One of the main factors that hindering people from adopting and use Internet of things (IoT) based products and services is its complexity. [179] Installation and setup is a challenge to people, therefore, there is a need for IoT devices to mix match and configure themselves automatically to provide different services at different situation.

Each host can belong to several groups of redundancy. Each host must have a second unique IP address. A common use of CARP is the creation of a group of redundant firewalls. The virtual IP address allotted to the group of redundancy is indicated as the address of the default router on the computers behind this group of firewalls. If the main ...
An Internet of things (IoT) gateway provides the bridge (protocol converter) between IoT devices in the field, the cloud, and user equipment such as smartphones. The IoT gateway provides a communication link between the field and the cloud, and may provide offline services and real-time control of devices in the field. [15] [16]
REST is a scalable architecture which allows for things to communicate over Hypertext Transfer Protocol and is easily adopted for IoT applications to provide communication from a thing to a central web server. [35] MQTT is a publish-subscribe architecture on top of TCP/IP which allows for bi-directional communication between a thing and a MQTT ...
Each Gateway provides the connection to the Internet backbone for the gateway beam(s) it serves. The system of gateways comprising the satellite ground system provides all network services for satellite and corresponding terrestrial connectivity. Each gateway provides a multiservice access network for subscriber terminal connections to the ...
In general, edge devices are normally routers that provide authenticated access (most commonly PPPoA and PPPoE) to faster, more efficient backbone and core networks.The trend is to make the edge device smart and the core device(s) "dumb and fast", so edge routers often include quality of service (QoS) and multi-service functions to manage different types of traffic.
A residential gateway is a small consumer-grade gateway which bridges network access between connected local area network (LAN) hosts to a wide area network (WAN) (such as the Internet) via a modem, or directly connects to a WAN (as in EttH), while routing. The WAN is a larger computer network, generally operated by an Internet service provider.
As a result of virtualization, private cloud, converged, and hyper-converged infrastructure adoption, east-west traffic volumes have increased. Today many virtual functions including virtual firewalls, load balancers and other software-defined networking (SDN) perform various functions and services that previously ran on physical hardware.
