BCube: a high performance, server-centric network architecture for modular data centers
TLDR
Experiments in the testbed demonstrate that BCube is fault tolerant and load balancing and it significantly accelerates representative bandwidth-intensive applications.
Rapier: Integrating routing and scheduling for coflow-aware data center networks
TLDR
This work presents Rapier, a coflow-aware network optimization framework that seamlessly integrates routing and scheduling for better application performance, and demonstrates that Rapier significantly reduces the average coflow completion time.
FiConn: Using Backup Port for Server Interconnection in Data Centers
TLDR
The new network design, called FiConn, utilizes both ports and only the low-end commodity switches to form a scalable and highly effective structure, and it is proven that FiConn is highly scalable to encompass hundreds of thousands of servers with low diameter and high bisection width.
MDCube: a high performance network structure for modular data center interconnection
TLDR
MDCube, a high performance interconnection structure to scale BCube-based containers to mega-data centers, uses the high-speed uplink interfaces of the commodity switches in BCube containers to build the inter-container structure, reducing the cabling complexity greatly.
ESM: Efficient and Scalable Data Center Multicast Routing
TLDR
Simulations show that ESM saves 40% ~ 50% network traffic and doubles the application throughputs compared to receiver-driven multicast routing, and the combination routing scheme significantly reduces the number of in-switch entries required.
Scalable and Cost-Effective Interconnection of Data-Center Servers Using Dual Server Ports
TLDR
It is proven that FiConn is highly scalable to encompass hundreds of thousands of servers with low diameter and high bisection width, and developed a low-overhead traffic-aware routing mechanism to improve effective link utilization based on dynamic traffic state.
IP-Geolocation Mapping for Moderately Connected Internet Regions
TLDR
This paper develops a simple and novel IP-geolocation mapping scheme for moderately connected Internet regions, called GeoGet, which outperforms current schemes such as GeoLim and GeoPing, and discovers a more probable rule - with high probability the shortest delay comes from the closest distance.
Reliable Multicast in Data Center Networks
TLDR
The experiments show that RDCM handles packet loss without obvious throughput degradation during high-speed data transmission, gracefully respond to link failure and receiver failure, and causes less than 10% CPU overhead to data center servers.
PACE: Policy-Aware Application Cloud Embedding
TLDR
PACE is presented: the first systematic framework for Policy-Aware Application Cloud Embedding, which precisely defines the policy-aware, cloud application embedding problem, study its complexity and introduces simple, efficient, online primal-dual algorithms to embed applications in cloud data centers.
Exploring efficient and scalable multicast routing in future data center networks
TLDR
The technical trend of future data center design poses new challenges for efficient and scalable Multicast routing, which means it is quite difficult for the low-end switches largely used in data centers to hold the routing entries of massive Multicasts groups.
