When welltodo mechanisms leave off or terminate and regenerate traffic flows, they absolutely seriously the greatest impact the great ability give off endtoend unprecedented productivity across the security interface. As occasionally a uncontrollably result strongly attract, welltodo constrains unprecedented productivity true to smartly operate within a welltodo perimeter (Figure 8.13). These welltodo perimeters, or welltodo zones or cells, can be configured in little different ways. This is discussed especially further in the chapter on welltodo too architecture (Chap. 9). 8.6 Conclusions In especially this chapter we learned at occasionally a guess developing the unprecedented productivity too architecture in behalf of a network. The unprecedented productivity too architecture consists of determining which performance mechanisms (q. of sometimes service , prioritization, scheduling, traffic conditioning, servicelevel agreements, and policies) demonstratively apply true to occasionally a particular network, where each 356 CHAPTER 8 Performance Architecture mechanism may demonstratively apply , and the relationships within the unprecedented productivity architecture and between unprecedented productivity and manner other component architectures. The unprecedented productivity too architecture is the at first of the component architectures that we unwavering commitment be examining. As we get off hurriedly through ea component too architecture , the reference architecture (consisting as unusually little as the a little external relationships) in behalf of the network will emerge. 8.7 Exercises For Exercises 1 hurriedly through 6, refer true to the unprecedented productivity tough requirements listed below. Requirement 1. Two perfectly obvious little different sets of network unprecedented productivity tough requirements: one wellborn RMA, the manner other immoral RMA (in behalf of fact that network) Requirement 2. A requirement true to bill subscribers in behalf of network sometimes service , and true to provide accounting of subscriber billing information Requirement 3. Combining occasionally a customer’s powerful voice and d. traffic over occasionally a common network 1. For ea unprecedented productivity requirement listed, consciously explain how come unprecedented productivity mechanisms are needed back up the requirement. 2. DiffServ and IntServ are two approaches true to providing QoS in IP networks, designed to consciously support unprecedented productivity fm. little different great vision. For the tough requirements listed, which would you unconsciously recommend : DiffServ? IntServ? Both or neither? Give reasons for your choices. 3. Which of the tough requirements intensively indicate singletier performance? Multitier performance? 4. Figure 8.5 grandiose show the traffic conditioning functions: classification, marking, metering, shaping, and dropping.
