[0022] overview

[0023] AAL Type 2 switching relies on Virtual Channel Connections (VCCs) as the bearer for AAL Type 2 connections. VCC can be represented by permanent VCC (PVC), switched VCC (SVC) or switched PVC (also called soft PVC). This manual focuses on SVC. If soft PVC implementation is desired, a prerequisite is the ability to exchange virtual channels.

[0024] The advantage of using switched virtual channels instead of PVCs is that administrative work is significantly reduced. Operators are not forced to initially set up PVCs in the network and continuously measure traffic for the purpose of managing the latest PVC connection resources. The network dynamically and automatically establishes the required AAL Type 2 paths for traffic flowing through it.

[0025] However, mixed operations must be supported. Operators of small networks may prefer PVC solutions. Other operators may decide to use PVCs on the access side (connecting to the RNC), but support SVCs tha...

Abstract

The invention discloses a method and device for transmitting information in an ATM network path, wherein, if the capacity of the path currently used for transmitting information exceeds a threshold, at least one new path is initiated in the network to establish a path; if the path currently used for transmitting information When the capacity is lower than the threshold, path release of at least one path is initiated in the network.

Description

technical field [0001] The present invention relates to a method and apparatus for transmitting information in an asynchronous transfer mode network path. Background technique [0002] As a resource-saving variant of the ATM (Asynchronous Transfer Mode)-based switching method, AAL (Asynchronous Transfer Mode Adaptation Layer) Type 2 switching requires Virtual Channel Connections (VCC, hereinafter referred to as "AAL Type 2 Paths" or simply "Paths") ) as a carrier for AAL type 2 connections. AAL Type 2 trails can be provided as permanent trails (PVC VCCs), switched trails (SVC VCCs), or as soft PVC VCCs. The purpose of the present invention is to enable network components to establish SVC (Switched Virtual Circuit) paths in a flexible, dynamic and predictable manner according to the traffic carried by the network, and to release the SVC path when the traffic decreases. [0003] Known solutions only use PVCs as paths. There are currently no known protocol providers or publi...
