802.1Qcy – VDP Extension to Support NVO3

The full title of this PAR is “Standard for Local and Metropolitan Area Networks: Bridges and Bridged Networks: Amendment: Virtual Station Interface (VSI) Discovery and Configuration Protocol (VDP) Extension to Support Network Virtualization Overlays Over Layer 3 (NVO3)”.

This standard specifies extensions to VDP to support using the protocol between an end station and a device doing encapsulation/decapsulation for NVO3. The extensions will include adding format types that include Internet Protocol (IP) addresses and enhancing indication of migration events.

Bridges, as specified by this standard, allow the compatible interconnection of information technology equipment attached to separate individual LANs.

This amendment extends VDP protocol to fulfill the requirements for the control plane protocol between the virtualized end device (end station) and the external network virtualization edge (e.g. bridge or router) in an NVO3 network.

This project was originally labeled P802.1Qcn, but was renamed to P802.1Qcy to avoid ambiguity with the protocol QCN as defined in Std IEEE 802.1Q-2010
