And we come to SD-WAN

 width=When I first laid my hands on a computer in the early Eighties, I didn’t realize at the time the full magnitude of what I was looking at. From then on, the interest in technology was never to end. Soon, personal computers (PC), with their colorful screens and countless possibilities, would start to be popularized among residential users and businesses starting to put their new equipment to work to improve productivity and unlock new possibilities.

Then, there would come a time where devices would no longer work alone but be connected in networks. One of the most popular services in the beginning was the bulletin board system* (or BBS). This was a system that allowed users to use a fixed telephone line for so-called “dial-up” connections to simple remote networks with a few services. These connections gradually got faster, which in turn improved the user experience. When the World Wide Web (WWW) emerged, it brought with it another revolution. This one relied on users interacting with colorful graphic interfaces. And with the advent of ADSL, users were able to experience a new era of speed that was constantly increasing, as well as all kinds of online possibilities.

Lots of popular services came to the market, including ICQ, IRC, games, and so forth. So, it was a time in which we went from very low speeds to broadband with its development and improvements.

Businesses which stood to benefit from these changes started to deploy networks that were at once complex, robust and difficult to maintain, but that could take advantage of interconnected services like banking, electronic commerce and the wealth of new possibilities. ISDN, frame relay and ATM connections were widespread and would be extremely important to these companies for a long time (frame relay in particular had a lot of staying power).

The development of broadband technology and its applications gave rise to new companies specializing in offering Internet services. Telephone companies adapted to provide the interlinked network services, and all kinds of added services, such as voice services and MPLS networks, which while expensive, were what the market needed at the time.

So, mass deployment started among residential users and companies discovered an opportunity to remove some of their expensive MPLS links by replacing them with lower cost connections (such as ADSL) in many services – as seen, for example, in ATMs. The complexity and costs associated with installation, configuration and maintenance are also usually important for companies, together with the security that must be maintained whenever a change occurs in a company’s environment.

It is important to mention that, in addition to this cost-cutting movement, 3G/4G connections enabled companies to move a step closer to making the switch from pure MPLS networks to networks where all types of interconnections can be used, while basically maintaining secure connections and ensuring a high level of service availability.

All this complexity, together with the growing concern for keeping the environment safe, poses a challenge for companies when it comes to deploying and maintaining these networks. To solve this problem and create disruption in this highly complex and increasingly costly environment, we now find ourselves facing yet another major change in the marketplace – the introduction of SD-WAN. SD-WAN is ready to meet the evolving marketplace and new company needs. SD-WAN is a technology that gives businesses the ability to comply with digital transformation – which is now vital. With SD-WAN you can reduce costs, make your network more efficient, deploy new applications, enjoy increased control and much more.

Teldat’s SD-WAN provides all of this. It is a solution to help organizations manage their networks by simplifying their implementation and even their ongoing maintenance. The solution also integrates different operators and technologies in order to prevent traditional WAN networks from becoming obsolete.


A Bulletin Board System (BBS) is a software program that was popular for computer networks in the U.S. in the 80s and 90s because it allowed participating users to use a telephone line to connect to a network where they could view and consult a variety of data posted by other participating users.
