Embodiment
Below, in conjunction with the accompanying drawings the embodiment of the invention is described in detail.
802.3ah the infomational message structure of protocol definition as shown in Figure 2, the field that OAM configuration field wherein (OAM Configuration) need compare when being exactly the terminal device negotiation, size is 1 byte, every implication as shown in Figure 3A, Fig. 3 B then shows everybody implication of Flags territory (being " marker bit " among Fig. 3 A) in this message structure.
Such as in Fig. 3 A, if the 1st is 1, represent that then this port supports this function of single-pass, if the 2nd is 0, represent that then this port do not support this function of remote loopback.
In an embodiment as shown in Figure 5, the OAM detecting pattern of first port is set to passive (can be called " Partner "), promptly, the OAM pattern (OAM Mode) of OAM configuration field is made as 0, the OAM detecting pattern of second port is set to initiatively (can be called " drive end "), that is, the OAM pattern (OAM Mode) with the OAM configuration field is made as 1.
After 501: the first ports are received the negotiation packet that second port sends, can resolve the OAM configuration field in the message, whether support any one (hereinafter referred to as " resolving the position ") pairing function in the OAM configuration field so that judge drive end, during parsing, can take the mode of resolving by turn, such as: resolve by turn since the 1st,, represent that then the drive end port supports this function of single-pass if the 1st is 1; Certainly, also can take other analysis mode,, resolve selectedly after everybody, resolve other positions again such as some the parsings of choosing earlier wherein.
Be understandable that, in various embodiments of the present invention, negotiation packet can be the various messages that have the OAM configuration field, are used for carrying out the OAM configuring negotiation, such as the 802.3ah hello packet, certainly, one of ordinary skill in the art will appreciate that the negotiation packet in the embodiment of the invention is not limited to the 802.3ah hello packet.For convenience of description, various embodiments of the present invention are that example describes with the 802.3ah hello packet all.
502:, can judge then whether Partner is also supported to resolve the pairing function in position, if Partner is also supported this function, then changes 506, if do not support this function, then changes 503 if the pairing function in position is resolved in the drive end support;
503: if the pairing function in position is resolved in the drive end support, Partner is not supported this function, then stops resolving;
504:, can judge also whether local terminal supports to resolve the pairing function in position, if Partner is supported this function, then changes 505, if Partner is not supported this function, then changes 506 if drive end does not support to resolve the pairing function in position;
505: if drive end does not support to resolve the pairing function in position, the pairing function in position is resolved in the Partner support, and then Partner shields this function;
506: judge whether also have the position of not resolving in the OAM configuration field,, then change 507, otherwise consult to finish if also have;
507: if also have the position of not resolving, then resolve the position of not resolving, change 501.
When the OAM configuration field of first port in the 802.3ah hello packet that second port is sent resolved, resolving the position is 0 o'clock, if first port is supported this corresponding function, then can advanced line item, and resolve other positions (if also having the position of not resolving), up to all positions of having resolved the OAM configuration field, at last first configuring ports and second port are carried out synchronously, that is, first port itself is supported that still the unsupported function of second port shields.
Certainly, can be 0 and first port when supporting this corresponding function also resolving the position, first port carries out in real time synchronously, first port itself is supported but the unsupported function of second port shields, and has shielded to resolve next bit afterwards again.
As shown in Figure 4, the OAM pattern of A port has been configured to aggressive mode, and the OAM pattern configurations of B port is a Passive Mode.The A port of aggressive mode can send a 802.3ah hello packet to the B port, receive this message after, the B port can be resolved by turn to the OAM configuration field that carries in the message.
Because the OAM pattern in the OAM configuration field has configured in advance,, directly resolve since the 1st (whether expression supports single-pass) so the B port can not resolved the 0th (being the OAM pattern) yet herein.In the process of resolving, if to resolve the position be 1 and itself support to resolve the pairing function in position, then continue to resolve next bit, if to resolve the position be 1 and itself do not support to resolve the pairing function in position, then stop resolving, consult failure; If to resolve the position be 0 and itself support to resolve the pairing function in position, then this function is shielded, if to resolve the position be 0 and itself do not support to resolve the pairing function in position, then continue to resolve next bit.
Such as, if the OAM configuration field of A port is respectively shown in the following table one:
| The position | Value | Implication |
| 7:5 | 000 | Reserved |
| 4 | 0 | Do not support the |
| 3 | 1 | |
| 2 | 0 | Do not support |
| 1 | 1 | Support single- |
| 0 | 1 | Aggressive mode |
Table one
And the OAM configuration field of B port is respectively shown in the following table two:
| The position | Value | Implication |
| 7:5 | 000 | Reserved |
| 4 | 1 | Support the |
| 3 | 1 | |
| 2 | 1 | Support |
| 1 | 1 | Support single- |
| 0 | 0 | Passive Mode |
Table two
Then after the B port is received the hello packet that the A port sends, can resolve successively the OAM configuration field everybody:
The 0th relates to the OAM detecting pattern, can resolve;
When resolving the 1st, find that two ports all support single-pass, then continue to resolve the 2nd;
When resolving the 2nd, discovery A port is not supported remote loopback, and itself supports then to carry out record by remote loopback, perhaps shields this moment, and this remote loopback function is shielded;
When resolving the 3rd, find that two ports all support link event, then continue to resolve next bit;
When resolving the 4th, discovery A port is not supported the variable request, and itself supports the variable request, then carries out record, perhaps shields this moment, and variable request function is shielded.
