Problems solved by technology

The first-level network flow control equipment connected in series between the routers needs to forward and schedule the traffic transmitted between the routers. When the traffic bursts in the network and the link traffic reaches or exceeds the given threshold, it may occur during operation. Various problems will cause some trusted traffic to be lost and the connection to be interrupted

Embodiment Construction

[0012] An intelligent link forwarding method, comprising the steps of:

[0013] (1) Initialize the network flow control device, including two links: 0 link and 1 link; the direction of traffic can be 0 link in, 0 link out, or 0 link in 1 link out; The traffic of link 1 also includes two directions; the trusted and untrusted traffic contained in the link, no matter which port the traffic enters from, will be load-balanced to the exit port of link 0 and 1;

[0014] (2) Under the condition of load balancing during the traffic peak period, if the two links have reached the set threshold, the link forwarding mechanism is logically triggered, and the hash algorithm is used to check the IP and The rule hit statistics are encrypted; whenever the quintuple rule of the request message matches the quintuple rule on the network flow control device, the traffic entering the 0 and 1 link ports will flow out from the 1 link exit, and all other Traffic flows out through the egress of link 0....

Abstract

The invention discloses an intelligent link forwarding method, which comprises the following steps of enabling :network flow control equipment to calculate the flow in real time to balance the flow entering from any port to a link outlet end in a load manner in a flow low peak period; in a traffic peak period, if the traffic size pps calculated in the network traffic control equipment exceeds a set threshold value, automatically changing a scheduling algorithm into selective scheduling, analyzing each incoming request message by the network traffic control equipment, acquiring source and destination IP values of the message, performing hash calculation, and matching the source and destination IP values with an encrypted rule; if the hash values of the source IP and the destination IP of the message are matched, forwarding the part of flow to a trusted link exit; and if the source IP and the destination IP of the message are not in the dictionary or cannot be correctly matched, forwarding the message to other link outlet ends. According to the invention, the trusted traffic can be intelligently switched to the idle trusted link for forwarding, so that reliable and stable forwardingof the trusted traffic is ensured.

Description

technical field [0001] The invention relates to the technical field of Internet management, in particular to an intelligent link forwarding method. Background technique [0002] In recent years, with the rapid development of the Internet, the real-time network security of massive data in the backbone network is particularly important. The first-level network flow control equipment connected in series between the routers needs to forward and schedule the traffic transmitted between the routers. When the traffic bursts in the network and the link traffic reaches or exceeds the given threshold, it may occur during operation. Various problems will cause some trusted traffic to be lost and the connection to be interrupted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent link forwarding method, which can intelligently switch trusted traffic to an idle trusted link for forwarding, so as to ensure reliabl...
