Embodiment 1

[0100] Mixed half-height boards and full-height boards are inserted in the same slot, and the Ethernet GE network port is automatically switched.

[0101] Figure 10 It is a schematic diagram of slot addresses 10, 17, and 30 of the subrack in Embodiment 1 of the present invention compatible with full-height boards and half-height boards. A, B, and X (equivalent to Figure 5The connectors of the illustrated embodiment) respectively represent the common signal socket of the half-height board and the common signal socket of the full-height board. In the following, the network port is used as the representative of the high-speed port for description, such as Figure 10 as shown,

[0102] When inserting two half-height boards, the slot addresses are 10 and 17 respectively. If inserting a full-height board, the slot address is 30. Since A and X on the left are not compatible, 2 network ports are required - 2 half-height boards are compatible with 1 full-height board and a total ...

Embodiment 2

[0109] Half-height boards and full-height boards are mixed in the same slot, and PCIE channels are switched adaptively.

[0110] Figure 11 It is a schematic diagram of slot addresses 10, 17, and 30 of the subrack in Embodiment 2 of the present invention compatible with full-height boards and half-height boards. A, B, and X (equivalent to Figure 5 The connectors of the illustrated embodiment) respectively represent the common signal socket of the half-height board and the common signal socket of the full-height board. The following uses PCIE as the representative of the high-speed port for description, such as Figure 11 Shown:

[0111] When inserting two half-height boards, the slot addresses are 10 and 17 respectively. If inserting a full-height board, the slot address is 30. In order to support PCIE multi-channel and multi-mode mixed insertion self-adaptation on the backplane, a PCIE master or PCIE switch chip is required to provide a 4-channel access connection to the...

Embodiment 3

[0117] Half-height boards, full-height boards, and double-layer full-height boards are mixed in the same slot, and PCIE channels are adaptively switched.

[0118] Figure 12 It is a schematic diagram of slot addresses 9, 10, 17, 18, 30, 31, and 60 of the subrack in Embodiment 3 of the present invention compatible with single-layer full-height boards, double-layer full-height boards, and half-height boards. A, B, C, D, S, L and X represent the common signal sockets of half-height boards, the common signal sockets of single-layer full-height boards and the common signal sockets of double-layer full-height boards, respectively. The following uses PCIE as the representative of the high-speed port for description, such as Figure 12 Shown:

[0119] When inserting four half-height boards, the slot addresses are 9, 10, 17, and 18 respectively. If inserting two single-layer full-height boards, the slot addresses are 30 and 31. If inserting double-layer full-height boards, the slot a...

Abstract

The invention provides a channel switching method and apparatus, a backboard, and a communication device. The method comprises the following steps: obtaining a plugging state of a specific slot in a communication device, wherein the plugging state comprises: a single board is plugged into a slot or the single board is unplugged from the slot, and the specific slot supports insertion of multiple types of single boards; obtaining the type of a single board corresponding to the plugging state in the specific slot; and according to the plugging state and the type of the single board, switching a current channel into a channel corresponding to the plugging state and the type. According to the invention, the problem of inflexible sub-frame configuration in related arts is solved, the flexibility of the sub-frame configuration is enhanced, and the utilization rate of a port is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a channel switching method and device, a backplane and communication equipment. Background technique [0002] In the field of communication, equipment such as Optical Transport Network (OTN for short), Packet Transport Network (PTN for short), and routers usually consist of a rack, one or more backplanes, and specific function boards. The backplane is connected through various input and output (IO) resources, and with the rapid development of DenseWavelengthDivisionMultiplexing (DWDM), PTN, OTN and other equipment, the transmission capacity and cross-connection capacity continue to increase, and The equipment replacement cycle is continuously shortened, which brings the problem of coexistence of multi-service and multi-generation products for operators or users. [0003] In order to meet such demands, the equipment is required to have a more flexible subrack configuration metho...
