Last time an e-commerce client needs to be built as a framework.192.168.1.100/URL1 (request URL)-->node1:10.0.0.4, 10.0.0.5 (server IP)192.168.1.100/URL2 (request URL)-->node2:10.0.0.6, 10.0.0.7 (server IP)A client allocates traffic based on the request URL,/URL1 traffic goes to Node1, and then Node1 the node for a traffic load. Then this scenario can use seven-layer load balancing (application Gateway) + f
Router and three-layer switch experiment Demo--a gateway that acts as a two VLAN--Hundred dishes background : We know that routers have routing capabilities, so you know how to configure two gateways on a router interface (such as a two VLAN gateway)? Note that it is on one interface instead of two, and we sometimes use the three-

technology, high-performance network processor, and rich Application Intelligence, this greatly improves the availability, security, and scalability of key business applications. ServerIron 450 and 850 provide comprehensive application traffic and content exchange functions, including Server Load balancer, URL-based and Cookie-based switching, global Server Load balancer, and transparent high-speed cache switching.
At the same time, Foundry launched a high-performance and intelligent ServerIron
The OSI Layer-7 model enables reliable communication between different networks of different systems through seven hierarchical structural models. Therefore, its most basic function is to help different types of hosts transmit data.

. If a long piece of data is passed over, the above is 1, then the communication is a high potential, and it looks like a straight line. What the receiver sees is a line drawn up by the high potential, and there is no way to know how many bits are transferred.
Therefore, each potential also has a bit time attribute, that is, the width of the potential in the graph. When transmitting data, the sender not only needs to express 0, 1 with a high/low potential, but also needs to hide the clock sent b
