S303, system are in PXAnd PyBetween repeat step S301, S302, until PXAnd PyBecome same node, represent
Through finding all of interruption MIP points on LSP；
The all interruption MIP points information found in S304, system record loop-back process；
All interruption MIP point results of the system according to record, on LSP Trail View, show LSP paths by graphical interfaces
Trouble point, according to MIP point results and LSP path failures display figure is interrupted, generates electronic troubleshooting work order, electronization everywhere
In troubleshooting work order, record has LSP path failure display figures, the business information of LSP impacts and LSP to safeguard user profile.
7. the system for realizing LSP quick detections based on loopback in PTN/IPRAN webmasters as claimed in claim 6, its feature exist
In：The MEGID is constituted using the character string that " the digital ID of type+equipment vendor's abbreviation+distribution automatically " is formed.
8. the system for realizing LSP quick detections based on loopback in PTN/IPRAN webmasters as claimed in claim 6, its feature exist
In：The MEPID and MIPID are natural numbers, and MEPID and MIPID starts to progressively increase every time from 1 according to natural number 1 to be carried out automatically
Numbering.
9. the system for realizing LSP quick detections based on loopback in PTN/IPRAN webmasters as claimed in claim 8, its feature exist
In：The mode that the source node MEPID=1, destination node MEPID=2, MIPID add 1 according to LSP path directions from 3 beginning hop-by-hops
Automatically distribute.
10. in the PTN/IPRAN webmasters as any one of claim 6 to 9 based on what loopback realized LSP quick detections it is
System, it is characterised in that：The LSP Trail View disposably shows the disconnected state on LSP paths using intuitively graphical interfaces,
Show multiple breakpoints, connected using normal green line between normal point, interrupting portion is represented using red line, and in failure
The red little fork pattern of point mark.
