Application Aware Routing is the dynamic selection of a route in a complex network in which several routes lead to the desired destination. In doing so, the choice of the best route is based on the application to be transported, and its demands on the quality of the available routes.
The Control Plane is the instance in a network and/or network element (e.g. router) which is responsible for controlling (routing) the connections. Against this background, it should be noted that state-of-the-art SD-WANs are characterised by a strict separation of the Data and Control Planes.
CPE stands for Customer Premise Equipment and describes the hardware used at the customer’s site to connect the Local Area Network (LAN) with the Wide Area Network (WAN). ngena’s SD-WAN solution primarily uses Cisco-Viptela hardware.
The Data Plane is the instance in a network and/or network element (e.g. router) which is responsible for transporting the actual data. Against this background, it should be noted that state-of-the-art SD-WANs are characterised by a strict separation of the Data and Control Planes.
Dedicated Internet Access is more of a business term than technology. It describes, that a specified amount of bandwidth - that was sold to a customer for his connection between the Internet and his sites - has really been assigned and is entirely dedicated for customer’s use (instead of best-effort connections in Broadband Internet connections.
EPL stands for Ethernet Private Line. “Ethernet is a wire-based data network technology that is used for Local Area Networks (LANs). It allows data interchange between any devices that are connected in a local area network (computers, printers, etc.). The standard originally involved LANs that extended over only one building. Nowadays Ethernet technology is meanwhile also used in Wide Area Networks (WAN) and makes it possible to link up devices over long distances (Source: https://www.telekom.com/en/glossary.
IPL stands for Internet Public Line and describes a connection and the transmission of data over the public Internet. Against this background, a distinction is made between “Broadband” and “Direct Internet Access” (DIA). Broadband Internet access is generally based on a consumer market product, such as xDSL or cable connections which are offered with accordingly low, or no, service level guarantees. DIA, by contrast, is a product for business customers and is based on a leased line with corresponding service level guarantees.
Network Health Dashboard describes a control centre that can be called up from a Web browser and shows the status of the network and its individual components (routers, switches, access points etc.). This includes e.g. the functional status of the CPEs, number of possible malfunctions, and network parameters such as bandwidths, jitter and loss etc.
Network Functions Virtualisation (NFV), is an overarching principle or concept. Network functions are no longer implemented as physical appliances (using closely-coupled software and proprietary hardware), but as software that is fully decoupled from the underlying hardware platform.
An Overlay is a logical network (in this case: the SD-WAN) which is superimposed on top of an existing infrastructure (Underlay). Overlay and Underlay are entirely independent of one another.
SDN stands for “Software Defined Networking” and describes a technology that uses software to control networks. Wide Area Networks which are controlled using this technology are known as SD-WANs (Software-defined Wide Area Networks).
Service Orchestration is a flexible mechanism used to combine individual software-based services and/or their components, as well as to deliver and configure these. Service Orchestration is generally automated.
Underlay is an existing infrastructure (e.g. the public Internet or a privates Ethernet), on top of which the Overlay network is superimposed. Overlay and Underlay are entirely independent of one another.
Virtual Network Functions (VNFs) are virtualised network functionalities which, in ngena’s SD-WAN solution, are automatically made available centrally via service orchestration mechanisms. This includes e.g. virtual firewalls and Web security in the Advanced Security Services space, and WAN optimisation possibilities in the Application Optimisation Services space.
Virtual Private Networks (VPN) a self-contained computer network which is set up on a public network infrastructure. Only communications partners that belong to this private network can communicate with each other and share information and data. VPNs are used, for instance, by companies with several locations to protect data traffic between the individual locations.” (Source: https://www.telekom.com/en/glossary).
Wholesale service “refers to the business of selling services to third parties who sell them to their own end customers either directly or after further processing” (Source: https://www.telekom.com/en/glossary). In connection with our SD-WAN offering, ngena provides the wholesale services which ensue from combining its alliance partners’ networks into a global SD-WAN by means of a central platform and SDN technology. The alliance partners then make these SD-WAN services available to their end-customers.
