Broadband in-premises networking
(Continuation of Question 18/15 & 19/15 (ex Q9/9 in 2013-2016))
Motivation
The continuing customer demand for ever higher bit rate data services, high-speed Internet access and other innovative services, and the ongoing needs of network operators to leverage in-premises connectivity for distributing within the home IPTV and other applications, will require the development of new Recommendations and enhancements to existing Recommendations covering all requirements and implementation aspects of in-premises Networking Transceivers. These studies will include, but are not limited to, the transport of higher layer protocols, the management and testing of in-premises systems, security aspects, spectral management aspects and energy saving techniques.
The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: J.190 through J.192, G.9951 through G.9954, G.9960 through G.9964, G.9972, G.9973, G.9977 and G.9979.
The target audience for this question are the technology suppliers, chipset vendors, equipment vendors, cable operators and service providers active in the domain of providing broadband in-premises networking. A global audience is targeted to facilitate a unified approach to the broadband in-premises networking.
Question
What performance characteristics should broadband in-premises networks possess in order to satisfactorily transport data streams associated with specific services as these streams are passed between access network and the in-premises network and across the in-premises network to the terminal device?
What enhancements are needed to the G.9951 through G.9954, G.9960 through G.9964, G.9972, G.9973, G.9977 and G.9979 Recommendations:
- in the light of design, network deployment experience, and evolving service requirements?
- to optimise the transport of IP-based services?
What new Recommendations or revisions to existing Recommendations are needed:
- for broadband transceivers for in-premises networking over various mediums such as phone-line, coaxial, data (e.g. CAT5), power cables and plastic optical fibre?
- for broadband transceivers for in-premises networking using visible light communication (VLC)?
- to carry out line testing?
- to enable higher bit rates to be achieved by means of MIMO?
- to enable transport of higher layer protocols?
- to optimize the quality-of-experience to the end user?
- to provide secure admission to an in-premises network?
- to facilitate coexistence between various technologies sharing the same spectrum?
- to facilitate inter-domain communication between different mediums to optimize the choice of delivery path for data and ensure end-to-end QoS and QoE?
- to support timing synchronization mechanisms necessary for audio/video delivery?
What enhancements:
- to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries?
- to developing or new Recommendations are required to provide such energy savings?
What mechanisms for:
- network management should be employed to provision new network-based advanced services to devices connected to the broadband in-premises networks?
- application management should be employed to provision advanced applications to devices connected to the broadband in-premises networks?
- security should be employed to provide protection of the broadband in-premises networks?
- seamless interconnection should be employed between multiple devices for advanced services in broadband in-premises networks?
- mechanisms should be employed to support efficient, less cumbersome and low maintenance on broadband in-premises networks?
Study items include, but are not limited to:
- Requirements for advanced service capabilities over broadband in-premises networks.
- Modulation and transport techniques, tools for spectrum management (including dynamic spectrum management), real noise environments, handshaking procedures, testing procedures, physical layer management procedures, protocols for PLC coexistence, energy saving techniques.
- These studies should take account of the different regulatory environments around the world.
- Transceiver to higher layer inter-connection techniques.Modulation and transport techniques, tools for spectrum management (including dynamic spectrum management), real noise environments, handshaking procedures, testing procedures, physical layer management procedures, protocols for PLC coexistence, energy saving techniques.
These studies will include any specific requirements:
- To optimise the transport of IP-based services.
- To optimise the transport of Ethernet based services.
- To support the management of in-premises networking systems operating over various mediums.
