IONA Combines the Best of CORBA and Multicast Messaging in OrbixTalk

OrbixTalk implements OMG Events Service

Object World, Boston, MA., May 8th 1996: IONA Technologies has unveiled
OrbixTalk as the first implementation of the CORBA Events Services.
OrbixTalk combines the best of standards-based distributed object
technology with message-oriented middleware. IONA also announced a
powerful extension to the OrbixTalk product here today codenamed
TalkStore.

OrbixTalk is a scalable messaging system which builds on IONA Technologies'
market leading Orbix product line. OrbixTalk implements a powerful and
flexible events paradigm, which enables reliable de-coupled messaging
between objects in a distributed system. TalkStore adds the reliability of
full persistence and playback facilities.

"The de-coupled interaction provided in OrbixTalk enables our customers to
build component-based, collaborative applications to any scale. OrbixTalk
is faithful to the CORBAservices Events standard, and works with IONA's
Orbix object request broker, guaranteeing future-proofing for large-scale
enterprise distributed applications," says Annrai O'Toole, chief
technology officer at IONA Technologies.

Scalability is ensured by the asynchronous nature of the OrbixTalk
architecture which means clients and servers are not locked into a single,
exclusive dialog. IONA Technologies has extended the asynchronous model of
the Events CORBAservice specification with persistence and multicast
functionality.

OrbixTalk enables applications to share data using a fast and convenient
communications mechanism based on the UDP/IP (User Data Protocol/Internet
Protocol) Multicast standard. IONA has improved the reliability of UDP
Multicast with the OrbixTalk Reliable Multicast Protocol (OTRMP), which
ensures messages are reliably delivered to all listening applications in
the correct sequence.

TalkStore plays an important role in providing guaranteed persistence by
ensuring server messages are delivered to OrbixTalk clients even if the
client or server fails.

"OrbixTalk has been put through an extensive beta test programme in more
than 60 corporations around the world. Feedback has been very positive
with customers using the product in a wide variety of applications," says
O'Toole.
