Abstract
The present invention facilitates the forwarding of damaged packets, when the packets are carrying a certain type of content such as streaming media or other time-sensitive information where data integrity is less important than timely delivery. Once a packet is received, a determination is made as to whether the packet has been damaged. If the packet is damaged, an attempt is made to determine the type of content being carried by the packet and then a decision is made as to whether to forward the packet toward its destination or discard the packet, based on the type of content and potentially the integrity of the packet. Once a damaged packet has been discovered and a decision has been made to route the packet toward the destination terminal, the packet may be forwarded along a normal path or sent over an alternative path that is better suited for handling damaged packets.
