I. Overview of F5-BIG-IP functions
1, the role of the big-IP local traffic management function (ltp:local traffic Management) is to intercept and reboot the incoming network traffic, so as to intelligently adjust the load of the server.
2. Overview of local traffic management functions
Scalability is achieved by adjusting and distributing the load on the network server.
Offload Standard server tasks such as HTTP data compression, SSL authentication, and SSL encryption to improve server performance.
Monitor server status and performance
Establish, manage sessions, and continuity of connections
Perform authentication and authorization functions for application traffic based on user name/password and SSL certificate authentication information.
Manage packet throughput to optimize performance for specific connection types.
Increase performance by aggregating multiple client requests to the server-side pool.
Apply configuration settings to customize traffic for specific apps (such as HTTP and SSL traffic)
Customize the management of specific connections using scripts written in tool command Language (TCL).
3. Manage specific types of application traffic
Write irules, assign specific connections to each application,
Inserts the header data into a specific app's request, and then directs the request based on that header data.
Implement session persistence. Using the LTM, you can configure session persistence based on data such as HTTP cookies, source IP addresses, destination IP addresses, and SSL session IDs.
Monitor server status or performance in the pool.
use a dynamic rate load balancing algorithm to evaluate and load specific server types .
4. Optimize performance
5. Uninstalling Server Tasks
6. Optimize TCP and HTTP connections
7, OneConnect
Content conversion, when an HTTP client sends multiple requests in a single connection, the LTM is able to process each of these requests separately, sending them to different destination servers on demand, which automatically starts without configuration.
Connect the pool, combining unused server-side combinations so that other clients can use them.
Oneconnect conversion, for http/1.0 requests, sometimes you may want to add keep-alive support in the Http-connection header to ensure long connections, which is called oneconnect conversion.
8. HTTP pipelining Technology
9. Rate adjustment
10. TCP Optimization
11. Enhance network security
12. Configuration Overview
