What is this draft about?A solution architecture of virtual PE
Allow physical control plane and data plane separationAllow IP VPN (RFC 4364) to be extended into end-systems/devicesAllow large scale dynamic orchestration supportScope Anywhere, DC and beyondSlide3
Virtual PE DefinitionA virtual PE (vPE): a BGP IP VPN PE software instance which may reside in any network or computing devices.
vPE-F: vPE Forwarding PlanevPE-C: vPE Control PlanevPE-C and vPE-F can be decoupled, they may reside in the same physical device, or most often in different physical devices.Slide4
vPE Architecture and Design Options
Design Options1. vPE-F location1a. End device, such as a server1b. Top of the Rack (ToR)1c. Any other devices/systems, e.g., a Gateway router2. vPE-C location2a. Controller (centralized or distributed)2b. Same location as vPE-F, using mp-bgp for signaling3. Orchestration models3a. Push model: push IP VPN provisioning from NMS or other central control provisioning systems to the IP VPN network elements.3b. Pull model: pull from network elements to network management/AAA based upon data plane or control plane activity. Slide5
