unequal cost load balancing

, F5, etc., these products are expensive, but value for money, can provide very good performance and very flexible management capabilities. Yahoo China at the beginning of nearly 2000 servers using three or four alteon to be done.Web design software four-layer exchangeWhen you know the principle of hardware layer four switch, the software four layer exchange based on the OSI model comes into being, so the solution achieves the same principle, but the performance is slightly worse. But to meet a

DNS load balancing is the first implementation of load balancing technology. Configuring the same name for multiple addresses in a DNS configuration file is configured with multiple A records pointing to a different IP, and the client will randomly obtain one of the addresses when querying this a record. It is not diff

increase the website operation cost, in addition, a single Server also has performance and thread bottlenecks. When the concurrency traffic is large and concentrated on one Server, "Server too busy" appears, in this case, what method should the webmaster use to make the website still have better access results when there is a high traffic volume? This involves the question of Server Load balancer. We have

"Blog recommendation" Some misconceptions about the use of load balancing technologyToday, load balancing is not a fresh word, nor is it a new technology, mainly used to solve the limitations of single-machine load capacity , but the problem is that your application really t

dynamically register and discover services so that the service location is transparent. The service provider address list is obtained from the consumer to achieve soft load balancing and Failover, reducing the dependency on F5 hardware Load balancer and reducing part of the cost. (2) As the dependency between services

of virtualization, cloud computing and "on demand" it. F5 is headquartered in Seattle, WA and has branches around the world.Product Technical Features:1) Load balancing support more comprehensiveBig-IP LTM (local traffic management) includes static and dynamic load balancing methods, including dynamic rate, least-conn

With the widespread popularization of Internet application, the storage and access of massive data has become the bottleneck problem of system design. For a large-scale Internet application, every day millions even hundreds of millions of PV undoubtedly caused a considerable load on the database. The stability and scalability of the system caused great problems. First, load

In the Internet Distributed system, many services are data storage-related, mass access, direct access to storage media is not resistant, need to use Cache,cache cluster load balancing algorithm becomes an important topic, here to the existing load balancing algorithm to some summary.BTW: Although the cache

Ieee802.1s is used to resolve excessive spanning tree problems. There are two meanings of configuring pvst+: 1. Using pvst+ to achieve Network Load Balancing 2. Configure the speed port "Enable speed port will save 30S of forwarding time delay"1. Let's do an experiment to verify. First of all, we still build the topology diagram in the virtual machine GNS3, and mark all the parameters that are needed. Such

Because these days I took almost all my time on studying Microsoft Windows 2000 Server and Advanced Server. maybe this has nothing to do with programming or software architecture or OO methodology, but I think when you develop an enterprise application you shocould consider the network load balancing, the server performance, CPU performance, memory performance and the disk performance. In this topic, I

Objective:What is DNS polling?A domain name for multiple IP A records resolution, the DNS server will resolve the request in the order of a records, one by one assigned to a different IP, so that the simple load balancing the benefits of DNS polling: 0 Cost: Just binding a few a records on the DNS server, domain registrars are generally Provides free parsing serv

to the user, the time of the traffic pattern can greatly improve the scalability of the cluster system, this method does not have the cost of IP tunneling,There is no need for the real server in the cluster to support the IP tunneling protocol, except that the scheduler and the real server have a NIC attached to the same physical network segment. Among the three IP load

LVS (Linux Virtual Server) is a software system for load balancing, consisting of the Ipvs framework that actually works in the kernel section and the ipvsadm used to write rules in user space. The way to work is to distribute access requests to the back-end production servers through the set of scheduling methods and rules. Dr. Zhangwensong is the founder and main developer of LVS.Load

ADSL, such as broadband access because of its economic and adequate, that is, cost-effective advantages of many small and medium-sized enterprises favored. With the development of enterprise business, especially for some medium-sized enterprises and enterprises with high dependence on network, they will consider bandwidth expansion or planning large bandwidth access. Multi-line broadband access is often its first choice, there will be some enterprises