From the 5th to the 7th, if keeping the position, these are not used, then can select not resolve and also can select to resolve, because in this case, it is just the same that these positions all are set to complete 0, two setting of ports.Certainly, also be used, then can select to resolve if these keep the position.
If in the resolving, do not carry out functional shielding in real time in front, and don't the situation of exist to need stop consulting, then can be after having resolved all again unification shield.
In another embodiment, the OAM pattern is after first port of Passive Mode receives that the OAM pattern is the message sent of second port of aggressive mode, the OAM Configuration territory in the described message to be resolved:
If resolve the position is that the represented function in position is resolved in the 1 and first port support, and then the two ends configuration consistency if also have other positions not resolve, then continues to resolve;
If resolve the position is that 1 and first port does not support to resolve the represented function in position, then stops resolving;
If resolve the position is that the pairing function in position is resolved in the 0 and first port support, judges then whether this function is set to essential by first port user:
If essential function then stops consulting, the 3-4 position in message Flags territory is filled out 0,0 respectively, the dissatisfied opposite end (that is, second port) of expression local terminal (that is, first port) disposes, and corresponding item is filled out in the 5-7 position in OAMConfiguration territory; Such as: if to the 1st of OAM Configuration territory dissatisfied, 001 expression is inserted in the 7-5 position in OAM Configuration territory.
If the essential function of right and wrong then shields this function at local terminal (that is, first port),, continue to resolve if also have other positions not resolve;
If resolve the position is that 0 and first port does not support to resolve the pairing function in position, then can write down this situation earlier, if also have other positions not resolve, then continues to resolve, if consult successfully at last, then shields this function at local terminal (that is first port).
Behind the 0-4 position of having resolved OAM Configuration territory, the 3-4 position in message Flags territory is filled out 0,1 be satisfied with opposite end (that is second port) configuration respectively.If the configuration of dissatisfied opposite end then all fills out 0 with the 3-4 position in message Flags territory.
Generally speaking, the function that can not support simultaneously for two ends, if this function belongs to the essential function of Partner, then Partner can be unsatisfied with the configuration of drive end, and, the numbering that the position of this kind situation generally first can be occurred is filled up to the 7-5 position in OAM Configuration territory, and is dissatisfied to the 1st of drive end OAMConfiguration territory as Partner, and 001 expression is inserted in the 7-5 position in OAM Configuration territory.
Second port (that is, Partner) is received the negotiation packet that first port (that is, drive end) is responded, and at first resolves the 3-4 position in Flags territory:
If be the configuration of the dissatisfied local terminal (drive end) in 00 expression opposite end (that is, Partner), consult failure (to the dissatisfied reservation position that can go to resolve OAM Configuration territory of which kind of configuration), if be 01, then represent the satisfied local terminal configuration in opposite end.
Because in real network, port arrangement changes sometimes, so, second port can also be in the opposite end (promptly, first port) be satisfied with under the situation of local terminal (that is, second port) configuration, the 0-4 position of resolving the OAM Configuration territory of opposite end successively guarantees that further two ends dispose:
If resolve the position is that the represented function in position is resolved in the 0 and second port support, then at second port this function is shielded;
If resolve the position is that 0 and second port does not support to resolve the represented function in position yet, if also have the position of not resolving, then continues to resolve;
If resolve the position is that the represented function in position is resolved in the 1 and second port support, if also have the position of not resolving, then continues to resolve;
If resolve the position is that 1 and second port does not support to resolve the represented function in position, then starts this function at local terminal.
Like this, the A port that is set to Passive Mode just can " be tried one's best ", makes OAM configuration mode of oneself and B port keep being arranged to identical configuration and need not the A port in advance with the B port synchronously, has simplified configuring ports work.Even A port and B port are respectively the distinct devices of different manufacturers, in the process of carrying out 802.3ah intercommunication negotiation, can not cause to consult success because of to the tenability difference of two-port to various functions yet.
The embodiment of the invention also provides a kind of communication equipment, among the embodiment as shown in Figure 6, the OAM pattern of this equipment is Passive Mode (correspondingly, this port is called " passive port "), comprises message receiver module 61, packet parsing module 62 and processing module 63:
Wherein, message receiver module 61 is used to receive the negotiation packet that the port that the OAM pattern is an aggressive mode (can be called " active port ") initiates (as, 802.3ah hello packet);
And processing module 63 can also specifically comprise judge module 631, and being used at the analysis result that packet parsing module 62 sends is that active port is not supported and passive port support when resolving the pairing function in position, judges whether this function is essential function;
Like this, the communication equipment that is set to Passive Mode just can " be tried one's best ", the OAM configuration mode of oneself and the communication equipment of aggressive mode are kept synchronously, and two equipment that need not is arranged to identical configuration in advance, have simplified configuring ports work.Even two equipment are respectively the distinct devices of different manufacturers, in the process of carrying out 802.3ah intercommunication negotiation, can not cause to consult success because of to the tenability difference of two device ports to various functions yet.
The embodiment of the invention also provides a kind of communication system, comprise first port and second port, wherein, it is passive that the first port OAM detecting pattern is set to, that is, the OAM detecting pattern that the OAM pattern (OAMMode) of OAM configuration field is made as 0, the second port is set to initiatively, that is, the OAM pattern (OAM Mode) with the OAM configuration field is made as 1.
In this system, second port is used to initiate negotiation packet (as the 802.3ah hello packet); First port then is used to receive described message, and the OAM configuration field in the message is resolved, and the pairing function in position is resolved in the first port support if second port is not supported, then first port shields this function.
And first port can also comprise:
