Global MPLS IP VPN Services Market By Service (Layer 2, Layer 3) By Application (Automated Machines, Video Conferencing, Audio Conferencing) Expected To Reach USD 46.26 Billion by 2020: Grand View Research, Inc.
Mar 20, 2005 · Layer 2 VPN Architectures is a comprehensive guide to consolidating network infrastructures and extending VPN services. The book opens by discussing Layer 2 VPN applications utilizing both AToM and L2TPv3 protocols and comparing Layer 3 versus Layer 2 provider-provisioned VPNs. Layer two VPN Making use of Enhanced 802.1Q Tunneling. 802.1Q tunneling allows support organizations to supply a Layer two VPN service, often referred to as Layer 2 transparent LAN products and services (TLS) or Ethernet LAN products and services, using a VLAN-in-VLAN hierarchy and marking the labeled packets. L2TP stands for Layer 2 Tunneling Protocol, and it doesn’t provide any encryption by itself. L2TP VPN usually uses an authentication protocol, IPSec (Internet Protocol Security), for strong encryption and authentication, which gives it an ultimate edge on some other most used protocols like PPTP. The L2TP protocol uses UDP ports 1701. Virtual Private LAN Service (VPLS) is a pseudowire (PW) based, multipoint-to-multipoint layer 2 Ethernet VPN service provided by services providers By deploying a VPLS service to customers, the operator can focus on providing high throughput, highly available Ethernet bridging services and leave the layer 3 routing decision up to the customer. Layer 3 VPN (L3VPN) is a type of VPN mode that is built and delivered on OSI layer 3 networking technologies. The entire communication from the core VPN infrastructure is forwarded using layer 3 virtual routing and forwarding techniques. Layer 3 VPN is also known as virtual private routed network (VPRN). This two-day course is designed to provide students with MPLS-based Layer 2 virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS Layer 2 VPN concepts, such as BGP Layer 2 VPNs, LDP Layer 2 circuits, FEC 129 BGP autodiscovery, virtual private LAN service (VPLS), Ethernet VPN (EVPN), and

Designing and Implementing IP/MPLS-Based Ethernet Layer 2 Virtual Private LAN Service (VPLS) is a pseudowire (PW) based, multipoint-to-multipoint layer 2 Ethernet VPN service provided by services providers By deploying a VPLS service to customers, the operator can focus on providing high throughput, highly available Ethernet bridging services and leave the layer 3 routing decision up to the customer. draft-ietf-opsawg-l2nm-00 - A Layer 2 VPN Network YANG Model This YANG module provides representation of the Layer 2 VPN Service from a network standpoint. The module is meant to be used by a Network Controller to derive the configuration information that will be sent to relevant network devices. The L2NM YANG Data model complements the Layer 2 Service Model (RFC8466) by providing a network-centric view VPN vs MPLS: What’s the Difference? | FS Community
