Transmit control module, be used for when receiving Flow Control message or separating Flow Control message, judging whether local node is the source node device, if, then to local forwarding queue setting forbid sending sign start simultaneously timer module and stop the forwarding of packet or remove local forwarding queue forbid that sending sign notice timer module stops timing and continue the forwarding data bag, otherwise, this Flow Control message or solution Flow Control message are continued to transmit according to forward-path;
Timer module is used for carrying out initialization and beginning timing when the forwarding control module forbids sending sign to local forwarding queue setting, and timing stops when removing local forwarding queue.
The method of the processing network congestion among the present invention, it may further comprise the steps:
A. the forwarding queue constructing module of each node device is constructed forwarding queue in this locality, and the packet that needs are transmitted is added in the forwarding queue;
B. the forwarding queue monitoring module of each node device is monitored the length of the current forwarding queue of this locality, when the forwarding queue monitoring module of certain node device judges that the length of current forwarding queue satisfies the Flow Control condition, then from the packet that enters forwarding queue, obtain the source information of data flow, and generate Flow Control message and send to the source node device, enter step c; After this, when the forwarding queue monitoring module of this node device judged that the length of current forwarding queue satisfies solution Flow Control condition, generating solution Flow Control message sent to the source node device, enters steps d;
C. the forwarding control module of arbitrary node device judges whether local node is the source node device when receiving Flow Control message, if then local forwarding queue setting is forbidden sending the forwarding that indicates and stop packet; Otherwise, this Flow Control message is continued to transmit according to forward-path;
D. the forwarding control module of arbitrary node device judges whether local node is the source node device when receiving solution Flow Control message, if the transmission of forbidding of then removing local forwarding queue indicates, continues the forwarding of packet; Otherwise, should separate Flow Control message and continue to transmit according to forward-path.
For ease of understanding the present invention for the processing method of network congestion, below in conjunction with accompanying drawing respectively from 1, the handling process of congested end node forwarding data bag; 2, the source node is conciliate the handling process of Flow Control message to Flow Control message; 3, the handling process of source node for data forwarding bag; 4, the several parts of timer expiry handling process are specifically addressed:
At first, each node is in order to transmit data stream, need to construct transmit queue in this locality, the operation that packet in the data flow is transmitted in fact namely packet enter formation operation and dequeue operation, under normal circumstances, entering the number of packet of formation operation and the number of carrying out the packet of dequeue operation in a period of time tends to balance, when yet forwarding channel only has one when there being a plurality of data flow to converge in some nodes, the number that the packet of formation operation can occur entering in a period of time is far longer than the number of the packet that carries out the dequeue operation, bottleneck effect appears in the forwarding channel of this node in other words, at this moment forwarding channel congested of this node will occur, this node is called congested end node; Congested end node generally all can appear on the node device that packet is about to flow out network (such as the node F among Fig. 1).
As shown in Figure 3, will carry out pathfinding according to the routing information in the packet when certain node receives packet processes, if need the packet of forwarding, then packet is added in the local forwarding queue and (namely enters the formation operation), by the forwarding queue monitoring module of this node the length of the current forwarding queue of this locality is monitored simultaneously, if the length of current forwarding queue satisfies Flow Control condition (as: length of current forwarding queue 〉=full queue length 80%), illustrate that then this node is congested node (such as the node F among Fig. 1), then from the packet that enters forwarding queue, extract the source information of data flow, generate Flow Control message and send to source node device (such as the node A among Fig. 1 and node D), the notification source end node devices stops to send packet, current forwarding queue enters the Flow Control state, under the Flow Control state, local forwarding queue is packet discard not, but continues packet is entered formation operation and dequeue operation; Along with the source node device stops to send packet, the queue length meeting of the packet in this forwarding queue reduces gradually, if the length of current forwarding queue satisfy to be separated Flow Control condition (as: length of current forwarding queue≤full queue length 20%), then generating solution Flow Control message sends to the source node device, current forwarding queue is removed the Flow Control state, still continues packet is entered formation operation and dequeue operation.
Send to the source node device in the process of Flow Control message or solution Flow Control message at congested end node, this Flow Control message or solution Flow Control message may be passed through a plurality of intermediate nodes, these intermediate nodes can be transmitted according to Flow Control message or the routing information of separating in the Flow Control message, until this Flow Control message or solution Flow Control message arrive the source node device.
As shown in Figure 4, when the source node device receives Flow Control message, local forwarding queue setting is forbidden sending sign, stop the forwarding of packet, and the startup timer carries out timing, because source node device (such as the node A among Fig. 1 and node D) stops the forwarding of packet, and data-source device (such as the host A among Fig. 1 and main frame D) is not known the forwarding that the source node device has stopped packet, still can continue to source node device transmitting apparatus, can cause like this forwarding queue length of source node device this locality more and more longer, the packet that namely enters forwarding queue is more and more, abandons follow-up packet until queue overflow occurs; After this, when the local forwarding queue length of congested end node satisfies when separating the Flow Control condition and sends to the source node device and to separate Flow Control message, the source node device is removed local forwarding queue after receiving this solution Flow Control message the transmission of forbidding indicates, continue the forwarding of packet, and stop the timing operation of timer.
Fig. 5 has illustrated the flow process of source node device forwarding data bag: the source node device carries out pathfinding according to the routing information in the packet when receiving packet processes, if need the packet of forwarding, to judge also whether local forwarding queue has and forbid sending sign, if no, then packet is entered the normal forwarding of formation operation; Forbid sending sign if having, although this moment, source node device itself did not occur congestedly, can not transmit, just enter the formation operation, abandon follow-up packet until local forwarding queue overflows.
Need to prove, the source node device is forbidden sending the sign except what can remove receiving the solution Flow Control message that congested end node sends local forwarding queue, if the timer timing is overtime, the transmission of forbidding that also can remove voluntarily local forwarding queue indicates, continue the forwarding of packet, its flow process as shown in Figure 6; This dual mode is combined with so that more flexible to the forwarding control of packet.
Owing to when carrying out congested processing, directly the packet loss action carried to source node device place, but not just packet loss of congested Nodes occured, can avoid like this invalid data to wrap in the transmission of nodes, thereby promote network utilization, conserve network resources.
