Abstract
A Software Defined Networking (SDN) controller selects ports from among ports on an SDN edge device as selected ports of an aggregation group according to an aggregation strategy.
Claims15
A link aggregation method, comprising:
- receiving, by a Software Defined Network (SDN) controller, Link Aggregation Control Protocol (LACP) packets belonging to a same aggregation group from a network device outside of an SDN via an SDN edge device;
- selecting, by the SDN controller, ports from among ports on the SDN edge device that have received LACP packets as selected ports of the aggregation group according to an aggregation strategy;
- informing the network device of the SDN edge device at which the selected ports are located, so as to cause the network device to negotiate with the SDN edge device to complete a link aggregation;
- wherein said informing comprises the SDN controller sending LACP packets to the network device.
1 more element
A link aggregation method, comprising:
- receiving, by an SDN edge device, LACP packets from a network device outside of an SDN and forwarding the LACP packets from the network device to an SDN controller;
- receiving, by the SDN edge device, LACP packets from the SDN controller, sending the LACP packets from the SDN controller to the network device and negotiating with the network device to complete link aggregation.
A device, comprising:
- a receiving unit, to receive Link Aggregation Control Protocol (LACP) packets belonging to a same aggregation group from a network device outside of an SDN via an SDN edge device;
- and
- a processing unit, to select a number of ports from among ports on the SDN edge device for receiving the LACP packets as selected ports of the aggregation group according to an aggregation strategy, and send LACP packets to inform the network device of an identify of the SDN edge device at which the selected ports are located, so as to cause the network device to negotiate with the SDN edge device to complete a link aggregation.
A device, comprising:
- a receiving unit, to receive Link Aggregation Control Protocol (LACP) packets from a network device outside of an Software Defined Network (SDN) and receive LACP packets from an SDN controller;
- a sending unit, to forward the LACP packets from the network device to the SDN controller;
- a processing unit, to forward the LACP packets from the SDN controller to the network device and negotiate with the network device to complete link aggregation.
