Abstract
Methods, systems, and computer program products for implementing link redundancy in a media gateway are provided according to one method, a media gateway link protection group is provisioned to associate with a common VLAN a common virtual local area network (VLAN) primary and secondary links associated with at least one line card in a media gateway. The primary and secondary links are connected using a cross connection between ports associated with the at least one line card. At run time, traffic is automatically bridged between the primary and secondary links using the common VLAN and the cross connection.
Claims22
A method for implementing link redundancy in a media gateway, the method comprising:
- (a) provisioning a media gateway link protection group to associate with a common virtual local area network (VLAN) primary and secondary links from at least one line card located in a media gateway;
- (b) connecting the primary and secondary links using a cross-connection between ports associated with the at least one line card;
- and
- (c) at run time, automatically bridging traffic between the primary and secondary links using the common VLAN and the cross connection.
A media gateway comprising:
- (a) at least one line card within the media gateway being connected to an active link and a standby link;
- (b) a cross connect for connecting the active and standby links via the at least one line card;
- and
- (c) wherein the at least one line card is adapted to automatically bridge traffic between the active and standby links using the common VLAN and the cross connect.
A computer program product comprising computer executable instructions embodied in a computer readable medium for performing steps comprising:
- (a) provisioning a media gateway link protection group to associate with a common virtual local area network (VLAN) primary and secondary links from at least one line card located in a media gateway;
- (b) connecting the primary and secondary links using a cross-connection between ports associated with the at least one line card;
- and
- (c) a run time, automatically bridging traffic between the primary and secondary links using the common VLAN and the cross connection.
