A method and device for improving data forwarding performance of WAN bridge

Abstract

The invention discloses a method and a device for improving the performance of data forwarding of the WAN Bridge. The invention comprises the processes that the corresponding address learning items are set in a forwarding table after the WAN bridge receives the data packets; when the WAN bridge forwards the data packets, the WAN bridge first judges the type of the data packets; if the data packets are uni-packets, the WAN bridge determines the forwarding path of the data packets to be sent by querying the address learning items in the forwarding table so as to further forward the data packets according to the forwarding path. Compared with the prior art, the data forwarding mechanism of the invention effectively improves the performance of data forwarding of the WAN bridge with a simpler principle for operation and an easier method for implementation. With respect to the processing of the data packets, the invention realizes the transition from forwarding all data packets blindingly to all link accesses in the prior art to precise forwarding via the forwarding path of data packets determined by the invention, and particularly shows obvious improvement in data forwarding performance of the WAN bridge when a large number of the shared-links exist.

Description

technical field [0001] The invention relates to WAN (wide area network, wide area network) side access of a home gateway device, in particular to a method and device for effectively improving the data forwarding performance of a WAN bridge. Background technique [0002] At present, more and more abundant network application services are integrated on the gateway device. In addition to providing basic Internet access services for users, it also provides services such as network video, VoIP, and video surveillance, and also provides support for operators' network management. Such a variety of network services need to be based on different types of WAN connections. Business applications lead to diversification, sharing, and combination of requirements for WAN connections on gateway devices, and can no longer be a single bridging application or routing application. At the same time, taking into account the two levels of technology and resources, how to support multiple shared ...

Problems solved by technology

[0004] Although the inherent wan bridge technology basically solves the need for wan interface sharing, there are two main problems. One is the low performance of data forwarding. When the wan bridge receives and processes data packets from the wan side, it cannot accurately judge the data packets. The precise forwarding path, but blindly adopts the way of forwarding to all connection paths, there must be unnecessary data forwarding, from the perspective of creating data packets, there is a huge waste, and it will bring inconvenience to the subsequent links to process data packets Necessary load; the second is the existing data distribution mechanism, which does not judge and distinguish routing connections and bridging connections during distribution, which will inevitably cause crosstalk between data packets between different connection paths. In specific application scenarios, due to other connections The data packet interference of the channel will seriously affect the business application of the connection channel, and sometimes the business cannot even be carried out normally
