文档介绍：works: A Systems Approach Fourth Edition Solutions Manual Larry Peterson and Bruce Davie 2007 1 Dear Instructor: ThisInstructors’ Manualcontains solutions to most of the exercises in the fourth edi- tion of Peterson and Davie’works: A Systems Approach. Exercises are sorted (roughly) by section, not dif?culty. While some exercises are more dif?cult than others, none are intended to be ?endishlytricky. A few exercises (notably, though not exclusively, the ones that involve calculating simple probabilities) require a modest amount of mathematical background; most donot. There is a sidebar summarizing much of the applicable basic probability theory in Chapter 2. An occasional exercise is awkwardly or ambiguously worded in the text. This manual sometimes suggests better versions; also see the errata at the web site. Where appropriate, relevant supplemental ?les for these solutions () have been placed on the textbook web site,e. Useful other material can also be found there, such as errata, sample programming assignments, PowerPoint lecture slides, and EPS ?gures. If you have any questions about these support materials, please contact your Mor- gan Kaufmann sales representative.

An alternative interpretation would be to count until the last ACKarrives back at the sender, in which case the time would be half an RTT (50ms)
