Embodiment Construction

[0010] By decomposing the traffic into a finer-grained manner according to the processing capacity of the processor, the maximum number of traffic granularities that can be accommodated on each processor will not cause the target processor to be overloaded, and then each granularity is allocated to a MAC address; each target processing Machines are bound to the corresponding number of MAC addresses according to the allocated granularity, so as to realize the wire-speed distribution of traffic under non-uniform processing capacity. When the traffic of the backbone network increases, the line rate of the traffic to be distributed by the target processor will also increase.

[0011] For example, if the actual number of target processors is n, and the processing capacity of half of them is twice that of other processors, you can use 1.5n as the total number of processors for hash modulo when performing line-speed shunting, and then according to the processing capacity The machine ...

Abstract

The invention discloses a device and method of achieving line speed shunt of flow to be processed through binding multiple media access control (MAC) addresses by utilizing a monoprocessor, so that the flow can be distributed according to the practicable capability of the processor under the condition that the capability of the processor is uneven. The device carries out decomposition of fine grit on the flow according to the processing capability, so that the grit number of the flow contained in each processor is maximum and the overload of a target processor can not be caused; then the grit of each flow is distributed to an MAC address; and corresponding MAC address number is bonded by each target processor according to the distributed grit number, thereby achieving the line speed shunt of the flow under the uneven processing capability. If the difference of the processing capabilities of the processors in a system is large, the load rate of the processor with high processing capability is promoted by using the method, and the processor with low processing capability does not need to be accommodated, thus obviously improving the return on investment and enhancing the flexibility and adaptability of the system.

Description

[0001] This application is a divisional application of the invention patent application for "line-speed shunting equipment and method". [0002] The filing date of the original application is July 7, 2010, the application number is 201010219729.X, and the name of the invention is line-speed shunting equipment and method. technical field [0003] The patent of the present invention relates to a wire-speed distribution device and method in the field of information, in particular to a distribution device and method for special processing of backbone network traffic, which enables the use of ordinary low-speed data processing devices to meet high-speed online processing The capacity of the main flow can meet the problem of unbalanced processing capacity of the back-end processor. Background technique [0004] When processing backbone network traffic, in order to decompose the traffic into the range that can be handled by a single processor, use dedicated collection and filtering...
