Abstract
A resource optimization processor is disclosed for inclusion in peer routers. The resource optimization processor performs a method for resource optimization of the routers. The method includes disabling an inter-switch link (ISL) between peer routers and monitoring downstream links between a primary router and downstream devices connected to the primary router. The method further includes identifying a failure of at least one downstream link and enabling the ISL between the first router and the second router for the failed downstream link upon identification of the failure.
Claims20
A method for resource optimization in a multicast network, the method comprising:
- disabling, by a first network device, an inter-switch link (ISL) between the first network device functioning as a designated router and a second network device functioning as a proxy router to prevent a duplication of multicast traffic from the first network device to the second network device;
- monitoring, by the first network device, downstream links between the first network device and downstream devices coupled to the first network device;
- identifying, by the first network device, a failure of at least one downstream link coupled to the first network device;
- and
- determining, by the first network device, the ISL to be an egress port for traffic destined to the failed downstream link in response to identification of the failure.
A network device functioning as a designated router in a multicast network, the network device comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing instructions, which when executed by the processor cause the processor to perform a method, the method comprising:
- disabling an inter-switch link (ISL) between the network device and a peer network device functioning as a proxy router to prevent a duplication of multicast traffic from the network device to the peer network device;
- monitoring the downstream links between the network device and downstream devices coupled to the network device;
- identifying a failure of at least one downstream link coupled to the network device;
- and
- determining the ISL to be an egress port for traffic destined to the failed downstream link upon identification of the failure.
A non-transitory computer-readable medium storing instructions executable by a processor of a network device to cause the processor to perform a method, the method comprising:
- disabling an inter-switch link (ISL) between the network device functioning as a designated router and a peer network device functioning as a proxy router to prevent a duplication of multicast traffic from the network device to the second network device;
- monitoring downstream links between the network device and downstream devices coupled to the network device;
- identifying a failure of at least one downstream link coupled to the network device;
- and
- determining the ISL to be an egress port for traffic destined to the failed downstream link upon identification of the failure.
