Intelligent application traffic management

The brain of the BIG-IP platform, Local Traffic Manager (LTM) intelligently manages network traffic so applications are always fast, available, and secure.

More than load balancing

BIG-IP Local Traffic Manager enables you to control network traffic, selecting the right destination based on server performance, security, and availability.

Full Proxy Means Full Power

Because BIG-IP LTM is a full proxy, you can inspect, manage, and report on application traffic entering and exiting your network. From basic load balancing to complex traffic management decisions based on client, server, or application status, BIG-IP LTM gives you granular control over app traffic.

Blazing-Fast SSL

The SSL performance of BIG-IP LTM lets you cost-effectively protect the end-to-end user experience by encrypting everything from the client to the server. It also scales on-demand and absorbs potentially crippling DDoS attacks. BIG-IP LTM includes levels of inspection necessary to block bad traffic and allow good traffic to pass through.

TCP Optimization

The highly optimized TCP/IP stack, TCP Express, combines TCP/IP techniques and improvements in the latest RFCs with extensions to minimize the effect of congestion and packet loss and recovery. Independent testing tools and customer experiences show TCP Express delivers up to a 2x performance gain for users and a 4x increase in bandwidth efficiency.    

Performance Optimization

BIG-IP LTM can optimize the speed and reliability of your applications via both network and application layers. Using real-time protocol and traffic management decisions based on application and server conditions, extensive connection management, and TCP and content offloading, BIG-IP LTM dramatically improves page load times. 


BIG-IP LTM is programmable, so you can take the visibility and control it provides and immediately act on it using iRules, F5’s event-driven scripting language. From defeating zero-day attacks to cloning specific app requests or dealing with custom application protocols, iRules let you adapt to application delivery challenges across any environment.

Scale and Speed

With BIG-IP LTM, you get a sophisticated, enterprise-class load balancer. You also get granular layer 7 control, SSL offloading and acceleration capabilities, and ScaleN technology that delivers on-demand scaling.

IoT Protocol Visibility

BIG-IP LTM enables support of IoT clients, publishing useful information to the MQ Telemetry Transport (MQTT) brokers (servers) through the MQTT protocol. Then, the MQTT brokers send the information to all subscribers. MQTT support means BIG-IP LTM can leverage MQTT traffic load balancing for your IoT clients.


From defeating zero-day attacks to dealing with custom application protocols, F5’s event-driven scripting language lets you adapt to application delivery challenges across the data center or the cloud.    

SSL Acceleration

SSL Acceleration

Offloads SSL encryption from data center servers and frees resources to boost app performance.    

Real-time Analytics

Real-time Analytics

See response time and traffic surges. Quickly get to the source of app performance issues.    

Full Elasticity

Full Elasticity

Provides clustering, virtualization, and on-demand scaling. 

Strong Security

Strong Security

Detects DDoS attacks and routes the connections away from critical servers.    



Maintain application availability by influencing traffic in real-time and understanding applications, protocols, and networks.

Deploy however you want


F5 application services work the same way in the public and private cloud as they do in the data center.    

Virtual Editions

BIG-IP VEs have the same features as those that run on F5 hardware—and you can deploy them on any hypervisor or select cloud provider.    


Both the F5 family of devices and the VIPRION chassis are purpose-built, powerful hardware that BIG-IP software runs on.


F5 application services integrate with major cloud providers and are available directly through marketplace offerings with variable PAYG or perpetual BYOL consumption options.
