Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by the American National Standards Institute and ITU-T for digital transmission of multiple types of traffic. ATM was developed to meet the needs of the Broadband Integrated Services Digital Network as defined in the late 1980s, and designed to integrate telecommunication networks. It can handle both traditional high-throughput data traffic and real-time, low-latency content such as telephony (voice) and video. ATM provides functionality that uses features of circuit switching and packet switching networks by using asynchronous time-division multiplexing.
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other network interfaces.
A network switch is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
A web hosting service is a type of Internet hosting service that hosts websites for clients, i.e. it offers the facilities required for them to create and maintain a site and makes it accessible on the World Wide Web. Companies providing web hosting services are sometimes called web hosts.
Power-line communication, abbreviated as PLC, carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers.
Uptime is a measure of system reliability, expressed as the percentage of time a machine, typically a computer, has been working and available. Uptime is the opposite of downtime.
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects. Other terms that may be used for RTU are remote telemetry unit and remote telecontrol unit.
The next-generation network (NGN) is a body of key architectural changes in telecommunication core and access networks. The general idea behind the NGN is that one network transports all information and services by encapsulating these into IP packets, similar to those used on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term all IP is also sometimes used to describe the transformation of formerly telephone-centric networks toward NGN.
In engineering and systems theory, redundancy is the intentional duplication of critical components or functions of a system with the goal of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
Catalyst is the brand for a variety of network switches, wireless controllers, and wireless access points sold by Cisco Systems. While commonly associated with Ethernet switches, a number of different types of network interfaces have been available throughout the history of the brand. Cisco acquired several different companies and rebranded their products as different versions of the Catalyst product line. The original Catalyst 5000 and 6000 series were based on technology acquired from Crescendo Communications. The 1700, 1900, and 2800 series Catalysts came from Grand Junction Networks, and the Catalyst 3000 series came from Kalpana in 1994.
High availability (HA) is a characteristic of a system that aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.
Machine to machine (M2M) is direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the information it records to application software that can use it. Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer.
Perle Systems is a technology company that develops and manufactures serial to Ethernet, fiber to Ethernet, I/O connectivity, and device networking equipment. These types of products are commonly used to establish network connectivity across multiple locations, securely transmit sensitive information across a LAN, and remotely monitor and control networked devices via out-of-band management.
The term downtime is used to refer to periods when a system is unavailable.
Opengear is a global computer network technology company headquartered in Edison, New Jersey, U.S., with R&D operations in Brisbane, Qld, Australia and production in Sandy, UT.
Juniper E-Series is a series of broadband services routers or edge routers manufactured by Juniper Networks. The E series was originally developed by Unisphere Networks, which Juniper acquired in 2002. These routers provide multiple services including broadband remote access server, broadband video services, dedicated access, 802.11 wireless subscriber management, VOIP, internet access, security services, network address translation (NAT) etc. on a single platform. The carrier-class architecture of E-series routers allows to combine Broadband Remote Access Server (B-RAS) and dedicated access capabilities on a single and integrated platform. The E-series routes runs on JUNOSe software compared to other series of routers of Juniper which runs on JUNOS.
PAROLI is a proprietary protocol used inside a multi-shelf Carrier Routing System from Cisco and stands for "parallel optical link."
Hewlett Packard Enterprise and its predecessor entities have a long history of developing and selling networking products. Today it offers campus and small business networking products through its wholly owned company Aruba Networks which was acquired in 2015. Prior to this, HP Networking was the entity within HP offering networking products.
