Management has a fear that switching from AT&amp;T MPLS to a AT&amp;T Wired VPN soltuion will cause some speed/etc issues between our four locations which have a total of 300 users.<br />
<br />
At a previous employer we we did not have MPLS and used VPN to get to our remote ERP system.<br />
<br />
1. Do you know of anyone using VPN between locations ?<br />
2. If so, do they do VOIP between locations ?<br />
3. Do they use SoniceWall VPN hardware ?<br />
<br />
There is an old <a href="http://www.networkworld.com/reviews/2006/022006-ssl-voip-test.html" rel="ugc">http://www.networkworld.com/reviews/2006/022006-ssl-voip-test.html</a>&nbsp;article, but I would like more up-to-date articles.

MPLS vs VPN

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
