A multi-service gateway (MSG) is a highly integrated device that combines multiple network functions and data communications into one single service, a very budgetary solution targeted at small and medium enterprises (SMEs) and retail setting. The functions of a multi-service gateway include routing, VoIP, and security instructions like VPN, firewall and IPS/IDS. More advanced smart gateways may also be programmed with web filtering, email server, high-volume storage and wireless networking hub.
Application Delivery Controllers are networking devices that reside in the data center and serve as a key part of an application delivery network. With the explosion in Internet traffic, business applications, and the number of Internet-enabled devices, application delivery controllers provide the front-end intelligence that supplements and enhances enterprise application flows like traffic offloading, load balancing and DMZ buffering.
In order to provide access to data on any device at locations such as stadiums, shopping centers and medium-sized branch offices as well as campuses, content providers and telecom companies are required to build their information superhighways on both wired and wireless networks that deliver enterprise-scale capacity, stringent performance and reliability.
WAN optimization, also known as WAN acceleration, is a set of technologies and/or techniques applied to maximize the efficiency of data flow across a wide area network (WAN). In an enterprise WAN, the goal of optimization is to increase the data transfer speed and bandwidth regarding accesses to critical applications and information.
Unified Threat Management, frequently abbreviated as UTM, is a single appliance that specializes in all-inclusive security functions, such as network firewall, intrusion detection/prevention system (IDS/IPS), anti-virus gateway, anti-spam gateway, VPN, content filtering, load balancing, data loss prevention and appliance monitoring.
