Abstract
The invention is directed to the use of Provider Backbone Bridging (PBB) technology with Shortest Path Bridging, also called Provider Link State Bridging (PLSB) technology in the context of data centers and virtualized physical servers infrastructures. Virtual servers can be located anywhere inside the data center, or across different data centers, and still act as though they are physically adjacent and share the same Ethernet connectivity. Ethernet virtual machine VLan memberships are mapped to PBB Service Identifiers (I-SIDs). PBB I-SIDs extend the connectivity model to every Ethernet switches in the local, metropolitan or wide area networks. PLSB complements the connectivity by providing dynamic distribution and mapping of I-SID endpoints in the PBB domain. Virtual servers can then be added, removed or transferred to another point in the network and PLSB adjusts the VLan/I-SID specific connectivity pattern to match the physical distribution of the servers.
