F5-BIG-IP-LTM Study Notes (i)

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
