+ Principles of Operation for the TPC.INT Subdomain:
+ General Principles and Policy
+
+Status of this Memo
+
+ This memo provides information for the Internet community. It does
+ not specify an Internet standard. Distribution of this memo is
+ unlimited.
+
+Abstract
+
+ This document defines the initial principles of operation for the
+ tpc.int subdomain, a collection of service listings accessible over
+ the Internet infrastructure through an administered namespace
+ contained within the Domain Name System [1,2].
+
+ This document is informational and applies only to those Internet
+ sites that choose to register themselves within the tpc.int
+ subdomain. The tpc.int subdomain is organized as a cooperative of
+ the sites that provide access within the context of the subdomain.
+ Policy for the subdomain is set by a board responsible to the
+ cooperative.
+
+ The primary purpose of the tpc.int subdomain is to provide
+ transparent mapping between general-purpose computers on the Internet
+ and special-purpose devices directly connected to the telephone
+ network. Initially, a remote printing service is defined [3,4] which
+ ties together G3-compatible facsimile devices on the telephone
+ network with users of electronic mail in the Internet and associated
+ message-handling domains connected to the Internet by application-
+ layer gateways.
+
+ It should be noted that remote printer gateways have long been
+ technically feasible and have become an integral part of many
+ individual networks. The tpc.int subdomain integrates individual
+ sites into a common namespace, transforming remote printing from a
+ single-site, value-added service into an integral transparent service
+ in the global Internet.

+
+
+Overview of Services in the TPC.INT Subdomain
+
+ The tpc.int subdomain is organized as a cooperative, an association
+ organized for the purpose, without gain to itself, of rendering
+ service as defined in this document and as further defined by the
+ membership of the cooperative. Members of the tpc.int subdomain
+ cooperative are defined as those Internet sites who provide access to
+ services as defined in this document and as periodically amended by
+ the membership as represented by the Board of Arbitration and
+ Conciliation for the tpc.int subdomain.
+
+ The primary purpose of the tpc.int subdomain is to provide
+ transparent mappings between users of general-purpose computers on
+ the Internet and special-purpose devices directly connected to the
+ telephone network. This mapping extends the population reachable
+ from the Internet by providing a communications path to devices not
+ otherwise directly addressable.
+
+ The initial remote printing facility is built on top of the
+ electronic mail protocols of the Internet, including RFC 822 [5] and
+ MIME [6]. Because the remote printing service uses the message-
+ handling facilities of the Internet, this service is also available
+ to message-handling domains that are connected to the Internet
+ through application-layer gateways (e.g., X.400-compatible systems
+ [7], UUCP-based message-handling environments [8], and commercial
+ services such as AT&T Mail), MCI Mail), SprintMail), and CompuServe)
+ [9]).
+
+Operation of Name Service in the TPC.INT Subdomain
+
+ Services in the Internet are identified with a service target name as
+ listed in the Domain Name System (DNS). These target names are
+ looked up in the DNS and the appropriate resource records associated
+ with the name are returned. After the name lookup has been
+ completed, the initiator exchanges a series of IP packets with an
+ Internet site which provides access to a service accessible through
+ the tpc.int subdomain.
+
+ In the case of remote printing, the DNS MX resource record is used to
+ register those Internet sites that provide access to the remote
+ printing facility. Specifically, an Internet site running a remote
+ printer server registers itself in the DNS as being willing to
+ provide access to some portion of the telephone system numbering plan
+ as registered by one or more MX records within the tpc.int subdomain.
+
+ For example, if the host hewes.radio.com is willing to provide remote
+ printing to devices with telephone numbers beginning with the prefix
+ +1-415-336, the host would be listed in the Domain Name System with
+
+
+
+Malamud & Rose [Page 2]
+
+RFC 1530 General Principles and Policy October 1993
+
+
+ the following MX resource record:
+
+ *.6.3.3.5.1.4.1.tpc.int. IN MX 10 hewes.radio.com.
+
+ Note that the resource records can have an arbitrary level of
+ precision. For example, the North American numbering plan (IDDD
+ country code 1) is structured by a 3-digit area code, followed by a
+ 3-digit exchange prefix, followed by a 4-digit station number. As
+ such, one might expect that resource records in this zone would be
+ similar to
+
+ *.5.1.4.1.tpc.int. IN MX 10 hewes.radio.com.
+
+ which accesses any printer with a telephone number prefix of +1-415
+ (i.e., any printer in area code 415). Another record might be
+ similar to
+
+ *.8.6.9.5.1.4.1.tpc.int. IN MX 10 hewes.radio.com.
+
+ allowing access to any printer in area code 415, exchange prefix 968.
