Effective Dual Decomposition Methods in Network Traffic Management with Multipaths

“…log(x s ), that can also represent the resistance of the traffic or find out the fairness of resource allocation. This type of objective is covertly achieved by TCP congestion control today [6] [12]. So, the optimization problem can be written as follows:" maximize ∑ U s (x s ) subject to Rx≤ c, x≥0 (1) "Here both R and x represents variables.…”

“…We also represent available paths by a matrix H where H s lj =1 if path j of source s uses link k and H s lj =0 otherwise. H does not necessarily present all possible paths in the physical topology, but a subset of paths chosen by operator or the routing protocol [6].…”

“…"The researcher has used three major algorithms partial dual, primal dual and full dual for avoiding link loads from link capacity by supplying feedback based on effective capacity instead of actual capacity [3] [6]. In the resulting algorithm, the sources update their path rates based on feedback price just as in In seeing constant step sizes in this section, the t argument is removed from all the step sizes.…”

“…In separate, network operators balance the traffic and minimize a cost function by tuning link weights, where the weight setting problem is truly NP-hard there is no practically optimal solution. [4] [6]. Optimization decomposition, (e.g.…”

“…x+y+z+w≤c, x+y≤ β and z+w≤c-β, new variable β updated by various methods) everyone can be solved locally. The different elements of traffic management were used effectively to analyze and design using scalability theory, which was also used to direct the design of new protocols for congestion control [3], [6], [9 ] and scalability theory was used to evaluate planned traffic engineering guidelines.…”
