Abstract
The invention discloses a convergence method for unidirectional and bidirectional networks in bidirectional networks. The method comprises a bidirectional network A, a bidirectional network B, a port processing module C and a port processing module D. The bidirectional network A is connected with the port processing module C. The port processing module C is connected with the port processing module D through a unidirectional network. The port processing module D is connected with the bidirectional network B. Compared with the prior art, the method has the advantages that the network construction cost can be reduced, the unidirectional and bidirectional networks can interconnect and intercommunicate, moreover, and any end to end transparent transmission between multiple unidirectional and bidirectional networks can be realized. The invention provides a network architecture and protocol processing mode. According to the mode, when bidirectional signal transmission is unnecessary, effective communication still can be realized when there is a unidirectional transmission link.
Description
Technical field
The present invention relates to a kind of signal processing scheme, particularly relate to a kind of for the fusion method of single-direction and dual-direction network in bilateral network.
Background technology
Now a lot of equipment are required for first use two-way handshake agreement, shake hands and just start after successfully to transmit signal.But in a lot of transmission systems, the equipment place at two ends of shaking hands is remote two positions geographically, in order to set up communication, it is necessary to have two-way link, effective communication could be set up.But in a lot of demands, the transmission of information biases toward certain direction so that the link of other direction is in idle condition many times.
In existing system, when the node in bilateral network A to communicate with the node in bilateral network B, node in bilateral network A initiates communication request, initiation process is found receiving node, the request initiating communication of receiving node response sending node, owing to bilateral network A and bilateral network B is not joined directly together, therefore when the node in bilateral network A needs to the node-node transmission signal in bilateral network B, node in bilateral network B needs again to the node-node transmission response signal of bilateral network A, a bilateral network is then used to communicate between network A and network B.
Summary of the invention
The purpose of the present invention is that provides a kind of for the fusion method of single-direction and dual-direction network in bilateral network to solve the problems referred to above.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes bilateral network A, bilateral network B, port processing module C and port processing module D, described bilateral network A is connected with described port processing module C, described port processing module C is connected with port processing module D by unilateral network, and described port processing module D is connected with described bilateral network B；
Described port processing module C successively through storage assembly, send signal by unilateral network after receiving the node signal in bilateral network A after receiving signal extraction receiving node, judging whether the node being can communicate after unilateral network, and simulation receiving node transmits to bilateral network A after producing reception response signal simultaneously；
Described port processing module D receives and sends after buffer memory after the signal of unilateral network to signal emission module, signal transmitting module sends the signal to bilateral network B, bilateral network B feedback signal is to port processing module D, and port processing module controls sending module is controlled according to the response signal received.
The beneficial effects of the present invention is:
The present invention is a kind of for the fusion method of single-direction and dual-direction network in bilateral network, compared with prior art, the present invention can reduce the construction cost of network, it is possible to makes interconnecting of unidirectional and bilateral network, can realize between multiple unidirectional and two-way sub-network transparent transmission arbitrarily end to end simultaneously.The present invention proposes a kind of network architecture and protocol processes mode so that also can effectively communicate simply by the presence of unidirectional transmission link when some transmits without two-way signaling.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention includes bilateral network A, bilateral network B, port processing module C and port processing module D, described bilateral network A is connected with described port processing module C, described port processing module C is connected with port processing module D by unilateral network, and described port processing module D is connected with described bilateral network B；When node in bilateral network A initiates communication, port processing module C receives the signal of bilateral network A interior joint, and the signal received is transferred out by unilateral network, and simulation receiving node sends response signal to the node in bilateral network A simultaneously；When port processing module D receives the signal that unilateral network comes, the signal that port processing module D sends over unilateral network is sent to bilateral network B, receives the signal that bilateral network B interior joint sends over simultaneously.
As shown in Figure 2: described port processing module C after receiving the node signal in bilateral network A successively through storage assembly, receive signal extraction receiving node, judge whether the node being can communicate after unilateral network after send signal by unilateral network, simulation receiving node transmits to bilateral network A after producing reception response signal simultaneously；First port processing module C receives the signal from network A, by resolving the destination address information extracted in signal, then contrast with the address (this address is according to the address in the B network being connected with port processing module D and according to whether allows to be set by this unilateral network) being preset in this module, if this address is in preset address, then the mode by pushing is sent to port processing module D the signal from network A, and the response signal needed for simultaneously producing network A interior joint according to network protocol standard is sent to network A.
As shown in Figure 3: described port processing module D receives and sends after buffer memory after the signal of unilateral network to signal emission module, signal transmitting module sends the signal to bilateral network B, and bilateral network B feedback signal feeds back to signal transmitting module after receiving response signal module.Port processing module D receives the signal from unilateral network, when receiving after a complete packet or in reception buffer memory, number of signals exceedes certain capacity, port processing module starts to send signal to bilateral network B, receive the response signal from bilateral network B (if there is response signal) simultaneously, according to response signal and receive data volume in buffer memory number, send a signal to bilateral network B successively.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
