It is a point-to-Point T1 Better Than Frame Relay?

Frame Relay is a communications protocol. His name as it provides data and information needed in order to communicate properly in a "frame", which consists of different areas. Provides data to be transmitted, surrounded by four other fields, information about where the data frame should contain and how it should be treated in a particular area. A user has installed dedicated lines to the sites, the frame relay network to connect to their carrier. Then theUses vector, which transmit a "permanent virtual circuit" or "PVC" for the data within the network announced.

The main advantage is over Frame Relay point-to-point, which allows only need to connect from anywhere, so you can be connected to all sites. For example, if I have 4 offices, each of them (called a network "mesh" ") must be connected, I would need six circles. But with Frame Relay, Frame Relay, I need only 4 allows me to do this work with 1 / 3fewer circuits. In addition, a user can also be a PVC using the Internet to integrate both the LAN / WAN network and Internet bandwidth to be on a network architecture.

When you buy from Frame Relay, you must select the bandwidth of the PVC that buys it. This is the "fixed" data rate or bandwidth they have. You may also have a "burstable" bandwidth / frequency data. Burstable means that may be on an as-needed "burst" at a higher speed, and only payfor the bandwidth when you actually use.

An example of this is that a customer needs is a normal course for 512 kbps of bandwidth between the sites has. In addition, once a month, back up all data from any point on the main page that requires a "burst" of 1.544 Mbps for a few hours to reach the data transfer. In a point-point, the customer would be forced to buy 1.544 Mbps of bandwidth for all locations, even though it was only at full capacity once a month.For these and similar reasons, Frame Relay, the dominant mode of data communications service for business customers for many years.

So what does a customer? Depends on a number of factors, but mainly (1) how many seats they need to network and (2) what types of communication they want to use the network. Today, very few companies on the implementation of Frame Relay, unless we find it already in place. New plants are usually the choice between MPLS andCarrier Ethernet options. I will not try to deepen the other two services here in this post, but suffice to say that if a customer has only two or three sites, they can go well with the point-to-point, or simply a connection via the Internet and Internet-based applications to meet their voice and data communications. If they need to perform multiple positions, signficiant requirements of bandwidth, and / or the desire for voice, data and video between locations, are more likelyMPLS better, especially because it allows them MPLS Quality of Service, which is the most be a factor when working with mixed services and real-time services like voice and video control.

In lay terms ..... I will try to simplify it further.

1 With a point to point connection that you pay for a connection between two points. You pay a commitment rate for this connection, per year or per month. There are several variables that affect the cost.

A) What is the distance between thecolon
B) There are several telecommunications companies to connect the dots or simply a vector
C) If the points are in different cities, states, countries, continents
Q) How fast you want to connect
E) the connection you want to always be available or if available (such as ISDN or dial-up --- are both versions point to point, furnished only required)

With 2 Frame Relay or ATM, or MPLS, or any other number of connecting ordinary .... TheirBuy only '"last mile" connection at both ends, while sharing the center with other users. You pay your operator to separate the traffic within the center (usually as a "cloud" is described as an abstract concept, the system operator can implement any case it is needed) and provide guaranteed bandwidth. Some airlines to sell the ability to "blow up" the speed is higher, so that sometimes (but not always) can use higher speeds inQuestion. The connection speed is the lowest among the "last mile" connection speed at each end or with a special course you are limited by the carrier purchased. The carrier will be described with a name like CIR, Committed Information Rate the speed with which it was purchased.

A) removal is not a determinant of the price
B) There are several telecommunications companies to connect the dots or just a support (you have to pay the costs of last mile even on both ends)
C) If the points are in different(The price is likely to affect prices and taxes, as well as regulatory) cities, states, countries, continents
Q) How fast you want to connect
A) In general, you should always pay for a connection, called a permanent virtual circuit. It is really only consume network resources when data is sent, but it is always there for you immediately.

3 Finally, you can pay for the part in the middle completely through virtual private networks over the Internet. In this case, you canto pay more for access to both sides, but no one pays for the middle class. There are also some disadvantages:

A) Because no one providing the means, you are alone to support and secure
B) the traffic is comingle with Internet traffic. It is up to you to ensure that it is safe. They do this by using an encryption protocol greatly appreciated and a very strong first key.

In short, to ensure the best data point by point, but Frame Relaycost-effectiveness. Analysis of what the requirements are determined, the actual need for a comparison with the other and set the ROI (Return on Investment) for the application requirements defined once. To help find work through this analysis for the right solution for you .... I suggest using the free support receive DS3-Bandwidth.com.
