Title:
IMPROVED HANDLING OF ATM DATA
Document Type and Number:
WIPO Patent Application WO2006036124
Kind Code:
A8
Abstract:
There is provided an ATM (Asynchronous Transfer Mode) module for receiving ATM cells from a connection line providing a plurality of virtual channels and a method for the transmission of ATM data. The ATM module comprises a hardware module. Each ATM cell is assigned a virtual channel based on its higher layer QoS (Quality of Service) and the hardware module is arranged to map the channel of an ATM cell to its higher layer QoS. There is also provided a method and apparatus for reassembling AAL5 (ATM Adaptation Layer 5) messages for higher layer protocol. The method comprises the steps of providing an ATM SAR (Segmentation And Reassembly) module for receiving ATM cells across a plurality of channels; providing a processor connected to the ATM SAR module; the ATM SAR module detecting receipt of complete messages from the plurality of channels; the ATM SAR module distinguishing between low priority messages and high priority messages; for each low priority message: the processor reassembling the message via software control; and for each high priority message: the ATM SAR module reassembling the message via hardware control.
