Telecoms & Internet converged Services & Protocols for Advanced Networking
Activity Report 2011

Chairman: Rainer Muench, Alcatel-Lucent

Responsible for all aspects of standardisation for present and future converged networks including Next Generation Networks (NGNs), fixed network interconnection and evolution, next generation network access, migration from switched circuit networks to packet based networks, interconnection scenarios, including but not limited to next generation corporate networks and next generation customer premises networks, the integration of multimedia services in the NGN (eg IPTV), and customer premises networks and devices (layer 2 and above)

In 2011, ETSI’s Telecommunication and Internet converged Services and Protocols for Advanced Networking Technical Committee (TC TISPAN) worked on three main aspects of standardisation: maintenance, enhancements and enabling future technologies.

NGN specifications are being maintained during the roll-out of NGN elements, to correct or clarify features. Testing is a major factor in the success of any technology, and new test specifications were developed to support NGNs in a number of key areas.

TC TISPAN is working on the infrastructure to support telephone number mapping (ENUM) and in August 2011 published a Technical Specification (TS) on ENUM and Domain Name System (DNS) principles for an inter-operator Internet Protocol (IP) backbone network. A TS on the requirements for types of numbers as identifiers in NGNs was also published in February. The Committee started work on a description of the usage of the DNS protocol in NGN. This will include a list of the different use cases for the DNS protocol in TISPAN architectures, the behaviour and details for DNS protocol usage, transport options for DNS messages, DNS protocol behaviour and configuration and options to increase the reliability of DNS protocol usage. By the end of 2011, an early draft of a new Technical Report (TR) had been completed.

Guidelines were elaborated addressing IP Multimedia Subsystem (IMS)-based NGN fixed network interconnection in relation to the IMS approach of the Third Generation Partnership Project (3GPP™).

The IMS-based IPTV interoperability test specification was updated and Release 3 was published in July 2011. It includes mapping for the interconnection of the IPTV TISPAN solutions with solutions defined by other standardisation organisations. This work was supported by an ETSI Specialist Task Force (STF 413).

Development of the services and architecture for a Content Delivery Network (CDN) for IPTV was completed in 2011. The Committee is now developing the protocol definition. In collaboration with ETSI’s Media Content Distribution Technical Committee (TC MCD), TC TISPAN initiated work on CDN interconnection architecture.

In support of European Commission Mandate M/493, TC TISPAN agreed to begin new work on a functional architecture to support European requirements on emergency caller location determination and transport. The objective is to define a single functional architecture to support European requirements on emergency caller location determination and transport needs to be developed in particular for the case where a Voice over IP (VoIP) service provider and one or several network operators – all serving the customer in the establishment of an emergency call – are independent enterprises needing to co operate to determine the location of the (nomadic) caller. The work addresses current pre IMS networks, is hosted by TC TISPAN and will be undertaken in collaboration with ETSI’s Access, Terminals, Transmission and Multiplexing (TC ATTM), Mobile Standards Group (TC MSG) and Broadband Radio Access Networks (TC BRAN) Technical Committees and the Emergency Telecommunications Special Committee (SC EMTEL). The target is to complete a new ETSI Standard in 2012.

In 2011, security work in TC TISPAN focused on IPTV, service and content protection, Customer Premises Networks (CPNs), the Network to Network Interface (NNI), prevention of unsolicited communications, threat analysis for customer networks and application layer security.

TC TISPAN defined the security services and mechanisms for CPNs connected to the TISPAN NGN. The Committee is working in close collaboration with ETSI’s Lawful Interception Technical Committee (TC LI) with the aim of publishing a specification on Data Retention for the NGN. This will include a mapping of the handover capabilities.

New work was started on a Threat and Vulnerability Risk Assessment (TVRA) of Smart Metering and relevant security requirements. Measures need to be in place to ensure public acceptance of Smart Metering data security and privacy safeguards, so that consumers can be confident that their data is secure. Due account will be taken of work elsewhere in ETSI and in other Standard Developing Organisations (SDOs).

During 2011, regulatory and public interest requirements relevant to NGN standardisation were analysed and correlated with existing specifications.

The Committee actively supported the ETSI Future Networks workshop and continued to discuss potential future work areas and their best organisation and management.

TC TISPAN concluded that future work would benefit from an improved technical organisation in ETSI and suggested to the ETSI Board that it should create a new technical body which would include the existing and future activities of TC TISPAN and a number of other Technical Committees as well as the Industry Specification Group on Autonomic Network Engineering for the Self-managing Future Internet (ISG AFI). This suggestion resulted in the establishment of the Board ad hoc group on Enhancing ETSI’s Network Activities (‘E2NA’) which considered proposals for creating a new Technical Body in 2012. TC TISPAN agreed to merge the entire Committee appropriately into the new structure, which would automatically mean the end of the TC TISPAN era.
