Advanced Networking Devices
- Out-of-brand Management - a function of marketing that uses techniques to increase the perceived value of a product line or brand over time
- Peer-to-Peer - denoting or relating to computer networks in which each computer can act as a server for the others, allowing shared access to files and peripherals without the need for a central server
- Point-To-Point Tunneling Protocol (PPTP) - an obsolete method for implementing virtual private networks. PPTP has many well known security issues. PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality
- Port Authentication -enables configuration of parameters for each port
- Port Mirroring - also known as SPAN (Switched Port Analyzer), is a method of monitoring network traffic. With port mirroring enabled, the switch sends a copy of all network packets seen on one port (or an entire VLAN) to another port, where the packet can be analyzed
- Proxy Server - sits in between clients and external servers, essentially pocketing the requests from the clients for server resources and making those requests itself
- Quality of Service (QoS) - the description or measurement of the overall performance of a service, such as a telephony or computer network or a cloud computing service, particularly the performance seen by the users of the network
- Reverse Proxy Server – acts on behalf of the servers
- Routing and Remote Access Service (RRAS) - a Microsoft API and server software that makes it possible to create applications to administer the routing and remote access service capabilities of the operating system, to function as a network router. Developers can also use RRAS to implement routing protocols
- Site-to-Site - a type of VPN connection that is created between two separate locations. It provides the ability to connect geographically separate locations or networks, usually over the public Internet connection or a WAN connection
- SSL VPN – Secure Sockets Layer Virtual Private Network
- Traffic Shaping - bandwidth management technique that delays the flow of certain types of network packets in order to ensure network performance for higher priority applications
- Trunk Port – a port or switch configured to carry all traffic
- Trunking – process of transferring VLAN traffic between two or more switches
- Virtual Local Area Network (VLAN) – segments networks using owned switches
- Virtual Private Network (VPN) -
- VLAN Trunking Protocol (VTP)
- VPN Concentrator – VPN-capable router
