Towards predictable datacenter networks
TLDR
The case for extending the tenant-provider interface to explicitly account for the network is made, and the design of virtual network abstractions that capture the trade-off between the performance guarantees offered to tenants, their costs and the provider revenue are proposed. Expand
Towards predictable datacenter networks
The shared nature of the network in today's multi-tenant datacenters implies that network performance for tenants can vary significantly. This applies to both production datacenters and cloudExpand
Better never than late: meeting deadlines in datacenter networks
TLDR
Evaluation from a 19-node, two-tier datacenter testbed shows that D3, even without any deadline information, easily outperforms TCP in terms of short flow latency and burst tolerance, and effectively doubles the peak load that thedatacenter network can support. Expand
Decentralized Task-Aware Scheduling for Data Center Networks
Many data center applications perform rich and complex tasks (e.g., executing a search query or generating a user’s news-feed). From a network perspective, these tasks typically comprise multipleExpand
Better never than late: meeting deadlines in datacenter networks
The soft real-time nature of large scale web applications in today's datacenters, combined with their distributed workflow, leads to deadlines being associated with the datacenter applicationExpand
Silo: Predictable Message Latency in the Cloud
TLDR
This work presents Silo, a system that offers guaranteed network bandwidth, guaranteed packet delay and guaranteed burst allowance in multi-tenant datacenters and demonstrates that it can ensure predictable message latency for cloud applications while imposing low overhead. Expand
Towards a global IP anycast service
TLDR
The paper presents a detailed design of PIAS and evaluates its scalability and efficiency through simulation, and presents preliminary measurement results on anycasted DNS root servers that suggest that IP anycast provides good affinity. Expand
A study of prefix hijacking and interception in the internet
TLDR
The authors' hijacking estimates are in line with the impact of past hijacking incidents and show that ASes higher up in the routing hierarchy can hijack a significant amount of traffic to any prefix, including popular prefixes. Expand
Bridging the tenant-provider gap in cloud services
TLDR
This work argues for a "job-centric" cloud whereby tenants only specify high-level goals regarding their jobs and applications, and presents Bazaar, a cloud framework offering a job-centric interface for data analytics applications that enables a symbiotic tenant-provider relationship. Expand
IOFlow: a software-defined storage architecture
TLDR
IOFlow is an architecture that uses a logically centralized control plane to enable high-level flow policies and adds a queuing abstraction at data-plane stages and exposes this to the controller to translate policies into queuing rules at individual stages. Expand
