Which Ethernet solution is right for your multi-site enterprise?

 A quick reference guide for making the right connection


Deploying an enterprise data solution like multi-site Ethernet optimizes your network with secure, low-latency Layer 2 connections. But which multi-site Ethernet network topology is right for your business? Well, it all depends on the number of locations and desired traffic pattern. Here’s a quick reference guide to help you find the right enterprise-grade multi-site Ethernet solution for your requirements.

Connect two locations


Consider an Ethernet Private Line (EPL) which allows both locations to communicate seamlessly while supporting Layer 2 control protocols like Spanning Tree Protocol (STP).


EXAMPLE: A mid-sized manufacturing company deploys an EPL to connect its headquarters to its warehouse.

Connect three or more locations in a hub and spoke configuration


Consider an Ethernet Virtual Private Line (EVPL), which ensures communication only takes place between a hub and spoke, never between two spokes.


EXAMPLE: A hospital network deploys an EVPL to connect each outpatient location to the electronic medical records software at headquarters, but not to each other.

Connect three or more locations in an any-to-any configuration


Consider an Ethernet Private Local Area Network (EP-LAN), which provides a fully meshed network topology solution for enterprises migrating from Multiprotocol Label Switching (MPLS) VPN and other technologies. With full mesh, this solution yields the greatest amount of redundancy so if one of those nodes fails, your network traffic can be directed to any of the other nodes.


EXAMPLE: A large enterprise with distributed resources across its footprint deploys an EP-LAN so each location can access resources on demand.

Connect three or more locations while integrating other services


Consider an EVP-LAN (Ethernet Virtual Private Local Area Network), which combines the benefits of a fully meshed network solution with the ability to integrate additional services like Ethernet Internet Access (EIA) and IP Connect via Service Multiplexing at the UserNetwork Interface (UNI), a bidirectional point for Ethernet service delivery.


EXAMPLE: A school district requires two separate wide area networks (WAN) for voice and data, so an EVPL and EVP-LAN are combined at the headquarters UNI to hand off on a single port.
