Abstract
In one embodiment, active links are added to, and removed from, a multichassis link bundle with one side of the multichassis link bundle terminated on multiple devices of a multichassis device. In one embodiment, adding active links includes selecting which particular device to which to add an active link to the multichassis link bundle based on a device priority of each of the multiple devices, with a device priority of a given device being based on a current number of active links associated with the given device.
Claims20
A method, comprising:
- adding and removing active links to and from a multichassis link bundle with one side of the multichassis link bundle terminated on a plurality of devices of a multichassis device;
- wherein said adding active links includes selecting which particular device of the plurality of devices to which to add an active link to the multichassis link bundle based on a device priority of each of the plurality of devices;
- and
- wherein a device priority of a given device is based on a current number of active links associated with the given device.
A method, comprising:
- in response to a particular link becoming available to add to a multichassis link bundle with one side of the multichassis link bundle terminated on a plurality of devices of a multichassis device:
- identifying a lower device priority active link currently included in the multichassis link bundle with the lower device priority active link terminating on one of the plurality of devices having a lower device priority than another of the plurality of devices terminating the particular link;
- removing the lower device priority active link from the active links of the multichassis link bundle;
- and
- adding the particular link to the active links of multichassis link bundle,
- wherein a device priority of a link is determined based on a current number of active links associated with a device of the plurality of devices on which the link is terminated.
A multichassis device, comprising:
- a plurality of packet switching devices, with each of the plurality of packet switching devices terminating one side of at least one link of a plurality of links, wherein a multichassis link bundle includes the plurality of links;
- and
- a main packet switching device terminating each link in the plurality of links,
- wherein links of the plurality of links are added and removed from the multichassis link bundle based on a device priority associated with each of the plurality of packet switching devices, and the device priority of each particular packet switching device of the plurality of packet switching devices is determined based on a current number of active links associated with said particular packet switching device.
