Method for recoverable message exchange independent of network protocols

摘要

A method is described to allow a device to retrieve a message, that is separated into a plurality of fragments, from a data source, wherein the method involves: establishing a first network connection with the data source; receiving a subset of the plurality of fragments; determining the first network connection has ended before completion of said message; establishing one or more subsequent network connections with the data source; and receiving any of the plurality of fragments not within the subset. The characteristics (for example: application protocol, security, speed, reach, bandwidth capability, cost of usage, network type, physical layer type, data-link layer type, or IP address of one or both of the first and second devices) of the first network connection can be potentially different than the subsequent network connections.

1. A method for a device to retrieve a message from a data source, the method comprising the steps of:
establishing a first network connection with the data source, wherein the message is separated into a plurality of fragments, and wherein a stamp that is associated with a rule is assigned to the plurality of fragments; sending, to the device retrieving the message, the stamp associated with the plurality of fragments independently of the plurality of fragments; and sending, to the device retrieving the message over the first network connection, a subset of the plurality of fragments in accordance with one or more assigned stamps and subsequent to a determination, by the device retrieving the message, to retrieve the plurality of fragments based on the one or more assigned stamps.
