Pinning and protection on link aggregation groups

1. 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.

2. The method of claim 1 , further comprising:

looking up a media access control (MAC) address destination and a corresponding VLAN value to determine a match;

retrieving a forwarding data structure associated with the match; and

determining one or more links in the LAG, capable of receiving traffic, based on the forwarding data structure.

3. The method of claim 2 , further comprising:

receiving the traffic; and

sending the traffic on the determined one or more LAG links.

4. The method of claim 2 , further comprising:

receiving the traffic;

detecting a link failure of one of the determined one or more LAG links;

removing the failed link from the LAG; and

sending the traffic on the remaining, determined one or more LAG links.

5. 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.

6. The method of claim 5 , further comprising:

looking up a media access control (MAC) address destination and a corresponding VLAN value to determine a match;

retrieving a forwarding data structure associated with the match; and

determining one or more links in the LAG, capable of receiving traffic, based on the forwarding data structure.

7. The method of claim 6 , further comprising:

receiving the traffic; and

sending the traffic on the determined one or more links in the LAG.

8. The method of claim 6 , further comprising:

receiving the traffic;

detecting a link failure in one of the determined one or more links in the LAG;

removing the failed link from the LAG; and

sending the traffic on the remaining, determined one or more links in the LAG.

9. 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.

10. The device of claim 9 , where the processor is further to:

look up a media access control (MAC) address destination and a corresponding VLAN value to determine a match;

retrieve a forwarding data structure associated with the match; and

determine one or more LAG links capable of receiving traffic based on the forwarding data structure.

11. The device of claim 10 , where the processor is further to:

send the traffic on the determined one or more LAG links.

12. The device of claim 10 , where the processor is further to:

detect a link failure in one of the determined one or more LAG links;

remove the failed link from the LAG; and

send the traffic on the remaining, determined one or more LAG links.

13. A computer-readable memory device that stores instructions executable by one or more processors, the computer-readable memory device comprising:

one or more instructions for defining a class of service for point-to-point services;

one or more instructions for defining a class of service for multi-point services;

one or more instructions for associating a link in a link aggregation group (LAG) to a first packet buffer queue for the point-to-point services;

one or more instructions for associating the link in the LAG to a second packet buffer queue for the multi-point services;

one or more instructions for allocating a guaranteed particular bandwidth to each of the first packet buffer queue and the second packet buffer queue;

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.

14. The computer-readable memory device of claim 13 , further comprising:

one or more instructions for looking up a media access control (MAC) address destination and a corresponding VLAN value to determine a match;

one or more instructions for retrieving a forwarding data structure associated with the match; and

one or more instructions for determining one or more links in the LAG, capable of receiving traffic, based on the forwarding data structure.

15. The computer-readable memory device of claim 14 , further comprising:

one or more instructions for receiving the traffic; and

one or more instructions for sending the traffic on the determined one or more LAG links.

16. The computer-readable memory device of claim 14 , further comprising:

one or more instructions for receiving the traffic;

one or more instructions for detecting a link failure of one of the determined one or more LAG links;

one or more instructions for removing the failed link from the LAG; and

one or more instructions for sending the traffic on the remaining, determined one or more LAG links.
