Enterprise Backhauling

Enterprise Backhauling

This document presents the results encountered in a laboratory simulation for a common scenario ofa WISP network segment deployment (“Point-to-Multipoint” sector) with Pionaria Wireless units.

General overview

When discussing about the Enterprise sector, a specific terminology and topology must be prior defined. A common topology for a regional business expansion.

The Headquarter represents the main office or the nucleus of the business and it is usually the largest office, with the biggest number of employees

The Data center is the place where all the servers and company resources are stored. It can be alsoincluded in the headquarter premises and it must be accessed by all employees of the company at anytime and with accurate speed.

The Branch offices represent smaller business centers that can spread from shorter regional distancesto nation or world-wide distances.

There can be also employees that work from home, for example as remote workers/tele-workers.


Backhaul requirements

The variety of solutions available for the backhaul infrastructure can be confusing, but there are specific points of view to consider for each of them. The main options are:
Using a public solution: connections over the Internet together with VPNs and/or MPLS are still popular because of the low costs and flexibility, but in order to increase security, availability and control over the backhaul, the private owned solutions have a more important role Using a private solution: one option would be the leased lines, which are easy to maintain, stable, but represent the most expensive solution with very limited expansion capabilities. Another option, more suitable, is represented by the wireless segment, which has developed into a very cost effective and high performance solution.
