[0007] The purpose of the present invention is to address the shortcomings of uneven business distribution of single boards in the prior art, and propose a method for balanced business distribution on a single board, so that each single board can evenly bear the business, and when the load of each single board is balanced When it is broken, it can restore the equilibrium state as quickly as possible

Embodiment Construction
[0026] The method for balanced service distribution on a single board proposed by the present invention first divides each physical single board on a network device into multiple virtual single boards, such as figure 1 shown, and then allocate a virtual board on each physical board to the same user; record the resource occupancy rates of all virtual boards belonging to the user, and sort them according to the resource occupancy; The virtual single boards with a rate less than the set value form a new set; allocate services to the virtual single boards in the new set in a polling manner; record the change of the resource occupancy rate of the virtual single boards in real time, and update the resources of the virtual single boards regularly Occupancy, reordered according to resource occupancy.
[0027] The network device in the above method is any one of high-end routers, gateways or switches.
[0028] In the above method, the process of forming a new set of virtual boards who...

Each physical single board in network device is divided into multiple virtual single boards. A virtual single board in each physical single board is allotted to same user. Resource occupancy rate in all virtual single boards belonged to the user is recorded. Resource occupancy rates are sorted. Virtual single boards with their resource occupancy rates less than a setting value constitute a new set. Operations are allotted to virtual single boards as well as single boards in new set by using pulling mode. Changes of resource occupancy rates of single board are recorded in real time. After resource occupancy rate being periodic updated, sorting is restarted. In the invention, operations are allotted to single board with smaller resource occupancy rate in higher priorit in order to ensure equilibrium distribution. When a new single board is started up or released, balance of resource occupancy rates is broken. In the invention, balance state is converged quickly.
Description
technical field [0001] The invention relates to a method for balanced service distribution on a single board, which belongs to the technical field of data communication. Background technique [0002] In large-scale communication equipment, due to the large amount of traffic, a large number of port resources and internal resources of the device are required, and multiple boards are often required to share the load. When distributing services, the problem of how to allocate services among multiple boards arises. For example, in the case that there are multiple single boards that can provide IP port resources, how to distribute IP services to these single boards in a balanced manner according to the resource occupancy rate of each single board. For this reason, an algorithm that distributes services in a balanced manner among several boards is needed. [0003] There are two commonly used distribution methods: [0004] One is to allocate services to the boards one by one in a ...
