Claim Text:
1. A device deployed in a network for providing a virtual circuit service, the device comprising: a packet switch constructed to (i) correlate an identifier included in a received packet with first information representing at least one of a circuit identifier, a circuit bundle identifier, and a status identifier included in a circuit table, (ii) retrieve from a forwarding table, output interface information corresponding to the first information, and (iii) determine whether the output interface information corresponds to a circuit bundle with an active virtual circuit by identifying whether (a) the output interface information specifies an output circuit bundle identifier, and (b) the output circuit bundle identifier corresponds to second information, in a circuit bundle table, specifying the active virtual circuit, wherein the circuit bundle table includes information specifying a type of virtual circuits that included in each respective circuit bundle; and wherein the circuit bundle table includes data indicating whether a Media Access Control address withdraw message should be sent in a case where the active virtual circuit fails, and data indicating whether individual traps should be sent for the circuit bundle.
