Simple and efficient building solutions for gigabit smart Switches

With the development of the exchange industry in China, the wide application of gigabit smart switches has been greatly promoted. At present, Gigabit smart switches have improved many shortcomings and provide users with a good user experience. Tcls4rjsfb of TCL Network Equipment Co., Ltd. is a gigabit smart switch with Simple Network Management and belongs to working group-level network equipment. Based on the mature chip solution, it is specially designed to optimize the features of Community users such as abrupt and high traffic access and diversified natural environment conditions, so as to achieve small size, good sealing performance, and a wide operating temperature and humidity range, it provides simple and efficient building solutions for the Community FTTB Ethernet access.

In addition to the 8-port 10/100 MRJ-45 interface, tcls4rjsfb has a base-fx optical fiber interface, it provides reliable conversion between electrical signals and optical signals based on the electrical circuit connection function of an ordinary Gigabit smart switch product, users only need one 10/100 M Ethernet card to enjoy the efficiency and convenience brought by the high-speed bandwidth from M to the desktop.

As a public network connected to the Internet, the Community network is mainly in a star data communication mode, that is, users do not need to directly communicate with each other. In order to protect the security of users, they cannot directly communicate with each other. Generally, hardware vendors can set VLAN for a gigabit smart switch to partition data streams at the data link layer, the second layer of OSI/ISO. S4w.sfb supports a maximum of seven VLAN virtual subnets), which can meet the security requirements of a single floor of a common apartment. It also uses port-based VLAN division to minimize the difficulty of network maintenance.

S4127sfb uses a 2 MB port buffer space to coordinate the speed matching problem between different network devices, and stores burst data in the buffer zone for processing by slow devices, in order to avoid sudden high-traffic network congestion for Community users during a specific period of time, such as PM. At the same time, s4w.sfb adopts advanced and mature buffer scheduling algorithms to reduce the addressing time of gigabit smart switches in normal communication, effectively control the costs of devices, and avoid packet loss errors.

Based on reliable product quality, carriers can build a seamless 10/100 Mbps Ethernet Switching Network System Using s4da-sfb to provide unified network services for the entire network system. Such a network system is simple and reliable, it also integrates scalable network speed and performance. S4w.sfb has been widely used in Intelligent Community construction. Currently, thousands of s4w.sfb instances are widely used in Yangzhou radio and television community construction and Zhenjiang Radio and Television construction projects as Gigabit smart switches for building access.

The Phase I project of Zhenjiang Radio and Television uses three Gigabit smart switches to form a ring-shaped POS ring. Second-level switches are mainly used for aggregation, and Gigabit Optical Fiber uplink backbone switches are used, the aggregation layer and user access layer use a large number of gigabit smart switches TCLS4226MF and Simple Network Management Switch tcls4rjsfb in the "high-speed Trunk Line" series of TCL network equipment companies.
