Problems solved by technology

[0008] 2. Very sensitive to network delay
[0021] Configure static IP / port number identification features through ACL, which is vulnerable to attacks
Fixed IP addresses and port numbers are easy to forge
When a router configured with ACL receives a forged small packet attack, it is easy to be paralyzed or the attack traffic occupies all bandwidth resources.

Embodiment Construction

[0066] As described in the background, the existing ACLs have shortcomings in identifying small packet data flows, mainly because ISP routers cannot define the IP and port number characteristics of small packet data flows and are vulnerable to attacks.

[0067] This law describes a technology based on small packet data flow session management to intelligently identify small packet data flow and realize the requirement of small packet priority scheduling, and can intelligently identify small packet data on routers in the entire network flow while avoiding attacks. Based on such a technical idea, priority scheduling can also be performed for other types of specified TCP data streams.

[0068] Based on the above ideas, the present invention provides a scheduling method for TCP data streams, which is applied to a network system including at least one terminal device, a router, and at least one server. The packets in the transmitted TCP data stream are divided into multiple types....

Abstract

The invention discloses a method and a device for dispatching TCP data stream, which can intelligently identify small-sized message data stream based on the technology of session management of the small-sized message data stream, meet the priority dispatching requirement of small-sized message, can intelligently identify the small-sized message data stream on a full-network router, simultaneously avoid being attacked, and further carry out priority dispatching for random specific message type according to the technical ideas of the invention.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for scheduling TCP data streams. Background technique [0002] With the rapid development of the Internet industry, many network operators and Internet companies regard the data center as another economic growth point of the Internet industry after many tests by ISP and ICP. [0003] The global economic crisis has spread to many industries, but the Internet industry has grown against the trend. According to the latest data from iResearch, the growth rate of the Internet industry exceeded 50% last year, and the growth rate of GDP exceeded 10%. In the context of the economic crisis, the Internet industry can continue to maintain a good growth momentum and become the main force leading IDC out of the trough. [0004] Now the Internet is ushering in unprecedented development opportunities. China already has nearly 300 million Internet users, which provides...
