Analysis on the development of broadband access in Japan and America NGN has become a hot topic in the communications industry. It has become a consensus that the current network will gradually transition to NGN. Japan ’s NTT has taken the lead in launching the NGN commercial network. Large US telecommunications companies are also actively exploring the development path of NGN. The main purpose of developing NGN is to IPize fixed telephones to meet development needs. In addition, NGN can bring great convenience to users, which is mainly manifested in the following aspects: through FMC, people can easily use the phone no matter where they are; NGN realizes the integration of the three networks, and can provide people with telephones and TVs through one network. And high-speed Internet access; in the broadband business, it can also provide telemedicine, remote teaching, video conferencing and logistics management based on RFID; the two-layer structure of separation of application and control is particularly suitable for business applications and network development, so it is generally welcomed .

Since NGN is a new thing, the transition to NGN will not be a model. Japan and the United States are very hot in building NGN and triple play, especially in business integration, but the difference is also obvious.
Japan's broadband access is progressing rapidly
Japan has launched cablemodem since October 1996, xDSL in 1999, and broadband access technologies such as FTTH in March 2001. Due to fierce market competition, the government has formulated some policy directions, so Japanese users' optical fiber has developed rapidly. According to statistics, by the end of December 2005, there were 4.637 million FTTH users in Japan, of which NTT's FTTH users were 2.82 million. According to the data released by the Ministry of Internal Affairs and Communications of Japan, by the end of the second quarter of 2006, the number of optical fiber users in Japan reached 6.31 million, and its share in the broadband user market has accounted for 23.4%, second only to ADSL. The broadband access technology of the two largest users has made Japan one of the world's largest optical fiber users in one fell swoop.
By the end of the first quarter of 2007, FTTH users in Japan had grown to 8.8 million, with a market share of 33%, ADSL users were 14.1 million, and the market share dropped to 53%. At this time, the total number of broadband users reached 26.43 million; As of the end of June 2007, the number of Japanese fiber broadband users reached 9.663 million, accounting for 36% of the total broadband users, while the number of ADSL users was 13.786 million, and the proportion of ADSL users in the total number of broadband users also fell from the original 53% To 51%. For the six consecutive quarters from the first quarter of 2005 to the second quarter of 2006, the number of users of FTTH increased more than that of ADSL. At the same time, by the second quarter of 2006, ADSL experienced negative growth.
The total number of broadband users in Japan increased by 1.6% from December 31, 2007 to March 31, 2008. By the end of March 2008, the number of broadband access users reached 28,749,700, including NTT ’s East The West Japan Company increased by 1%, and its market share reached 46.8%; the second place was SoftBank, whose broadband access users decreased by 0.8%, and its market share was 17%. FTTH increased by 7.3% during the same period, and the total number of users reached 12.153 million, of which NTT East and West Japan ’s market share increased by 0.8% to 72.2%, ranking first; power companies have not changed and the market share remains unchanged. 10.2%; KDDI decreased by 0.3% and the market share was 5.8%; USEN also decreased by 0.3% and the market share was 4.6%. From the perspective of the types of optical fiber users, NTT East and West Japan ’s market share in detached residential buildings and commercial users increased by 0.4% to 78.4%; DSL share decreased by 3.2% over the same period and the total reached 12.711 million Households.
According to data released by the Ministry of Internal Affairs and Communications of Japan on June 17, 2008, NTT East and West Japan's FTTH market share has reached 72.2%, and their IP phone market share has exceeded 30%.
A notable feature of the Japanese broadband access market in recent years is that FTTH is growing rapidly, while DSL continues to decline, and cable modem market share is not high. By the end of June 2008, FTTH and DSL had reversed, and the total number of FTTH users has exceeded that of DSL. User number.
In August 2006, the Japanese government published an article "Broadband Development Strategy to 2010", which proposed that ultra-high-speed broadband such as user fiber should be available to Japanese households. By the end of March 2007, Japan ’s ultra-high-speed broadband had covered 95% of Japanese households, and the Japanese government planned to cover all Japanese households by 2010.
U.S. broadband access has grown strongly in recent years
Due to the large size of the United States, the network setup in many suburbs and rural areas is not perfect. In addition, the scattered population makes the network setup cost relatively expensive. According to the survey, by 2007, 18% of households in the United States still use dial-up Internet access.
Facing the strong demand of the broadband access user market in recent years, telecommunications companies have not missed the opportunity to launch user fiber services with higher transmission rates, such as the user fiber system FiOS (formerly FTTP) launched by Verizon, which currently provides users with three different Rate service, that is, the transmission rate is 5Mbit / s, 2Mbit / s, 15Mbit / s, 2Mbit / s, 30Mbit / s, 5Mbit / sk, and the monthly fee is $ 34.95 , US $ 44.95 and US $ 179.95, and plans to cover 16 million households by 2010, so that 50% of the users of this network can enjoy optical fiber services. at & t also announced that it intends to strengthen the construction of users' optical fiber networks in the next three years, provide users with high-speed Internet access, IPTV and telephone bundling services, and transfer 50% of the users of this network to be carried by the user's optical fiber network.
According to a survey by PaksAssociates, 33 million households will have 10Mbit / s access capacity in the United States by 2012, compared with 5.7 million households in 2007, accounting for 9% of broadband users. In 2007, the broadband penetration rate of American households exceeded 50 %. By the end of 2007, there were more than 60 million U.S. households connected to the Internet via broadband, accounting for about 55% of U.S. households. US communications operator Qwest launched a DSL program with a higher rate in late April 2008, which was launched in 23 major markets in the United States. The specific charges are as follows: the download rate is 20Mbit / s, and the monthly charge is $ 104.99; the download rate is 12Mbit / s, and the monthly charge is $ 51.99. If bundled with local calls, the price of both services is reduced by $ 5. In order to provide a higher broadband access rate, Qwest said it will invest US $ 300 million to upgrade the existing network and introduce fiber to nearby areas.
