Abstract

An upstream-communication end node of an apparatus in an example upon a receipt of an indication of threshold-partial fullness of transaction-storage space on a downstream-communication end node modifies transaction-selection for delivery to the downstream-communication end node to exclude one or more transactions originated on the upstream-communication end node.

Claims

1. An apparatus, comprising:

an upstream-communication end node that upon a receipt of an indication of threshold-partial fullness of transaction-storage space on a downstream-communication end node modifies transaction-selection for delivery to the downstream-communication end node to exclude one or more transactions originated on the upstream-communication end node.

2. The apparatus of claim 1, wherein the receipt of the indication of threshold-partial fullness of transaction-storage space on the downstream-communication end node corresponds to an activation of a signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node, wherein a non-receipt of the signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node corresponds to a non-threshold fullness and/or selected-sufficiency of availability of transaction-storage space on the downstream-communication end node;

wherein the upstream-communication end node upon the activation of the signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node proceeds to;

exclude from transaction-selection for delivery to the downstream-communication end node all and/or substantially all transactions originated on the upstream-communication end node and targeted for delivery to the downstream-communication end node; and

send to the downstream-communication end node all and/or substantially all transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from one or more additional end nodes.

3. The apparatus of claim 2, wherein the upstream-communication end node upon the non-activation of the signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node proceeds to:

send to the downstream-communication end node all and/or substantially all the transactions originated on the upstream-communication end node and targeted for delivery to the downstream-communication end node; and

send to the downstream-communication end node all and/or substantially all the transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from the one or more additional end nodes.

4. The apparatus of claim 2 in combination with the downstream-communication end node, wherein the downstream-communication end node determines an activation or a non-activation of the signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node, wherein the upstream-communication end node is coupled with the downstream-communication end node for a receipt of the activation or the non-activation of the signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node.

5. The apparatus of claim 1, wherein the upstream-communication end node upon the receipt of the indication of threshold-partial fullness of transaction-storage space on the downstream-communication end node proceeds to send to the downstream-communication end node only all and/or substantially all transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from one or more additional end nodes.

6. The apparatus of claim 5, wherein the upstream-communication end node upon a non-receipt of the indication of threshold-partial fullness of transaction-storage space on the downstream-communication end node proceeds to send to the downstream-communication end node:

all and/or substantially all the transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from the one or more additional end nodes; and

all and/or substantially all transactions originated on the upstream-communication end node and targeted for delivery to the downstream-communication end node.

7. The apparatus of claim 1, wherein the upstream-communication end node and the downstream-communication end node are each capable of serving as a final destination of a transaction if the transaction is targeted thereto.

8. The apparatus of claim 1, wherein the upstream-communication end node and the downstream-communication end node each conform to a constraint that all and/or substantially all transactions originated therefrom are to traverse at most a limited number of hops of end nodes to reach a targeted destination.

9. The apparatus of claim 8, wherein the upstream-communication end node and the downstream-communication end node each conform to a constraint that all transactions originated therefrom are to traverse at most two hops of end nodes to reach a targeted destination.

10. The apparatus of claim 8, wherein each end node counted under the constraint is capable of serving as a final destination of a transaction if the transaction is targeted thereto.

11. The apparatus of claim 1 in combination with the downstream-communication end node, the apparatus further comprising a plurality of end nodes that comprises the upstream-communication end node, the downstream-communication end node, and one or more additional end nodes;

wherein only one end node of the plurality of end nodes conforms to a constraint that all and/or substantially all transactions originated therefrom are to traverse at most a limited number of hops of end nodes to reach a targeted destination.

12. The apparatus of claim 1 in combination with the downstream-communication end node, the apparatus further comprising a plurality of end nodes that comprises the upstream-communication end node, the downstream-communication end node, and one or more additional end nodes;

wherein a subset of end nodes of the plurality of end nodes conforms to a constraint that all and/or substantially all transactions originated therefrom are to traverse at most a limited number of hops of end nodes to reach a targeted destination.

13. A method, comprising the step of:

making a determination that transaction-storage space of a downstream-communication end node has reached a threshold-partial fullness; and

communicating an indication of the threshold-partial fullness to an upstream-communication end node contemporaneous with continuation of acceptance of one or more additional transactions at the downstream-communication end node.

14. The method of claim 13, wherein the step of making the determination comprises the step of:

making a determination that transaction-storage space of the downstream-communication end node has reached a threshold-partial fullness that will accommodate a delay time in communication, processing, employment, and/or interpretation of the indication of the threshold-partial fullness to, by, and/or at the upstream-communication end node through allowance of sufficient and/or extra room and/or space for one or more of the one or more additional transactions in the transaction-storage space of the downstream-communication end node upon communication of the indication of the threshold-partial fullness to the upstream-communication end node.

15. The method of claim 13, wherein the step of communicating the indication of the threshold-partial fullness comprises the step of:

communicating the indication of the threshold-partial fullness to the upstream-communication end node as an alert that the transaction-storage space of the downstream-communication end node is sufficiently occupied that the upstream-communication end node should modify transaction-sending from the upstream-communication end node to the downstream-communication end node to avoid a need to entirely stop the transaction-sending from the upstream-communication end node to the downstream-communication end node.

16. The method of claim 13, wherein the step of communicating the indication of the threshold-partial fullness comprises the step of:

activating a signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node to cause the upstream-communication end node to;

exclude from transaction-selection for delivery to the downstream-communication end node all and/or substantially all transactions originated on the upstream-communication end node and targeted for delivery to the downstream-communication end node; and

send to the downstream-communication end node as the one or more additional transactions all and/or substantially all transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from one or more additional end nodes.

17. The method of claim 16, further comprising the steps of:

making a determination that transaction-storage space of the downstream-communication end node does not reach the threshold-partial fullness; and

deactivating the signal of threshold-partial fullness of transaction-storage space on the downstream-communication end node to cause the upstream-communication end node to;

send to the downstream-communication end node all and/or substantially all the transactions originated on the upstream-communication end node and targeted for delivery to the downstream-communication end node; and

send to the downstream-communication end node all and/or substantially all the transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from the one or more additional end nodes.

18. A method, comprising the step of:

sending from an upstream-communication end node to a downstream-communication end node, contemporaneous with and notwithstanding receipt of an indication of threshold-partial fullness of transaction-storage space of the downstream-communication end node, one or more transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from one or more additional end nodes.

19. The method of claim 18, wherein the step of sending comprises the step of:

giving exclusive preference upon receipt of the indication of threshold-partial fullness of transaction-storage space of the downstream-communication end node, to the one or more transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from one or more additional end nodes, over one or more transactions originated on the upstream-communication end node and targeted for delivery to the downstream-communication end node.

20. The method of claim 19, further comprising the step of:

sending from the upstream-communication end node to the downstream-communication end node contemporaneous with receipt of an indication of an unmet threshold-partial fullness of transaction-storage space of the downstream-communication end node;

one or more additional transactions targeted for delivery to the downstream-communication end node and received by the upstream-communication end node from the one or more additional end nodes; and

the one or more transactions originated on the upstream-communication end node and targeted for delivery to the downstream-communication end node.
