multi wan load balancing

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

rapid expansion of deployment scale, front-end load balancing is also beginning to become rich.Soft loadAfter entering the Internet company, when we first started to develop the application, the business scale small user quantity is not big, the machine quantity also is few (In front of a LVS followed by several application services, and later in order to facilitate the division by the domain name and suit

configure it? That is, the network segment division.Another important reason why Server Load balancer does not use the protocol stack modification method is that the route directs network layer datagram while the network layer is end-to-end,It is not a broadcast network, which is essentially different from the link layer.We know that Ethernet is a broadcast network. Although the address learning mechanism of a vswitch isolates the broadcast domain, i

Load Balancing with HaproxyFirst, the conceptHaproxy is a free and open source software written in the C language [1] that provides high availability, load balancing, and application proxies based on TCP and HTTP.Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven

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

Software load Balancing is generally implemented in two ways: the implementation of soft load based on operating system and the implementation of soft load based on third party application. LVS is a kind of soft load based on Linux operating system, Haproxy is an open source

LVS Load Balancing clusterTypes of clusters1, load Balancing cluster: To improve the corresponding ability of the application system, as far as possible to deal with more corresponding requests, less latency as the target, get the overall performance of high load concurrency

When the system administrator finds that the network performance is poor, the system administrator can allocate resources through network load balancing to optimize the resources. The development of the Internet has brought infinite fun to people's lives and brought infinite convenience to people's work. However, the rapid development of the network also makes people highly dependent on the network. Today,

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

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
