2. Unifying principles?The text repeatedly emphasizes such principles as multiplexing, flow
control, and error control, and contrasts their application in specific areas of technology. This
enables students to understand how the same protocol design principles are applied at different
levels of the protocol architecture.
3. Standards?A comprehensive discussion of the current status and future direction of related
technology standards helps students understand the central role of standards in network and
4. More than 250 homework problems?Problems ranging in difficulty give students the
