Multi-device link aggregation
First Claim
1. A system comprising:
- a first multi-device link aggregation (MDLA) device;
a second MDLA device; and
an MDLA internal link connecting the first MDLA device to the second MDLA device;
wherein each of the interconnected first and second MDLA devices is connected to a common link aggregation (LAG) partner device by an aggregated link, respectively and wherein, if one of the first or second MDLA devices fails, data traffic of the associated aggregated link to the failed MDLA device is forwarded by the other non-failed MDLA device.

Abstract
The invention relates to multi-device link aggregation (MDLA). A first MDLA device is connected to a second MDLA device by an MDLA internal link. Each of the interconnected first and second MDLA devices is connected to at least one common link aggregation (LAG) partner device by an aggregated link, respectively. Typically, the first and second MDLA devices exchange protocol data units (PDUs) to detect devices that are connected to both the first and second MDLA devices such that they are able to trick the detected devices into behaving as though the two MDLA devices are a single device. If one of the MDLA devices fails, traffic of the associated aggregated link to the failed MDLA device can be automatically forwarded by the other non-failed MDLA device.
