Recent advancement and increased growth in Web technologies have resulted in an even greater need for more efficient scheduling and data transmission strategies. An increased reliance on wireless communications devices, with their constraint issues, has further complicated the problem. While both push and pull strategies provide certain solutions, each has limitations that compromise performance. What is becoming clear is that any optimal solutions will require novel push-pull hybrid approaches. Data Scheduling and Transmission Strategies in Asymmetric Telecommunications Environments helps systems architects and engineers take on this challenge by providing a thorough discussion of major data and scheduling and transmission strategies. Written by two highly respected pioneering researchers, this work takes a comparative and practical approach that incorporates much of the authors' original research. They discuss basic push and pull strategies and examine the challenges posed by customer requests and behavior, before defining ideal hybrid strategies. Exceptionally thorough in this practical approach, they demonstrate the value of separating clients by class and introduce the concept of an importance factor to properly prioritize a system. They also look at a new on-line hybrid solutions for multichannel broadcast problems and go on to address future problems that are likely to remain open. For those seeking to extract the best performance out of data transmission schemes in asymmetric environments, this invaluable resource is unparalleled in its depth of coverage and innovation.
