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 ...
Gleaning Network-Wide Congestion Information from Packet Markings
Distributed control protocols routinely have to operate oblivious of dynamic network information for scalability or complexity reasons. However, more informed protocols are likely to make more intelligent decisions. We ...
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 ...
The Preliminary Design and Implementation of the Maestro Network Control Platform
Network operation is inherently complex because it consists of many functions such as routing, firewalling, VPN provisioning, traffic load-balancing, network maintenance, etc. To cope with this, network designers have ...
λ group: Using Optics to Take Group Data Delivery in the Datacenter to the Next Degree
The increasing number of datacenter applications with heavy one-to-many communications has raised the need for an efficient group data delivery solution. This paper presents an unconventional clean-slate architecture called ...
Exploiting Internet Delay Space Properties for Sybil Attack Mitigation
Recent studies have discovered that the Internet delay space has many interesting properties such as triangle inequality violations (TIV), clustering structures, and constrained growth. Understanding these properties has ...
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. ...
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.
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, ...
