Which one of the following is an advantage of frame relay over leased lines?

Which one of the following is an advantage of frame relay over leased lines?

One major advantage of Frame Relay over Leased lines is its cost efficiency. Leased lines cost more since it is implemented on a per-port basis, meaning, each peer connection is a dedicated link; only the peer connected on each side uses the link.

What are the advantages and disadvantages of an asynchronous transfer?

Asynchronous Transfer Mode Advantages and Disadvantages At first, it offers high-speed, fast-switched integrated data, voice, and video communication. Secondly, it can replace the existing telephony networks infrastructure. Thirdly, it can interoperable with standard LAN/WAN technologies.

What is the difference between frame relay and MPLS?

MPLS is a private networking technology similar to the concept of Frame Relay in that it is delivered in the “cloud”. The primary difference with MPLS is that you can purchase quality of service for applications across your WAN. If an application works well on a Frame Relay, it will work better using MPLS.

What are the characteristics of Frame Relay?

Some important features of frame relay are :

• Frame relay operates at a high speed (1.544 Mbps to 44.376 Mbps).
• Frame relay operates only in the physical and data link layers.
• It allows the bursty data.
• It has a large frame size of 9000 bytes.
• Frame relay can only detect errors (at the data link layer).

What are the advantages and disadvantages of ATM?

Advantages and disadvantages of ATM

• Quick and prompt service is possible with less human errors.
• It is beneficial for travelers.
• It provides 24 hrs services without any staff and reduces the work load on bank staff.
• Withdraw cash at any time or in urgent without the help of bank.
• It ensures privacy to the customers.

What are the similarities between frame relay and ATM?

Asynchronous Transmission Mode (ATM):

S.NO	Frame Relay	ATM
6.	The throughput of frame relay is moderate.	While it’s throughput is high.
7.	Frame relay does not provide error control and flow control.	While ATM provides error control and flow control.

Why is Frame Relay more cost-effective than leased lines?

25. As a rule, higher connect times make leased-line solutions more cost-effective. Frame Relay service is often less expensive than leased lines, and the cost is based on: – The committed information rate (CIR), which can be exceeded up to the port speed when the capacity is available on your carrier’s network.

What are the advantages and disadvantages of synchronous and asynchronous communication?

Synchronous and asynchronous communication ANS: A benefit of synchronous communication is that it allows a rendezvous between the sender and receiver. A disadvantage of a blocking send is that a rendezvous may not be required and the message could be delivered asynchronously.

What are the disadvantages to asynchronous transmission?

Disadvantage of Asynchronous Transmission

• Start and Stop Bit Over heading.
• Noise in signal may lead to False recognition of Start and Stop bits.
• Response time cannot be predicted.
• Handling of errors are more intricate.
• Applications are comparatively hard to design for such transmissions.

What do you need to know about Frame Relay?

Frame relay is a Packet-Switching Telecommunication Service designed for Cost-Efficient Data Transmission for Intermittent Traffic between Endpoints in Local Area Network (LAN) and Wide Area Network (WAN).

What’s the difference between Frame Relay and ATM?

Key Differences Between Frame Relay and ATM. The packet size in the frame relay varies while ATM uses a fixed size packet known as a cell. ATM produces fewer overheads as compared to the frame relay technology. Frame relay is less expensive respective to the ATM. ATM is faster than the frame relay.

How is Frame Relay used in data link layer?

Frame relay is used to transfer the data in the form of packets, with the help of the data link layer. Here, a unique identifier DLCI (Data link connection identifier) identifies the virtual connection which is referred to as ports. The frame relay basically connects two DTE devices by using a DCE device.

How does Frame Relay work for DTES and DCEs?

Frame relay establishes connection between DTE and DCE using two modes. The figure-1 depicts frame relay network which consists of Frame relay switches between DTEs and DCEs. Each connection is identified using unique DLCI (Data Link Connection Identifier) in frame relay which is carried in frame relay frame.
