Embodiment Construction

[0037] The core idea of ​​the present invention is: configure the flow control strategy based on the application type in the device, the device automatically recognizes the application type of the flow, and forwards the flow according to the application type of the flow and the configured flow control strategy.

[0038] The present invention provides a flow control method, which is applied to a device that forwards traffic according to the application type of the traffic. The device is pre-configured with a routing control strategy for forwarding based on the application type of the traffic, such as figure 2 As shown, the method includes:

[0039] Step 201, the device acquires the received traffic, identifies the application type of the traffic, and searches for a matching routing control policy based on the traffic application type according to the application type of the traffic;

[0040] Step 202, if a routing control policy corresponding to the traffic application type is...

Abstract

The invention discloses a method and equipment for controlling flow. The method comprises the following steps that: the equipment receives flow and identifies the application type of the flow, and searches pre-configured routing control strategy according to the application type of the flow; if the routing control strategy corresponding to the application type of the flow is configured in the equipment configuration, the equipment transmits the flow according to the routing control strategy; and if the routing control strategy corresponding to the application type of the flow is not configured in the equipment configuration, the equipment searches a saved local routing table to transmit the flow. In the method, the flow control strategy based on the application type is configured in the routing equipment, and the routing equipment acquires the application type of the received the application type of the flow and forwards the flow according to the configured flow control strategy, so that load balance can be realized and key service can be ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a flow control method and equipment. Background technique [0002] With the popularization of industry wide area network construction and application, the business volume and business types carried on the wide area network are also increasing, such as ERP (Enterprise Resource Planning, enterprise resource planning system), video conferencing, VOIP (Voice Over Internet Protocol, Internet telephony) , e-mail business, etc. Due to the limited bandwidth of the WAN link and the long transmission distance, it is necessary to use a simple and effective traffic engineering method to control the transmission of these service flows on the WAN, reasonably plan network resources to ensure key services, and improve the utilization of network resources. Avoid congestion. [0003] For example, in figure 1 In the shown network, R1, R2, and R3 are original WAN interconnection devices, and the...
