Switched networks provide exclusive connectivity to sites
The LAN switching network provides an exclusive point-to-point link for each user station, enabling a traditional network that can only serve a single user to be converted into a highly parallel system at a time, and simultaneously supports multiple chains between multiple pairs of communication devices. road. The current switching network is mainly used for interconnection and exchange of network segments. When the network segment is minimized, there is only one user node to realize point-to-point exchange.
High bandwidth and flexible interface speed
Since the exchange provides an exclusive connection to the site, the connected device can get a full 10Mbps Ethemet or 16Mbps Token Ring bandwidth. The user site can be connected to the switching device through an exclusive 10Mbps Ethernet connection and can also be connected to the server via a 100Mbps high-speed Ethernet link. The exchange network has such an interface speed independent feature, which effectively solves the network bottleneck and response time problem.
Logical network is easy to manage
The real implementation of high-speed switching networks makes virtual networks a reality. The so-called "virtual" is the use of software to combine some end users who belong to different network segments into a work group, just like working on a network segment that is "actually connected", regardless of whether they are really In the same building or in the same building group.
A virtual network is also a logical network. On the virtual network, users and the corresponding network resources can perform various logical combinations required. For example, any port on any Smart HUB can be assigned to any network segment without any actual wiring work. Any configuration or resource changes on the network can be made on the administrator's workstation without having to change any workstation addresses, routers, servers, and wiring. This greatly reduces the burden of network management and greatly reduces the time required to respond to network users moving.
At the heart of the switching network are switching switches (such as switches, switching routers, and ATM switches) or network control centers that replace the bus and terminal controllers of the original network to form a star topology that can connect multiple pairs of endpoints.
