specific Embodiment 1

[0078] Specific embodiment one: Multi-service recovery after link interruption (reaching the maximum number of iteration calculations)

[0079] like Image 6 As shown, the topology consists of nodes A, B, C, D, E. The number next to the link is the number of wavelengths available on the link.

[0080] Services 1 to 10: the path is A-E-C. Links AE and EC occupy 10 wavelengths.

[0081] Services 11-20: the path is A-E-D. Links AE and ED occupy 10 wavelengths.

[0082] Services 21-30: the path is B-D. 10 wavelengths are occupied on link BD.

[0083] Services 31-40: the path is B-D-C. Links BD and DC occupy 10 wavelengths.

[0084] Now links A-E, B-D are broken.

[0085]Step 1: Determine the nodes and connected trees for global path calculation.

[0086] Step S101: the PCE module on node A monitors link flooding messages.

[0087] Step S102: detect the interruption of the link A-E, record the interrupted link AE, and set the timer to 10 seconds. The timer duration can ...

specific Embodiment 2

[0130] Specific embodiment two: multi-service recovery after link interruption (all request service recovery path calculation is successful)

[0131] like Figure 7 As shown, the topology consists of nodes A, B, C, D, E. The number next to the link is the number of wavelengths available on the link.

[0132] Services 1 to 10: the path is A-E-C. Links AE and EC occupy 10 wavelengths.

[0133] Services 11-20: the path is A-E-D. Links AE and ED occupy 10 wavelengths.

[0134] Services 21-30: the path is B-D. 10 wavelengths are occupied on link BD.

[0135] Services 31-40: the path is B-D-C. Links BD and DC occupy 10 wavelengths.

[0136] Now links A-E, B-D are broken.

[0137] Step 1: Determine the nodes and connected trees for global path calculation.

[0138] Step S101: the PCE module on node A monitors link flooding messages.

[0139] Step S102: detect the interruption of the link A-E, record the interrupted link AE, and set the timer to 10 seconds. The timer durat...

specific Embodiment 3

[0166] Specific embodiment three: multi-service recovery after link interruption (topology becomes multiple connected trees)

[0167] like Figure 7 As shown, the topology consists of nodes A, B, C, D, E. The number next to the link is the number of wavelengths available on the link.

[0168] Services 1 to 10: the path is A-E-C. Links AE and EC occupy 10 wavelengths.

[0169] Services 11-20: the path is A-E-D. Links AE and ED occupy 10 wavelengths.

[0170] Services 21-30: the path is B-D. 10 wavelengths are occupied on link BD.

[0171] Services 31-40: the path is B-D-C. Links BD and DC occupy 10 wavelengths.

[0172] Now links A-B, A-E, C-E, C-D, B-D are broken.

[0173] Step 1: Determine the nodes and connected trees for global path calculation.

[0174] Step S101: PCE modules on nodes A and B monitor link flooding messages.

[0175] Step S102: detect link A-B interruption, record the interrupted link AB, and set the timer to 10 seconds. The timer duration can b...

Abstract

The invention provides a service operation method and device, a storage medium and an electronic device. The method comprises the following steps: determining the service information of each node in adistributed network after determining that a link in the distributed network is interrupted; calculating a recovery path for the service set indicated by the service information of each node; and operating the service by using the recovery path. According to the invention, the problems of resource conflicts and incapability of global resource optimization in related technologies are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a service operation method, device, storage medium and electronic device. Background technique [0002] With the continuous development of Automatically Switched Optical Network (ASON) technology, more and more service providers have begun to use optical network equipment to build networks, and realize automatic calling by loading control planes inside nodes. Path calculation and connection establishment. Both a connection controller (Connection Controller, CC for short) and a path computation element (Path Computation Element, PCE for short) are components of the control plane. The PCE is responsible for completing the calculation of the entire call path, and the CC completes the establishment of the entire connection by issuing label reservation and cross-connection establishment to each node along the path according to the calculation result of the PCE. [0003] To complet...
