Description
Technical field
The present embodiments relate to field of communication technology more particularly to a kind of message forwarding methods and device.
Background technology
In field of communication technology, Ethernet switch is the interchanger based on Ethernet transmission data, Ethernet exchanging
Each port of machine is directly connected with host, and is generally all operated in full duplex mode.
Ethernet switch forwards the message according to the target MAC (Media Access Control) address of message received, as the purpose MAC of message
Not in the mac address table of interchanger, interchanger broadcasts the message in the LAN belonging to it for location, and only MAC Address is to be somebody's turn to do
The host of target MAC (Media Access Control) address can just respond this broadcast, after interchanger receives response, by the MAC Address of the host of response and
The port that interchanger receives the response is recorded in mac address table, i.e., interchanger by dynamic learning MAC Address with establishing MAC
Location table.
With the development of the communication technology, there is All-optical switching machine, the All-optical switching machine is big compared to Ethernet switch
Message forward efficiency is improved greatly, reason is that All-optical switching machine does not establish mac address table by dynamic learning MAC Address, and
It is the correspondence according to preset inbound port and exit port, the message that a certain inbound port receives is forwarded directly to this
The corresponding exit port of inbound port is sent the message by the exit port, since the cost of All-optical switching machine is handed over than Ethernet
The cost changed planes is high, if all Ethernet switches in existing communication network are replaced with All-optical switching machine, will cause to lead to
The cost of communication network greatly increases.

State the port numbers of the corresponding exit port of port numbers of receiving port；
The message to be forwarded is sent to the exit port by the port numbers according to the exit port.
The other side of the embodiment of the present invention is to provide a kind of apparatus for forwarding message, including：
Receiving module, the message to be forwarded that the receiving port for receiving Ethernet switch receives are described to be forwarded
Message includes the port numbers of the receiving port；
Exit port determining module is used for the port numbers of the port numbers and each exit port according to pre-set each receiving port
Correspondence, determine the port numbers of corresponding with the port numbers of receiving port exit port；
The message to be forwarded is sent to the exit port by forwarding module for the port numbers according to the exit port.
Message forwarding method and device provided in an embodiment of the present invention, by being added in the message that receiving port receives
The port numbers of receiving port, and according to the correspondence between the port numbers of receiving port and the port numbers of exit port, get
With the port numbers of the unique corresponding exit port of receiving port, and message is sent to exit port, i.e., by handing over existing Ethernet
Change planes carry out function module addition so that existing Ethernet switch can realize the function of All-optical switching machine, be not required to by
All Ethernet switches in existing communication network replace with All-optical switching machine, and the cost of communication network is greatly saved.

The structure chart of the applicable Ethernet switch of retransmission method.If the embodiment of the present invention be directed to by existing communication network it is all with
Too network switch replaces with All-optical switching machine, and the cost of communication network can be caused to greatly increase, provide message forwarding method, should
Method is as follows：
Step S101, the message to be forwarded that the receiving port of Ethernet switch receives, the message to be forwarded are received
Include the port numbers of the receiving port；
The embodiment of the present invention by increased on the basis of existing Ethernet switch structure shift control module 22,
Link detecting control module 24 and port configuration module 25, to realize the function of All-optical switching machine, such as Fig. 2, so, the present invention is real
It includes photoelectric conversion module 21, shift control module 22, electricity to apply the Ethernet switch that the message forwarding method that example provides is applicable in
Light conversion module 23, link detecting control module 24 and port configuration module 25, wherein photoelectric conversion module 21 and electro-optic conversion
Module 23 is the original module of existing Ethernet switch, and port A and port B are respectively two differences of Ethernet switch
Port, port A and port B can be used in sending message and receive message, and when port, A receives message, port A is receiving terminal
Mouthful, when port A sends message, port A is exit port, and similarly, when port B receives message, port B is receiving port, when
When port B sends message, port B is exit port.Therefore, the receiving port of Ethernet switch and exit port are relative to message
Reception with send and define.
In embodiments of the present invention, preferred port A is receiving port, and port B is exit port, after port A receives message
Message to be forwarded is obtained after adding the port numbers of port A in heading, message to be forwarded is sent to conversion and control mould by port A
Block 22.
Step S102, it is closed according to the port numbers of pre-set each receiving port are corresponding with the port numbers of each exit port
System determines the port numbers of exit port corresponding with the port numbers of the receiving port；
Preset rules are provided in advance in shift control module 22, which includes the port numbers of receiving port, with
And with the port numbers of the unique corresponding exit port of receiving port, for example, port A and port B is at unique corresponding relation, i.e. port A
All from port, B is sent out the message received, and preset rules include multiple correspondences such as port A and port B, conversion control
Molding block 22 is got and the port numbers of the unique corresponding port B of port A according to the port numbers of port A from preset rules.
Step S103, the message to be forwarded is sent to the exit port according to the port numbers of the exit port.
After shift control module 22 gets the port numbers of port B, the port numbers according to port B send message to be forwarded
To port B.
The embodiment of the present invention in the message that receiving port receives by adding the port numbers of receiving port, and according to connecing
