Embodiment Construction

[0018] The invention mainly provides automatic configuration of ATM services. The service automatic configuration method described in the present invention is divided into following three steps:

[0019] Routing options:

[0020] The number of services in a general network is determined in units of rings or chains. For example, for two-fiber unidirectional multiplex section protection, in the case of STM-1, the total number of services in a ring is 63 time slots. Therefore, when determining routing and analyzing time slots, rings or chains are considered as units. At the same time, for the convenience of description, when analyzing the problem, unless otherwise specified, the network element connection only takes the ring as the object, and in the case of protection, the two-fiber unidirectional multiplex section is used as the object.

[0021] Before routing is determined, the network elements and network topology in the network are preprocessed first. Place the network el...

Abstract

The invention provides a method of automatic configuration for asynchronous transmission mode business, including: firstly determining the loop, loop number and crossing point between loops comprising origin network and target network, determining specific network by segment according to the connecting condition of the network, recording the network on the service route; recording time slot occupation of respective network in next group service, processing the time slot data having the network as unit, memorizing the necessary time slot, and transmitting the data to the correlative network by the network management when needing to start service; recording correlative network time slot branch line occupation record of the next group service and generating VPC correlative record when determining the service and transmitting the data to correlative network by network management when needing to start service. The users can finally determine the configuration of the service by the invention that facilitates the user and ensures the reliability of the data.

Description

technical field [0001] The invention relates to an end-to-end configuration method of ATM services in an ATM (Asynchronous Transfer Mode) Over Synchronous Digital System SDH (Synchronous Digital Hierarchy) optical transmission network, more specifically, an ATM under the ATM Over SDH mode An end-to-end auto-configuration method for services. Background technique [0002] ATM Over SDH uses SDH's large capacity, optical fiber transmission and stable and reliable network structure with self-healing and detour routing as the basis of ATM switching core. Its technology is to pack ATM cells into SDH frames (ATM cells are mapped to SDH VC-4 containers) for transmission on SDH, that is, to use ATM's connection-oriented fast switching capability to provide quality of service QoS guarantee; and to use SDH reliable transmission characteristics. Therefore, considering performance, price and development trend, this transmission method has been widely used in the construction of wide-ar...
