MMS: An Autonomic Network-Layer Foundation for Network Management
Networks cannot be managed without communication among geographically distributed network devices and control agents. Unfortunately, computer networks today lack an autonomic mechanism that enables such communications, and ...
Supplemental Note on Count-to-Infinity Induced Forwarding Loops in Ethernet Networks
In this document, we show that the count to infinity behavior in the RSTP protocol can lead to a temporary forwarding loop in an Ethernet network.
Leaky Buffer: A Novel Abstraction for Relieving Memory Pressure form Cluster Data Processing Frameworks
The shift to the in-memory data processing paradigm has had a major influence on the development of cluster data processing frameworks. Numerous frameworks from the industry, open source community and academia are adopting ...
COMMA: Coordinating the Migration of Multi-tier Applications
Multi-tier applications are widely deployed in today’s virtualized cloud computing environments. At the same time, management operations in these virtualized environments, such as load balancing, hardware maintenance, ...
Analysis of Hadoop’s Performance under Failures
Failures are common in today’s data center environment and can significantly impact the performance of important jobs running on top of large scale computing frameworks. In this paper we analyze Hadoop’s behavior under ...
Maestro: Balancing Fairness, Latency and Throughput in the OpenFlow Control Plane
The fundamental feature of an OpenFlow network is that the controller is responsible for the configuration of switches for every traffic flow. This feature brings programmability and flexibility, but also puts the controller ...
Measurement-Based Analysis, Modeling, and Synthesis of the Internet Delay Space for Large Scale Simulation
The characteristics of packet delays among edge networks in the Internet can have a significant impact on the performance and scalability of global-scale distributed systems. Designers rely on simulation to study design ...
Maestro: A System for Scalable OpenFlow Control
The fundamental feature of an OpenFlow network is that the controller is responsible for the initial establishment of every flow by contacting related switches. Thus the performance of the controller could be a bottleneck. ...
RCMP: A System Enabling Efficient Re-computation Based Failure Resilience for Big Data Analytics
Multi-job I/O-intensive big-data computations can suffer a significant performance hit due to relying on data replication as the main failure resilience strategy. Data replication is inherently an expensive operation for ...
Pacer: Taking the Guesswork Out of Live Migrations in Hybrid Cloud Computing
Hybrid cloud computing, where private and public cloud resources are combined and applications can migrate freely, ushers in unprecedented flexibility for businesses. To unleash the benefits, commercial products already ...
