The datum plane of place, control point business board, for the protocol massages receiving from system in described protocol massages arranges priority; Concrete, the datum plane of place, different layers control point business board, for the protocol massages receiving from system arranges different priority; The level at control point is higher, and the datum plane of this place, control point business board is that the priority that arranges of the protocol massages that receives from system is higher.The protocol massages that the datum plane of each like this layer of place, control point business board can priority treatment respectively receives outward since system.
On the datum plane of place, control point business board is preferential by protocol massages high current pending protocol massages medium priority, deliver to the control plane of this place, control point business board.Concrete, in the time that current pending protocol massages quantity is not more than the first forwarding capacity threshold value, will on protocol massages, deliver to the control plane of this place, control point business board according to priority order from high to low.Be greater than the first forwarding capacity threshold value in current pending protocol massages quantity, but while being less than the second forwarding capacity threshold value, can forward the priority of protocol massages partly higher than the priority of the protocol massages of transfer part, and the protocol massages that can forward part is according to the control plane of delivering to this place, control point business board in priority order from high to low.In the time that current pending protocol massages quantity is greater than the second forwarding capacity threshold value, can forward the priority of protocol massages partly higher than the priority of the protocol massages of transfer part, the priority of the protocol massages of transfer part is higher than the priority that abandons protocol massages partly, and the protocol massages that can forward part is according to the control plane of delivering to this place, control point business board in priority order from high to low.
For instance, data communications equipment as shown in Figure 2 adopts two-layer distributed system architecture, and the superiors are a master control borad, and lower floor is made up of multiple business boards.And be set to control point 1 for a business board in a certain protocol massages lower floor, master control borad is set to control point 2.This data communications equipment adopts committed access rate (committed access rate, be called for short CAR) technology, provide protocol massages speed limit processing capacity by two token buckets, suppose that lower floor's business board is 12, convergence ratio is 50%, committed information rate (the committed information rate of each business board, be called for short CIR), the first forwarding capacity threshold value is 128Kb/s(bps), peak information rate (peak information rate, be called for short PIR), the second forwarding capacity threshold value is 128Kb/s × 12 × 50%-128Kb/s=640Kb/s.
On the business board at 1 place, control point, forwarding chip receives after protocol massages, first according to the first forwarding capacity threshold value and the second forwarding capacity threshold value that arrange, current pending protocol massages is dyeed.In this example, current pending protocol massages is all protocol massages that forwarding chip receives each second.
Concrete, the protocol massages quantity receiving when forwarding chip is per second is no more than 128Kb, and all protocol massages that receive are colored as green.
The protocol massages quantity receiving when forwarding chip is per second exceedes 128Kb, but do not exceed 640Kb, the protocol massages receiving per second forwarding chip is divided into two parts, the quantity of Part I protocol massages is 128Kb, be green by the dyeing of Part I protocol massages, remaining protocol massages is Part II protocol massages, and the quantity that is also Part II protocol massages is the poor of the forwarding chip protocol massages quantity receiving per second and 128Kb, is yellow by the dyeing of Part II protocol massages.
The protocol massages quantity receiving when forwarding chip is per second has exceeded 640Kb, the protocol massages receiving per second forwarding chip is divided into three parts, the quantity of Part I protocol massages is 128Kb, be green by the dyeing of Part I protocol massages, the quantity of Part II protocol massages is the poor of 640Kb and 128Kb, be 512Kb, be yellow by the dyeing of Part II protocol massages, remaining protocol massages, also the quantity that is Part III protocol massages is the poor of the forwarding chip protocol massages quantity receiving per second and 640Kb, be redness by the dyeing of Part III protocol massages.
After dyeing, forwarding chip is processed the CPU dyeing as delivering to control point 1 place business board on green protocol massages, dyeing is processed for the forwarding chip of delivering to control point 2 place business boards on yellow protocol massages, dyeing is abandoned for red protocol massages.
Can be found out by this example, prior art only arranges a control point in whole system, it is per second can retransmission protocol message capacity be only 128Kb, and utilize the embodiment of the present invention that distributed system and protocol message processing method are provided, it is per second forwards that to learn protocol massages capacity be 640Kb, above send the quantity of protocol massages to be significantly improved.And the quantity of business board is more, its can on the protocol massages quantity sent more.
