PBB Connection Models Multi-Domain Future work and Conclusions

Provider Backbone Bridges (1)

Provider Backbone Bridges (PBB) implementation IEEE 802.1ah standard. Forward customers frames over a service providers backbone network. Separate backbone network from customers (MAC-header) Increase number of VLANs (I-SID)

PBB Connection Models Multi-Domain Future work and Conclusions

Conclusions

Connection models Endpoint configuration, connection model based on situation Multi-Domain Peer PBBN is easiest model to configure and maintain between network exchange points PBB PBB is mature enough to be used in prolonged testing environments
