Abstract

In this paper a new method for distributing and updating host name/address information in large computer networks is described. The technique uses datagrams to provide a simple transaction-based query/response service. A provisional service is being provided by the Arpanet Network Information Center (NIC) and is used by mobile packet radio terminals, as well as by several Arpanet DEC-10 hosts. Extensions to the service are suggested that would expand the query functionality to allow more flexible query formats as well as queries for service addresses. Several architectural approaches with potential for expansion into a distributed internet environment are proposed. This technique may be utilized in support of other distributed applications such as user identification and group distribution for computer based mail.

Abstract

In this paper a new method for distributing and updating host

name/address information in large computer networks is described.

The technique uses datagrams to provide a simple

transaction-based query/response service. A provisional service

is being provided by the Arpanet Network Information Center (NIC)

and is used by mobile packet radio terminals, as well as by

several Arpanet DEC-10 hosts. Extensions to the service are

suggested that would expand the query functionality to allow more

flexible query formats as well as queries for service addresses.

Several architectural approaches with potential for expansion

into a distributed internet environment are proposed. This

technique may be utilized in support of other distributed

applications such as user identification and group distribution

for computer based mail.

1. INTRODUCTION

In large computer networks, such as the Arpanet [1],

network-wide standard host-addressing information must be

maintained and distributed. To fulfill that need, the Arpanet

Network Information Center (NIC) at SRI International has

maintained, administered, and distributed the host addressing

data base to Arpanet hosts since 1972 [2].

The most common method for maintaining an up-to-date copy on

each host is to bulk-transfer the entire data base to each host

individually. This technique satisfies most host addressing

needs on the Arpanet today. However, some hosts maintain neither

a complete nor a current copy of the data base because of limited

memory capacity and infrequent processing of updates. In

addition, with the expansion of the Arpanet into the internet

environment [3, 4], a strong need has arisen for new techniques

to augment the distribution of name/address information.

One method currently being investigated is the dynamic

distribution of host-address information via a transaction-based,

inquiry-response process called the Name Server [5, 6]. To

support this investigation, the NIC has developed a provisional

Name Server that...
