IDENTIFY AND COMPARE ANY 2 WAN PROTOCOLS

Answer 1

Two popular WAN protocols are MPLS (Multiprotocol Label Switching) and Frame Relay.

MPLS is a packet-forwarding technology that uses labels to make data forwarding decisions. It operates at layer 2.5 of the OSI model, sitting between traditional layer 2 (Data Link Layer) and layer 3 (Network Layer). MPLS creates virtual paths across a network, allowing for faster and more efficient routing of data packets. It is often used by service providers to create private networks for their customers.

Frame Relay, on the other hand, is a legacy WAN protocol that operates at the Data Link Layer (layer 2) of the OSI model. It is a connection-oriented protocol that uses virtual circuits to transmit data between locations. Frame Relay is known for its simplicity and efficiency in handling bursty traffic patterns. However, it has largely been replaced by newer technologies such as MPLS due to its limitations in terms of scalability and flexibility.

In terms of comparison, MPLS offers more advanced features and capabilities compared to Frame Relay. MPLS provides better traffic engineering, quality of service (QoS) options, and support for various types of traffic such as voice and video. MPLS is also more scalable and flexible, making it suitable for complex networks with diverse requirements. Frame Relay, on the other hand, is a simpler and more cost-effective solution for basic point-to-point connections. However, it lacks the advanced features and capabilities of MPLS.
