Description
Technical field
The present invention relates to the communication technology, especially a kind of duplexing pattern matching method and device, communication system.
Background technology
Ethernet is that (Institute of Electrical andElectronics Engineers is hereinafter to be referred as IEEE) standardized a kind of local area network (LAN) interconnection technique by U.S. electric and Electronic Engineering Association.At present, the Ethernet of mainstream applications connect media mainly be optical fiber and unshielded twisted pair (UnshieldedTwisted Paired, hereinafter to be referred as: UTP) two kinds.Wherein, because optical fiber and laser transceiver cost an arm and a leg, realize that the cost of optical fiber connection is very high, therefore, optical fiber connects the connection that is mainly used in the garden backbone network.Comparatively speaking, UTP is cheap, and easy for installation, therefore, connects (that is: data terminal equipment such as personal computer or data server is linked into the connection of the network switch) field at the desktop to cost sensitivity and has obtained using comparatively widely.
According to IEEE 802.3 standards, auto-negotiation (AutoNegotiation) is arranged, force full duplex (Full Duplex) and force three kinds of mode of operations of half-duplex (HalfDuplex) as the Ethernet of transmission medium with UTP.The full duplex mode of operation is meant, also can receive data when sending data, sends data and carries out with the reception data sync.The half-duplex mode of operation is meant, only allows in the time period to send data or receive data.The ethernet port of semiduplex mode is followed Carrier Sense Multiple Access (the Carrier Sense Multiple Access with Collision Detection of band collision detection, hereinafter to be referred as: CSMA/CD) mechanism, before each data send, detect interconnection the other side earlier and whether sending data, also promptly: whether the port is receiving data, does not only send the other side just to begin to send data under the data conditions.If the port in the process that sends data, finds that interconnection the other side begins to send data suddenly, know that conflict appears in interconnection both sides' data transmit-receive, then the port stops to send data immediately, attempts sending data after waiting for a period of time again again.Sent half and the packet that is stopped transmission is commonly referred to as the crumb data bag at the port.According to CSMA/CD mechanism, conflict must be detected in beginning to send preceding 64 byte times of data, and detected conflict is called as slow conflict (Late Collision) after 64 byte times.It is normal the network of conflict explanation late malunion to occur.
When two ethernet ports of interconnection all are operated in auto negotiation mode following time, the interconnection both sides send interconnection the other side with own to according to keeper's mode of operation information that be provided with, that can support, and receive interconnection the other side passes over, its mode of operation information that can support, according to the algorithm among mode prioritization level and the IEEE802.3, the interconnection both sides are configured to the mode of operation of the peak performance that both sides' port all supports automatically, to guarantee the unanimity of both sides' port working pattern.Because the dual-mode of interconnection both sides port is both sides' a negotiation result, therefore, the interconnection both sides are operated under the identical dual-mode, and both sides' mode of operation is bound to duplexing the coupling.In this case, network connects normal, and data communication is no problem.
When having a port not to be operated in auto-negotiation mode, the interconnection both sides do not transmit own mode of operation information to interconnection the other side port mutually in two ethernet ports of interconnection, but according to working under the mode of operation that oneself is provided with by the keeper.When the port that is set to the auto-negotiation mode of operation and being set to forces the port of diplex operation pattern to connect, no matter what be in the port setting of forcing diplex operation pattern one side is to force the half-duplex mode of operation or force the full duplex mode of operation, because the port that is operated under the auto-negotiation mode of operation is not received the mode of operation information that the other side's port sends, regulation according to the IEEE802.3 standard, be operated in port under the auto-negotiation mode of operation and can start parallel detection (ParallelDetect) function and come to connect, oneself mode of operation is configured to force the half-duplex mode of operation with interconnection the other side port.At this moment, if interconnection the other side is configured to force the full duplex mode of operation, port that interconnection the other side just occurred forces the diplex operation pattern (hereinafter to be referred as unmatched situation dual-mode).
Two port workings that no matter interconnect influence network quality forcing as long as the unmatched situation of dual-mode occurred, serious packet loss phenomenon all can to occur under duplex or the auto-negotiation mode of operation, destroy stability of data transmission.Its reason is to be operated in the CSMA/CD mechanism that the port of forcing under the half-duplex mode of operation is followed Ethernet, do not consider this point and be operated in the other side's port of forcing under the full duplex mode of operation, before sending packet, can not monitor network state, this just makes that being operated in the port of forcing under the full duplex mode of operation when being operated in the port of forcing under the half-duplex mode of operation sends packet through being everlasting sends the action breaks of data, thereby causes packet loss.
In the prior art,, two kinds of solutions have been proposed at the unmatched problem of ethernet port dual-mode.First kind of solution is: transmit interconnection both sides' duplex mode information by two pairs of idle among UTP lines, the coupling of the both sides' dual-mode that guarantees to interconnect.There is following problem at least in this scheme: needs are changed the connected mode of Ethernet interface physical connection line, and the interface after connected mode changes is not followed the IEEE802.3 standard, make this port can not with the ethernet device compatible interconnect of other manufacturer.
Second kind of solution is: the conflict and cyclic redundancy check (the CyclicalRedundancy Check that occur on the monitoring the port, hereinafter to be referred as: mistake bag quantity CRC), if the conflict and the wrong bag of the CRC quantity that monitor on the port have surpassed predefined numerical value in the regular hour, think that then the dual-mode of interconnection both sides port does not match, the pressure half-duplex mode of operation of the port work is switched to force the full duplex mode of operation.Though this scheme does not need to change the connected mode of Ethernet interface physical connection line, but there is following problem at least: comparatively subjective in this scheme to the unmatched basis for estimation of duplex, all be operated at interconnection both sides port and force half-duplex mode of operation following time, if it is very busy that network data is transmitted, the wrong bag of a large amount of conflicts and CRC just may appear on port, if think that at this point interconnection both sides dual-mode does not match, and the port that is operated under the auto-negotiation mode of operation is switched to pressure full duplex mode of operation, make that on the contrary dual-mode does not match, the packet loss phenomenon is even more serious, and network quality and stability of data transmission are poorer.
