  2. Layer 2 MPLS VPN - Wikipedia

    en.wikipedia.org/wiki/Layer_2_MPLS_VPN

    Logical View of a Layer 2 MPLS VPN. A Layer 2 MPLS VPN is a term in computer networking. It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network. This is often sold as a service to businesses. Layer 2 VPNs are a type of Virtual Private Network (VPN ...

  3. MPLS VPN - Wikipedia

    en.wikipedia.org/wiki/MPLS_VPN

    MPLS VPN is a family of methods for using Multiprotocol Label Switching (MPLS) to create virtual private networks (VPNs). MPLS VPN is a flexible method to transport and route several types of network traffic using an MPLS backbone. There are three types of MPLS VPNs deployed in networks today: 1. Point-to-point 2. Layer 2 (VPLS) 3.

  4. Multiprotocol Label Switching - Wikipedia

    en.wikipedia.org/wiki/Multiprotocol_Label_Switching

    MPLS LSPs provide dynamic, transparent virtual networks with support for traffic engineering, the ability to transport layer-3 (IP) VPNs with overlapping address spaces, and support for layer-2 pseudowires using Pseudowire Emulation Edge-to-Edge (PWE3) [29] that are capable of transporting a variety of transport payloads (IPv4, IPv6, ATM, Frame ...

  5. Ethernet VPN - Wikipedia

    en.wikipedia.org/wiki/Ethernet_VPN

    Ethernet VPN (EVPN) is a technology for carrying layer 2 Ethernet traffic as a virtual private network using wide area network protocols. EVPN technologies include Ethernet over MPLS and Ethernet over VXLAN. [1] [2] EVPN uses encapsulation methods to ensure efficient and scalable transmission of Ethernet traffic over MPLS or IP-based networks.

  6. Layer 2 Tunneling Protocol - Wikipedia

    en.wikipedia.org/wiki/Layer_2_Tunneling_Protocol

    In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It uses encryption ('hiding') only for its own control messages (using an optional pre-shared secret), and does not provide any encryption or confidentiality of content ...

    Its IPv6-capable backbone network leverages softswitches (the control layer) and protocols like DiffServ and MPLS, which boosts performance of the bearer layer. The MPLS-optimized architecture also enables Frame Relay and ATM traffic to be transported over a Layer 2 VPN, which supports both legacy traffic and new IP services over a single IP ...

  9. Overlay network - Wikipedia

    en.wikipedia.org/wiki/Overlay_network

    The limited deployment of IP Multicast, a best-effort network layer multicast protocol, has led to considerable interest in alternate approaches that are implemented at the application layer, using only end-systems. In an overlay or end-system multicast approach, participating peers organize themselves into an overlay topology for data delivery.
