Abstract

See full text

A technique for establishing a shortcut Virtual Channel Connection (VCC) in a Multi-Protocol Over ATM (MPOA) system detects a packet flow, and then determines whether to establish the shortcut VCC based upon an expected MPOA server response time. Specifically, an expected MPOA server response time is determined based upon an MPOA server response time history. The expected MPOA server response time is then compared to a predetermined MPOA server response time threshold to determine whether the expected MPOA server response time is within the predetermined MPOA server response time threshold. The shortcut VCC is established if the expected MPOA server response time is within the predetermined MPOA server response time threshold. Upon establishing the shortcut VCC, the MPOA server response time history is updated to reflect an actual MPOA server response time incurred when establishing the shortcut VCC.
