Is Frame Relay circuit switching or packet switching?
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).
Is Frame Relay circuit switched?
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). Frame relay devices create SVCs when data needs to be transferred and then close those connections when they aren’t in use.
Is Frame Relay A 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.
Is Frame Relay a WAN technology?
Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology.
Are frame relays copper or fiber?
Frame relay operates over fiber-optic or ISDN lines and supports different higher-level network protocols, including internet protocol (IP).
Is Frame Relay still used?
The reason you are learning Frame Relay & PPP is to comprehend basic networking principles. Today, these technologies are no longer widely used (although Cisco sells rather a lot of them to people running obsolete but useful/valuable networks).
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.
What has replaced Frame Relay?
Frame Relay has no quality of service (QoS) manageability and is largely being replaced by the more cost effective MPLS VPN Solutions. Hardware VPNs are commonly configured as a hub and spoke network.

What is replacing Frame Relay?
MPLS VPN Solutions
Frame Relay has no quality of service (QoS) manageability and is largely being replaced by the more cost effective MPLS VPN Solutions. Frame Relay is commonly configured as a hub and spoke network. Frame Relay can run over MPLS to obtain the benefits of traffic prioritization and management.
Which is better Frame Relay or ATM?
5 Mbps or 622 Mbps. ATM provides error management and flow management. it’s a decent reliable than frame relay….Asynchronous Transmission Mode (ATM):
| S.NO | Frame Relay | ATM |
|---|---|---|
| 7. | Frame relay does not provide error control and flow control. | While ATM provides error control and flow control. |
What is frame relay in CCNA?
In frame relay, the routers connected to remote networks are usually the DTE devices while the frame relay switch is usually the DCE device. The frame relay switches move data frames from the host networks across the WAN network to the remote DTE devices.
