Abstract

A method and apparatus for intelligent network resource manager for distributed computing systems is provided. A first priority is assigned to a first virtual channel set that includes at least two virtual channels of a plurality of virtual channels associated with a physical communication channel. A second priority is assigned to a second virtual channel set that includes at least one virtual channel of the plurality of virtual channels. The first virtual channel set has more virtual channels than the second virtual channel set. Outbound messages of the first priority are directed to virtual channels of the first virtual channel set. Outbound messages of the second priority are directed to virtual channels of the second virtual channel set. The virtual channels are processed in a round-robin order, where processing includes sending the outbound messages over the physical communication channel.

Claims

1. A method comprising:

assigning a selected priority and a selected category to each of a plurality of virtual channels selected from a set of virtual channels associated with a physical communication channel;

wherein each selected priority is selected from a plurality of priorities comprising a first priority and a second priority;

wherein each selected category is selected from a plurality of categories comprising a first category and a second category;

directing outbound messages to the plurality of virtual channels based on a category and a priority of each outbound message;

processing the plurality of virtual channels in a circular order to send the outbound messages over the physical communication channel;

wherein the method is performed by one or more computing devices.

2. The method of claim 1, wherein more virtual channels are assigned the first category than the second category.

3. The method of claim 2,

wherein the first category is a first message size category;

wherein the second category is a second message size category larger than the first message size category.

4. The method of claim 1,

wherein the outbound messages comprise database messages including redo records;

wherein redo records are associated with the first priority.

5. The method of claim 1, wherein the plurality of virtual channels or the set of virtual channels associated with the physical communication channel is processed in a round-robin order.

6. The method of claim 5, further comprising:

assigning weights to the plurality of virtual channels based on the plurality of categories and the plurality of priorities;

wherein an amount of data transmitted by a particular virtual channel during a turn is based on a weight of a particular virtual channel.

7. The method of claim 1, wherein the at least one physical communication channel comprises an InfiniBand link and the plurality of virtual channels are low-priority InfiniBand™

Virtual Lanes.

8. The method of claim 1, further comprising:

receiving configuration data specifying priority data for at least one message type;

determining the plurality of categories based at least in part on the priority data for the at least one message type.

9. A method comprising:

assigning a first priority to a first virtual channel set comprising at least two virtual channels of a plurality of virtual channels associated with a physical communication channel;

assigning a second priority to a second virtual channel set comprising at least one virtual channel of the plurality of virtual channels;

wherein the first virtual channel set has more virtual channels than the second virtual channel set;

directing outbound messages of the first priority to virtual channels of the first virtual channel set;

directing outbound messages of the second priority to virtual channels of the second virtual channel set;

processing the plurality of virtual channels in a round-robin order, wherein processing comprises sending the outbound messages over the physical communication channel;

wherein the method is performed by one or more computing devices.

10. The method of claim 9, further comprising:

assigning one of a first category and a second category to each virtual channel of the first virtual channel set;

wherein outbound messages corresponding to the first category are directed to virtual channels of the first category;

wherein outbound messages corresponding to the second category are directed to virtual channels of the second category.

11. The method of claim 9, further comprising:

assigning one of a first category and a second category to each virtual channel of the second virtual channel set;

wherein outbound messages corresponding to the first category are directed to virtual channels of the first category;

wherein outbound messages corresponding to the second category are directed to virtual channels of the second category.

12. The method of claim 11:

wherein the first category is a first message size category;

wherein the second category is a second message size category larger than the first message size category.

13. One or more non-transitory storage media storing instructions which, when executed by one or more computing devices, cause performance of:

assigning a selected priority and a selected category to each of a plurality of virtual channels selected from a set of virtual channels associated with a physical communication channel;

wherein each selected priority is selected from a plurality of priorities comprising a first priority and a second priority;

wherein each selected category is selected from a plurality of categories comprising a first category and a second category;

directing outbound messages to the plurality of virtual channels based on a category and a priority of each outbound message;

processing the plurality of virtual channels in a circular order to send the outbound messages over the physical communication channel.

14. The non-transitory storage media of claim 13, wherein more virtual channels are assigned the first priority than the second priority.

15. The non-transitory storage media of claim 14,

wherein the first category is a first message size category;

wherein the second category is a second message size category larger than the first message size category.

16. The non-transitory storage media of claim 13,

wherein the outbound messages comprise database messages including redo records;

wherein redo records are associated with the first priority.

17. The non-transitory storage media of claim 13, wherein the plurality of virtual channels or the set of virtual channels associated with the physical communication channel is processed in a round-robin order.

18. The non-transitory storage media of claim 17, the instructions further comprising instructions for:

assigning weights to the plurality of virtual channels based on the plurality of categories and the plurality of priorities;

wherein an amount of data transmitted by a particular virtual channel during a turn is based on a weight of a particular virtual channel.

19. The non-transitory storage media of claim 13, wherein the at least one physical communication channel comprises an InfiniBand™

link and the plurality of virtual channels are low-priority InfiniBand™

Virtual Lanes.

20. The non-transitory storage media of claim 13, the instructions further comprising instructions for:

receiving configuration data specifying priority data for at least one message type;

determining the plurality of categories based at least in part on the priority data for the at least one message type.
