{ "item_title" : "Scalable Performance Signalling and Congestion Avoidance", "item_author" : [" Michael Welzl "], "item_description" : "This book answers a question which came about while the author was work- ing on his diploma thesis1]: would it be better to ask for the available band- width instead of probing the network (like TCP does)? The diploma thesis was concerned with long-distance musical interaction (NetMusic). This is a very peculiar application: only a small amount of bandwidth may be necessary, but timely delivery and reduced loss are very important. Back then, these require- ments led to a thorough investigation of existing telecommunication network mechanisms, but a satisfactory answer to the question could not be found. Simply put, the answer is yes - this work describes a mechanism which indeed enables an application to ask for the available bandwidth. This obvi- ously does not only concern online musical collaboration any longer. Among others, the mechanism yields the following advantages over existing alterna- tives: - good throughput while maintaining close to zero loss and a small bottleneck queue length - usefulness for streaming media applications due to a very smooth rate - feasibility for satellite and wireless links - high scalability Additionally, a reusable framework for future applications that need to ask the network for certain performance data was developed.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/46/135/117/1461351170_b.jpg", "price_data" : { "retail_price" : "109.99", "online_price" : "109.99", "our_price" : "109.99", "club_price" : "109.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
