US 2007/0165549 A1 · Transport systems and methods incorporating absolute time references and selective buildout delays

Abstract

In various exemplary embodiments, the present invention provides transport systems and methods incorporating absolute time references, such as global positioning system (GPS) time references and/or the like, and selective buildout delays, such as first-in, first-out (FIFO) buildout delays and/or the like. In one exemplary embodiment, the transport systems and methods of the present invention are used in conjunction with the International Business Machine Corporation (IBM) Geographically-Dispersed Parallel Sysplex (GDPS) integrated, automated application and data availability solution to meet and/or exceed the associated 10 microseconds transmit/receive path differential delay requirement. Other comparable uses are also contemplated herein, as will be obvious to those of ordinary skill in the art.

Dependent claims

A network transport system, comprising:

a first server complex;
a second server complex;
wherein the first server complex is in communication with the second server complex via a transmit path and a receive path;
means for measuring a transmit/receive path differential delay associated with the transmit path and the receive path, wherein the means for measuring the transmit/receive path differential delay comprise a local clock, and wherein the local clock is in communication with an absolute time reference;
and
means for selectively compensating for the measured transmit/receive path differential delay.
