Abstract:
A network device may detect a reduced switching fabric bandwidth due to switching fabric degradation of a switching fabric. The network device may allocate the reduced switching fabric bandwidth to one or more interfaces of a packet processor. The network device may determine a first maximum reservable bandwidth for an interface of the one or more interfaces. The network device may identify a reserved bandwidth for the interface. The network device may determine an unreserved bandwidth for the interface based on the first maximum reservable bandwidth and the reserved bandwidth. The network device may advertise the unreserved bandwidth, for the interface, to a neighbor network device that communicates with the network device via the interface. The network device may provide an instruction, to the neighbor network device, for the neighbor network device to update a second maximum reservable bandwidth associated with the neighbor network device.
