US 8,805,944 B2 · Transport high availability via acknowledge management

Abstract

Architecture that facilitates transport high availability for messaging services by providing the ability of a receiving entity (e.g., receiving message transfer agent (MTA)) to detect if a sending entity (e.g., sending MTA or client) is a legacy sending entity. When the receiving entity detects that the sending entity is a legacy system, by advertising transport high availability capability to the sending entity, if the sending entity does not opt-in to this capability, the receiving entity keeps the sending entity client “on hold”, that is, waiting for an acknowledgement (ACK) until the receiving entity delivers the message to the next hops (immediate destinations). This approach maintains at least two copies of the message until the message is successfully delivered (to the next hop(s)). Hence, if the legacy sending entity or the receiving entity fails, the message is still delivered successfully.

Dependent claims

A computer-readable storage drive including instructions, that when executed by a computing device, cause the computing device to:

detect capability information of a sending entity from which a message is received at a receiving entity, the capability information indicating whether the sending entity is a legacy sending entity;
delay transmission of an acknowledgement message from the receiving entity to the sending entity based on the capability information, wherein indicating to the sending entity that the sending entity may delete the sending entity's copy of the message is delayed until successful delivery of the message from the receiving entity to a next receiving entity;
and
store the delayed acknowledgement message at the receiving entity until an acknowledgement is received from the sending entity that the delayed acknowledgement message was received.

1 more element

A computer-implemented messaging system, comprising:

a detection component of a receiving entity for detecting capability information of a sending entity from which a side-effect message, generated by a messaging server when processing a message, has been received at the receiving entity, the capability information indicating whether the sending entity is a legacy sending entity;
a delay component for delaying transmission of an acknowledgement from the receiving entity to the sending entity based on the capability information, wherein the delay component delays indicating to the sending entity that the sending entity may delete the sending entity's copy of the side-effect message until the side-effect message is delivered successfully by the receiving entity to a next receiving entity;
and
a processor implementing one or both of the detection component and the delay component.
