Which layer is responsible for flow control with sliding windows and reliability with sequence numbers and acknowledgements?
Transport layer
Which layer in the hierarchical Ethernet design model ensures that traffic between local networks will be allowed?
Distribution
Which layer is done by congestion control?
at the network layer, congestion control mechanism takes place
What is the function of ISDN's data link layer?
Ensures that control and signaling information flows properly and is received
What is the advantage of having Layer 2 redundancy built in to a hierarchical network design?
Layer 2 redundancy in a hierarchical network design enhances reliability and availability by providing alternative data paths in case of a failure. This redundancy minimizes downtime and ensures continuous network operation, as traffic can be rerouted through alternate links. It also supports load balancing, improving overall network performance by distributing traffic evenly across multiple paths. Additionally, Layer 2 redundancy allows for easier maintenance and upgrades without disrupting network services.

What are three basic operations of reliability in the transport layer?
tracking transmitted dataacknowledging received dataRetransmitting acknowledge data
What layer is communication reliability on?
Transport (OSI)
WhAT layer support flow control and sequencing?
Flow control and sequencing are primarily supported at the Transport Layer (Layer 4) of the OSI model. Protocols such as Transmission Control Protocol (TCP) implement flow control mechanisms to manage data transmission rates and ensure reliable delivery of packets in the correct order. This ensures that the sender does not overwhelm the receiver and that data is received in the sequence it was sent.
How a data link layer composed and how does it provide its services?
The data link layer is composed of two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The LLC manages communication between the network layer and MAC, providing framing, error detection, and flow control, while the MAC layer controls how data packets are placed on and retrieved from the physical medium. It ensures proper access to the shared medium, manages addressing and encapsulation, and handles collision detection and avoidance in network environments. By performing these functions, the data link layer ensures reliable and efficient data transfer over the physical network.
Which layer osi model is responsible for issuing acknowledgements?
The layer responsible for issuing acknowledgments in the OSI model is the Transport layer, which is the fourth layer. It ensures reliable data transfer through error detection and correction, as well as flow control mechanisms. Protocols like TCP (Transmission Control Protocol) within this layer handle the acknowledgment of received packets to confirm successful delivery.
