随着经济的发展和计算机网络技术的不断更新,越来越多的企事业单位准备组建自己的局域网,已提高其经济效益和办公效率,交换机作为重要的网络设备,其选购至关重要。因此在选购交换机时,我们应做到以下几个方面:1、了解转发方式数据包的转发方式主要分为“直通式转发”(现为准直通式转发)和“存储式转发”。由于不同的方式适应于不同的网络环境,因此,我们应当根据需要做出相应的选择。由于“直通式转发”指检查数据包的包头,不需要存储,所以切入方式具有延迟小,交换速度快的优点。存储转发方式在数据处理时延时大,但它可以对进入交换机的数据包进行错误检测,并且能支持不同速率的输入/输出
With the economic development and continuous updating of computer network technology, more and more enterprises and institutions are ready to set up their own LANs, which have increased their economic efficiency and office efficiency. As an important network equipment, switches are of vital importance. Therefore, in the purchase of switches, we should do the following: 1, to understand the forwarding mode Packet forwarding is mainly divided into “straight-forward forwarding” (now aligned forwarding) and “storage forwarding ”. As different ways to adapt to different network environments, so we should make the appropriate choice according to need. Because “straightforward forwarding ” refers to check the header of the data packet, do not need to store, so the cut-in mode has the advantages of small delay, fast switching speed. Storage and forwarding methods in the data processing delay, but it can enter the switch packet error detection, and can support different rates of input / output
