Problems solved by technology

[0002] Common photoelectric hybrid switching regards optical switching and electrical switching as two independent layers, and the forwarding basis is different. When photoelectric services interact, it will cause repeated table lookups, and internal route selection takes a lot of time, which is not conducive to internal switching of switches. centralized control of resources
At present, there is no internal path mapping method at home and abroad that can provide a unified switching basis for this multi-layer hybrid switching

Embodiment Construction

[0041] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] like figure 1 As shown, a method for internal path mapping of optical-electrical hybrid switching includes the following steps:

[0043](1) Collect the input and output port information of the electrical layer and the optical layer switch matrix, and set up a normalized mark, that is, generate a normalized switch input and output port number; the input and output port information includes the electrical layer Input and output port numbers, input and output port numbers of the optical layer, input and output wavelengths and wavebands of the optical layer;

[0044] The specific way to establish the normalized identification of input and output port information is as follows: the input and output ports of the optical layer switch matrix and the wavelengths or wavebands of the input and output ports are compared with the input and ...

Abstract

The invention discloses an internal path mapping method for optical-electrical hybrid switching. First, the forwarding information of the internal physical path and logical path required for the exchange of the optical layer and the electrical layer is normalized and marked: the next hop of the optical user and the electrical user The addresses and port numbers are uniformly identified, and the service types and priorities of all users are uniformly identified. Then collect the status information of the optical and electrical switching matrix in real time, so far establish a unified internal path mapping table. The present invention reduces the internal route selection time, enables flexible selection of the optimal forwarding path of optical paths or circuits for switching services of various granularities, thereby realizing deep integration of multi-layer switching.

Description

technical field [0001] The invention relates to a method for mapping an internal path of a photoelectric hybrid switch, which belongs to the technology of data communication transmission. Background technique [0002] Common photoelectric hybrid switching regards optical switching and electrical switching as two independent layers, and the forwarding basis is different. When photoelectric services interact, it will cause repeated table lookups, and internal route selection takes a lot of time, which is not conducive to internal switching of switches. Centralized control of resources. At present, there is no internal path mapping method at home and abroad that can provide a unified switching basis for this multi-layer hybrid switching. Contents of the invention [0003] The technical solution of the present invention is to overcome the deficiencies of the prior art and provide a method for improving the voice quality of a satellite communication network. The forwarding in...
