Applying quality of service to application messages in network elements
First Claim
1. A data processing apparatus, comprising:
- a plurality of network interfaces that are coupled to a data network for receiving one or more packets therefrom and sending one or more packets thereto;
one or more processors;
a switching system coupled to the one or more processors and packet forwarding logic, wherein the switching system and packet forwarding logic are configured to receive packets on a first network interface, determine a second network interface on which to send the packets, and to send the packets on the second network interface;
a computer-readable storage medium recorded with one or more message classification rules and a mapping of message classification values to network-level QoS values, wherein each of the message classification rules specifies one or more message attributes and one of the message classification values;
application QoS logic which when executed by the one or more processors is operable to cause;
receiving an application-layer message;
matching one or more attributes of the application-layer message to the message classification rules;
determining a message classification of the application-layer message based on the matching;
selecting one of the network-level QoS values using the mapping and based on the determined message classification;
marking a network-level header of the application-layer message using the selected QoS value.

Abstract
A network element such as a router or switch provides application-level quality of service for application-layer messages processed in the network element, using application QoS logic which when executed by the one or more processors is operable to cause receiving an application-layer message; matching one or more attributes of the application-layer message to the message classification rules; determining a message classification of the application-layer message based on the matching; selecting one of the network-level QoS values using the mapping and based on the determined message classification; and marking a network-level header of the application-layer message using the selected QoS value. As a result, attributes of application messages at OSI Layer 5, 6, or 7 can be used to determine how to mark packets of the messages with QoS values at OSI Layer 2, 3 or 4, integrating application-level concepts of order and priority into network-layer QoS mechanisms.
