Back up your MPLS network with an internet VPN
I was asked the other day during one of our webinars, whether an internet VPN ( Cisco, Watchguard, Sonicwall, etc.) can be used to provide redundancy for an MPLS network. The answer is yes. This provides a very cost effective backup for your wide area network. With very temporary usage, it becomes viable to utilize low cost broadband […]
Will IPv6 ever catch on?
There’s no business incentive to upgrade to IPv6, the next generation Internet protocol, according to a survey of network operators conducted by the Internet Society (ISOC). The report by the ISOC says that ISPs, enterprises and network equipment vendors report that there are “no concrete business drivers for IPv6.” However, survey respondents said customer demand for […]
What are the biggest challenges installing an MPLS network?
While the implementation of an MPLS can be complex, it really doesn’t have to be. If you keep the following factors in mind, you will have smooth sailing: 1. The first thing to realize is that you will need to extend the demark from your building telephone closet/room to your computer room. Some carriers will extend this […]
MPLS & VPLS Security
MPLS and VPLS networks are assumed to be secure. But the fact is, unless you use encryption, there is always the slight potential of security issues. Your network shares the PE device with other customers. Enno Rey, a respected network security consultant, based in Germany, has run significant testing and presented this subject at conferences. As […]

What will the latency of my network be?
One very interesting part of being an independent MPLS consultant is having the opportunity to view the ping time of identical networks at the time of migration from one carrier to another. It is the only time to obtain empirical measures of latency between different locations on a network. This data is invaluable to our work. When […]
Tagging packets for Class of Service
When you have an MPLS network, there are a few ways that your traffic is divided for Class of Service treatment. One common approach is at the carrier edge router. Another approach, is based on tagging at your own network using DiffServ, which is then picked up by the carrier edge router. DiffServ can support up to 64 […]
When you don’t need MPLS
I spoke with an IT manager at a five location business last week. They are presently networked to the HQ with a frame relay network. They received a quotation from AT&T, their local provider and wanted to do a “sanity check” of the pricing that their rep provided. After a series of probing questions, I […]
Networking to India – What Tier is your city?

This is why we always suggest the best carriers, based on our experience, can respond in a week or so. The service level agreements that you […]
Why is bandwidth so expensive in Latin America?
Clients that ask us for network connectivity in South America are usually surprised at the prices for internet connectivity and MPLS networking to Brazil, Argentina and other countries in the southern hemisphere. The primary cost driver is the limited subsea cables connecting South America to North America and Europe. Think of your college economics: supply and demand. […]
