f5 loadbalancer

Load balancer and supports third-party server Load balancer, or even hardware Server Load balancer. The following describes how to configure AAS built-in Server Load balancer and third-party server Load balancer. One native advantage of Using AAS's built-in Load balancer is that AAS's built-in distributed session management can ensure the high performance of the cluster and the high availability of sessions. After the server in the cluster fails, session switching is very timely, so the

that can be connected within the cluster. Nodeport and LoadBalancer are two types that open services to external networks. The legal value of the ServiceType field is: L Clusterip: Use only one IP address within the cluster-this is the default. Choosing this value means that you only want the service to be accessible within the cluster. L Nodeport: on the basis of the internal IP of the cluster, the service is opened on the port of each node of the c

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

F5 session persistence, f5 session In recent projects, F5 needs to be used for load balancing and relevant information should be recorded. The following is a description of the relevant parameters in the F5 change application. Let's take a look at them. Let's pick several important parameters to learn.

Enter in the URL address bar: Such a refresh, you can see in the Firebug, only a few requests will be sent out, and almost no picture of the request, this is because the request will first check whether the local cache of the requested picture, If there is a cache and there is no expiration (the expiration can be viewed through the header of the picture request), he will not issue the picture requests.F5:f5 refresh is slightly slower than enter, for w

, the system returns 304 not modified. After the browser receives the modification, it reads the content from the cache. If it is modified, the system returns 200.OK, and new content is returned. In this situation, you find a box of expired milk, and ask someone else if they can drink it. If someone else says yes, you will drink it. If someone else says no, then you haveFind a box of fresh milk. For F5 refresh, the HTTP request message header is as

Pressing CTRL + F5 in Internet Explorer is a convenient way to force the page to be reloaded. All components of the page (images, CSS, JavaScript, and so on) are forcibly reloaded. it is equivalent to using an empty cache IE to access a page. F5 is a simple refresh of the current page, click Ctrl + R, or right-click to refresh, it is the same, they have"If-modified"String. If you view

Based on the huge network structure, the use of Cluster Server brings a lot of load problems such as traffic. So the relative, load-balanced technology also emerged. Each technology requires product support, so let's now look at one of the F5 load balancers. So first of all, we first introduce the structure of the product function.Many vendors have launched a load balancer dedicated to balancing server load, such as NetScaler of
