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

    • Complete the basic configuration

    • Virtual-server

    • Load Balanced Pool

    • Node nodes

    • Profile

    • Monitor

    • IRule

    • Rate adjustment

    • SSL Certificate

    • SNAT

    • Statistical data
