ABSTRACT:
Methods and apparatus for encapsulating a packet or frame for transmission in a storage area network are disclosed. A packet or frame compatible with a standard protocol employed in the storage area network is received or generated. The packet or frame is then encapsulated with a virtual storage area network identifier. The packet or frame may further be encapsulated with at least one of a TTL value, MPLS information, and a type of traffic to be carried by the packet or frame. For instance, the type of traffic to be carried by the packet or frame may include Ethernet, Fibre Channel, and Infiniband. Once encapsulated, the encapsulated packet or frame is sent over the storage area network. For instance, the encapsulated packet or frame may be generated as well as transmitted by a switch over an inter-switch link in the storage area network.
