Private Point to Point Connections
Author: John SheplerSometimes you need to direct traffic from point A to point B in the safest and most transparent way. Let's take a look at some popular options for doing this.
What is a leased line?You can think of a dedicated private line as a connection between two sites that goes through a carrier. This is what you need when you can't easily run cables between buildings on your campus. A private line works like your own cable, except it's provided by another company. Private lines can cross cities, between cities or even across the globe
T1 leased line
T1 lines are the digital equivalent of the old "dry loop" or "tuned loop" that telephone companies lease to radio stations and intruder alarm companies. A dedicated T1 point-to-point line connects the two sites using twisted pair telecommunications cable. You will need a router or other device with a T1 interface on each end.
Dedicated T1 lines provide 1.5 Mbps in both directions with no usage restrictions. A popular application is audio transport, such as b. Studio-Transmitter Link (STL) for radio stations.
Dedicated T1 lines are still used for mobile traffic returns. These were very common before 4G LTE, which really required more bandwidth than T1. In some cases, multiple T1 lines can be tied together to create a higher bandwidth solution. Where optical fiber is not available, speeds of 10 or 12 Mbps can be achieved over a bonded T1 line.
Dedicated to DS3
In traditional TDM telecommunications circuits, the next step is a T3 or DS3 leased line. It offers private connection with 45 Mbit/s upload/download. DS3/T3 is considered a copper-based service. In practice, most transmission links are carried by OC3 or other SONET fiber optic circuits, with only the edge connection made by two coaxial copper wires.
Ethernet over copper
Ethernet over Copper (EoC) is a technological improvement over T1 when using the same peer-to-peer infrastructure. EoC easily scales bandwidth in the 1-10 Mbps range, and some systems provide speeds of up to 50 or even 100 Mbps over relatively short distances. If available, you may be able to replace EoC connected T1 solutions or DS3 circuits for significant savings.
Special fiber optic lines
Demand for greater bandwidth is increasing. Fortunately, private fiber optic lines are cheaper than in previous years. There are two interesting technologies, although they may not make much of a difference to the performance you choose. SONET is an older telecommunications standard with services such as OC3, OC12 and OC48 offering different bandwidth options. Fiber Ethernet is a technological upgrade from SONET. It offers easy scalability from 10 Mbit/s to 10 Gbit/s or more and is generally a more cost-effective solution.
Virtual Private Path
The Internet offers an inexpensive solution to connecting multiple sites, but it is neither private nor private. The attractive value comes from the fact that it is a shared resource with universal connectivity available almost anywhere in the world. There is little you can do to share bandwidth without allocating it for your own use, which can affect your application's performance. Lack of privacy can be overcome by encrypting your traffic, creating a private "tunnel" or VPN through the Internet.
MPLS networks offer a more robust solution. It can be thought of as a private version of the Internet, connecting only businesses and not the general public. A proprietary protocol is used to route network traffic, increasing communication security. MPLS networks are often referred to as MPLS VPNs. Network capacity and efficiency are actively managed by the network operator to allow the common core network to function as a private line. For long distances, MPLS offers significant cost savings compared to dedicated copper or fiber connections.
