Embodiment Construction

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

[0042] Such as 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:

[0045] Map the input and output ports of the optical layer switch matrix and the wavelengths or wavebands of the input and output ports to the input an...

Abstract

The invention discloses a photoelectric hybrid exchange internal path mapping method. According to the method, normalized identification is performed on forwarding information of an internal physical path and a logic path required by exchange of a light layer and an electric layer; a next hop address and a port number of a light user and an electricity user are identified in a unified way, and the service type and priority of each path of user are identified in the unified way; and then status information of a light-electricity exchange matrix is collected in real time, so as to establish a uniform internal path mapping table. Through adoption of the method, the internal path selection time is shortened, and exchange services of various granularities can flexibly select the optimal forwarding path of the light path or the electricity path, so that deep merging of multilayer exchange is realized.

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...
