Abstract

During several previous SATNET meetings, it has been observed that it would be useful for BBN to be able to access the European side of SATNET indirectly via the VAN Gateway, when direct SATNET connectivity has been lost. This short paper proposes a possible approach to such "backup" access, using the source routing option of IP.

Backup Access to the European Side of SATNET

Robert Braden

DISCUSSION

The purpose of this RFC is to focus discussion on a

particular Internet problem: a backup path for software

maintenance of the European sector of the Internet, for

use when SATNET is partitioned. We propose a

mechanism, based upon the Source Routing option of IP,

to reach European Internet sites via the VAN Gateway

and UCL.

This proposal is not intended as a standard at this

time.

1. Introduction

During several previous SATNET meetings, it has been

observed that it would be useful for BBN to be able to

access the European side of SATNET indirectly via the VAN

Gateway, when direct SATNET connectivity has been lost.

This short paper proposes a possible approach to such

"backup" access, using the source routing option of IP.

Figure 1 illustrates the problem we wish to solve. The US

host H is used for diagnosis and control of the SATNET

SIMP's S1 and S2 as well as the gateways B and G and the UCL

TAC (not shown, but connected to G).
