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 within a switched fabric;

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, wherein the first category is based on a first message size and the second category is based on a second message size that is larger than the first message size, wherein more virtual channels are assigned the first category than the second category;

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

segmenting each outbound message into one or more respective packets to generate a plurality of packets that each do not exceed a maximum packet size, wherein said second message size exceeds said maximum packet size;

processing the plurality of virtual channels in a circular order to send a same amount of packets from said plurality of packets for each virtual channel over the physical communication channel within the switched fabric;

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

2. The method of claim 1,

wherein the outbound messages comprise database messages including redo records;

wherein redo records are associated with the first priority.

3. The method of claim 2, wherein the redo records comprise at least one data block.

4. The method of claim 2, wherein the redo records comprise at least one control message.

5. The method of claim 2, wherein:

the plurality of priorities contains a third priority;

the outbound messages comprise additional messages that do not contain redo records;

the additional messages comprise control messages that are associated with the second priority and data blocks that are associated with the third priority.

6. The method of claim 5, wherein:

the additional messages comprise small messages that contain a respective single data block;

the small messages are associated with the second priority.

7. The method of claim 1, wherein 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 within a switched fabric;

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;

assigning one of a first category that is based on a first message size and a second category that is based on a second message size to each virtual channel of at least one virtual channel set of;

the first virtual channel set or the second virtual channel set, wherein the first message size is smaller than the second message size, wherein more virtual channels are assigned the first category than the second category;

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;

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;

segmenting each outbound message into one or more respective packets to generate a plurality of packets that each do not exceed a maximum packet size, wherein said second message size exceeds said maximum packet size;

processing the plurality of virtual channels in a round-robin order, wherein processing comprises sending a same amount of packets from said plurality of packets for each virtual channel over the physical communication channel within the switched fabric;

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

10. One or more non-transitory computer-readable media storing instructions which, when executed by one or more computing devices, cause:

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 within a switched fabric;

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, wherein the first category is based on a first message size and the second category is based on a second message size that is larger than the first message size, wherein more virtual channels are assigned the first category than the second category;

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

segmenting each outbound message into one or more respective packets to generate a plurality of packets that each do not exceed a maximum packet size, wherein said second message size exceeds said maximum packet size;

processing the plurality of virtual channels in a circular order to send a same amount of packets from said plurality of packets for each virtual channel over the physical communication channel within the switched fabric.

11. The one or more non-transitory computer-readable media of claim 10,

wherein the outbound messages comprise database messages including redo records;

wherein redo records are associated with the first priority.

12. The one or more non-transitory computer-readable media of claim 11, wherein the redo records comprise at least one data block.

13. The one or more non-transitory computer-readable media of claim 11, wherein the redo records comprise at least one control message.

14. The one or more non-transitory computer-readable media of claim 11, wherein:

the plurality of priorities contains a third priority;

the outbound messages comprise additional messages that do not contain redo records;

the additional messages comprise control messages that are associated with the second priority and data blocks that are associated with the third priority.

15. The one or more non-transitory computer-readable media of claim 14, wherein:

the additional messages comprise small messages that contain a respective single data block;

the small messages are associated with the second priority.

16. The one or more non-transitory computer-readable media of claim 10, wherein at least one physical communication channel comprises an InfiniBand™

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

Virtual Lanes.

17. The one or more non-transitory computer-readable media of claim 10, 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.
