layer 7 routing

This is a creation in Article, where the information may have evolved or changed. absrtact: with the advent of Docker, PaaS, CaaS (Container as A Service), and even DCOs (DataCenter OS) present an explosive development. In PAAs, because instances generally default to dynamic IPs, for 7-layer calls (such as HTTP requests), 7-tier dynamic

Network Layer Routing and Application Layer Routing In the IP connection network, the correct communication between hosts is ensured by the correct routing. Here, the routing is not a hardware router, but a

So is there any way to implement the function of the three layer switch on the basis of still using the two layer device?The principle of layer one or three switches:Before we tell you how to solve the problem, we need to first understand how the three-layer switch works.

Inter-VLAN Routing 3 ways: One physical connection per VLAN, one-arm routing, three-layer switching.One physical connection per VLAN: A separate interface is assigned to each VLAN on the router, and a physical link is used to connect to the Layer two switch. When the host between the VLANs needs to communicate, the dat

broadcast to all ports. When the target machine responds to the source machine, the switch can learn which port the target MAC address corresponds, the next time you transmit data, you no longer need to broadcast all ports. The second-layer switch creates and maintains its own address table. Because L2 switches generally have a wide switching bus bandwidth, they can exchange data for many ports at the same time. If a L2 Switch has N ports, and the ba

increasingly popular requirements for Multi-Point multicast, such as distance vector Multicast Routing Protocol DVMRP ).The layer-3 Switch also supports self-learning. It can automatically discover the ing between the host's IP address and the connection port without using any routing protocol. Once a vswitch is connected to the network, it continuously learns t

At present, China's routing industry is developing rapidly, and it also promotes the update and upgrade of the Routing Switching Technology. Next we analyze the layer-2 to layer-7 Routing Switching technology. In the specific netw

development status is satisfactory. Therefore, the focus of selection is not at this level. However, as the core of the network, there is no substantial breakthrough in the router technology that acts as the interconnection between networks. Therefore, a new routing technology came into being-layer-3 switching technology, which is a routing technology because it

Over the past 20 years, network technology has continued to develop, from the initial X.25, frame relay, to Ethernet, FDDI, to the popular ATM, different technologies provide diverse network options. To achieve network interoperability among various types of LAN and WAN, you need to use the network protocol. The network protocol stack used by the Internet not only has low-level protocol specifications, such as TCP and IP protocols, in addition, high-level applications such as object email, analo

the packet, finding the route table for routing and forwarding, the three layer switch can realize mutual access between different VLANs by using the Direct connect route. The layer three switch configures the IP address for the interface. The use of SVI (Exchange Virtual Interface) to achieve inter-VLAN interconnection. SVI refers to creating a virtual interfac

between subnets, however, the layer-4 exchange technology alone cannot achieve mutual access between subnets. To solve this problem technically, network vendors developed a layer-3 Switch, also known as a router switch, using layer-3 exchange technology. It is a smart combination of traditional switches and routers.To put it simply, the
