- 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.
