建设将是今后小区建设的一个努力方向。
　　１小区用户的三种主要宽带接入解决方案
　　目前，在我国小区宽带网接入技术主要有三种：
　　１．１ＦＴＴＸ＋ＬＡＮ接入方式
　　ＦＴＴＸ是ＦＴＴＨ（光纤到户）、ＦＴＴＢ（光纤到大楼）、ＦＴＴＣ（光纤到路边）的统称。ＦＴＴＸ＋ＬＡＮ接入方式是指用户端的ＩＰ以太网（计算机＋网卡）接入中国电信或其它电信的光纤ＩＰ骨干网。宽带网络按其技术结构来说可以分为宽带骨干网、宽带汇聚网和宽带接入网三个部分。骨干网是所有信息元素传输的基础通道，信息单元和数据就是通过骨干

网络实现从源地址到目的地址的转移。宽带汇聚网络通过对信息的接收、分拣和转发的过程，实现了信息的相互交换过程。接入网是整个宽带网络中与用户相连的最后一段，用户通过接入网连接到宽带网上，如图１所示。
　　本方式具备以下特点和优势：
　　１．１．１高骨干网带宽，高用户接入速率
　　宽带网骨干带宽高达１００Ｇ，出口带宽高达２．５Ｇ。宽带网采用快速以太网技术，小区接入速率高达１Ｇ（１０００Ｍ）家庭用户以１０Ｍ／１００Ｍ速度全交换方式接入。
　　１．１．２网络安全
　　具有ＩＰ地址禁止盗用、用户数据严格分离的功能，用户不必担
Building will be a future direction for residential construction.
1 plot the user's three main broadband access solutions
At present, China's residential broadband access technologies, there are three:
1.1 FTTX + LAN access methods
FTTX is FTTH (fiber to the home), FTTB (Fiber to the Building), FTTC (fiber to the curb) collectively. FTTX + LAN access method refers to the client's IP Ethernet (computer + network card) to access China Telecom's fiber optic telecommunications or other IP backbone network. Broadband network for its technological structure can be divided into broadband backbone network, broadband convergence networks and broadband access network in three parts. Backbone network is the basis of all information elements in transmission channel, information units and data is through the backbone

Network destination address from source address to the transfer. Broadband convergence network information by receiving, sorting and forwarding process, realize information exchange process. The broadband access network is connected to the network in the last paragraph of the user, users connected to broadband Internet access network, shown in Figure 1.
This approach has the following characteristics and advantages:
1.1.1 high-bandwidth backbone network, high speed user access
Broadband network backbone bandwidth of up to 100G, the export bandwidth of up to 2.5G. Broadband network using Fast Ethernet technology, community access rates up to 1G (1000M)  home users to exchange all manner 10M/100M speed access.
1.1.2 Network Security
With the IP address against theft, the strict separation of user data, users need not worry
