Problems solved by technology

like Figure 1b As shown, in the case of cross-frame aggregation, due to the inconsistency of the incoming traffic of each frame (device), the local forwarding policy makes the traffic unable to evenly share the load among the service forwarding ports of each frame

Embodiment Construction

[0033] In view of the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a traffic sharing solution applied to a distributed system (ie, a network device using virtualization technology) to realize the Even load sharing between service forwarding ports of the device.

[0034] A traffic sharing method provided by an embodiment of the present invention is applied to traffic sharing of equal-cost forwarding paths in a distributed system. The distributed system has a control device, and network devices other than the control device are non-control devices. The following functions are added to the control device: the function of performing traffic statistics on each service forwarding port in the distributed system, and the function of triggering the load sharing of network devices whose actual total traffic is greater than the total traffic that should be allocated. The non-control device has added the function of reporting the tra...

Abstract

The present invention discloses a data flow sharing method and equipment. The data flow sharing method is applied for sharing data flow of an equivalent forwarding path of a distributed system. Network equipment is connected with one another through interconnection ports among the equipment. The data flow sharing method comprises the following steps: receiving a counted value of service forwarding port data flow reported by non-control equipment on the equivalent forwarding path by the control equipment in the distributed system, and in combination with the counted value of the service forwarding port on a same equivalent forwarding path, respectively calculating actual total data flow and to-be-allocated total data flow of each network equipment; comparing the actual total data flow and to-be-allocated total data flow of each network equipment by the control equipment, if a fact that the actual total data flow of the network equipment is larger than the to-be-allocated total data flow is found, using the network equipment as shunted equipment, selecting target network equipment for the shunted equipment, and triggering the shunted equipment to forward corresponding data flow to the target network equipment through the interconnection ports between the shunted equipment and the target network equipment according to a difference between the actual total data flow of the shunted equipment and the to-be-allocated data flow.

Description

technical field [0001] The present invention relates to network equipment virtualization technology in the field of communication technology, in particular to a flow sharing method and equipment. Background technique [0002] The current network device virtualization technology is developing extremely rapidly. Through network device virtualization technology, multiple switches can be interconnected to form a distributed switching architecture and run as a logical switching entity. From the perspective of management and configuration, a distributed switching architecture can be regarded as a switching device; from the perspective of performance, each switch in the distributed switching architecture can target the second layer or third layer traffic on its port Communication services make local forwarding decisions. Currently, typical network virtualization technologies in the industry mainly include IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) and V...
