f5 load balancing algorithms

Load BalancerIt can be a dedicated device or an application that runs on a common server. Distribute requests to servers that have the same content or provide the same services. Special purpose devices are generally only Ethernet interfaces, which can be said to be a multi-layer switch. The load balancer is typically assigned a virtual IP address, and all requests from the client are done for the virtual IP

Load Balancing problems in multi-core programmingAuthor: Zhou weiming related article links: Lock competition in multi-core programming several difficulties of multi-core programming and their countermeasures (problem 1) OpenMP parallel programming (2) OpenMP parallel programming (1) fast sorting efficiency on dual-core CPU the lock competition problem in multi-core programming mentioned in this article is

balancer is limited by network I/O and bandwidth is limited under certain hardware conditions. However, by improving algorithms and improving the hardware performance of the Server Load balancer program, to increase the bandwidth limit. We can also see that different service types occupy different server resources. The load measurement strategy we use is to eval

cactiAdvantages of LVS:Good performance, close to hardware equipment network throughput and connection load capacity.LVS's Dr mode, which supports load balancing over a WAN. None of this other load balancing software is currently available.Disadvantages:More heavy. Another

translation can effectively solve the CPU and disk I/O load on the server, however, the performance of the Server Load balancer is limited by network I/O and bandwidth is limited under certain hardware conditions. However, by improving algorithms and improving the hardware performance of the Server Load balancer progr

protocols, such as the Outlook Web App. So on the load balancer this layer, no longer special need for the load office weighing products to support client affinity.Let me say a few more words, from the level of the mailbox connection to the level of the Web connection request. As mentioned earlier, older versions of Exchange have problems requiring clients to re-authenticate without client affinity support

computational power, even on a single-core CPU that runs fast and does not have much impact on load balancing, the actual load balancing takes into account large computational and large-scale software that requires load balancing

technology, and Cisco's Etherchannel technology are all studying the link aggregation technology that binds multiple Nic interfaces of the server, the link aggregation technology virtualizes multiple links into one logical link, which provides a cheap and effective way to expand the bandwidth of network devices and servers and improve network flexibility and availability. This article introduces the bonding Technology in Linux. This technology is used in Linux 2.4.x kernel. With bonding technol

Citrix NetScaler Load Balancing algorithmhttp://blog.51cto.com/caojin/1926308As we all know, Citrix NetScaler, which delivers products as a new generation of applications, has the industry's leading data control, application delivery capabilities, but as one of the fundamental content of ADC capabilities, it is not possible to adapt to so many scenarios without a robust, diversified equalization algorithm I

Recent Friends Liu Xin website successfully online and operation, PV reached billion/day access, the most front-end use of haproxy+keepalived dual-machine load balancer/reverse agent, the entire site is very stable; it made me more determined haproxy+ Keepalived as the web's most front-end load equalizer Web site architecture design, here I also have a point to tell you: Many friends worry about the softwar

What is load balancing Load balancing, the English name is load Balance, refers to the multiple servers in a symmetric way to form a collection of servers, each server has an equivalent status, can be provided separately from external services without the assistance of othe

, parsing time is long, during the parsing process, the user access to the site will fail; Low scalability: DNS Load Balancing control in the domain name vendor, it can not do more to improve and expand; Poor maintainability: Also does not reflect the current running state of the server, the number of supported algorithms, can not distinguish between serv
