Description of Working Group:
The DoD INTERNET TCP/IP protocol suite has developed into a de facto
industry standard for heterogenous packet switching computer networks.
In the US, several hundreds of INTERNET networks are connected
together; however the situation is completely different in Europe.
\vspace{.15in}
The only network which could be used as a backbone to allow
interoperation between the many local area networks in Europe, now
subscribing to the DoD INTERNET TCP/IP protocol suite, would be the
system of Public Data Networks (PDN). However, so far, no algorithms
have been provided to dynamically route INTERNET datagrams through
X.25 public data networks. Therefore, the goals of the Public Data
Network Routing Working Group are the development, definition and
specification of required routing and gateway algorithms for an
improved routing of INTERNET datagrams through the system of X.25
Public Data Networks (PDN) to allow worldwide interoperation between
TCP/IP networks in various countries. In addition, the application
and/or modification of the developed algorithms to interconnect local
TCP/IP networks via ISDN (Integrated Services Digital Network) will be
considered.
Goals and Milestones:
Done Application of the INTERNET Cluster Addressing Scheme to Public Data
Networks.
Done Development of hierarchical VAN-gateway algorithms for worldwide
INTERNET network reachability information exchange between
VAN-gateways.
Done Assignment of INTERNET/PDN-cluster network numbers to national public
data networks. (Mapping between INTERNET network numbers and X.121
Data Network Identification Codes (DNICs)).
Done Assignment of INTERNET/PDN-cluster addresses to PDN-hosts and
VAN-gateways according to the developed hierarchical VAN-gateway
algorithms.
Done Definition of the PDN-cluster addressing scheme as an Internet
standard.
Done Delayed TCP/IP header compression by VAN-gateways and PDN-hosts.
Done Provide a testbed for worldwide interoperability between local TCP/IP
networks via the system of X.25 public data networks (PDN).
Done Implementation of the required algorithms and protocols in a VAN-Box.
Done Interoperability between ISO/OSI hosts on TCP/IP networks through
PDN.
Done Consideration of INTERNET Route Servers.
Done Interoperability between local TCP/IP networks via ISDN.
Done Development of Internetwork Management Protocols for worldwide
cooperation and coordination of network control and network
information centers.
Done Specification of an X.121 Address resolution protocol.
Done Specification of an X.25 Call Setup and Charging Determination
Protocol.
Done Specification of an X.25 Access and Forwarding Control Scheme.
Done Specification of routing metrics taking X.25 charges into account.
