What type of connection might a frame-relay use?

What type of connection might a frame-relay use?

Rather than using a full-time leased line between remote sites, frame-relay devices create one of two types of connections: Switched virtual circuits (SVC) or permanent virtual connection (PVC).

What is a frame-relay connection?

Frame relay is a packet-switching telecommunications service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between endpoints in wide area networks (WANs). The service was once widely available and implemented.

How does frame-relay operate?

Frame Relay sends information in packets called frames through a shared Frame Relay network. Each frame contains all the information necessary to route it to the correct destination. So in effect, each endpoint can communicate with many destinations over one access link to the network.

Which two devices are used on frame-relay connection?

The technology has become a stand-alone and cost-effective means of creating a WAN. Frame Relay switches create virtual circuits to connect remote LANs to a WAN. The Frame Relay network exists between a LAN border device, usually a router, and the carrier switch.

Who is the largest frame relay provider in the US?

AT was by far the largest Frame Relay provider, with an installed base estimated at $6 billion annually.

Is Frame Relay on CCNA?

Frame-relay is one of the WAN protocols you need to understand if you plan to become CCNA certified. It’s also one of the most difficult protocols to understand for most CCNA students.

Who is the largest Frame Relay provider in the US?

Is Frame Relay is a network protocol?

Frame relay is a protocol that defines how frames are routed through a fast-packet network based on the address field in the frame. Frame relay takes advantage of the reliability of data communications networks to minimize the error checking done by the network nodes.

Why do we use Frame Relay?

How does Frame Relay compare to sending data over the Internet?

How does frame relay compare to sending data over the Internet? Frame relay is more secure, faster, but costs more. 25. ATM can support a wide range of traffic types, such as video, music, high and low-speed data, voice, and more.

Which network is cheaper than Frame Relay?

Explanation: Frame Relays uses carriers such as SONET (for fiber-optic connections) to physically transmit data frames over a Frame Relay network. SONET is cheaper and provides better network reliability than other carriers.

How can Frame Relay networks be created give a detailed note?

Frame Relay uses virtual circuits to connect a single router to multiple remote sites. In most cases, permanent virtual circuits are used, i.e. a fixed network-assigned circuit is used through which the user sees a continuous uninterrupted line. However, switched virtual circuits may also be used.

How does Frame Relay work in a network?

Frame Relay is an example of a packet-switched technology. Packet-switched networks enable end stations to dynamically share the network medium and the available bandwidth. The following two techniques are used in packet-switching technology: Variable-length packets are used for more efficient and flexible data transfers.

What’s the difference between Frame Relay and ATM?

Frame Relay complements and provides a mid-range service between basic rate ISDN, which offers bandwidth at 128 kbit/s, and Asynchronous Transfer Mode (ATM), which operates in somewhat similar fashion to Frame Relay but at speeds from 155.520 Mbit/s to 622.080 Mbit/s.

What’s the maximum transmission speed for Frame Relay?

The CIR, a negotiated level of service you purchase from the carrier, specifies your maximum transmission speed over the frame relay network. Speeds typically range from 56 Kbps to T3 speeds and higher, depending on your requirements.

What is the maximum number of octets for a frame relay?

The standard specifies the maximum information field size (supportable by any network) as at least 262 octets.
