Second step: after mapping and Flow Control module 202 were received the data that the IB interface module sends, the state current according to the VL reception buffer added corresponding flow-control information at the IB packet, again these data sent to data processing module 203.
The 3rd step: data processing module 203 receives the packet that comprises flow-control information, payload with its HDLC Frame that can transmit as optical-fiber network, be encapsulated in the HDLC Frame, finish data framing, verification and evaluation work, then these data are sent to the SDH port by SDH interface module 204.
It is as follows that it receives flow process:
The first step: SDH interface module 204 receives data and sends to data processing module 203 from the SDH port.
Second step: data processing module 203 removes FLAG, Address, the headers such as Control, Protocol of HDLC with the data that receive, check verification and and will handle after data send to and shine upon and Flow Control module 202.
The 3rd step: the flow-control information of 6 bytes during mapping and Flow Control module 202 are taken out from data, the packet that removes flow-control information is sent to IB interface module 201, to give the state RXBS of the VL reception buffer of mapping and Flow Control module 202 simultaneously according to 2013 loopbacks of VL transmission buffer, realize Flow Control based on VL.
The 4th step: IB interface module 201 is according to the VL difference of the data of receiving, data are put into VL receive the corresponding position of buffer memory VL formation, the scheduling mechanism that sends according to administration module 205, for example adopt Weight Round Robin mode (WRR) between VL, the data in the VL buffer queue are outputed to the IB port by IB interface circuit 2011 by VL MUX.
This shows that the transmission equipment and the transmission method of the InfiniBand communication protocol based on optical-fiber network of the present invention utilize widely used SDH/SONET network, have realized the reliable transmission of IB in wide scope.With respect to prior art, the present invention has well solved the problem of IB long-distance transmissions, can realize the function such as server remote cluster, remote storage based on IB, has expanded the range of application of IB greatly.
