How to build a more optimized Broadband Access Network

Broadband access networks are currently the most commonly used access technology. However, we still have many problems that need to be solved and considered in order to better serve users. Designers must also design reasonable and optimized implementation solutions, meet various user needs. In the boom in broadband network construction in China, Shida network has established close cooperation with major telecom operators such as China Telecom, China Netcom, China tietong, and China Unicom, as well as broadband resident network operators, provides a series of broadband network products for the construction of Broadband IP networks in China, with perfect solutions, excellent product quality, and excellent services, the service has been highly recognized by China Netcom, China Telecom, changkuan, Shandong bailing, and other operators,

The "operable, manageable, and profitable" broadband access network solution provided by alicloud has made achievements in telecom operators in improving network intelligence, simplifying network management, ensuring network security, and reducing network operation costs. extraordinary. In the construction of the broadband resident Network of China Netcom Shanghai Branch, Shida network provides a series of broadband network products and complete solutions, all aspects of network management, network operation, authentication and billing, and network security are considered.

Project Background
Currently, China Netcom Shanghai Branch has adopted a variety of broadband access network solutions and technologies in the Construction of broadband access networks. Its business model is basically subscription billing. With the continuous development of the resident broadband access network, the Business Development Direction of China Netcom Shanghai Branch is growing, such as CNC Connected, broadband access to student residences in colleges and universities, and broadband access to high-end hotels. China Netcom Shanghai Branch gradually felt that the traditional broadband access network method could not provide subdivided, close-fitting, and perfect access services, so it put forward new demands for the construction of the resident network. As the shortlisted manufacturer of China Netcom's broadband network equipment selection, Shida network provides a complete broadband IP address resident network solution based on the broadband network construction requirements of China Netcom's Shanghai Branch, this solution provides a broadband IP address resident network that is "operational, manageable, and profitable.

Solution Design
Netcom broadband community construction adopts the FTTx + ETTH networking mode, residential center adopts the real-up STAR-S2800 modular switch. The vswitch features network management, high port density, high backboard bandwidth, modular design, and flexible port organization. STAR-S2800 has 8 module slots, and there are 7 kinds of modules for the user to choose from, the STAR-M2840 routing module can make the STAR-S2800 switch has three layer routing switching function. Flexible STAR-S2800 port form, support 10 Mbit/s/100 Mbit/s/Mbit/s twisted pair cable, Mbit/s single multi-mode optical fiber and gigabit LX/SX optical fiber, board bandwidth up to 22 Gbit/s, fully supports wire speed forwarding within 1 Gbit/s. The STAR-S2800 switch provides the basis for upgrading and resizing of the residential center based on its modular design. It provides a powerful guarantee for the performance of the residential network with its high backboard bandwidth and support for Routing Switching.

On the corridor side of the residential area, China Netcom adopted a real-up STAR-S1924F +, S2024M stacked switch, provides rich remote management functions, supports port isolation, port security control, port aggregation, port monitoring, multicast, etc, security Control functions such as static port address lock, dynamic address lock, and mac address filtering provide reliable guarantee for managing the community network and restricting the logon of illegal users.

Features
The broadband Community solution of Shida network in China Netcom Shanghai Branch has the following features.
1. Convenient management. Vswitches of Shida network management support multiple management modes, including out-of-band serial port, in-band Web, TELNET, and S-Manager network management software. S-Manager Network Management Software Enterprise Edition) provides comprehensive performance, fault, security, alarm, and configuration management.
2. easy maintenance. The self-developed S-Manager Network Management Platform supports SNMP V1.0/2.0, snmp mib-II, Ethernet-like MIB, Bridge MIB, and Start Enterprise MIB, and RMON Statistics, History, Alarm, and Event group management can realize remote fault alarms and Automatic logging of devices.
3. support expansion. The center of the residential area uses modular devices. Therefore, you only need to add new modules for future resizing.
4. Supports multimedia applications.
◆ Network phone number. All vswitches support the 802.1P priority protocol. It provides four-level Queues with priority, providing the basis for running voice calls on the broadband network in the future.
◆ Vod. All switches support the IGMP protocol. It provides the IGMP Snooping function, enabling the community network to support large-scale nVOD services.
5. diverse billing methods. Real-time switches and a series of network products support multiple authentication and billing modes, including 802.1X, PPPoE, Web, and Portal/. Different billing modes can be adopted as needed. Each billing mode allows users to accurately time and calculate traffic on the Internet. Supports multiple settlement policies of carriers and provides multiple service modes.

In general, as a professional network communication equipment supplier, the real-time network keeps pace with the times. According to the needs of the broadband resident network construction of China Netcom Shanghai Branch, provides a complete residential broadband access network solution for billing methods and network management.
