Ethernet VPN Brings Distinct Advantages over Its Predecessor

By: Mae Kowalke, TMCnet Contributor

Ethernet services delivery based on the control plane approach hasn’t changed for proven solutions such as MPLS/VPLS and PBB. Layer 2 flooding and learning as an approach to build the forwarding database is still necessary, but this has inherent limitations.

A new approach has emerged that brings many benefits over the control plane approach in the form of Ethernet VPN (EVPN). With EVPN, the control plane and data planes are abstracted and separated. A multiprotocol BGP (MP-BGP) control plane protocol carries MAC/IP routing information, and there are several data plane encapsulation choices.

Enterprise Service Gateways Help Operators Extend Their Mobile VPN Offerings

By: Mae Kowalke, TMCnet Contributor

The emergence of cloud computing and mobility, not to mention bring-your-own-device trend (BYOD), has introduced a strong need for mobile virtual private networks (VPNs). Yet, most operators are only able to offer mobile VPNs to larger customers since their fixed-line VPN infrastructure is often separate from their cellular infrastructure.

One solution to this problem, outlined in a recent TechZine article, Mobile VPNs for Enterprises of All Sizes, by Jan Vandehoudt, Principal Consulting Engineer and Patrick McCabe, Senior Product Marketing Manager, Alcatel-Lucent, is for mobile network operators to use an enterprise services gateway (ESG).

Ethernet VPN (EVPN) - Networks for Ethernet Services

By: Greg Hankins, Senior Product Line Manager, Alcatel-Lucent

I’ve been talking a lot about EVPN recently at network operator conferences around the world, because I’m really excited about this new technology.  EVPN offers an alternative to VPLS that integrates both Layer 2 and Layer 3 services, and can run over simple IP networks with ECMP for resiliency and load balancing.  EVPN is an interesting new technology if you are providing a Layer 2 infrastructure over multiple sites, delivering integrated Layer 2/Layer 3 services, or providing cloud services.
