Principally this refers to an ability to use source and destination port numbers in TCP and UDP communications to allow, block and prioritize communications.[4]. When troubleshooting one problem, it is very easy to "correct" a configuration error that causes a much bigger problem. By the way, the OSI model is a reference model for describing network communications. Routing domains are also called autonomous systems. 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. Multilayer switching is a relatively new technology that combines a router and a switch into one device, giving an administrator the best of both worlds . Work in harsh environmental conditions. Language |. Huawei Enterprise Support Community. There are circuits on both sides of a double-sided PCB, but for the circuits to work, there must be a proper circuit connection between the two sides of the circuit board. Multilayer PCBs have a very high component density. Modern load balancing routers can use different rules to make decisions on where to route traffic. The first advantage of multilayer PCBs is their compact size. The hardware inside a Layer 3 switch blends that of typical switches and routers, replacing some of a router's software . Determine the number of VLANs that will be used, and the IP address range (subnet) youre going to use for each VLAN. Because the courses only appear on one side, this circuit board is called Single-sided PCB. Legacy inter-VLAN routing using a physical router port for each VLAN, router-on-a-stick inter-VLAN routing, and multilayer switch inter-VLAN routing. Then, the multilayer switch configuration is finished. There are various layers, and the interconnection between them requires extra precision. The latest machinery is required to create multilayer PCBs; these cannot be created using the standard PCB machinery used for a single-layer PCB. If the network grows at a fast pace, it will eventually outgrow the two core switches, and will be forced to add two additional switches, which means you will have to add more to your routers. The benefit and use depend entirely on what you intend to do. Verdict 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. 2. Electronic PCB Assembly Process and Flow Chart. Faster connectivity - With multilayer switches, you gain the benefits of both switching and routing on the same platform.
