Abstract
One embodiment of the invention provides apparatus and a method for handling an incoming packet at a port in a network. The port belongs to one or more partitions, and at least one service level is associated with each of the partitions. When a packet is received at the port, a partition key and a service level are extracted from the packet. The extracted partition key is used to determine the partition to which the received packet belongs. The service level extracted from the packet is then compared against the service level(s) associated with the determined partition in order to authenticate the packet. In another embodiment, the service level is correlated against a destination identifier from the packet instead of the partition key.
