Network Gateway Router

"A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. ...
Readily identifiable icons are used to depict common network appliances e.g. Router, and the style of lines between them indicate the type of connection. Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without indicating the specifics of the outside network. ...
At different scales diagrams may represent various levels of network granularity. At the LAN level, individual nodes may represent individual physical devices, such as hubs or file servers, while at the WAN level, individual nodes may represent entire cities. In addition, when the scope of a diagram crosses the common LAN/ MAN/ WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes."

"Mobile/ cloud computing is the combination of cloud computing and mobile networks to bring benefits for mobile users, network operators, as well as cloud computing providers. The ultimate goal of MCC (mean of MCC is Mobile/ Cloud Computing) is to enable execution of rich mobile applications on a plethora of mobile devices, with a rich user experience. MCC provides business opportunities for mobile network operators as well as cloud providers." [Mobile cloud computing. Wikipedia]

Cicso Intelligent Service Gateway (ISG), a technology from Cisco Systems, to manage subscribers in Broadband, Wireline & Wireless deployments.
"The Cisco Intelligent Services Gateway offers Service Providers an opportunity to take direct control of resources and characteristics in their broadband network to deliver next generation services by:
(1) Controlling, securing & differentiating services via intelligent policies embedded directly in the network or received via open and standards-based control interfaces to the BSS.
(2) Customizing Service Convergence with zero-touch provisioning across customized networks.
(3) Distributing IP Session control into the network while simultaneously maintaining consistent PPP session control." [cisco.com/ en/ US/ products/ ps6588/ products_ ios_ protocol_ group_ home.html]

"A cable television headend is a master facility for receiving television signals for processing and distribution over a CATV system. The headend facility is normally unstaffed and surrounded by some type of security fencing and is typically a building or large shed housing electronic equipment used to receive and re-transmit video over the local cable infrastructure. One can also find head ends in power line communication (PLC) substations and Internet communications networks." [Cable television headend. Wikipedia]
