Alibaba runs the largest e-commerce platform in world serving more than 600 million customers, with a GMV (gross merchandise value) exceeding USD 768 billion FY2018. Online transactions have three notable characteristics: (1) drastic increase of per second kickoff major sales and promotion events, (2) large number hot records that can easily overwhelm system buffers, (3) quick shift "temperature'' (hot v.s. warm cold) different due to availability promotions on categories over short time...

Information centric networks (ICNs) allow content objects to be cached within the network, so as provide efficient data delivery. Existing works on in-network caches mainly focus minimizing redundancy of improve cache hit ratio, which may not lead significant bandwidth saving. On other hand, it could result in too frequent caching operations, i.e., placement and replacement, causing more power consumption at nodes, shall avoided energy-limited delivery environments, e.g., wireless networks....

In Software Defined Networks (SDN), more packet fields are included to design fine-grained policies. These policies stored as entries in switch Flow Table. However, cause the scalability issue a single flow entry needs larger storage space and significant number of need be stored, but Table is limited due constraints Ternary Content Addressable Memory (TCAM). To address this issue, we propose Adaptive Hard Timeout Method (AHTM) improve utilization by optimizing timeouts entries, thus reused...

In this paper, we study the tradeoff between two important traffic engineering objectives: load balance and energy efficiency. Although traditional commonly used multi-objective optimization methods can yield a Pareto efficient solution, they need to construct an aggregate objective function (AOF) or model one of objectives as constraint in problem formulation. As result, it is difficult achieve fair these objectives. Accordingly, induce Nash bargaining framework which treats virtual players...

In Software Defined Networks (SDN), applications on the controller could enforce fine-grained control flows by policies employing more packet fields. These are converted to flow entries and stored in switch Flow Table. To store these entries, Table requires large storage space because an entry consisted of fields needs number also increases significantly due fine-granularity definition flows. However, has limited owing constraints Ternary Content Addressable Memory (TCAM). As a result, SDN...
