Abstract
Abstract A system and method of translating a set of transmission parameters related to a first transmission protocol from said first transmission protocol to a second transmission protocol for a data element being sent on a connection from a first communication network utilizing the first transmission protocol to a second communication network utilizing the second transmission protocol is provided. The method includes mapping a first parameter from the set of transmission parameters to a class of service value for the connection and mapping the class of service value and a second parameter from the set of transmission parameters to another parameter for the second transmission protocol.
