What does it mean to have "connection status information" while using a virtual circuit network? One connection per millisecond is the rate at which a switch's forwarding database must be updated in a virtual circuit (VC) network (on average).

This layer creates a virtual circuit before data may be sent between two endpoints.

What is the purpose of a Layer 2 switch in the OSI model?

List the characteristics that set synchronous and isochronous connections apart, and provide an example of each.

What is the primary function of a switch in the OSI model, and which layer does it operate on?

What does virtual circuit network connection status information mean? What rate does the forwarding table in the switch need to be adjusted if connections are formed and dropped in a VC network switch at a rate of one connection per millisecond (on average)?

What is meant by the term "software-defined networking" (SDN) controller?

Describe the primary functions of a network switch in the context of the OSI model.

Explain the difference between synchronous and isochronous connections and provide an example of each.

Suppose a workstation has an I/O bus speed of 1 Gbps and memory bandwidth of 2 Gbps. Assuming DMA is used to move data in and out of main memory, how many interfaces to 100-Mbps Ethernet links could a switch based on this workstation handle?
