Embodiment
Core concept of the present invention is: message forwarding equipment comprises multilink at up direction, and the up link that the message that message forwarding equipment receives from down direction passes through high priority sends, and the up link of low priority is by idle.When causing up packet loss owing to the flow of down direction is excessive, message forwarding equipment carries out the priority division to the flow of down direction, up link by high priority sends the message of high priority, sends the message of low priority by the up link of low priority.
For the clear method of introducing message forwarding provided by the invention, illustrate this method below by concrete application scenarios.As shown in Figure 3, being applied to non-blocking network with this method is example, and wherein message forwarding equipment is access-layer switch S1.As shown in Figure 4, this method may further comprise the steps:
Wherein, S1 calculates link priority and mainly considers factors such as link bandwidth, link overhead, and among the present invention, the P1/P2 link is identical with the P3/P4 link bandwidth, and priority is identical, constitutes equal-cost route, and S1 uses P1/P2 link and P3/P4 link to carry out load balancing.
The P1/P2 aggregated links is as logical links, after its state be set be Standby, still can carry out transfer of data by physical link P1 link wherein, but because the P1 link bandwidth is lower than the P3/P4 link, priority is lower, at the P3/P4 link just often, S1 only uses P3/P4 link transmission message.
S1 is provided with port packet loss statistical function, detects the message packet loss of uplink port P3 and P4.When definite P3 and P4 packet loss, when perhaps detecting the message packet loss greater than threshold value, S1 determines the uplink bandwidth deficiency.S1 issues polymerization CAR (Committed Access Rate, agreement access rate) configuration speed limit on downlink port, stamp the flow mark of different stage for the flow that enters S1.Concrete, the message that the S1 downlink port receives enters the message process chip, and the message process chip disposes according to polymerization CAR the flow that enters in the particular port scope is added up, and is that flow is stamped the flow mark according to statistics.In the embodiment of the invention, polymerization CAR configuration requirement carries out the bandwidth speed limit to the flow that all downlink ports enter, be that the message process chip is added up the flow that all downlink ports receive, flow in the limiting bandwidth scope is stamped high priority flag, the extraneous flow of limiting bandwidth is stamped low-priority flags.
S1 is provided with the message forwarding strategy, and the message of the high priority up link by high priority is sent, and the message of the low priority up link by low priority is sent.In the embodiment of the invention, the P3/P4 link transmission DSCP by high priority is 7 message, and the P1 link transmission DSCP by low priority is 6 message.
