“…Some of these applications are web search, MapReduce, social network content composition, and advertisement selection. Incast causes the queue buildup and buffer pressure in switches [203]- [205]. According to the reports from large data center operators such as Facebook [200], Google [206], and Microsoft [207], incast problems mostly occur close to the receiver (Top of Rack switches).…”

“…Most of the traffic in wireless cloud networks uses many-to-one communication pattern such as distributed storage systems, data-intensive scalable computing systems and partition/aggregate workflows (Tahiliani et al, 2015). This type of communication with such huge amount of data resulted in TCP incast problem that is widely exist in cloud environments.…”

The promising services offered by cloud computing environments have led to huge amount of data that need to be processed and stored. Wireless cloud networks rely on Transmission Control Protocol/Internet Protocol (TCP/IP) for reliable transfer of data traffic between the cloud end-users and servers and vise-versa. Even though TCP has been successful for several applications, it, however, does not perform well in wireless cloud environments. The many-to-one communication pattern used in such environments with such huge amount of data resulted in TCP incast problem. Transmission Control Protocol incast problem happens in cluster based storage workloads where a lot of end-users communicate simultaneously to a server in the cloud through a bottleneck router, creating buffers overflows which lead to high packet loss. This paper presents an empirical study on TCP incast in current wireless cloud networks and how it is caused. It evaluates TCP-Vegas and TCP-Sack to examine their behaviors and suitability for short-lived connections in terms of queue occupancy level, packet drops, throughput, link utilization and bandwidth unfairness between the TCP connections. It was found that both protocols suffer from high packet loss and link underutilization with comparable throughput.

“…Many online service providers such as Google, Amazon, Microsoft, Facebook and IBM have vastly invested in building data center networks to support large scale computing power and storage. To ensure the integrity of data transmission, the majority of data centers use TCP as its default transport protocol [6] [11]. However, the high-bandwidth and lowlatency environment of data centers is different from the TCP original assumptions [11].…”
