1. A method for managing communication protocol in a network comprising:
- receiving a message that uses a message protocol;
determining whether protocol rule should be applied to the message based on the protocol associated with the message;
when it is determined that a protocol adaptation rule should be applied to the message, then applying the appropriate protocol rule.

Abstract
A protocol management system is capable of detecting certain message protocols and applying policy rules to the detected message protocols that prevent intrusion, or abuse, of a network'"'"'s resources. In one aspect, a protocol message gateway is configured to apply policy rules to high level message protocols, such as those that reside at layer 7 of the ISO protocol stack.

31. A protocol message gateway, comprising:
-
a network interface configured to interface the protocol message gateway with a network;
a policy enforcer configured to apply a policy rule; and
a gateway manager coupled the network interface, the gateway manager configured to receive a message comprising a message protocol, determine whether a policy rule should be applied to the message based on the protocol associated with the message, and when it is determined that a policy rule should be applied to the message, then forwarding the message to the policy enforcer. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 50, 51, 52, 53)
