2 switches. Trace packets traverse the NF through the use of ACLs on the L2 devices, allowing for retrofitting of legacy networks for accurate path tracing through L2 while not affecting normal packet forwarding paths. A custom client has been created (akin to the traceroute tool) to be deployed on hosts to originate tracer packets, which are injected into the network towards the desired endpoint, which the NF records at each hop and uses to return path information to the administrator. 242 242 243 The demo will show path tracing across an arbitrary L2 topology deployed using VTS, with live inspection of STP state and failure injection to show tracing through path changes between the same endpoints. 243 The demo will show path tracing across an arbitrary L2 topology deployed using VTS, with live inspection of STP state and failure injection to show tracing through path changes between the same endpoints. 244 244 245 245 Participants:
