Recently, coflow has been proposed as a new abstraction to capture the communication patterns in a rich set of data parallel applications in data centers. Coflows effectively model the application-level semantics of network resource usage, so high-level optimization goals, such as reducing the transfer latency of applications, can be better achieved by taking coflows as the basic elements in network...
With the rapidly growing of geo-distributed applications in the Internet, there is a huge amount of data generated in geo-distributed datacenters everyday. However, because of region privacy concerns and limitation of inter-DC WAN bandwidth, moving all the geo-distributed data to a single datacenter for centralized processing is not practical. Therefore, we intend to process the data where it generates...
Data Center is now becoming an important facility for many applications (e.g, web search and retail). As TCP can't meet applications' demands for latency and throughput, many tcp-based protocols (e.g, DCTCP, D2TCP, L2DCT) have been proposed. Among them, protocols such as D2TCP incorporate explicit deadline into congestion window adjustment procedure to guarantee flows' latency and protocols such as...
Interdomain Multipath Routing, which enables a source AS to use more than one paths for a destination AS, is a promising technique for achieving high bandwidth, high resiliency and fast reaction to failures. However, previous interdomain multipath routing protocols often produce paths which might share bottlenecks, which makes them vulnerable to failure on bottlenecks and therefore inefficient to...
In the background of digital home application, network congestion control and emotion cognition model on the basis of the intelligent terminals iNet protocol interactive system were studied. Firstly, network congestion model based on hidden Markov model (HMM) were analyzed, the test and simulation on the linkage path were realized. Thus, the network congestion control and the network service quality...
