Problems solved by technology

It is very simple to do this, but there are many disadvantages: a large amount of shielding information is transmitted through the network, which usually takes a long time; putting it into the device storage will cause a lot of pressure on the device's memory, and even the capacity of the device will exceed the limit. Paralyzed, resulting in interruption of user services; too many alarm reporting comparisons, making alarm reporting inefficient

Embodiment 1

[0027] The alarm masking data compression device involved in this example is used to realize the alarm masking data compression method, including: a status flag module, which obtains the settable alarm masking data, establishes a maskable tree according to the hierarchical relationship, and sets each The node status of the node, the node status includes full shielding status, partial shielding status, and unshielding status; the status update module updates the node status of the shieldable tree; the compression module compresses the shielding tree according to the hierarchical relationship and the traversed node status, and gradually Layer pruning of all nodes below the fully shielded state node, the unshielded state node itself and all nodes below it; the remaining shieldable tree after pruning is the compressed shielding tree, and the compressed alarm shielding data is obtained.

Abstract

The invention discloses a compression method of alarm mask data. The compression method comprises the following steps: acquiring the alarm mask data, establishing a maskable tree according to hierarchical relation and setting up a node state of each node of the maskable tree, wherein, the node state comprises a fully masked state, a partially masked state and a non-masked state; and updating the node state of the maskable tree; compressing the maskable tree according to the hierarchical relation and traverse node state; and gradually omitting all the nodes below the nodes in the fully masked state, the nodes in the non-masked state and the nodes below the nodes in the non-masked state. The compression method of the alarm mask data helps greatly reduce alarm mask information, quicken transmission of the mask information, reduce burden of equipment memory, shorten comparative alarm and reporting time of net elements, quicken reporting and improve system performance.

Description

technical field [0001] The invention relates to the field of optical transmission, in particular to an alarm shielding technology in the field of optical transmission. Background technique [0002] Alarm masking is one of the most commonly used functions of transmission equipment. In actual equipment, each network element contains multiple boards, and each board has multiple ports, and each port contains several or even dozens of alarm items. This network element, single board, port, and alarm hierarchy on the port cause the number of maskable data to increase in series, resulting in a huge amount of data, which brings great inconvenience to the transmission, storage, and use of masked information. For example, an SDH network element has 4 STM-64 optical boards under it, and there are 4 physical termination points PTP under each optical board, and there are 128 connection termination point CTPs under each PTP, and each CTP has an average of 20 alarm items, then The total n...
