最近,实达网络在S1824F 10/100M自适应交换机基础上推出了S1826G 10/100/1000M交换机。据厂家提供的信息,这是国内厂商首次推出的针对分支中心的千兆交换机。它为用户千兆主干网提供最大具有两个千兆口的分支线速交换设备,解决了分支中心百兆交换机在信息流量大时可能出现的瓶颈问题,以低成本方式实现了分支中心的千兆交换。尽管国内大部分局域(城域)网的主干早已实现了千兆交换,但是由接入层到主干网的分支中心多数依然采用百兆交换机。分支中心难以采用千兆交换的原因是由于目前市场上的千兆交换机价格昂贵。随着用户端设备速度的不断提高、用户数量以及业务规模和种类的迅速扩大,网络流量 Recently, Shida Networks introduced the S1826G 10/100 / 1000M switch based on the S1824F 10 / 100M Adaptive Switch. According to the information provided by the manufacturers, this is the first time for domestic manufacturers to introduce a gigabit switch for the branch center. It provides users with a maximum of two trillion trunks of Gigabit line backbone branch line speed switching equipment to solve the branch center hundred megabytes switch in the flow of information may be a bottleneck problem that low cost way to achieve the branch center Mega exchange. Although the backbone of most local (metropolitan) networks in China has already realized the gigabit exchange, most of the branch centers from the access layer to the backbone still use Fast Switch. The reason why branch centers are hard to adopt gigabit switching is that the gigabit switches on the market are currently expensive. With the increasing speed of the client device, the number of users and the rapid expansion of business scale and types of network traffic
