As optical broadband access networks have been popularized, triple play services using IP technologies, such as Internet access, IP telephony, and IP video distributing services, have been also popularized. However, consumers expect new services for a more comfortable life. Especially, when QoS guarantee and high reliable services are provided in NGN (Next Generation Network) era, various home network services over NGN are deployed. For this purpose, the home gateway has been installed in consumer houses for the connection between access and home networks, and providing various services to consumers. Even though, the broadband router currently plays a role similar to the home gateway, this home gateway should comprehend functionalities of the broadband router, and should have additional features. The functional requirements of such home gateway have been discussed in standard bodies. That is, the next generation home gateway in NGN era generally should have four features as follows; High performance for IP processing, Compliance with the interface of carrier grade infrastructure including NGN, Flexible platform for various services, and Easy management and maintenance. This chapter describes the standardization of the home gateway and, proposes its evolution scenario the present to the future. Then, it also proposes these four requirements, and technologies to comply with features described above.

Popularities Of Internet And Broadband Services

This section describes the present and the future broadband services which motivate an installation of home networks and the home gateway.

The growth of Internet has been continued worldwide. Figure 1 shows report of ITU-D (See, ITU-D (2008)) about the popularity of Internet worldwide. The number of Internet users currently occupies only 17% of worldwide residents. However, its growing rate is rapid. In particular, broadband services by DSL (Digital Subscriber Line), FTTH (Fiber To The Home), and cable modem has been installed. As shown in Figures 2 and 3 (See, ITU-D (2008)), the number of users of broadband services has been increased. Especially, in US, Asia, and European countries, the number of users is grown up rapidly. As broadband services provides high speed IP based communication by economic and fixed rate for consumers, consumers enjoy IP centric triple play services, such as high speed Internet access, IP telephony, IP video distribution services.
