Description
Technical field
Present document relates to but be not limited to packet data exchanged technology, espespecially a kind of method for realizing data transmission and processing and dress
It sets.
Background technique
Exchange system is the key components of packet switching equipment, it is by exchange access device and exchange network group
At；Exchange access device includes source exchange access device and purpose exchange access device.Switching network is single by each exchange again
Member is connected with each other composition.It is exchanged between access device and crosspoint in source, between crosspoint and crosspoint, Yi Jijiao
It changes between unit and purpose exchange access device and is attached by serial high-speed link.
The asymmetric of switching network refers to: between two adjacent ranks of exchange network, there is a situation where that bandwidth is inconsistent,
It is i.e. inconsistent to all node link bandwidth of another rank in the node of any one rank.Fig. 1 is non-in the related technology
The network structure block diagram of symmetrical single stage switching network, as shown in Figure 1, switching network is in the topology that initial setting up Time Bandwidth is physical symmetry
Structure；When link down occurs in symmetrical topological structure, there is asymmetrical network structure；Such as when center line in Fig. 1
1 (SF_1#) of card has a link to disconnect and (indicating by the X of chain road) with exchanging for destination between access device 0 (SA_0#)
When, access device SA_0# is exchanged for purpose, exchange network occurs asymmetric, and the input tape of SF_1# is wider than output at this time
Bandwidth.Due to asymmetrical network structure, there may be local congestions by SF_1#, to influence whole net flow；In order to avoid right
The influence of whole net flow needs to carry out asymmetric processing to SF_1#；The relevant technologies generally close an input link of SF_1#
It closes；I.e. at least upstream chip retain a link arrive this chip under the premise of, guarantee upstream chip to this chip source
The ingress bandwidth for exchanging access device arrives the outlet bandwidth that purpose exchanges the purpose SA of access device no more than this chip, to have
Effect solves chip-scale congestion problems caused by asymmetric topology；Fig. 2 is to realize asymmetric place to single-stage switching network in the related technology
The network topology schematic diagram of reason, as shown in Fig. 2, due to link disconnection between SF_1# and SA_0#, after carrying out asymmetric processing:
Link between SA_4# and SF_1# is disconnected；Link between SA_6# and SF_1# is disconnected；Between SF_1# and SA_2#
Link is disconnected.
Line card refers to the asymmetric of line card: the exchange access device in business line card is inherently in asymmetrical state,
Due to the asymmetric processing of switching network, occur local congestion and switching traffic decline between two adjacent line cards of switching card.
Fig. 3 is line card in the related technology to the structural schematic diagram of the single-stage transmission network of line card, as shown in figure 3, transmission of the line card to line card
Network is made of three pieces of line cards, wherein includes business line card 1, business line card 2 and center line card 3 in network, on business line card 1
Source exchange access device issue cell, by center line card 3 crosspoint exchange reach service line card 2 on each mesh
Exchange access device.Fig. 4 is that line card is to the asymmetric single stage network structural schematic diagram of line card in the related technology, as shown in figure 4, industry
Film source exchange access device SA_2# has been inserted on business line card 1, and two panels purpose exchange access device SA_0# has been inserted on business line card 2
And SA_1#, the bandwidth that outputs and inputs on two pieces of business line cards and center line card are consistent.Assuming that SA_2# has 1 part of flow number
According to needing to be sent to SA_0#, there is 1 part of data on flows to need to be sent to SA_1#；According to the principle analysis of the relevant technologies, purpose is handed over
Change access device SA_0#, SA_1# exchanged with source access device SA_2# composition switching network be it is asymmetrical, using the relevant technologies
Asymmetric methods when being handled, a link between SA_0# and SF_0# will be simultaneously closed off；But to business line card 1 and
Speech, the data on flows that business line card 1 gives center line card 3 is 2 parts, and the data traffic that center line card 3 reaches business line card 2 is also
2 parts, if closing a link, an other link congestion is instead resulted in, the network transmission speed of switching network is reduced.
To sum up, the relevant technologies in data traffic in line card in the transmission process between line card, carry out asymmetric processing and drop
The low network transmission speed of switching network, wastes network bandwidth resources.
