CN101389149A - Batch processing method applied in ASON - Google Patents

Abstract

The invention discloses a signaling batch processing method applied in automatic switching optical network, comprising: firstly, classifying service according to service attribute, wherein service of same source, same destination, and same quality of service requirement are classified into one group; secondly, selecting routing by source nodes of the service group on the basis of satisfying all service bandwidth at one time; if success, initiating batch process signaling base on service group along the path; if failure due to inadequate capacity, dividing the batch connection based on every service load path in the service group, then initiating batch process signaling for connection establishment; if a part of the service is unable to be routed after the division, these services are denied for connection establishment; and thirdly, if only a part of services in batch services can be successfully established on the predetermined path in connection establishment process of signaling batch processing, residue services are returned to the source node by the signaling batch processing. The invention enhances efficiency of the signaling protocol in prior art.

Description

Be applied to the signaling batch processing method of ASON

Technical field

The present invention relates to the optical network communication field, especially relate to the signaling batch processing method that is applied to ASON.

Background technology

In ASON (ASON), can finish establishment of connection, modification, maintenance and dismounting dynamically by distributed signaling control, thereby realize that the dynamic business of optical-fiber network provides and allocated bandwidth, significantly reduced the setup time of new business and reduced the operation cost of network.Traditional signaling protocol is based on the wall scroll business realizing at establishment of connection, when removing.Therefore, along with the increase of number of services, cause professional settling time, failure condition to enlarge markedly professional recovery time down, the load of signaling communication network (SCN) significantly increases.Simultaneously, owing in the ASON network, have a large amount of homology chummages, have the business of same services quality requirement, therefore, people attempt existing signaling technology is improved, to improve the efficient of existing signaling protocol, thereby shorten professional foundation and failure recovery time, reduce the load of SCN.But yet there are no the report of all relevant this respects.

Summary of the invention

The object of the invention is to propose a kind of signaling batch processing method that is applied to ASON that improves signaling protocol efficient.

For achieving the above object, the present invention can take following technical proposals:

The signaling batch processing method that is applied to ASON of the present invention comprises the steps:

The first step: according to service attribute business is divided into groups, the business of homology, chummage, same services quality requirement is divided into one group, be called service groups;

Second step: the source node of service groups is at first by selecting routes by interior all service bandwidths of all promising policy service groups; If the route success then initiates to connect the batch processing signaling of setting up along this path based on service groups; If because off-capacity and route are unsuccessful, then share the path based on each the bar business in the service groups this batch connection is cut apart, distribution principle is that each bar is shared the maximum number of connections that the path can hold, and initiates to connect the batch processing signaling of foundation then; Still have in the service groups partial service can't route if cut apart the back, then these business be rejected and connect;

The 3rd step: set up in the process in the connection of signaling batch processing, because network state temporary transient asynchronous causes turning back of signaling, be to have only partial service on predefined paths, to set up successfully in this batch traffic, in this case, Sheng Xia business will be gone back to source node routing again by the signaling batch processing.

Owing to take abovementioned technology, the present invention to have the following advantages and effect:

1, improves the efficient of existing signaling protocol, shortened the time of professional foundation and fault recovery;

2, reduce the quantity of signaling process, reduced the load of signaling communication network (SCN).

Embodiment

Embodiment:

In order to describe method of the present invention in detail, and advantage more of the present invention and effect, this with a real network be example in conjunction with the accompanying drawings.

Network as shown in Figure 2, internodal capacity is shown in the numeral on the circuit among Fig. 2.Node A has 3 business to Node B, is respectively S1, S2, S3, and professional bandwidth is respectively 1, and professional quality of service requirement is identical.

The first step is divided into one group with S1, S2, S3, is designated as TG1; The total bandwidth of TG1 is 3.

In second step, source node A carries out routing to TG1, does not have once to carry the route of whole service group; Service groups is cut apart routing, and the result is:

TG1-1: comprise S1, route is: A-〉B-〉D;

TG1-2: comprise S2, S3, route is: A-〉C-〉D;

TG1-1 batch processing signaling connects to be set up successfully.

In the 3rd step, when the batch processing signaling of TG1-2 successfully is set up to C, find that the capacity of C-D only is left 1; TG1-2 is subdivided into once more:

TG1-2-1: comprise S2, route is A-〉C-〉D, connect and set up successfully;

TG1-2-2: comprise S3, signaling is turned back to the A point, routing again, route is A-〉C-〉B-〉D, connect and set up successfully.

Claims (1)

1, a kind of signaling batch processing method that is applied to ASON, it is characterized in that: it comprises the steps:

The first step: according to service attribute business is divided into groups, the business of homology, chummage, same services quality requirement is divided into one group, be called service groups;

Second step: the source node of service groups is at first by selecting routes by interior all service bandwidths of all promising policy service groups; If the route success then initiates to connect the batch processing signaling of setting up along this path based on service groups; If because off-capacity and route are unsuccessful, then share the path based on each the bar business in the service groups this batch connection is cut apart, distribution principle is that each bar is shared the maximum number of connections that the path can hold, and initiates to connect the batch processing signaling of foundation then; Still have in the service groups partial service can't route if cut apart the back, then these business be rejected and connect;

The 3rd step: set up in the process in the connection of signaling batch processing, because network state temporary transient asynchronous causes turning back of signaling, be to have only partial service on predefined paths, to set up successfully in this batch traffic, in this case, Sheng Xia business will be gone back to source node routing again by the signaling batch processing.
