For the embodiment of the present invention being set forth clearly clear, provide below the better embodiment of the embodiment of the present invention。
This better embodiment provides the method that the network side fault of a kind of Packet Transport Network is transmitted, the method that especially in PTN network, the network side fault of a kind of Packet Transport Network is transmitted to user side to user side。
In field of data transmission, one end, user side has fault to need to allow other end user side perceive fault, in order to avoid other end user side continues to send Business Stream waste bandwidth。Such as, scene such as Fig. 1, two user CE1 and CE2 of PTN network user side carry out communication respectively through two fringe node PE1 and PE2 accesses of PTN network, link or node failure when CE1 side, require over a kind of technology to allow the CE2 node perceived of network opposite end to this fault, and when after the failure vanishes of CE1 side, allow CE2 perceive failure vanishes。
User side Fault Mapping (Mapping) is to network side fault, and this part realizes in OAM, is not described in detail in this。This better embodiment continuity user side fault Mapping of having been carried out of OAM is to network side fault, the method that invention network side fault is transmitted to user side。
The method that the network side fault of Packet Transport Network is transmitted to user side is realized to break-through (LST) function of ethernet port Link State by service layer, the time index requirement that the content of this better embodiment includes link break-through function and Link State penetrates。
Link break-through function includes, and private line service AC fault (UNI side) triggers local terminal pseudo-wire (PW) to ACMapping；Private line service NNI side fault triggers PW to ACMapping；Private network business AC fault (UNI side) triggers PW to ACMapping；Private network business NNI side fault；
Private line service AC fault (UNI side) triggers local terminal PW to ACMapping, as shown in Figure 1, far-end AC fault, far-end AC to pwMapping sends Client Signal Fail alarm (CSF) message, and the CSF condition of local terminal perception pw also enables pw to ACmapping function local terminal AC port is set to LSTdown。
Private line service NNI side fault triggers PW to ACMapping, as it is shown on figure 3, break down in NNI side, such as PW fault (being not limited to PW fault), when pw detects that above-mentioned fault enables pw to ACmapping function and AC port is set to LSTdown。
Private network business AC fault (UNI side) triggers PW to ACMapping, as shown in Figure 4, private network business U side fault, ROOTAC to pwMapping sends CSF message, and the CSF condition of LEAF node perceived pw enables pw to ACmapping function and AC port is set to LSTdown。
Private network business NNI side fault, as shown in Figure 5 when opposite end multiple node pw detects that above-mentioned fault enables pw to ACmapping function and AC port is set to LSTdown。
Link penetrates LST time index, and LSTdown/up should meet and uses what this event carried out pretection switch quickly to switch requirement。Wherein light mouth needs to meet 100ms time index, and electricity mouth meets second level。
State each key technology point below:
In order to convenient describing, the module in this invention named, names as follows:
Router operating system: RouterOperatingSystem, ROS；
Forward table management module: ForwardingTableManage, FTM；
Product administration module: ProductManage, PM；
Field programmable gate array module: FieldProgrammableGataArray, FPGA；
User side interface: UserNetworkInterface, UNI；
Network Side Interface: NetworkNetworkInterface, NNI；
1. during network side fault, fault message is passed to user side, user side response fault message
For ensureing typical scene (scene as escribed above) LSTdown time index, network side fault passes to user side following step:
NNI line card FPGA detects that pwCSF/LOC/AIS/RDI notifies master control FPGA immediately；
Master control FPGA carries out Mapping and records the LSTdown state of uni port simultaneously, and LSTdown state suppresses the Mapping of AC to PW；
Master control FPGA notifies that UNI line card FPGA implements AC port LSTdown, in this process such as Fig. 5 shown in blue lines；
UNI line card FPGA close port laser machine realizes the LSTdown of port；
2. during network side failure vanishes, failure vanishes information is passed to user side, user side response failure vanishes information
If the alarm that LST is triggered in pw side disappears, needing to cancel LST state, step is as follows:
NNI line card FPGA detects that pwCSF/LOC/AIS/RDI alarm disappears and notifies master control FPGA immediately；
Master control FPGA records LSTup state, and notifies that UNI line card FPGA implements AC port LSTup；
Master control FPGA state judges whether to need lower slotting CSF after postponing 6s lower slotting CSF, 6s from LSTdown to LSTup again, in this process such as Fig. 6 shown in blue lines；
3. deadlock scenario solutions
As shown in Figure 8, if PE node A and PE node B enables Mapping, LST and CSF function, then it is likely to occur in figure one end AC fault, causes two ends deadlock situation。Cause deadlock process as follows:
1. the AC port of network element A causes AC port linkdown due to disconnected fibre；
2. the AClinkdown of network element A triggers AC to pwMapping；
3. pwCSF is sent to network element B from network element A；
4. the pwCSF of network element B triggers pw to ACMapping；
5. the AC interface enabling of network element B LST, according to Mapping result by AC port linkdown；
6. the AClinkdown of network element B triggers AC to pwMapping；
7. pwCSF is sent to network element A from network element B；
8. the pwCSF of network element A triggers pw to ACMapping；
9. the source of the AC port linkdown of network element A becomes disconnected fibre and the LSTdown linkdown caused。
Occur after said process, even if the AC fiber port of network element A recovers, the AC port of A network element and B network element still can not linkup, be in two ends deadlock state。For avoiding said process, it is necessary to AC port is in LSTdown state and suppresses AC to PWMapping, namely there is not 6. 7. 8. process in the upper figure of guarantee。
