1. Assume that your organization has to support the following information flows over the  Wide Area Network:

- 10 standard PCM voice circuits

- 5 data communications streams that are each 64-kbps and are active 20% of the time.

- One 10-Mbps video stream

- E-mail traffic as best effort

a. Given the leasing of a frame relay service, determine the appropriate committed information rate for the service.

b. Given the leasing of an ATM service, allocate the flow among the constant bit rate, variable bit rate and unspecified bit rate services.

2. One of the fundamental characteristics of ATM is the use of fixed size cells for transport.

Discuss the advantages and disadvantages of this approach compared to the  use of variable size frames (as in Ethernet or Frame Relay).