+ However, the level of precision is arbitrary. For example, if all of
+ the printers in an organization had a telephone number prefix of +1-
+ 415-96, the following resource record could be used:
+
+ *.6.9.5.1.4.1.tpc.int. IN MX 10 hewes.radio.com.
+
+ It is the responsibility of administrators of the tpc.int namespace
+ to register only those Internet sites that are willing to confirm to
+ the principles of operation as defined in this document and as
+ periodically amended by the Board of Arbitration and Conciliation for
+ the tpc.int subdomain.
+
+ It is a key principle in the tpc.int subdomain that all Internet
+ sites meeting the principles of operation as stated in this document
+ shall be registered in the tpc.int subdomain without bias and that
+ the subdomain should encourage the largest number of Internet sites
+ possible.
+
+ If multiple Internet sites are willing to provide access in the same
+ area, multiple resource records for the same target name are
+ maintained. In response to a query, the Domain Name System returns
+ the resource records in an unordered list. In practice, however, the
+ initiator will consult the list in the order returned. To provide an
+ unbiased environment, an authoritative name server for the tpc.int
+ subdomain shall alternate the ordering of the list frequently, and
+ shall return a small TTL with the resource records.

+
+
+Policy Determination in the TPC.INT Subdomain
+
+ The tpc.int subdomain is organized as a cooperative, an association
+ organized for the purpose of rendering service, without gain to
+ itself, within the scope of service defined in this document and as
+ further defined by the membership of the cooperative. Members of the
+ tpc.int subdomain cooperative are defined as those Internet sites who
+ provide access to services as defined in this document and as
+ periodically amended by the membership as represented by the Board of
+ Arbitration and Conciliation for the TPC.INT Subdomain.
+
+ The primary purpose of the tpc.int subdomain is to provide
+ transparent mappings between users of general-purpose computers on
+ the Internet and special-purpose devices directly connected to the
+ telephone network. The listing of services in the tpc.int subdomain
+ is for the necessity and convenience of the general public with
+ special emphasis on providing a general-purpose link between the
+ Internet infrastructure and communications devices connected to the
+ telephone network.
+
+ Policies for the tpc.int subdomain are determined by its Board of
+ Arbitration and Conciliation. A Board of Arbitration and
+ Conciliation has its roots in English law, which permitted members of
+ a trade to appoint masters and workmen among them to serve as
+ councils of arbitration and conciliation for matters incapable of
+ being otherwise settled [10]. The Board of Arbitration and
+ Conciliation in the tpc.int subdomain consists of members of the
+ tpc.int subdomain cooperative appointed to hear and determine all
+ questions between members which may be submitted to them arising out
+ of the operation of services listed in the subdomain.
+
+ The initial Board of Arbitration and Conciliation is defined in this
+ document. Members of the Board shall serve for two-year terms except
+ that 50 percent or more of the initial Board shall serve for a one-
+ year term. The Board shall determine and publish procedures which
+ allow members of the tpc.int subdomain cooperative to select new
+ members of the Board as their terms expire.
+
+ If an issue relating to the definition of service or operation of
+ service listed within in the subdomain is raised and is incapable of
+ being settled otherwise, the matter shall be submitted by a member to
+ the Board of Arbitration and Conciliation. The Board shall hear the
+ question, making provisions for comments by other members of the
+ tpc.int subdomain cooperative and by the general public and shall
+ make and publish a determination of policy.
+
+ Secretariat services for the tpc.int subdomain are initially provided
+ by the Internet Multicasting Service, a non-profit corporation
+
+
+
+Malamud & Rose [Page 4]
+
+RFC 1530 General Principles and Policy October 1993
+
+
+ located in Washington, D.C. The tpc.int subdomain cooperative may
+ contract with other groups for the provision of secretariat services
+ at any time.
+
+ The tpc.int subdomain is organized as a cooperative to encourage
+ policy determination to be in the hands of those that are offering
+ the services. The subdomain encourages the establishment of a large
+ number of sites, combining the distributed local efforts of many
+ individuals and small groups into a global service.
+
+Provision of Services Listed in Other Subdomains
+
+ The primary purpose of the tpc.int subdomain is to provide
+ transparent mapping between the Internet and telephony environments.
+ Other logical subdomains may be established to provide similar
+ mappings. The Internet sites participating in those other subdomains
+ might also be registered under the tpc.int subdomain, or could choose
+ to be registered solely within those other subdomains with different
+ policies.
+
+ It is the policy of the tpc.int subdomain cooperative to encourage
+ the establishment of other service listing domains, either as a
+ public trust or cooperative or as a purely commercial venture.
