Computer network method and device using link aggregation

摘要

A method and device of link aggregation in computer networking, wherein data originally scheduled for forwarding by a scheduled data port are diverted for forwarding by a backup data port assigned to the scheduled data port upon detection that the scheduled data port is connected to a data link which is not capable of data traffic even though the data port is still a selected port.

主权项

1. A hardware control unit comprising:
a detection unit to receive detected conditions of data traffic across a link aggregation formed of a plurality of data links, wherein each data link of the plurality of data links is connected to a corresponding data port such that the data traffic across the link aggregation is distributed across the plurality of data links by the corresponding plurality of data ports, wherein a backup data port is assigned to each data port of said corresponding plurality of data ports, each said backup data port being a data port selected from the corresponding plurality of data ports other than the data port to be assigned a backup port; a selection unit to select a backup data port upon detection that a data port originally scheduled to forward data is connected to a data link that is not capable of data traffic; and a forwarding unit to cause diversion of the data originally scheduled for forwarding by the scheduled data port to be forwarded by the selected backup data port assigned to the scheduled data port.
