Nothing says that we are part of a global marketplace like the terabytes of data that zip back and forth constantly through the world’s fiber optic trunk lines. Intercontinental cables have been in place for decades. But now there’s a new service gaining importance. It’s low latency networks.
What’s driving the demand for low latency right now is high speed financial trading. Increased use of automated trading programs has created a competition for getting trades placed first. First may mean milliseconds or even microseconds ahead of other traders. Certainly this is beyond the capability of the fastest human traders manually entering data. But it’s also so fast that path between traders and exchanges influences performance. The time delay in that path is called latency.
What’s needed for low latency connections is minimizing the distance between source and destination and minimizing the processing time of the electronics in the network. When microseconds make a difference, the speed of light comes into play. The fastest a signal can go is about 186 miles per millisecond. That’s the speed of light in a vacuum. In a physical wire or fiber optic strand, that speed is even less.
In the United States, low latency network services have taken two forms. One is a fiber optic cable running in as straight a line as possible between trading centers, say Chicago and New York. The amount of equipment on that line is minimized and engineered to pass signals as fast as possible.
Another approach is colocation. Companies move into a colocation facility, such as the ones offered by Telx, to be as close to the electronic trading floors as possible. It’s possible to save tens of milliseconds by just being physically next door.
Level 3 Communications has now established low latency connections that span the Atlantic from Europe to North America. They’ve also established direct connectivity with BATS Europe, a European Multilateral Trading Facility.
Financial services are a leading application driving the construction of low latency networks worldwide. There are other applications that are latency sensitive as well. It’s well known that VoIP telephony works best if latency is minimized. Long delays in voice packets cause “clipping” of conversations and may even result in dropped calls. Two-way video conferencing is also affected by high latencies. In fact, any interactive application requires some limitations on latency to function properly. As companies commit more of their business processes to cloud computing, latency issues that were once non-existant will become painfully apparent.
Has your company or organization developed a need for low latency communications linking locations in North or South America, Europe, Asia, Australia or Africa? Find out what services are available to meet your requirements for international high bandwidth low latency network connections. With multiple providers, prices are competitive.

What’s exciting, compelling, and goes so fast you can hardly keep up with it?
How about NASCAR? Certainly true. But that also applies to the Samsung Intercept Android phone. Oddly enough, both are connected.
The Samsung Intercept M910 for Sprint is a dual phone. It has the large 3 inch touch screen display you expect in a smartphone. But it also has a slide-out QWERTY keyboard that gives you real keys large enough for efficient texting and other typing.
Yes, this is an Android phone. It runs Android 2.1. You can choose from thousands of apps from the Android market to customize this phone as your own.
What other goodies are included? How about a 3.2 Megapixel digital camera that takes high resolution still photos but also doubles as a video camera? It has that plus support for streaming media so you can watch live TV and video on demand with full motion video and vivid sound. Catch the latest news, sports, weather and entertainment while you are on the go with Sprint TV. Who wants a TV that’s tied to the wall anymore?
You can connect with colleagues, friends and family via text, email or instant message. You can listen to your voicemail in any order and manage your inbox without calling-in by using visual voicemail. You’ll also be connected to work with the ability to view Word, Excel and Powerpoint documents. Or just ignore them and face the wrath of your boss later. What you really want to do is tweet, and access to Twitter is built-in. So is Facebook access. I guess you really don’t have time to look at those Excel spreadsheets after all.
The Samsung Intercept has GPS services support for location-based services like Google Maps. It also sports a full HTML Web browser so you can surf the Web at will. But will you have enough speed to do so? You’ll will with Sprint’s 3G EV-DO data network. You can also save your minutes by using WiFi access when you are in a WiFi hotspot.
This all sounds great, but what’s the connection with NASCAR? Oh, that’s easy. NASCAR Sprint Cup Mobile instantly connects you to the world of NASCAR. Once you have that, other cell phones seem so.... s-l-o-w.
If this sounds like the smartphone you’ve been waiting for, learn more and order your Samsung Intercept for Sprint online, where it is free after instant discount with free shipping via FedEx included. You were going to stand in line at a cell phone store, why?
Of course, there are many other excellent cell phones available free and at deep discount. Check out Today’s Special Deals at Cell Phone Plans Finder now.

Metro Ethernet service has been growing by leaps and bounds. That’s not surprising, considering that Metro Ethernet services generally offer higher bandwidths at lower prices than traditional telecom services. They also offer features such as virtual private line and LAN service that weren’t previously available. As business appetite for Ethernet in the WAN grows, it’s only natural that businesses look to connect everywhere through their Metro Ethernet connections.
Metro Ethernet was intended to be just that. The "metro" in Metro Ethernet means metropolitan. It’s a service that is perfect for connecting two or more business locations within the same city or greater metropolitan area. The geographical range of coverage is set by the service footprint of the carrier providing the service.
Many competitive carriers now base their core networks on IP packet switching technology, not the traditional circuit switching architecture. They’ve embraced Carrier Ethernet to offer Ethernet services that span metropolitan areas so that companies can interconnect branches in cities across the country.
What’s been more difficult is getting the same type of universal access that companies have enjoyed with the Public Switched Telephone Network. After all, the days of monopoly in telecommunications are long gone. What’s needed is a standardized way for all those competing carriers to exchange traffic so that their customers can have a much wider geographical presence. Thats what E-NNI is all about.
The Ethernet External Network-to-Network Interface (E-NNI) is an industry standard ratified this year by the Metro Ethernet Forum. It provides a way for carriers to exchange traffic without having to worry about losing service features or having to create ad-hoc interfaces carrier by carrier. A separate UNI or User Network Interface connects each customer to its respective carrier.
The E-NNI specification makes it easy for carriers to exchange voice, data and video traffic at Ethernet layer-2. This make switched networks that span multiple carriers possible. To the user, the Ethernet WAN may look like one large cloud. To the service providers, it is a collection of clouds interconnected by peering through E-NNI connections.
The ratification of the E-NNI standard is giving rise to Ethernet Exchanges, such as Telx, that provide worldwide interconnection services for service providers at a carrier-neutral facility. Rather than having to build-out their service footprints to everywhere customers want connections or going through the laborious process of negotiating Private Ethernet NNI agreements, carriers can simply connect with each other through an Ethernet Exchange so that each participant has access to a much larger geographical footprint.
Can you company benefit from the growth of Carrier Ethernet and the many services it offers? The best way to find out is to get a competitive quote for your connection needs, be they across town or to the other side of the globe.
