Abstract
A device may assign a virtual local area network (VLAN) to one or more specific links in a link aggregation group (LAG), and send traffic from the VLAN on the assigned one or more specific LAG links. Traffic from the same VLAN may be sent on one link in the LAG by selecting a hashing criterion or by pinning the VLAN to a primary link in the LAG and another link for redundancy purposes.
Claims16
A computing device-implemented method comprising:
- defining, by the computing device, a class of service for point-to-point services;
- defining, by the computing device, a class of service for multi-point services;
- associating, by the computing device, a link in a link aggregation group (LAG) to a first packet buffer queue for the point-to-point services;
- associating, by the computing device, the link in the LAG to a second packet buffer queue for the multi-point services;
- allocating, by the computing device, a guaranteed particular bandwidth to each of the first and second packet buffer queues;
- assigning a virtual local area network (VLAN) to the link in the LAG;
- admitting the VLAN to a queue, of the first packet buffer queue or the second packet buffer queue, corresponding to the assigned link in the LAG when a bandwidth of the VLAN does not exceed a bandwidth of the queue;
- and
- sending traffic from the VLAN on the assigned link in the LAG.

A computing device-implemented method comprising:
- assigning, by the computing device, a virtual local area network (VLAN) to a specific link in a link aggregation group (LAG);
- admitting, by the computing device, the VLAN to a queue corresponding to the assigned specific link in the LAG when a bandwidth of the VLAN does not exceed a bandwidth of the queue;
- and
- sending, by the computing device, traffic from the VLAN on the assigned specific link in the LAG, via the queue.

A device comprising:
- a memory to store a plurality of instructions;
- and
- a processor to execute instructions in the memory to:
- define a class of service for point-to-point services,
- define a class of service for multi-point services,
- associate a specific link in a link aggregation group (LAG) to a first packet buffer queue for the point-to-point services,
- associate the specific link in the LAG to a second packet buffer queue for the multi-point services,
- allocate a guaranteed particular bandwidth to each of the first packet buffer queue and the second packet buffer queue,
- assign a virtual local area network (VLAN) to the specific link in the LAG,
- admit the VLAN to the first packet buffer queue or the second packet buffer queue when a bandwidth of the VLAN does not exceed a bandwidth of the first packet buffer queue or the second packet buffer queue;
- and
- send traffic from the VLAN on the specific link in the LAG.

- one or more instructions for assigning a virtual local area network (VLAN) to the link in the LAG;
- one or more instructions for admitting the VLAN to a queue, of the first packet buffer queue or the second packet buffer queue, corresponding to the assigned link in the LAG when a bandwidth of the VLAN does not exceed a bandwidth of the queue;
- and
- one or more instructions for sending traffic from the VLAN on the assigned link in the LAG.
