Load balancing often involves destination network address translation so that the client of the load-balanced service is not fully aware of which server is handling its requests. Most network switches, however, are limited to supporting a single type of physical network, typically Ethernet, whereas a router may support different kinds of physical networks on different ports. Helpful to increase the bandwidth of the network. It uses lubricator, adhesive, plasticizer, solvent, and aluminum-oxide. The MLS was invented [1] by engineers at Digital Equipment Corporation . Bridges are good if a network is designed by the 80/20 rule: users spend 80 percent of their time on their local segment. Layer-7 switches may distribute the load based on uniform resource locators (URLs), or by using some installation-specific technique to recognize application-level transactions. Traditionally, routers use microprocessors to make forwarding decisions in software, while the switch performs only hardware-based packet switching (by specialized ASICs with the help of content-addressable memory). The interconnection of the layers also makes the circuit compact; thus, it reduces the weight. Layer-2 forwarding, usually referred to as switching, involves decisions based on frame or data-link headers. As a traditional switch, it can inspect frames. A home network with a switch must designate one computer as the gateway to the Internet, and that device must possess two network adapters for sharing, one for the home LAN and one for the Internet WAN.
