Dynamic Multipoint Virtual Private Network. Dynamic Multipoint Virtual Private Network (DMVPN)[ 1] is a dynamic tunneling form of a virtual private network (VPN) supported on Cisco IOS -based routers, and Huawei AR G3 routers, [ 2] and on Unix -like operating systems.
Ethernet. The Point-to-Point Protocol over Ethernet ( PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP 's IP network, and from there to the rest of the Internet.
The Link Layer Discovery Protocol ( LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network based on IEEE 802 technology, principally wired Ethernet. [ 1] The protocol is formally referred to by the IEEE as Station and Media Access Control ...
In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point (WAP). The splitter is the silver and black box in the middle between the wiring junction box ...
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
A Virtual Hub is the software-emulated virtual Ethernet switch. It learns and maintains its own forwarding-database table inside. While traditional physical Ethernet switches implement this function by hardware, SoftEther VPN implements the same function by software. A VPN Server can have several Virtual Hubs. Each Virtual Hub is isolated.
The inside of a Cisco 1900-series switch. 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.
