TRANSCRIPT
Ericsson Canada Inc.
Background
Ericsson has built a functional prototype of FACT using XML over a reliable transport protocol: TIPC
TIPC will be included in the Carrier-Grade Linux 2.0 release and is available as open source under GPL: http://tipc.sourceforge.net
One purpose was to investigate if XML is a suitable encoding language for ForCES.
Another purpose was to demonstrate the feasibility of TIPC as a base protocol for ForCES both during pre-association and post-association phases.

TIPC
Logical addressing scheme providing full location transparency
Subscription of availability/non-availability of services/nodes
Agile Connections
Easily Portable
Runs on different interconnect technologies: Raw Ethernet, ATM/AAL5,PCI,UDP,TCP,SCTP…..
