A method of forwarding traffic in a connectionless communications network from a source location to a destination location. The traffic is associated with a predetermined category of transmission service. The method involves assigning a principal path to the traffic. The principal path operatively connects the source and destination locations. The principal path is determined on the basis that transmission of the traffic from the source location to the destination location does not exceed a specified maximum delay for transmission. An alternate path is also assigned to the traffic. The alternate path is selected on the basis that the alternate path does not exceed a specified maximum delay for involving the alternate path in order to forward the traffic along the alternate path in the event the principal path is unavailable for forwarding the traffic.
