Ethernet, IP VPN or ATM you decide

Do you need control over your network or would you prefer to leave it in someone else's hands?

IP VPN

IP VPN is a managed service, so it would suit your organisation if you don't have in-house expertise or resources to control your own networks. Costs will typically be higher than for Ethernet, and you will be reliant on your provider for its efficiency, security, reliability and scalability.

However, IP VPN will benefit your organisation if it has a large number of small sites, or home or mobile workers who gain access to the network via dial-up or DSL.

ATM

ATM is an established WAN technology. ATM has long been standardised. It offers effective interconnections to ensure global reach and connectivity with partner suppliers keeping the consistency of all features regardless of access technology or partner used. The related quality of service and bandwidth is guaranteed for each permanent virtual circuit (PVC).

Ethernet - Total control

If your company has decided to self-manage and you have made a significant investment in your own technology, Ethernet is the way to go. It gives you total control over your network, with a level of features and services that is evolving to match those of IP VPN.

It's possible to have the best of both worlds. Combine the speed and flexibility of Ethernet for core sites, such as data centres and head offices, with the ability for IP VPN to effectively deliver a more distributed, lower bandwidth service to multiple offices and home workers.

Cheaper, simpler, high speed connections

You should consider an Ethernet WAN based solution if you're commissioning new infrastructure, expanding your presence within the market, or seeking to upgrade existing ATM connections.

Your LAN is based on it. Ethernet interfaces are usually cheaper than those for ATM. Creating a WAN solution using Ethernet means the interface is simpler to introduce and manage. The equipment and protocols are the same which leads to a reduction in specialist resource needed to deliver high-speed connections for you to do business.

This means lower up-front investment costs and lower running costs.
