backbone network from conventional third layer to comprehensive third-layer, fourth-layer switching function, its unique WAN integration capability and the access control based on layer fourth exchange have played a key role in secure and orderly network data transmission. In addition, Cabletron SmartSwitch router provides different levels of prioritization for specific business application data exchange based on the QoS features of layer fourth swit

, not the difference between the nodes, if the balance on the WAN, the response time for the user to choose the nearest server is of practical significance , and the more dispersed the cluster topology, the more effective the method can be. This approach is the primary approach to advanced balancing based on topology redirection.3. 6 Weighting methodWeighted methods can only be used in combination with othe

(This article applies to TL-ER6120 V1.0, TL-ER5120 V1.0, TL-ER5520G V1.0, TL-R483 V3.0, TL-R478 + V5.0, TL-WVR300 V1.0)Some application environments, such as enterprises or schools, have their own internal network and need to access the Internet. Multiple WAN port routers are selected to connect both the internal network and the Internet. If no corresponding settings are made, the data accessing the internal network may be sent to the Internet. Simila

server can be a Web server, a mail server, an FTP server , a DNS server, one or more of the video servers, and each real server is connected through a high-speed LAN or across a WAN. In a real-world application, Director server can also be the role of real server concurrently. As can be seen from the entire LVS structure, director server is the core of the entire LVS, currently, the operating system for director server can only be Linux and FreeBSD,

Understanding Server Load balancer firstTransferAndForwardingDifferences: The transfer and forwarding process is similar to whether customers and outsourcing companies need to directly contact each other. If the contact is received by the receiver. Transparency between customers and outsourcing companies means forwarding.Transfer: to transfer data packets from the client to the actual server, you need to know the address of the actual server.Forward:

as early as possible before it enters the process user address space from the kernel buffer. And because the scheduler can be used under the application layer, these load-balancing systems can support more network service protocols, such as Ftp,smtp,dns, as well as applications such as streaming media and VoIP.DNAT: Reverse NAT, place the actual server in the internal network, and the NAT server as the gat

server Load balancer Technology for network applications. It is completely isolated from switches and servers and becomes an independent technical device. This is the object we will discuss now. Generally, Server Load balancer is divided into seven layers based on different network layers. The second layer of Server Load balancer refers to the use of multiple ph

LVS introduction: The LVS cluster has three configuration modes: DR, Tun, and Nat. You can perform Load Balancing for WWW Service, FTP service, and mail service. below, you can build a load balancing instance for WWW Service, DRDs-based LVS cluster configuration Director-server: core server of LVS, which is similar t

The LVS (Linuxvirtualserver) Cluster type is usually described by LVSDirector's request to relay to the cluster node. Currently, there are three available methods: the number of nodes that can be owned when the network address translation (LVS-NAT) different network 10 ~ 20 direct routing (LVS-DR) (Scheduler) same network high (100) ip tunneling (LVS-TUN) Support WAN high (100) Basic LoadBalancer structure: Level 3 The LVS (Linux virtual server) Clust

iptables, Linux kernel operations, performance compared with the reverse proxy server does not have a qualitative leap; IP load balancing still needs to forward requests to the actual server, at the same time, the response from the actual server needs to be forwarded to the user. Therefore, the performance bottleneck of the server comes from the performance and network bandwidth of the NAT server;3: Direct

server, port ing is required on both public lines to serve the Internet user groups on different lines. Iii. Solution 1. Add a link load balancing device in the solution, connect the network cables connected to the WAN port and WAN1 port of the VPN device to the link Load Balancin
