Abstract

Systems, methodologies, media, and other embodiments associated with prioritizing network traffic are described. One exemplary method embodiment includes receiving a notice from a computer component to prioritize network traffic associated with a selected service. Network communications are inspected to identify priority network traffic associated with the selected service. Priority settings can then be dynamically reconfigured in the priority network traffic.

Claims

1. A system comprising:

an application server for executing an application that invokes a plurality of services;

service identification logic to identify network communications from a selected service from the plurality of services by;

identifying a communication socket established for the selected service; and

identifying at least a source port value assigned to the communication socket;

a priority logic configured in a communication channel between the application server and a network device where network communications to and from the application server are processed by at least the network device, the priority logic comprising;

a notice handler configured to receive a notification event from the application server where the notification event includes identification data comprising the source port value assigned to the communication socket for the selected service, where the identification data designates values associated with network communications from the selected service that are to be prioritized;

inspection logic configured to identify network communications that are associated with the selected service in the communication channel that match the identification data by at least matching the source port value to a port value in the network communications; and

reconfiguration logic configured to dynamically reconfigure priority settings in the network communications that are identified.

2. The system of claim 1 where the network communications are embodied as data packets, and where the inspection logic is configured to:

examine header information from a received data packet; and

if the header information includes a match with the identification data, the reconfiguration logic being configured to reconfigure the priority settings in the header information.

3. The system of claim 2 where the priority settings include one or more bits associated with a Type of Service (ToS) field or a Differentiated Services Code Point (DSCP) field.

4. The system of claim 1 where the reconfiguration logic is configured to cause the network device to process the network communications with a different priority after reconfiguring the priority settings of the network communications.

5. The system of claim 1 where the identification data includes data that identifies network communications associated with the application server at a service-level to differentiate between different services processed by the application server.

6. The system of claim 1 where the priority logic is embodied in a network card configured to be operably connected to a computer system.

7. The system of claim 1 where the system is a computer system.

8. The system of claim 1 where the priority logic is embodied as an independent device configured to be in communication between the application server and the network device.

9. The system of claim 1 where the system includes the network device and where the system and the network device are configured to process network data packets.

10. The system of claim 9 where the network device includes at least one of, a router, a network traffic shaper, or a node.

11. The system of claim 9 where the priority logic system is embodied within the network device.

12. A system, comprising:

an application server including at least one processor configured to process software including one or more services;

a service identification logic configured to monitor the software being processed and to identify a priority service being processed, where the service identification logic functions to identify a socket opened for the priority service and retrieves a source port value assigned to the socket opened;

the service identification logic being further configured to transmit a priority notice to a priority logic, the priority notice including identification data comprising the source sort value assigned to the socket opened that identifies network traffic associated with the priority service;

a priority logic configured to inspect network communications being transmitted from the application server and to identify network traffic associated with the priority service using the identification data based at least in part on the source port value, the priority logic further being configured to reconfigure priority settings within the identified network traffic; and

a network device operably connected to the priority logic, the network device being configured to process network communications from the application server and to process the identified network traffic using the reconfigured priority settings.

13. The system of claim 12 where the priority logic is internal to the network device;

the network device including a memory to store the identification data from the priority notice that is separately received from the network traffic; and

the priority logic identifies the network traffic associated with the priority service by comparing the stored identification data to data within the network traffic.

14. The system of claim 12 where the priority logic is operably connected in a communication channel between the application server and the network device.

15. The system of claim 12 where the network communications include data packets, and the priority logic is configured to reconfigure the priority settings associated with header information of a data packet.

16. The system of claim 12 where the network device includes at least one of:

a router, a traffic shaper or a network node.

17. A method of prioritizing network traffic at a service-level, the method comprising the steps of:

monitoring for a socket opened for a selected service, where the selected service is invoked as part of an executing application, and where at least a portion of the monitoring is performed by a processor;

identifying, by at least the processor, a source port value assigned to the socket opened;

generating, by at least the processor, identification data including at least the source port value that is associated with the selected service that is to receive priority processing;

inspecting network communications to identify network data that is associated with the selected service using the identification data by matching a source port value from the network data to the source port value from the identification data; and

in response to a network data being matched with the source port value, dynamically reconfiguring priority settings in the network data to cause the network data to be processed with a different priority by a network device.

18. The method of claim 17 where the identification data further includes at least an IP address associated with network communications generated by the selected service.

19. The method of claim 17 where the reconfiguring priority settings step includes changing one or more bits in data packet headers.

20. The method of claim 19 where the one or more bits are within one of a Type of Service field or a Differentiated Services Code Point field.

21. The method of claim 17 where the identification data is generated in a priority notice, the priority notice being generated prior to the network data from the selected service being transmitted.

22. A computer-readable medium storing executable instructions that when executed by a processor perform a method, the method comprising:

monitoring for a socket opened for a selected service, where the selected service is invoked as part of an executing application;

retrieving a source port value assigned to the socket opened;

generating identification data including at least the source port value that is associated with the selected service that is to receive priority processing;

inspecting network communications to identify network data that is associated with the selected service using the identification data by matching a source port value from the network data to the source port value from the identification data; and

means for inspecting network communications to identify network data that is associated with the selected service using the identification data by matching a source port value from the network data to the source port value from the identification data; and

means for dynamically reconfiguring priority settings in the network data to cause the network data to be processed with a different priority by a network device, where the reconfiguring is in response to a network data being matched with the source port value.
