Miru Announces OpenPGM 5

New York - September 6, 2010 - Miru, Limited, a small development studio of enterprise middleware, announces a new BSD socket interface for its OpenPGM messaging software, an open source low latency reliable multicast solution based on the standard for broadcasting information over an internet.  The Berkeley sockets API is the defacto standard for abstraction of network sockets and so reduces the learning curve necessary to implement new solutions using OpenPGM.

Performance for one-way messaging of roughly 75 to 80 microseconds with throughput of approximately 540 megabits per second to applications running on a single core commodity system.
The transport technology standard, known as Pragmatic General Multicast, enables private networks and the Internet to handle more traffic by sending critical business information in a more reliable, cost-effective and bandwidth-friendly manner.

The PGM reliable transport protocol communications technology, which was designed by Cisco Systems and TIBCO Software, is registered with the Internet Engineering Task Force (IETF), the Internet standards body.

PGM enabled network devices, such as Cisco, Juniper, or Nortel routers, enhance the scalability and reliability of the technology by eliminating redundant traffic when recovering lost messages.

The updated transport is supported on Linux and Solaris platforms on IA32, x86-64, SPARCv9 architectures, with other platforms and architectures such as Microsoft Windows and Mac OS X with functional builds but support added as customer needs dictate.  OpenPGM is Wire compatible with Microsoft’s PGM implementation as available in Microsoft Windows Server 2003 and Microsoft Windows XP with Microsoft Message Queuing.

About IP Multicast

In computer networking, broadcast refers to transmitting a message to every device on the network, a one-to-many paradigm similar to television or radio. Multicast is a technique to only deliver to those recipients expressing an interest in the content. A multicast source is only required to send a message once, the network infrastructure takes care of replicating to each receiver as necessary. Conventional unicast applications require the server to send copies of the same message to each recipient.

Multicast does not guarantee reliability or ordering of messages. A recipient may receive messages out of order, duplicated, or missing with no notice.

About Pragmatic General Multicast (PGM)

PGM is a reliable multicast transport protocol developed by a range of vendors including Cisco and TIBCO and described in RFC 3208.
