Effect of message latency in an ATM network on signal processing

Date Issued:
1997
Summary:
Signal processing requires a steady flow of sampled data to be able to properly manipulate the signal to get the desired output. By using Asynchronous Transfer Mode (ATM) networks, it is possible to divide signal processing amongst a number of stations where each station can be specialized to a single function. Unfortunately, most commercially available ATM Network Interface Cards (NIC) only support message mode ATM Adaptation Layer 5 (AAL5) which is unsuitable to signal processing due to the delays of having to wait for an entire message to be formed prior to sending. It is shown that by using an ATM NIC using streaming mode AAL5, where cells are sent as soon as enough data to create an ATM cell of 48 bytes, leads to better quality signal processing. It is also shown that the message latency (time it takes for a message to traverse the network) is reduced by using streaming mode AAL5.
