15 Slide 15 Tunnel Load

16 Slide 16 Primary & Backup LSP Path

17 Slide 17 MPLS Traffic Management Network Centric Network Monitoring and quantifying Characterize traffic and monitor resource utilization Quantifying traffic across the network or its elements in terms of bytes and packets (in and out) Network path, link, LSP Monitor operational status and availability Discover network topology Present physical and logical network topology Monitor network connectivity Pinpoint network integrity problem Provision MPLS tunnels

18 Network Status Display Semi Real Time Network View View of table/tree structure of networks, areas, hubs/pops, devices, LSPs and the related attributes Primary attributes: AS number, Area/Level/Region IDs, location, vendors, devices limitation, circuit bandwidth, RSVP Bandwidth,LSP utilization, and LSP path Ability to sync with real time network to update the view Tunnel Path Analysis Copyright 2000, WANDL, Inc. Slide 18

19 Slide 19 Network Status Display Network Status Changes Display/report the updates of network components and their related attributes (new, deleted, and missed trunks, trunk capacity changes), (new LSP, deleted LSP, updated LSP in bandwidth, route changes, priority, info) Network Play Back (historical events) Replay network status/topology changes Replay the LSPs re-route activities
