Description
Technical field
The present invention relates to the communications field, relate more specifically to a kind of operation, management, with processing method and the equipment safeguarded, it is particularly useful for Ethernet virtual private line service.
background technology
At present, current techniques has realized OAM (operation, management, with safeguard) the partial function demand of L2VPN (Layer 2 virtual private network), meanwhile, for AC (accessory circuit) and PW (pseudo-line) situation whether type is identical, also there is corresponding technical scheme.
In correlation technique, CE (client edge device) might not directly be connected with PE (provider edge equipment), but may there is local network N, for example, as shown in Figure 1, CE1 is connected with PE1 by network N 1, CE2 is connected with PE2 by network N 2, has pseudo-line (PW) (not shown), wherein between PE1 and PE2, N1 and N2 refer to Ethernet, and the direction of arrow in figure represents to receive or sending direction.
In the technical scheme of correlation technique, defined the defect type of PE (provider edge equipment), wherein, forward defect and refer to the fault that affects reception information, reverse defect refers to the fault that affects transmission information, particularly, as shown in Figure 2, AC (accessory circuit) forwards defect and refers to the fault that affects PE reception local terminal AC directional information, and the reverse defect of AC refers to that affecting PE transmits information to the fault of local terminal AC direction.Similarly, PW (pseudo-line) forwards defect and refers to the fault that affects PE reception PW directional information, and the reverse defect of PW refers to that affecting PE transmits information to the fault of PW direction.
PE1 will be the preliminary warning notice of local terminal PW and AC1 to PE2 and CE2, and PE2 will be the fault notification of local terminal PW and AC2 to PE1 and CE1, to allow the fault that CE and PE can perception far-end.
For dissimilar AC (accessory circuit) business, such as ATM, Ethernet etc., the defect judgement of PW can be duplicate with noticing.But for the notice of AC defect, depend on the OAM mechanism of concrete AC type.For the AC business of Ethernet type, in prior art, do not introduce Ethernet OAM mechanism, be implemented as follows:
(1) PE (provider edge equipment) enters the standard that AC (accessory circuit) forwards defect state: when alarm appears in the upper Ethernet mouth physical layer that is connected with AC of PE, PE enters AC and forwards defect state;
(2) PE leaves the standard that AC forwards defect state: when all alarms that the Ethernet mouth physical layer that is connected with AC on PE occurs have all recovered, PE leaves AC and forwards defect state;
(3) PE enters the executive program that AC forwards defect state: to opposite end PE, notice local end PE and forward defect state (opposite end PE receives that the processing after notice defines) because AC fault enters PW;
(4) PE leaves the executive program that AC forwards defect state: to opposite end PE, notice local end PE because PW forwarding defect state (opposite end PE receives that the processing after notice defines) is left in AC fault recovery;
It can be seen from the above, at present for PE, when enters the reverse defect state of AC, PE and when leave the reverse defect state of AC, PE and enter PW and forward the implementation of defect state and PE and leave the problems such as implementation that PW forwards defect state and do not relate to.
Therefore, in existing scheme, AC fault-detecting ability to Ethernet type is very limited, only has link failure, for example, the fault of N1 can not be found by CE (custom edge client edge device) and PE (provide edge provider edge equipment), the fault of N1 can not be noticed to PE2 and CE2, in addition, the fault of CE1 can not be noticed to PE1, PE2 and CE2, causes like this PE (provider edge equipment) cannot enter smoothly or leave the process of specific defects state.
Summary of the invention
The present invention is devoted to overcome the inherent shortcoming in above-mentioned correlation technique, for this reason, the invention provides a kind of operation, management, with processing method and the equipment safeguarded.
