Embodiment
In order to not destroy the transmission of normal Ethernet service while supervising network, main use Ethernet splitter, the effect of the Ethernet splitter of the communications field is, realizes the data acquisition of ethernet line while not destroying the transmission of normal Ethernet service.
With reference to shown in Fig. 1, normal ethernet line is truncated, the A port of difference access network based on ethernet splitter and B port, its bidirectional transmit-receive data are collected to be exported from C mouth, the data of A port accepts need to export from B port simultaneously, the data of B port accepts need to export from A port, and namely A port realizes loopback with B port and is connected, and keeps normal Ethernet service not to be destroyed thus.
According to the specification that Ethernet connects, when two network element interface speed are inconsistent, actual connection speed is as the criterion with low rate.As shown in Figure 2, when when the first network element interface is 1000Mbps, the second network element interface is 100Mbps, actual connection speed is 100Mbps, and two network elements can proper communication.
A, B port of usual Ethernet splitter all adopts the adaptive mode of port speed, so for above-mentioned situation, will occur the situation that A, B port speed is inconsistent.
With reference to shown in Fig. 3, A port and B port are connected with two network elements respectively, and owing to all taking adaptive mode, the first network element will with 1000Mbps two-forty transceiving data, and the second network element will with 100Mbps low rate transceiving data, final result causes the second net element communication fault.Common settling mode needs user manually cancel the self adaptation of A port and force port speed to be 100Mbps.When the network element speed that A port connects changes, user is also needed manually to recover the adaptive characteristic of A port.This mode needs user manually to intervene, and automatic recovery capability is weak, bad adaptability.
In order to solve the problem, realize the synchronous of Ethernet Channelizer port speed, the invention provides a kind of method keeping Ethernet Channelizer port speed synchronous.According to ethernet specification, when port speed changes, need port to connect and disconnect.In adaptive process, local terminal capability advertisement can be configured, the speed grade notice opposite end that local terminal can be supported.
For the Ethernet splitter that the port speed of A, B shown in Fig. 3 is inconsistent, wherein the speed of A port is 100Mbps, the speed of B port is 100Mbps, if do not adjust, final result causes the second net element communication fault, with reference to the flow chart shown in Fig. 4, the method step keeping Ethernet Channelizer port speed synchronous is as follows:
The connection status of A, circular test Ethernet splitter two ports, if unanimously, proceeds step B, if inconsistent, after re-starting adjustment to the state of port, continues the connection status of circular test Ethernet splitter two ports.
In example, the connection status of Ethernet splitter circular test Ethernet splitter A port and B port, if the state consistency of A port and B port, then carries out step B, if inconsistent (as one end has connection one end not connect), then carries out step a.
Whether the speed of B, inspection Ethernet splitter two ports is consistent, if unanimously, then returns the connection status that steps A continues two ports of cycle detection Ethernet splitter, if inconsistent, then forward step C to.
Check in example that whether Ethernet splitter A port is consistent with the speed of B port, if unanimously, then return the connection status that steps A continues cycle detection Ethernet splitter A port and B port, if inconsistent, then forward step C to.In this example, the speed of the speed ratio B port of A port is high, therefore enters step C.
The two-forty capability advertisement of C, closing high-speed rate port, and make its adaptive connection again, after two-forty autosensing connects, the speed of Ethernet splitter two ports becomes unanimously, and returns the connection status that steps A continues two ports of cycle detection Ethernet splitter.
The 1000Mbps capability advertisement of A port is first closed in example, and allow A port adaptive connection again, because the two-forty capability advertisement of A port is closed, therefore A port can only be operated in the state of 10 or 100 mbps, therefore when A port again self adaptation, communicate with the first network element with the speed of 100Mbps, thus make A port consistent with the speed of B port.
If the speed of B port is 10Mbps, A port speed is 1000Mbps, then first A port closes the capability advertisement of 1000Mbps, then self adaptation and the first network element are with the rate communication of 100Mbps, then steps A is returned, again the speed of two ports is detected after forwarding step B to, carry out step C further, the 100Mbps capability advertisement of A port is closed in step C, A port can only be worked under the state of 10Mbps, allow its adaptive connection again, with the first network element to work under the speed of 10Mbps, thus make the consistent of the speed of A port and B port.
As the further improvement of such scheme, when detecting in steps A that the connection status of Ethernet splitter two ports is inconsistent, following methods step is adopted to re-start adjustment;
A, judge its port broken before whether be forced disconnect, if be forced before disconnect, then continue step b; If not, then forward step c to.
If detect in steps A, the state of A port and B port is inconsistent, as B port does not connect, then forwards this step a to, judge again in step a B end before whether be forced disconnect, if connection status inconsistent be because B port before be forced disconnect, then forward step b to, if not, then forward step c to.
B, recover the port that is forced to disconnect, adaptive connection again, returns the connection status that steps A continues two ports of cycle detection Ethernet splitter.
In example, step b recovers the B port being forced to stop, and makes its adaptive connection again, then returns the connection status that steps A continues to detect A port and B port.
C, force to disconnect the port keeping connecting, then open the capability advertisement of two ports, and adaptive connection again, then return the connection status that steps A continues two ports of cycle detection Ethernet splitter.
In example, Ethernet splitter detects that B port does not connect and B port is not forced closed, then go to step c process, if A port closes two-forty capability advertisement in order to the speed that is consistent with B port, at this moment two-forty network element is replaced with the second network element of B port communication, if just use step b to recover B port simply and allow its adaptive connection again, when again forwarding steps A to, only can by the rate reduction of B port, the speed of A port can't be improved, thus make network can not get sufficient utilization, when detecting that B port is not without when connecting because being forced disconnection in step a, force to disconnect the A port keeping connecting, and open A, the capability advertisement of B port, then its self adaptation is again allowed, if the second network element speed be connected with B port improves, because open the capability advertisement of A port, A port and B port can be adjusted to the highest state of speed in step B and step C, the present invention is allowed to design more perfect, network can be made full use of, do not need manually to adjust Ethernet splitter.
A kind of method keeping Ethernet Channelizer port speed synchronous that the present invention adopts, when finding that Ethernet splitter two-port speed is inconsistent, automatically by two-forty grade port automatic adaptation to low rate grade, avoid the situation that appearance two port speeds are inconsistent, guarantee network element proper communication.
The above, just preferred embodiment of the present invention, the present invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
