Abstract:
A method for expanding a service VLAN space of a provider network is provided. A bit number occupied by a taq protocol identifier (TPID) in a TPID field is reduced to leave a plurality of spare bits. The spare bits of the TPID field is then used to represent a first portion of a service VLAN identifier. A VLAN identifier field of a tag control information (TCI) field is used to represent a second portion of the service VLAN identifier. The first and second portions are then combined to obtain the service VLAN identifier of the packets completely.
