Application Delivery Controller (ADC)

An application delivery controller (ADC) is a software application or hardware appliance that incorporates several tools, technologies and techniques for providing, controlling and monitoring access to web application servers.

Application Acceleration

Application acceleration is the optimization of web application traffic flow for increased backend server performance and faster content delivery to web application clients.

Active-Passive Redundancy

Active-Passive Redundancy is a high availability mode of operation whereby two or more identical instances of the same network device or appliance operate simultaneously but only instances marked as active serve client requests.

Active-Active Redundancy

Active-Active Redundancy is a high availability mode of operation whereby two or more instances of the same network device or appliance serve clients simultaneously and interchangeably.

Application Firewall

An application firewall inspects traffic destined for application servers to detect malicious or suspicious application requests. It can be configured to monitor, log and/or deny such requests.

Buffer Overflow

Buffer overflow is a state that occurs when a computer program writes more data into a temporary storage location (buffer) than the capacity of the location.

Anti-Phishing

Anti-phishing is a network security strategy for guarding against the unauthorized extraction of user identity information.

Advanced Compression

Advanced compression, in combination with other web application acceleration techniques, enables the further acceleration of content delivery to web and application clients over a network.

ActiveX

ActiveX is a Microsoft technology adapted from the older COM (Component Object Model) and OLE (Object Linking and Embedding) technologies for content delivery over the network (typically the World Wide Web).
