Abstract
A method for adjusting an ATM switch local service policy based on a non-ATM protocol service parameter, the method including the steps of inspecting the payload of an ATM PDU received at a switch along at least one VCC to identify a non-ATM PDU protocol identifier included in the payload, inspecting the payload to identify a non-ATM PDU service identifier associated with the non-ATM PDU protocol identifier, and selectively adjusting a local service policy attribute within the switch for the at least one VCC based on the non-ATM PDU service identifier in accordance with an adjustment value previously associated with the non-ATM PDU protocol identifier and the non-ATM PDU service identifier.

A method for adjusting an ATM switch local service policy based on a non-ATM protocol service parameter, the method comprising the steps of:
- a) inspecting the payload of an ATM PDU received at a switch along at least one VCC to identify a non-ATM PDU protocol identifier included in said payload;
- b) inspecting said payload to identify a non-ATM PDU service identifier associated with said non-ATM PDU protocol identifier;
- and
- c) selectively adjusting a local service policy attribute within said switch for said at least one VCC based on said non-ATM PDU service identifier in accordance with an adjustment value in predefined association with said non-ATM PDU protocol identifier and said non-ATM PDU service identifier.
Apparatus for adjusting an ATM switch local service policy based on a non-ATM protocol service parameter comprising:
- means for inspecting the payload of an ATM PDU received at a switch along at least one VCC to identify a non-ATM PDU protocol identifier included in said payload;
- means for inspecting said payload to identify a non-ATM PDU service identifier associated with said non-ATM PDU protocol identifier;
- and
- means for selectively adjusting a local service policy attribute within said switch for said at least one VCC based on said non-ATM PDU service identifier in accordance with an adjustment value in predefined association with said non-ATM PDU protocol identifier and said non-ATM PDU service identifier.
