Operating in the carrier space for longer than I care to admit (hint – it was before internet and email were common!) I have worked for, and competed against, carriers that told clients they operate a private network. What does that really mean? Private to me means no one else, unless you say it’s OK. Private to the carriers means you, and anyone THEY say is OK. Huge difference!
A truly private network means no one else is using it unless you’ve approved it. This switches the authority over the network from Big Brother carrier to the people paying for the service. Makes sense. Only your companies data and voice packets travel the connection, especially between your corporate sites, if there are more than one. It is fully under your control.
The typical carriers idea of private means you, and anyone THEY determine are Ok, can use the network. The shift is back to the carrier and you lose control. The problem is most carriers have thousands, if not millions, of customers using this ‘private network’ all still competing for resources, even using private IP addresses. Depending on the network design and carrier investment, this could result in slower than advertised bandwidth speeds or security issues since all the client traffic is sharing the same network with other customer traffic. If you’ve ever experienced a carrier network issue and felt powerless to resolve it, you’ve been there. Doesn’t sound too private to me and seems like you’re paying for a service you literally have no power or control over!
The only true private network is one that keeps all your voice and data separate from any other packets from any other sources until it needs to traverse the public internet or Public Switched Telephone Network (PSTN). If you desire, or require, a true private network which YOU control, let us tell you how some of the largest area firms with the highest level of security needs did it.
