Abstract

Apparatus, systems, and methods to manage networks may operate to receive a packet into an element of an array contained in a memory while a low resource state exists, and to truncate the array at the element responsive to at least one of an indication that the array is full, or an indication that no more packets are available to be received after receiving at least the packet. The receiving and the truncating may be executed by a processor. Additional apparatus, systems, and methods are disclosed.

Claims

1. An apparatus, comprising:

memory having a plurality of memory elements to store packets of data;

a processor, coupled to the memory, to receive packets of data and to provide the received packets of data to the memory elements to construct an array; and

an array truncation module, coupled to the processor, to truncate the array at one of the plurality of memory elements, responsive to an indication of completion of construction of the array upon determination of one of the array being full or that no more packets are available for reception after at least one packet has been received into one of the plurality of memory elements.

2. The apparatus of claim 1,

wherein the memory includes a packet-receiving module.

3. The apparatus of claim 1, wherein the memory further includes an array indication module to indicate the array responsive to an indication that the array truncation module has truncated the array.

4. A receiving node, comprising:

memory having a plurality of memory elements to store packets of data;

a processor, coupled to the memory, to receive packets of data and to provide the received packets of data to the memory elements to construct an array;

a packet-receiving module, coupled to the processor, to receive a packet from a sending node into one of the memory elements of the array responsive to an indication of an existing low resource state;

an array truncation module, coupled to the processor, to truncate the array at one of the plurality of memory elements responsive to an indication of completion of construction of the array upon determination of one of the array being full or that no more packets are available for reception after at least the packet has been received into the one of the plurality of memory elements; and

an array indication module, coupled to the processor, to indicate the array responsive to an indication that the array truncation module has truncated the array.

5. The node of claim 4, further comprising:

a low resource module to store a representation of the low resource state and a representation of a resource state associated with reception of another packet into an additional element of the array.

6. The node of claim 4, wherein the receiving node is capable of receiving the packet from at least one of a wide area network or a local area network.

7. The node of claim 4, wherein the packet-receiving module operates accordance with a network driver interface specification.

8. The node of claim 4, further comprising:

a low resource module coupled to the packet-receiving module, the low resource module to provide the indication of the existing the low resource state.

9. The node of claim 8, wherein the low resource module comprises a desterilized driver module.

10. A method, comprising:

providing memory having a plurality of memory elements to store packets of data

receiving packets of data and providing the received packets of data to the memory elements to construct an array while a low resource state exists; and

truncating the array at one of the plurality of the memory elements determined to be the memory element where the low resource state occurs, the receiving and the truncating to be executed by the processor.

11. The method of claim 10, further comprising:

determining that the array is full or that no more packets are available to be received.

12. The method of claim 10, further comprising:

indicating when the array is full and resources are not low, or when the array is full and no more packets are available to be received.

13. The method of claim 10, wherein receiving the packet into one of the plurality of memory elements occurs in accordance with a network driver interface specification.

14. The method of claim 10, further comprising:

determining when another packet remains in the array after the truncating.

15. The method of claim 10, further comprising:

determining the memory element of the array to truncate the array at by calculating an index.

16. The method of claim 15, further comprising:

calculating the index by subtracting a difference between a low resource threshold associated with the array and a number of resources remaining when the packet was received into the memory element of the array.

17. The method of claim 10, further comprising:

associating a first memory element of the array with another packet included in a next element of the array following the packet received into the memory element of the array.

18. The method of claim 10, further comprising:

determining a truncation location in the array after construction of the array completes.

19. The method of claim 10, further comprising:

terminating construction of the array when the array is full or when no more packets are available for reception.

20. The method of claim 10, further comprising:

indicating the array after the truncating as a truncated array; and

subsequently indicating memory elements included in the truncated array.
