and the E bit set to 0, while the last segment shall have the B bit set to 0 and the E bit set to 1. All segments in between shall have both the E and B bits set to 0. The U bit indicates that this chunk belongs to an unordered data stream. In other words, the order of user messages in the stream is not significant and the value of the stream sequence number should be ignored. In such a case, SCTP passes the data to the appropriate upper layer without any concern for the order of the message. SCTP must still, however, ensure that segmented messages are reassembled before passing the data to the upper layer. The transmission sequence number (TSN) is a 32-bit integer identifying this chunk in the context of the association. It is independent of any stream sequence number and is assigned by SCTP rather than by any user of SCTP. When an endpoint sends an INIT chunk, it includes a TSN value, which corresponds to the first DATA chunk that it plans to send. Thus, the first DATA chunk sent will contain the same value of TSN as in the INIT chunk. Thereafter, the TSN is incremented for each new DATA chunk that the endpoint sends in this association. The stream identifier (S) is a 16-bit integer, identifying the stream to which the data belongs. The stream sequence number (n) is a 16-bit integer indicating the position of this message within the stream. For a given stream, the value of the stream sequence number begins at 0. It is incremented for each message sent in a given stream. Note that a segmented message shall have the same value of the stream sequence number in each segment. The payload protocol identifier is passed from the user to SCTP at the sending end and passed from SCTP to the destination user at the receiving

Measurements of traffic distribution by node, by connection, or by protocol can be used to determine which users and which applications are consuming network bandwidth. Understanding how network bandwidth is being consumed allows for intelligent allocation of precious bandwidth in situations where traffic congestion might otherwise limit network performance. Traffic distribution measurements are made both by frame counts and by byte counts, expressed either as an average rate per second over each measurement time interval, or as a cumulative total since the beginning of the measurement period. Frame rate totals are valuable for evaluating forwarding device overload (in bridges, routers, etc.), while byte rate is more useful when dealing with congestion of the transmission media. Node statistics are counts of frames and bytes transmitted and received by each node or station active on the network over the measurement time interval. Monitoring traffic by node is useful in determining which nodes are responsible for generating or receiving the most data. When node statistics are reported in order of frames or bytes transmitted, it is referred to as a top talkers measurement. Connection statistics keep track of the number of frames and bytes sent and received between each pair of stations communicating over the network over the measurement time interval. Connection statistics can be tracked at different protocol levels, including MAC-level connections (by Data Link layer or MAC address) and Network-level connections (by network address, such as IP or IPX). Protocol statistics measure data traffic by protocol type. Each frame is counted according to the protocol type of the information it is carrying, as determined by the protocol type field that is present in the frame. These statistics track data traffic both by frames and by bytes. Protocol statistics can be measured and reported at various levels within the different protocol layers. At the MAC level, i.e., a network protocol being carried in the

Highway Bill signed by President Eisenhower in 1956, authorizing a 42,500-mile superhighway system. Public transportation and the railroads the big losers in Japan and Europe due to World War II damage also became the big losers in the United States as the U.S. government formally finished the job that major industrial corporations, acting in conspiratorial secrecy and convicted of violating the Sherman Antitrust Act, had started in the 1930s and 1940s: ripping up the tracks, dismantling the infrastructure, and scrapping intercity and intracity light rail and trolley systems that could have saved consumers, cities, and the environment the expenditure of billions of dollars today. (Source: Jonathan Kwitny, The Great Transportation Conspiracy, Harper s, February 1981.) The post World War II rebuilding of European and Japanese infrastructures made them more modern than the United States. Germany and Japan (and most of the rest of the industrialized world) rapidly converted from coal to oil economies after World War II, and underwent an unprecedented period of economic and industrial expansion as the surge in automobile registrations outside of the United States, shown in Figure 3-6, attests. All the industrialized economies of the world were now dependent on internal combustion engine vehicles and oil. While electric vehicle automobile development languished since the 1920s (except for Detroit Electric s efforts), commercial and industrial EV activities continued to flourish, perhaps best exemplified by Great Britain s electric milk trucks (called floats ) and its total electric vehicle population of more than 100,000. The heightened environmental concerns of the 1960s, specifically air pollution, were the first wave upon which electric vehicles rose again. While numerous 1960s visionaries were correctly touting EVs as a solution, the manufacturing technology was, unfortunately, not up to the vision. Figure 3-7 shows a chronological summary of what was being done by the primary electric vehicle developers in the United States, Europe, and Japan during the four waves.
