Final Exam is Monday, May 5, 12:40-2:40

Here is a summary of the sections that may be covered on the final:

Chapter 7:
7.1:    stop-and-wait and sliding windows intro
7.2:    error detection, especially CRC
7.3:    fine-tuning of sliding windows: go-back-N and selective-reject
7.4:    basics of HDLC, a typical link-level sliding-windows protocol.
        HDLC uses sliding windows on a link-level basis
7.5:    survey of other protocols (ATM, frame relay)

Chapter 8:
8.1:    FDM (traditional)
8.2:    TDM, revisited. Lots on SONET.

Chapter 10:
10.3:   x.25 again (at least as it compares to ATM)

Chapter 11:
11.2:   ATM connections & paths
11.3:   ATM cell format
11.4:   ATM over SONET, etc
11.5:   ATM service categories: CBR, VBR-rt, VBR-nrt, ABR, UBR
11.6:   ATM Adaptation Layer
11.7:   Frame Relay: sort of a "fixed" x.25

Chapter 12:
12.1:   Congestion basics
12.2:   Summary of congestion options
12.3:   More congestion appreaches
12.4:   Congestion summary (very short)
12.5:   ATM traffic management, GCRA, Token Buckets and Leaky Buckets
12.6:   ATM-ABR traffic management


Study questions:

Study the second homework. Here are a few other problems:

1. Using a leaky bucket filter with T=10 and tau=5, initially full,
which of the following packets are conformant? Arrival times are given.

	0	5	10	25	30	40

2. What are some differences and similarities between ATM CBR traffic and
RT-VBR traffic? 


3. What ways can ATM address congestion that are not available in IP?
