Advantage of Dedicated Cloud Connections

The capital investment and staff cost savings offered by cloud services are encouraging small, medium and large companies alike to move their telephone and IT resources to the cloud. It’s been assumed that a simple broadband Internet connection will suffice for access. That’s turning out to be a disappointment in some cases.

The notion that bandwidth is bandwidth is how we get in trouble specifying metro and wide area network connections. What makes the Internet attractive as a WAN service is that it is almost universally available and the cost is spread over millions, even billions of users. Savvy companies discovered long ago that you could get around the security issues by encrypting your data to create a VPN or Virtual Private Network. The VPN gives you a private tunnel through a public network.

VPNs work great to support remote workers and traveling employees who’s only way to connect with corporate headquarters is through a wired or wireless Internet service. They’re also good for linking multiple business locations, such as branch offices or franchises. With a VPN you can transfer sensitive financial and inventory files among dozens, hundreds or thousands of locations.

Note that we are talking about file transfers. The TCP/IP network protocol was made for this application. All you do is launch the transfer and TCP will ensure that all the packets that make up the file will get from point A to point B intact. If something goes awry and a packet is corrupted, it is automatically resent.

Remember that the Internet was designed for universal access and to be self-healing in the face of equipment failure or line breaks. While TCP/IP is making sure that files are being accurately transfered, the Internet itself is making sure that there is a path available from point A to point B no matter what. While you can expect to transfer data, voice or video files over the Internet, you can’t really expect that this is going to happen without hiccups or in any minimal amount of time. Packets may or may not be lost and require a resend. The path may change from packet to packet. The latency or time delay from source to destination can vary all over the place, or jitter.

The result of this is that real time performance of Internet connections is highly variable. This is no big deal for data file transfers. The time to transfer may vary by milliseconds or seconds for each file. Time sensitive data streams like audio and video need some extra help in the form of buffering. You compensate for unknowable transmission rate variations by filling up a buffer with packets and then clocking them out at a constant rate.

Buffering works great for one-way downloads, but creates havoc for real-time video or audio streams. That includes telephone calls and video conferencing. You can’t have much of a buffer or the latency increases to the point where you can’t talk and listen at the same time. There is a noticeable delay, fractions of a second or longer, that make two-way communication painful at best. Lost packets from iffy Internet connections add distortion that blurs your video and garbles your audio.

The same Internet that seems fast and responsive when searching for information on Google can be maddening when trying to calm down an angry customer on a VoIP phone call that is breaking up. Automated business processes that worked fine over the LAN when the data center was in-house all of a sudden become sluggish in the cloud. It’s not that the cloud isn’t just as good or better than local resources, it’s that you need a better connection.

What you want is a dedicated connection between you and your cloud provider. Level 3 Communications is now offering dedicated connections to Amazon Web Services (AWS) running in Equinix data centers to meet the demand from larger corporations. Dedicated connections include Ethernet Private Line, Ethernet MPLS and Wavelength services. T1 lines are also suitable for smaller companies, although Ethernet over Copper may be a lower cost option and offer more bandwidth for the money.

A dedicated connection ensures that you have steady guaranteed bandwidth plus low latency, jitter and packet loss. Security is also improved because access is limited, not publicly available. A well engineered dedicated connection is just like a very long LAN that includes your locations and your service provider.

Are you disappointed with the performance of your cloud services or concerned that quality will suffer if you move from a local data center to the cloud? All you may need to get things working to your satisfaction is a high quality dedicated cloud connection. Why put up with all that aggravation when dedicated connection prices are lower than they’ve ever been? Check prices and availability of dedicated cloud connection bandwidth you need to support your critical applications.

Ethernet Exchange For Miami, Dallas and Los Angeles

It’s becoming increasingly apparent that the replacement for the Public Switched Telephone Network may well be Carrier Ethernet. More evidence for this is the expansion of Ethernet Exchanges that allow carriers to transport each other’s traffic. Telx, a major colocation and interconnection service company, has just added Miami, Dallas and Los Angeles to its suite of Ethernet Exchange facilities nationwide. Let’s take a look at why Ethernet Exchange matters and how it influences the direction of international wide area networking.

The century long dominance of the PSTN or Public Switched Telephone Network can be attributed to its universal acceptance. Every phone can connect to every other phone in the world and work correctly. This network has been adapted for data and well as voice service for worldwide connectivity. It’s a circuit switched rather than packet switched network, but with proper interfacing and protocol conversion it gets the job done.

Another model of universal connectivity is the Internet. The Internet is an IP network that is based on packet switching rather than circuit switching. Isn’t the Internet the model to emulate for the next generation in commercial connectivity?

Actually neither the PSTN nor the Internet are ideal for high performance network services. The PSTN has a telephone legacy and is organized around small independent channels bundled together to create larger amounts of bandwidth. It’s also a different set of protocols than are running on a majority of the world’s data networks. The Internet was designed by the government for survivability in the event of war or natural disaster. As such, it’s so autonomous that routes can change spontaneously and there is no such thing as class of service or guarantee of bandwidth, jitter, latency or packet loss.

Carrier Ethernet seems like the ideal protocol for today’s metropolitan and long haul networking. After all, the network most likely to need transport is running Ethernet in the LAN. More and more, that’s converged voice, data and video over Ethernet. When you go to the trouble of carefully engineering your internal networks, it only makes sense to expect to link those networks transparently.

The only fly in the ointment has been network reach. The companies most active in deploying Carrier Ethernet services have not had protected monopolies like the old telcos nor government R&D like the Internet. These are commercial companies, some with legacy telco assets and some with all-new IP core fiber optic networks. While each competitor may have thousands of buildings on-net, nobody blankets the Earth.

Here enters the Ethernet Exchange. The idea is a facility that enables Ethernet network operators to exchange traffic. By doing this, each carrier increases the reach of its network into the footprint of other carriers. Even Ethernet Exchanges can partner. Telx has a partnership with Neutral Tandem to provide access to each other’s exchange locations.

With demand for Ethernet services growing rapidly each year, cooperation benefits all parties involved in transporting high bandwidth Metro and Carrier Ethernet services. Ethernet connections are now available in metropolitan areas throughout the US and in many countries around the world. The cost advantage, scalability and portfolio of services available with Ethernet is working to establish Ethernet as the new WAN networking standard at the expense of legacy telecom services.
