I saw this mentioned in the Feb 2003 SysAdmin. http://www.spread.org/docs/spreadoverview.html Spread is a toolkit that provides a high performance messaging service that is resilient to faults across external or internal networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast and group communication support. Spread services range from reliable message passing to fully ordered messages with delivery guarantees, even in case of computer failures and network partitions. Some of the most useful services Spread provides: * Efficient and reliable message bus. * Reliable multicast from any number of senders to lots of receivers. * Scalable group services that allow thousands of active groups. * Membership services that inform each component of an application of which other components are running, and enables easy recovery when some fail. * Agreed ordering of messages to the group - all receivers receive messages sent to the group in exactly the same order. For many document or message based applications this avoids a lot of work that used to be required for the application to order messages for usability or reliability reasons. * FIFO ordering of data streams allows applications to easily add networked streaming multimedia such as video or audio without having to make changes to existing codes or libraries that expect an in-order stream with no holes because of dropped packets on the network. ... -- Karl Vogel I don't speak for the USAF or my company vogelkeat_private http://www.pobox.com/~vogelke _______________________________________________ LogAnalysis mailing list LogAnalysisat_private http://lists.shmoo.com/mailman/listinfo/loganalysis
