Heartbeat Failure Detector Method And Apparatus

View page
US Patent:
6728781, Apr 27, 2004
Filed:
May 12, 1999
Appl. No.:
09/310546
Inventors:
Marcos K. Aguilera - Ithaca NY
Wei Chen - Ithaca NY
Sam Toueg - Ithaca NY
Assignee:
Cornell Research Foundation, Inc. - Ithaca NY
International Classification:
G06F 15173
US Classification:
709240, 709201, 709223, 370216, 714 4, 714 38
Abstract:
The Heartbeat Failure Detector of the present invention, is a new, simple method and device that has several identical modules, and each module is attached to a processor in the system. Roughly speaking, the module of a processor x maintains a heartbeat counter for every other process. For each process y, the counter of y at x (called the heartbeat of y at x) periodically increases while y is alive and in the same network partition, and the counter stops increasing after y crashes or becomes partitioned away. Using such a device, x can solve the communication problem above by resending m only if the heartbeat of y at x increases. Note that if y is crashed (or partitioned away from x), its heartbeat at x stops almost immediately, and so x will also immediately stop sending copies of m to y.

Failure Detector With Consensus Protocol

US Patent:
6687847, Feb 3, 2004
Filed:
Apr 19, 2000
Appl. No.:
09/552136
Inventors:
Marcos K. Aguilera - Bures-sur-Yvette, FR
Wei Chen - Nashua NH
Sam Toueg - Ithaca NY
Assignee:
Cornell Research Foundation, Inc. - Ithaca NY
International Classification:
H02H 305
US Classification:
714 4, 714 47, 714 23, 714 15
Abstract:
New failure detector mechanisms particularly suitable for use in asynchronous distributed computing systems in which processes may crash and recover, and two crash-recovery consensus mechanisms, one requiring stable storage and the other not requiring it. Both consensus mechanisms tolerate link failures and are particularly efficient in the common runs with no failures or failure detector mistakes. Consensus is achieved in such runs within 3 time and with 4n messages, where is the maximum message delay and n is the number of processes in the system.
