In accordance with the invention, a system and method for providing QoS to packets formatted in accordance with one protocol (e.g., IP or Ethernet) carried over networks that are originally designed to be used with another protocol (e.g., ATM, WDM, or TDM). In one embodiment of the invention, such a switch is modified in order to allow the switch to become “IP-aware.” Such a modified switch can identify IP packets, determine if any packets should be dropped, classify the packets with a queue, and schedule the packets of each queue in a manner that provides quality of service to the packets in the queue. Moreover, some embodiments of a modified switch further include a monitor to keep statistics on the packets in the modified switch, a protection mechanism that monitors fault information for at least part of the network, and a provisioning mechanism that determines normal and backup paths for each connection.
