US 2019/0296965 A1 · TARGETED SELECTION OF CASCADE PORTS

Abstract

Techniques are described for providing targeted selection of cascade ports of an aggregation device. In one example, the disclosed techniques enable dynamic assignment of active and backup cascade ports of an aggregation device for each extended port of satellite devices. In this example, rather than allocating resources for each of the extended ports of the satellite devices on all of the cascade ports of the aggregation device, the aggregation device instead allocates resources for each of the extended port only on the assigned active and backup cascade ports for the respective one of the extended ports of the satellite devices. The techniques are also described for providing traffic steering to a backup cascade port in the event the assigned active cascade port is unreachable, and, if the cascade port remains unreachable for a specified duration, the aggregation device may assign new active and backup cascade ports for the extended port.

Dependent claims

A method comprising:

assigning, by an aggregation device that manages interface configuration of a satellite device coupled to the aggregation device by a plurality of cascade ports, an active cascade port and a backup cascade port from the plurality of cascade ports for each extended port of a plurality of extended ports of the satellite device;
and
allocating, by the aggregation device, one or more resources of the aggregation device only for the assigned active cascade port and the assigned backup cascade port for each extended port of the plurality of extended ports of the satellite device.

An aggregation device comprising:

a memory and one or more processors in communication with the memory configured to:
manage interface configuration for a satellite device coupled to the aggregation device;
assign an active cascade port and a backup cascade port from a plurality of cascade ports for each extended port of a plurality of extended ports of the satellite device;
and
allocate one or more resources of the aggregation device only for the assigned active cascade port and the assigned backup cascade port for each extended port of the plurality of extended ports of the satellite device.

A non-transitory computer-readable storage medium storing instructions that when executed cause one or more programmable processors of an aggregation device to:

manage interface configuration for a satellite device coupled to the aggregation device;
assign an active cascade port and a backup cascade port from a plurality of cascade ports for each extended port of a plurality of extended ports of the satellite device;
and
allocate one or more resources of the aggregation device only for the assigned active cascade port and the assigned backup cascade port for each extended port of the plurality of extended ports of the satellite device.
