Internet-Draft ATIS PTSC Work Program October 2006
1. Introduction
At the 67th San Diego IETF Meeting it is anticipated that the Real-time
Applications and Infrastructure Area will meet and its ongoing work program will be an item for discussion. This Internet Draft has been prepared
to share the relevant portions of the PTSC current work program with
the IETF. It is hoped that awareness of the Packet Technologies
Systems Committee (PTSC) work program will allow for more informed
discussions to occur.
The PTSC defines its work program in the context of Issues. The PTSC
operates on the principle that one deliverable is typically produced
under one identified Issue (or project if you wish). It is important
to understand that the PTSC is quite prepared to recommend adoption
of existing standards should they be available and appropriate.
The PTSC wishes to maintain a good working relationship with the IETF
and sees the IETF as a rich potential source of IP related protocols.
2. PTSC Work Program
The PTSC is an ATIS sponsored technical committee. The PTSC develops
and recommends standards and Technical Reports related to packet
based services, architectures, and signaling, in addition to working
with related subjects under consideration in other North American and
international standards bodies. The PTSC is a major source of
proposed United States Positions to the ITU.
While the full PTSC work program is publicly available and can be
found at: http://www.atis.org/0191/issues.asp, this document will
identify those items that are related to this topical area and that
are active.
2.1. IP Interconnection, and Services & Capabilities
The following issue statements cover the topics related to general
network interconnection:
Issue S0010 - Authorizes development of an update to the interworking
requirements defined in T1.679 (SIP-I), as new RFCs become
approved and as ITU-T Recommendations are modified.
Issue S0014 - Authorizes development of a Technical Report assessing
which industry groups are developing operator services-related
standards for next generation equipment and what, if any, common
functions and architectures are emerging in support of operator
services in the IP space.
Issue S0018 - Authorizes development of a Technical Report that
defines an implementable architecture in support of IP QoS & RACs
for USA networks.
Issue S0019 - Authorizes development of a Technical Report that
defines an implementable architecture in support of IP QoS & RACs
for USA networks.
Issue S0021 - Authorizes development of a Technical Report describing
operator services functions and a common nomenclature and in
support of operator services in the IP space.
Issue S0023 - Authorizes development of Technical Report that
specifies a set of requirements for communicating IP traffic
priority and QoS parameters between applications and the IP
transport. Specific aspects of such a work program are the
following:
Call/Session Flow Identification
Vertical Interface Requirements
Issue S0024 - Authorizes development of a Technical Report that
defines the Session/Border Control Functions (S/BCF), performed
within various different network types. The functions required
depend on the interface. The document will include illustrative
examples of physical realizations of the functions. The physical
distribution of the functions will depend on scale, operational
and application needs.
Issue S0025 - Authorizes development of a Standard that defines the
NNI numbering and routing capabilities and procedures to promote
IP-IP interconnection between carriers in support of multi-media
services. This includes the support of carrier based ENUM.
Issue S0026 - Authorizes development of a Technical Report, in the
form of a users guide, on how to use SIP History-Info, between
networks and within a single network domain.
Issue S0027 - Authorizes development of a standard for a signaling/
control interface between an End User's SIP UA and an IP Service
Provider, with the focus on layer 4 and above, application
signaling and control. In addition to defining the interface in
support of the application services, the document will also
include procedures and call/signaling flows for device bootstrap,
discovery and data profile configuration.
Issue S0029 Authoriaes development of an Interworking Standard to Support ANSI Extensions to NSS.
Issue S0030 - Authorizes development of a Technical Report that
documents signaling to support Call Admission Control and Traffic
Management capabilities and procedures to be used between two IP
service providers, or within a service provider's domain.
Issue S0031 - Authorizes development of a Technical Report that
recommends application of packet priority markings and call
processing in managed IP networks.
Issue S0040 Authorizes extension of the NNI VoIP IP-IP interconnection standard, intended to facilitate interconnection between carriers, to address multimedia services in NGN
2.2. IP Emergency Telecommunication Services
Issue S0038 Authorizes development of a standard, applicable to managed IP networks using an NGN architecture, to support 911 Service.
Issue S0039 Authorizes development of a standard that recommends application of packet priority markings and call processing in managed IP networks based on future additions to DiffServ Code Points, such as a second Expedited Forwarding queue (with associated drop precedence, if applicable).
Issue S0041 Authorizes development of a standard that defines protocol and procedures for supporting ETS in NGN/IMS architectures, with a focus on security and authentication on IP access
Issue S0043 Authorizes development of a Technical report that captures the Technical Requirements that define the network element requirements for ETS Phase 1
Issue 45 Authorizes development of a Technical report that specifies the service requirements for ETS in an NGN environment
Issue 48 Authorizes development of ANSI IMS Standards
2.3. Security
2.3.1. Security at NNIs and UNIs
As telecom networks migrate the Network-to Network Interface (NNI)
from circuit switched to IP, there is a need for network control
security related specifications/ and standards which define the NNI
and the User Network Interface (UNI).
The PTSC is in the process of developing a suite of 5 Security IP
Dolly, et al. Expires March 24, 2007 [Page 5]
Internet-Draft ATIS PTSC Work Program October 2006
network interconnection related standards that deal with this
security area. These standards complement the security work already
undertaken by the ATIS TMOC Committee
(http://www.atis.org/0130/index.asp) and the security work currently
underway in the ATIS PRQC Committee
(http://www.atis.org/0010/index.asp).
The security related standards being produced by the PTSC are as
described in the issue statements below follows(note that issue
statements describe the deliverables of the PTSC):
Issue S0003 - Authorizes development of a standard which provides a
roadmap view of a subtending suite of standards, technical
reports, and requirements documents which provide a consistent set
of baseline security recommendations for the control and signaling
plane.
Issue S0006 - Authorizes development of a standard that describes
security issues specific to a VoP or Multimedia network
Issue S0007 - Authorizes development of a standard that addresses
security issues specific to the UNI access.
Issue S0046 Authorizes develop a standard that provides recommendations and specifies requirements for NGN Security based on the ATIS NGN Architecture.
2.3.2. Security Mechanisms for Messaging Applications
The following issue statement covers the Security Mechanisms for
Messaging Applications:
Issue S0032 - Authorizes development of a Technical Report that
details the minimum security mechanisms that carriers should
invoke, based on business objectives and policies for VoIP
messaging applications. The security mechanisms will address
aspects related to SPIT and application layer DoS attacks in both
signaling and data planes.
2.3.3. End to End User Authentication and Signaling Security
The following issue statement covers the End to End User
Authentication and Signaling Security:

>A mechanism(s) for a user to validate end-to-end security in
the presence of a "man in the middle network".
Issued S0051 Authorizes development of a standard that specifies a harmonized IdM approach for the ATIS NGN architecture
2.4. Lawfully Authorized Electronic Surveillance
The following issue statements cover the topics related to Lawfully
Authorized Electronic Surveillance (LAES):
Issue S0001 - Authorizes development of preparation of version 2 of
American National Standard T1.678 Lawfully Authorized Electronic
