cisco server load balancing

In many existing network applications, sometimes a server cannot meet the requirements of the client. In this case, you can only add servers to solve the problem. Is there a way or technology to solve this problem? Use the network load balancing cluster in Windows 2000 or Windows Server 2003 (This article describes how

on the same server, which is a deep hidden danger of equalization. 2.3. FairThe fair policy is an extended policy that is not compiled into the Nginx kernel by default. The principle is to determine the load according to the response time of the back-end server, from which the lightest-load machine is selected for div

One of Linux load Balancing software LVS (concept article) A brief introduction of LVSLVS is the short name of Linux virtual server, the Linux VM, a free software project initiated by Dr. Zhangwensong, and its official site is www.linuxvirtualserver.org. Now that LVS is already part of the Linux standard kernel, Before the Linux2.4 kernel, the use of LVS must be

network dataAbility to handle, improve network flexibility and usability. Load balancing has two meanings: first, a large number of concurrent access or data traffic sharing to multiple node devices to deal with, reduce the user waiting for response time;Point device to do parallel processing, after each node device processing, the results are summarized, returned to the user, system processing capacity ha

Nginx is a server software that is also a high-performance HTTP and reverse proxy server, as well as a proxy mail server. In other words, we can publish the website on the Nginx, can realize the load balance (enhances the reply efficiency, avoids the server crashes), but als

Linux load balancing based on two-NIC binding technology for PlatformMaintaining high availability of servers is an important factor in an enterprise-wide IT environment. One of the most important is the high availability of server network connections. Network interface card (NIC) binding technology helps ensure high availability features and provides additional

HSRPcisco and VRRP are the most common gateway redundancy technologies. Similar to VRRP, HSRP is composed of multiple routers. A vro is a virtual gateway, and a vro is active. It is replaced by a device to implement transparent switching to users. However, we hope to achieve redundancy at the same time. Load Balancing to make full use of the capabilities of the device, GLBP (
