Embodiment Construction

[0022] In this embodiment, a device shrinking method is provided. In this method, a scaling wizard is provided to guide the user to select the equipment to be scaled down, modify the network management optical connection, and the network management configures the relevant multiplex section protection group, multiplex section topology diagram, and protection relationship of related equipment according to the above information. and send it to the device. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Such as figure 1 As shown, the device shrinking method according to this embodiment includes: step S102, adding a shrinking lock to the system (optical network system), if the shrinking lock is added successfully, then perform step S104; if the shrinking lock cannot be added, then interrupt Processing; step S104, delete the equipment (SDH equipment, also called network element) to be scaled down from the...

Abstract

The invention discloses a method for equipment contraction, which includes: Step S102, add a contraction lock to a system, if the contraction lock is added successful, Sept S104 is performed, and if the contraction lock fails to be added, the procedure is interrupted; Step S104, delete the equipment to be reduced in network; Step S106, scan the spare interfaces of the equipment adjacent to the deleted equipment, and optical connection information is reestablished between the spare interfaces; Step S108, scan the multiplex-section protection group which the deleted equipment belongs to, identify the remained equipment in the multiplex-section protection group after the equipment deletion, and calculate the multiplex-section protection relation of the remained equipment according to the reestablished optical connection information and the multiplex-section protection relation of the multiplex-section protection group before the equipment deletion; and Step S110, calculate the related information of the remained equipment in the multiplex-section protection group after the equipment deletion. The invention can realize the smooth contraction of SDH equipment, reduce the risk caused bycontraction, enhance the contraction efficiency and shorten the service interruption time.

Description

technical field [0001] The present invention relates to the field of optical network communication, and in particular, relates to a device shrinking method. Background technique [0002] At present, in the practical application of Synchronous Digital Hierarchy (SDH) equipment, the following situations are often encountered: In an SDH equipment network, due to some reasons (for example, equipment aging needs to be replaced with new equipment) or network changes, etc.) need to be deleted from the network, and this situation can usually be called the shrinkage of SDH equipment. [0003] Usually, when the SDH equipment needs to be scaled down, if the SDH equipment to be scaled down involves multiplex section protection, the scale-down operation at this time will be very complicated, because the multiplex section protection is a part of the SDH equipment network. For crucial configuration, the network management system has a consistent judgment on its related data, and its speci...
