FACT/XML on TIPC

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..
