Gartner delivers technology research to global technology business leaders to make informed decisions on key initiatives.
A software modification inserted into an operating system or application, to intercept the normal data flow and provide additional functionality. Often used by third-party vendors to provide enhanced networking features.

Shared services or shared services center (SSC) refers to a dedicated unit (including people, processes and technologies) that is structured as a centralized point of service and is focused on defined business functions. These functions are supported by IT and IT services for multiple business units within the enterprise. Shared services may come from several different physical locations, and may involve numerous business functions and IT processes. The definition, structure and scope of an SSC start within the enterprise. Enterprises sometimes engage external providers to consult with various elements of the design, structure, location options and execution options. Execution and long-term delivery may be by internal enterprise personnel or by service providers, or some combination thereof. Consequently, the definition of shared services is independent from the sourcing option for delivery.
Industry:Technology
A system-level facility to enable shadowing or mirroring (i.e., duplication) of selected databases to a separate disk or disk set. The purpose is to minimize the space required for backup data while providing for the continuation of critical processing in the event of the loss of a disk containing related databases.

A framework of seven types of activity that do not add value; originally defined by Toyota: overproducing — producing product before there’s a valid order; unnecessary waiting — lengthened cycle time, which reduces agility; unnecessary transportation — unnecessary transportation of material between sites; overprocessing — processes longer or more complex than necessary; unnecessary inventory — buildup of work-in-process or raw materials; unnecessary movement — inefficient workplace; layout causing extra work; and too many defects — poor process quality and too much rework. This list was extended by Gartner and others to include an eighth waste: asset underutilization or other underutilization of resources. The eight wastes are often referred to by the acronym “DOWNTIME,” meaning “Defects, Overproduction, Waiting, Nonutilized resources, Transportation, Inventory, Motion and Excessive processing.”

Session Initiation Protocol (SIP) is a communication protocol specified by the Internet Engineering Task Force (IETF). It’s the first real-time communication protocol to enable multiuser sessions, regardless of media content. SIP enables a new generation of communication services across the Internet, as well as over fixed and mobile IP networks. SIP enables communications to be initiated and managed, and its key channels include voice, video and instant messaging (IM).

SBCs connect IP networks (enterprise to service provider) and introduce new edge requirements in three major areas: security, service assurance and law enforcement. SBCs sit at the edge of the service provider’s network and complement established routers with their ability to perform required control functions by integrating session signaling and media control. SBCs operate as SIP back-to-back user agents, MGCP proxy/network-address translations (NATs) and/or H.323 back-to-back gateways. They are both the source and the destination of all signaling messages and media streams entering and leaving the provider’s network.
The SBC space has been largely cornered by startup vendors, but other equipment vendors have taken two approaches: they have partnered with the SBC vendors or embedded SBC functionality into some of their existing solutions, such as routers. Gartner recognizes that there are some embedded solutions with SBC function, but counts only those that are stand-alone. Vendors such as Cisco and Sonus Networks have integrated SBCs into their routing and switching platforms.
Industry:Technology
A form of server-based Java that operates in conjunction with a Web server and offers an alternative to using Common Gateway Interface (CGI) and server application programming interfaces (SAPIs) to communicate with Web server processes. In addition, servlets are independent of a given type of Web server, as the most prominent Web servers support servlets.
Industry:Technology
Part of the GPRS infrastructure, the SGSN provides switching functionality, security and authentication via the HLR for GPRS users. The SGSN’s primary interfaces are with the GGSN, HLR and PCU.
