Is a point to point t1 better than frame relay?

Big advantage over Frame Relay point-to-point is that allows you only need one connection from each site that allows you to relate to all areas. For example, if I have 4 offices that we all must be connected to one another (called meshed network), I need a circuit 6. However, frame relay, I only need 4. Frame Relay allows me to work with 1 / 3 minority Circuit. Plus a user can also connect the Internet to accommodate the PVC the SECOND LAN / Wan networks and Internet bandwidth needs in a single network architecture.
When buying Frame Relay, PVC Bandwidth user choose which to buy. This is a fixed data rate, or bandwidth, which they possess. Users can also choose burstable bandwidth / data rate. Burstable means that as needed basis can explode quickly, and only pay for extra bandwidth, especially when its use.
One example of this is that the client has a need for a sustained 512 kbps Bandwidth parts. Plus, once a month is a back-up all data from all the major sites, which require explosion 1.544 Mbps for a few hours to complete the data transfer. In the step-by-point service, the client will be forced to buy the 1.544 Mbps bandwidth in all fields, even if it will be fully utilized only once every month. For this reason and the same type, Frame Relay has become the dominant type of data services for business communications for years.
Similarly, the client needs? Would depend on several things, but most (1) how many areas need to network, and (2) what types of communication they want to use the internet. Today, very few companies see the implementation of Frame Relay unless they are already in place. New equipment is usually a choice between MPLS and Carrier Ethernet option. I do not look extensively about this the other two in this post, but suffice to say that if the client has only two or three areas and they can either point-to-point, or simply connect through the Internet and using Internet-based applications for complete their voice and data communications. If they have more areas, I gnficiant bandwidth requirements, and / or desire for voice, data and video communications between locations, they are likely MPLS is better, mainly because of MPLS will allow them to control the quality of care, which is when many critcal mixed utilizing the services, and real-time services like voice and video.
Laymens issues ..... I ll try to simplify even more.
1. And point to point connection you have to pay for the relationship between the two points. You can pay a fixed fee for a year and a relationship, or a month. There are several variables that affect the cost.
A) How far apart are two points
B) Are connecting several telecommunications operators or service points from one
C) Are the various points in the City, United States, Country, Continent
D) What do you want to be a close relationship
E) Do you want a relationship is always available or only available on request (such as ISDN or even dial-up --- they all offer point to point, only tempoary)
2. With Frame Relay, or MPLS or ATM, or some system of relations with .... You've just bought the last mile of your relationship ends, when you share among other users. You can pay your network operator to separate traffic into the center (usually described as a cloud, an abstract concept, the network provider you can apply whatever way they need) and provide guaranteed bandwidth. Some airlines will sell you the ability to assess the burst may sometimes (but not always) broadband speed on the use of needs. Your relationship with the low speed and low-or last-mile connection speeds at both ends or the amount you still purchased from the carrier. Carrier will use the name as Cir, Developing Information Rate described the level you have purchased.
A) The distance does not really determine the price
B) What connects several operators or a single telecommunications operator points (you still pay the claim two miles last modified on ends)
C) Are the various points in the City, United States, Country, Continent (tariffed may affect the price and taxes, plus controls)
D) What do you want to be a close relationship
E) you usually pay for is always a connection, called a permanent virtual circuit. You really only eat when the network resources to send data but always there for you soon.
3. Finally you can stop paying full center by using Virtual Private Networks on the Internet. In this case you still have to pay for access to both sides, but there is no center to pay. No doubt there are some advantages:
A) Because there is no guarantee the center, you are on your own to support and troubleshoot it
B) You will comingle traffic public Internet traffic. It's up to you to ensure that it is safe. You can do this by hiring respected cryptographic protocols and strong encryption keys used.
In short, Point to Point is to ensure better data, but Frame Relay is more cost effective. Needs analysis is what will determine the real need for one another, and have explained the ROI (Return on Investment) for all application requirements are defined. For help in working through this analysis to find a solution for you .... I recommend using free assistance is available via DS3-Bandwidth.com.
