f5 load balancing algorithms

2008 Sina Podcast is composed of static server cluster and dynamic server cluster, static server cluster uses squid to do front-end cache, dynamic server is also called interface server, mainly used to achieve display playback, record playback logs and so on. The interface server uses F5 big-IP hardware four/Seven load balancer switch, 4 nginx reverse proxy Server four layer

Recently, I spoke with instructor Gao about the load balancing solution for nginx and tomcat clusters. Interesting. I thought about the WCF technology used in my project, so I thought about how to implement load balancing in WCF. After a while, Google found that the routing service of wcf4.0 seemed to be able to be imp

distribution algorithmOf course you might want to use different algorithms for load balancing, for example, according to the number of requests, or according to the flow balance, the instructions used here are LbmethodPossible values for Lbmethod are:Lbmethod=byrequests by Request number equalization (default)Lbmethod=bytraffic according to the flow balanceLbmet

Using Web Sphere Edge Server to build Load Balancing for cold rolling Systems A user's ERP system has been running for eight years. The Cold Rolling Workshop system has been running for nearly five years. Its core business system is the cold rolling Data Summary Query System, which is built based on the WAS, DB2, and Power minicomputer environment, stable Operation till now. Since the cold rolling query fun

shown in:When 18.49 of this server's IIS stops, we look again at the server state inside the server farms as shown in:When 18.49 was hung up, we visited the 50.32 server again, and the results came out:Conclusion: When more than one IIS server is configured, according to our defined equalization rules and algorithms, it will automatically coordinate and allocate the current request to achieve the purpose of the diversion, in the above demo, when 18.4

Python implements mysql read/write splitting and load balancing, and pythonmysql Oracle Database has a supporting rac developed by its company to achieve load balancing. Currently, the maximum number of known nodes can reach 128, but the maintenance cost is undoubtedly very high, in addition, rac stability is not parti

. The tried records whether the server is currently trying to connect. He is a bitmap. If the number of servers is less than 32, you can record all server states in one int. If the number of servers is greater than 32, you need to request memory in the memory pool for storage. The use of this bitmap array can be referenced in the following code:Finally, the actual strategy code, logic is very simple, code implementation is only 30 lines, directly on the code.2.2. IP HashThe IP hash is another

From http://www.cnblogs.com/allen0118/p/4294066.htmlIn the large-scale Web application system, due to the large amount of data requested and the factors of concurrency, the web system will be the phenomenon of downtime, the method of solving this kind of problem I personally think mainly in the following areas:1.IIS load Balancing.2. Database load

Software load balancing is generally implemented in two ways: software load implementation based on the operating system and software load implementation based on third-party applications. LVS is a kind of soft load based on the Linux operating system. HAProxy is an open-sou

Before we took two articles, we explained in detail the nginx principle, installation and feature components. See Load Balancing Layer Design (2)--nginx installation (http://blog.csdn.net/yinwenjie/article/details/46620711) and architecture design: Load Balancing layer Design (3)-- Nginx Advanced "(http://blog.csdn.net
