Abstract

PURPOSE:To make processing to set a route again unnecessary by obtaining the information of the normality or the failure of respective switches within a switch group on the route from a subcontroller and selecting the route to pass through the normal switch group. CONSTITUTION:A sub-controller 2 controls a secondary switch 4, a third-order switch 5 and a fourth-order switch 6 as one switch group 8 under a main controller 1. Then, when a route setting command to set the route of the input and the output of the switch group 8 is received from the main controller 1, the sub-controller 2 selects the third-order switch 5 able to pass to set the route and sets the route with the secondary switch 4, the third-order switch 5 and the fourth-order switch 6. Thus, complicated processing becomes unnecessary.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a route setting method for a cross-connect device, and more particularly to a route setting method for a cross-connect device composed of switches arranged in a matrix.

[Conventional technology]

In the conventional cross-connect device route setting method, 5
A group of switches in which the sub-controller of a cross-connect device consisting of stage switches manages the secondary, tertiary, and quaternary switches, and the main controller considers the primary switch and the switches managed by the sub-controller as one switch. Although the main controller can recognize the failure of the tertiary switch by notification from the subcontrollers, when setting a path to the switch group, it ignores the failure of the tertiary switch and ignores the failure of the tertiary switch. Setting commands are being sent to the sub-controller.

[Problem to be solved by the invention]

In this route setting method for conventional cross-connect devices, even if a switch failure occurs, the main controller sends a route setting command to the subcontroller that manages the switch group, so the subcontroller that received the command The route cannot be set due to a switch failure, and the sub-controller sends a response to the main controller stating that the route cannot be set.
There is a problem in that complicated processing is required because a route setting command is sent to another subcontroller.

[Means to solve the problem]

The route setting method of the cross-connect device of the present invention includes a plurality of switch groups including a plurality of switches for setting a plurality of routes and a sub-controller for detecting the operating state of each switch, and setting based on the operating state of the input. and a main controller that outputs a route setting command to the switch group.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

In the cross-connect device of this embodiment, a sub-controller 2 under a main controller 1 manages a secondary switch 4, a tertiary switch 5, and a quaternary switch 6 as one switch group 8. When receiving a route setting command to set the input and output routes of group 8, the sub-controller 2 selects a tertiary switch 5 that can be passed through to set the route, and selects the secondary switch 4, the tertiary switch 5, and the quaternary switch. Set the route with switch 6.

In addition, the input terminal IN and output terminal O of the cross-connect device
When connecting the UTs, the main controller 1 selects a switch group 8 that can be passed through to configure a route, and causes the primary switch 3, switch group 8, and tertiary switch 7 to set the route. If the tertiary switch 5 fails, the sub-controller 2 detects this and notifies the main controller 1.

The main controller 1 has three normal switches for each switch group 8.
The number P of the next switches is stored in advance, and the number P of normal tertiary switches is updated based on the information about whether the tertiary switches 5 are normal or broken and which is notified from the sub-controller 2.

When the main controller 1 selects a switch group 8 for setting a route, each secondary switch 4 of each switch group 8
Alternatively, the number of routes already set in each quaternary switch 6 can be calculated as follows:
By selecting , when the main controller 1 sends a command to set the input and output routes of the switch group 8 to the sub-controller 2, the sub-controller 2 returns a response that setting is not possible due to a failure of the tertiary switch 5 to the main controller 1. You will no longer be exposed to it. Under these conditions, it can be easily derived from the theorem that when the three-stage switch of switch group 8 is configured as a non-blocking switch, the number of secondary switches 4 is 2a - 1 when it is configured with primary switches with input number a. I'm scared. In other words, even if the tertiary switch 5 is out of order, the number of routes to be set is Q+1, so 2
(Q+1)-1 or more tertiary switches 5 are required and 2
(Q+1)-1≦P, and Q+1≦ [Effects of the Invention] As explained above, when the main controller sets a route, the present invention provides information on whether each switch in a group of switches on the route is normal or malfunctioning. By selecting a route that passes through a group of normal switches obtained from the subcontroller, there is no need to set the route again, which reduces the processing time for setting the route, and also reduces the time required in the event of an error. This has the effect that processing can be easily performed at a later date.
