Abstract

A non-transitory computer readable medium is provided comprising: code for use by a client node including one or more processors in communication with a non-transitory memory, where the code, when used by the client node, causes the client node to: receive, by the client node from a server node, a transmission control protocol (TCP)-variant packet; detect an idle time period parameter field in the TCP-variant packet; identify metadata in the idle time period parameter field for an idle time period that is detectable by the server node and, during which, no packet is communicated in the TCP-variant connection to keep the TCP-variant connection active; and modify, by the client node and based on the metadata, a timeout attribute associated with the TCP-variant connection.

Claims

1. A non-transitory computer readable medium, comprising:

code for use by a client node including one or more processors in communication with a non-transitory memory, where the code, when used by the client node, causes the client node to;

receive, by the client node from a server node, a transmission control protocol (TCP)-variant packet;

detect an idle time period parameter field in the TCP-variant packet;

identify metadata in the idle time period parameter field for an idle time period, during which, no packet is communicated in a TCP-variant connection to keep the TCP-variant connection active; and

modify, by the client node and based on the metadata, a timeout attribute associated with the TCP-variant connection.

2. The non-transitory computer readable medium of claim 1 wherein the timeout attribute is an attribute of a keep-alive.

3. The non-transitory computer readable medium of claim 1 wherein the code, when used by the client node, causes the client node to operate such that the receiving is performed subsequent to sending, by the client node to the server node, another TCP-variant packet including other metadata including an idle time period parameter.

4. The non-transitory computer readable medium of claim 3 wherein the metadata is the same as the other metadata.

5. The non-transitory computer readable medium of claim 3 wherein the metadata is different from the other metadata.

6. The non-transitory computer readable medium of claim 1 wherein the timeout attribute is specified in a number of seconds.

7. The non-transitory computer readable medium of claim 1 wherein the code, when used by the client node, causes the client node to operate such that the timeout attribute is used to keep the TCP-variant connection open when inactive, and to prevent the server node from closing the TCP-variant connection when inactive.

8. The non-transitory computer readable medium of claim 1 wherein the code, when used by the client node, causes the client node to operate such that the metadata is used as input of an algorithm for determining a duration of time specified by the timeout attribute.

9. The non-transitory computer readable medium of claim 8 wherein the code, when used by the client node, causes the client node to operate such that the algorithm is determined based on at least one particular attribute.

10. The non-transitory computer readable medium of claim 1 wherein the code, when used by the client node, causes the client node to operate such that the modification of the timeout attribute results from a negotiation between the server node and the client node via a negotiation protocol of a TCP-variant protocol.

11. The non-transitory computer readable medium of claim 1 wherein the code, when used by the client node, causes the client node to:

detect the idle time period based on the timeout attribute; and

22. A system including the non-transitory computer readable medium of claim 16, wherein the system:

includes another server node separate from the server node, is configured to communicate the code to the client node for use in establishing the TCP-variant connection with the server node, and is further configured to perform a 3-way TCP handshake for establishing, with the client node, a TCP connection that is different than the TCP-variant connection for permitting the client node to fetch the code in addition to other data from the system via a hypertext transfer protocol (HTTP).

23. The system of claim 22, wherein the code, when used by the client node, results in the client node operating such that the TCP-variant connection is established between the client node and the server node instead of the TCP connection in order to permit communication, between the client node and the server node, of the timeout attribute, where the timeout attribute is not communicated when establishing the TCP connection between the system and the client node, but is communicated when establishing the TCP-variant connection between the client and the server node.
