Embodiment Construction

[0018] Below in conjunction with Fig. 1, the implementation of the method of the present invention is introduced as an embodiment, the port service classification rate control method of the present invention comprises the following steps:

[0019] First, in step 10, a port configuration table is set on the user side port. For the RPR user-side port, you can specify the service type source sc_source of the port data service by setting the configuration table of a certain port, the receiving end A, B, and C type limit rate of the port (Ingress_rate_A, Ingress_rate_B, Ingress_rate_C), the sending end A, Type B and C limit rate (Egress_rate_A, Egress_rate_B, Egress_rat_C), port default VID and port default service type Port_sc, as shown in Table 1 below:

Abstract

The port rate controlling method based on service classification includes the following steps: to set port configuration list in the user side port; to read the port configuration list to obtain the service type source; to search different configuration lists based on the source to obtain the data relevant service type; to obtain limiting rate of the port corresponding service type based on rate control configuration; and to control the receiving and emitting rate based on different service type for the Ethernet frames of different service type. The present invention sets different service types for different user's requirement and controls the port receiving and emitting rate for the datan of different services to provide different service guarantee, strengthen the RPR space multiplexing characteristic, raise network service quality, reduce the equipment load and make the network service personalized and diversified.

Description

technical field [0001] The invention relates to a port rate control method, in particular to a data transmission flow control method in the communication field. Background technique [0002] In recent years, with the rapid development of data exchange and transmission technology, users' demand for communication network services tends to be more and more diversified, personalized and service immediacy, which undoubtedly affects the quality of service (QoS) of the network. put forward higher requirements. Make better use of network bandwidth, save operators' management costs, provide users with differentiated new value-added services, earn profits for operators, and improve the efficiency of switching and transmission equipment. These are what operators and equipment developers should consider question. [0003] As one of the means to improve QoS, port rate control is generally based on the port control mode or does not control the receiving and sending of ports, so that all...
