Management traffic in emerging remote configuration mechanisms for residential gateways and home devices

XML technology is penetrating the network management in the IETF, UPnP, and DSL forum suite of standards and protocols. The advantages of XML are offered at the cost of long byte streams due to XML's inherently verbose nature. The increase in packet size for remote configuration and management can pose problems, if executed in a point-to-multipoint arrangement comprising one automatic configuration server and thousands of home gateways and multimedia devices. We investigate and exploit the repetitive nature of text patterns in typical XML documents as produced by the configuration and management tasks and as coded in SOAP RPCs. The solution mainly comes from application of the Lempel-Ziv compression algorithm, with minimal additions in the proposed DSL Forum standard. Numerical and experimental results support the applicability and advantages of the proposed approach and provide insight on how these are attributable to different layers of the employed protocol stack.

홈 네트워크 환경에서 홈 게이트웨이와 관리 서버 개발

본 논문에서는 두 개의 시스템을 제안한다. 하나는 홈 네트워크 환경에서 각종 디지털 정보가전들을 효율적으로 연결/제어할 수 있는 홈 게이트웨이이다. 다른 하나는 흠 게이트웨이의 물리적인 한계를 극복하기 위한 관리 서버이다. 홈 게이트웨이는 이더넷/ADSL과 같은 TCP/IP 네트워킹 기능을 지원하며, HomePNA, IEEE1394, PLC와 같은 홈 네트워크 기능, PSTN/SLT, VoIP, 비디오 통신과 같은 통신기능을 구현하였으며, 향후 디지털 홈 환경에서의 핵심 네트워크 장비가 될 것이다. 관리 서버는 한 지역 내에 설치된 흠 게이트웨이와 이와 연동된 각 가정 내의 다양한 디지털 정보가전 및 HA(Home Automation) 기기들을 통합 관리/제어하는 특정 서버이다. This paper proposes two systems. One is a Home Gateway(HG) which efficiently connects and controls digital appliances in the home network environments. The other is a Management Server(MS) that overcomes the physical limitation of the HG. The HG supports networking modules(TCP/IP for Ethernet, ADSL), home networking functions(HomePNA, IEEE1394 PLC) and telecommunication system(PSTN/SLT, VoIP, Video Communication). The HG is expected to be a core device for the integrated digital home environments. The MS is a dedicated server which manages and controls individual HG, home appliances and HA devices implemented at an area.

UPnP AV Architectural Multimedia System with a Home Gateway Powered by the OSGi Platform

The key issue of multimedia systems in home network environment is interoperability among different kinds of multimedia devices. And, as for multimedia content providers outside a home, another issue of multimedia systems in home network environment is how to provide the multimedia service from the outside of a home. We developed a UPnP AV architectural multimedia system with a home gateway powered by the OSGi platform, which gives interoperability among multimedia home devices in home network environment, and a powerful tool for multimedia content providers to provide smarter multimedia service for users in a home.

Super-Pipelined Implementation of IP Packet Classification

Abstract With developing all-optical communication networks, highly-functional and highspeed boundary routers and home gateways are becoming to be required. In this paper, high-speed pipelined algorithm for packet classification which is one of heavy load functions within boundary routers is proposed. Its software implementation scheme on a data-driven processor equipped with flexible capability of pipelined parallel processing is also discussed. Finally, it is shown at maximum performance exchanged for simulation and experimental hardware evaluation that the scheme achieves 12M IPv4 packets per second by only 6% additional hardware cost.

Automatic control of household activity using speech recognition and natural language

Speech recognition and natural language parsing components are used to extract the meaning of the user's spoken input. The system stores a semantic representation of an electronic activity guide, and the contents of the guide can be mapped into the grammars used by the natural language parser. Thus, when the user wishes to navigate through the complex menu structure of the electronic activity guide, he or she only needs to speak in natural language sentences. The system automatically filters the contents of the guide and supplies the user with on-screen display or synthesized speech responses to the user's request. The system allows the user to communicate in a natural way with a variety of devices communicating with the home network or home gateway.

Home network infrastructure for handheld/wearable appliances

A server infrastructure allows wireless wearable appliances or portable handsets to access consumer services offered via the server. Services are accessed via a universal home services interface (UHSI) which is shared by all access devices. The UHSI can include a voice-activated interface to simplify usage from non-graphical terminals. In a home network, the infrastructure resides on a home gateway or central home computer and allows users access to local subsystems or external WAN services. An implementation based on a universal plug and play (UPnP) home network is described.

Broadband in the Home

Despite the fact that well over half the population is now served by ADSL-equipped exchanges (at March 2002 there were 1010 exchanges enabled for broadband), the take-up of broadband, particularly in the home, is very low. By March 2002 there were 145 000 customers signed up for broadband; a year ago there were only 40 000. Clearly price is a key factor in the decision-making process and recent announcements from the BT Group lowering the wholesale price of asymmetric digital subscriber line (ADSL) should enable the market to grow more quickly and compete with product offerings from other providers such as cable. However, it is not just about price. To really feel the expenditure is worthwhile, the user must believe that they are getting genuine benefits from the service as they exploit the potential of the additional bandwidth. To do this effectively, some form of home distribution is required. Due to the potential diversity of the services that could be offered, some type of home gateway that is straightforward to install and use is also a necessity. Various solutions exist today which could help fulfil this role, e.g. the PC, a set-top box, a router, etc, but in reality it is likely that all these functions need to be combined in a low-cost, consumer-oriented package. This paper examines the practical problems of installing broadband in the home, the need for a self-install option, the development of a practical home network and the need for a home gateway.

Broad bandwidth through DSL

Based on the work of TTG‐4, which defined and identified the various configurations, characteristics and patterns of deployment of broad bandwidth through DSL technology. Looks at tactical matters, implications of higher bandwidth services, home gateway products, and wireless as an increasing threat to profitable deployment of DSL.

Home gateway architecture and its implementation

We propose a home network architecture, which integrates heterogeneous home network environments. Our architecture incorporates various home network technologies into the gateway technology. We use link-layer dependent protocols within a single network communication, and, in contrast, we use the gateway technology when the communication is over multiple networks. We also propose home gateway architectures, which are the key component of the residential network. The home gateway interconnects the home networks and the public (access) network. We show the requirements of the home gateway and its software design. We implemented the experimental home gateway system, which is based on the Web server enhanced with Java facilities. The home gateway interconnects the Internet on the public network side, and the home networks (IEEE 1394 AV network and the home automation power line network). It also has a real-time MPEG4 transcoding function which transcodes AV data on IEEE1394 into MPEG4 video that is suitable for transmitting through the Internet. The home gateway provides the capability of remote control of the connected appliances on the home networks from the Internet, and the AV data transmission/translation capabilities.

Mapping home-network appliances to TCP/IP sockets using a three-tiered home gateway architecture

A three-tier gateway architecture for internetworking between home automation networks and a TCP/IP based wide area network, such as the Internet, is described. The architecture abstracts the functionality of any home network into a driver layer (tier one), and provides a common access layer (tier two) from any TCP/IP network application (tier three) to a local home automation network. Clients and application programs may transparently access services and resources on the home network and appliances connected to the home network may access resources and services on the TCP/IP network.
