Embodiment Construction

[0028] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Flow control is to control the flow rate, more specifically, to control the flow rate of a user or an application. That is to distinguish between individuals and applications to regulate and control bandwidth.

[0030] The flow control is only related to the point-to-point traffic between the sender and the receiver, which is a local problem. Its job is to ensure that the sender cannot transmit data at a rate higher than the receiver can handle. Flow control is a mechanism to prevent network congestion.

[0031] Such as figure 1 As shown, the present invention discloses an embodiment of a power system network bandwidth and flow control method, which realizes the allocation of different bandwidths for different applications. At the same time, in order to ensure important services (such as ERP, VOIP calls, video conferencing, VPN), We a...

Abstract

The invention discloses a power system network bandwidth and flow control method, including: 1. A bandwidth control device groups user terminals into: fixed reserved groups, dynamic reserved groups, and ordinary groups; 3. Identify the user terminal sending data, and determine the group to which the user terminal sending data belongs; 4. Allocate a fixed value of bandwidth to the user terminal of the fixed reserved group; 5. Dynamic reserved group The user terminal is allocated the maximum bandwidth for data transmission, and if not, the minimum bandwidth is allocated; 6. The remaining bandwidth after the fixed reservation group and the dynamic reservation group are occupied is allocated to the user terminal of the ordinary group. The present invention can guarantee the core business through the setting control of the flow control device, effectively manage the online behavior of each user in the network, improve the work efficiency of the internal staff, improve the bandwidth usage efficiency of the external network link of the network, and reduce the Investment cost of egress bandwidth.

Description

technical field [0001] The invention relates to an information communication network optimization method of a power system, in particular to a method for controlling network bandwidth and flow of a power system. Background technique [0002] With the increasing popularity of extranets, the demands of intranet users to access extranets are increasing, and some enterprises also need to provide external services such as WWW page browsing, FTP file transfer, DNS domain name resolution, etc. These factors will lead to a sharp increase in network traffic Things like live streaming, VoIP, and cloud applications are overwhelming corporate bandwidth and making everyone sluggish. [0003] On a traditional IP network, all packets are treated equally without distinction. Each router adopts a first-in-first-out (FIFO, First In First Out) strategy for all packets, and it does its best (Best-Effort) to send the packets to the destination, but the reliability of packet transmission is limi...
