“…In order to quantify this latency, some experiments were conducted in Emulab [20], where we allocate 11 pc3000 machines (3.0 GHz 64-bit Pentium Xeon with 2GB of RAM and gigabit network cards) and a 100Mbs switched network. The network is emulated as a VLAN configured in a Cisco 4509 switch where we add a non-negligible latency of 10ms in the communications.…”

Abstract. Byzantine Quorum Systems is a replication technique used to ensure availability and consistency of replicates data even in presence of arbitrary faults. This paper presents a Byzantine Quorum Systems protocol that provides atomic semantics despite the existence of Byzantine clients and servers. Moreover, this protocol is integrated with a protocol for proactive recovery of servers. In that way, the system tolerates any number of failures during its lifetime, since no more than f out of n servers fail during a small interval of time between recoveries. All solutions proposed in this paper can be used on asynchronous systems, which requires no time assumptions. The proposed quorum system read and write protocols have been implemented and their efficiency is demonstrated through some experiments carried out in the Emulab platform.

“…To the best of the authors knowledge, the simulation and evaluation in a realworld deployment using the same protocol implementation has not gained much attention yet. Various frameworks exist that combine emulation and simulation [8], [9] (and references therein). Related efforts to automatically generate simulation code from formalized descriptions [10] also exist, but they lack the consideration of a code-transparent execution on a realworld device to ensure comparability of evaluation results.…”

Abstract-Analyzing a communication protocol by means of simulation and real-world experimentation requires careful protocol implementation in both domains. Differences in the implementation may lead to significantly diverging performance results, which may affect the protocol design process adversely. A code-transparent simulation and experimentation framework for Wireless Access Research Platform (WARP) devices is proposed, which is called WARPsim. By extending the simulation engine appropriately, the same application code that runs on WARP devices can be used for simulation. This work studies the implications of this approach using the example of implementing time-critical Medium Access Control Layer (MAC) protocols on WARP devices. In the demonstration, various MAC protocols will be simulated using WARPsim, while changing protocol parameters, but also crucial aspects of the emulated hardware. A graphical representation integrated into the framework allows for an intuitive examination of the protocol behavior.

“…The ExoGENI principles represent a departure in the GENI effort, whose current standards evolved from testbeds that were established and accepted by the research community at the start of the GENI program in 2007: PlanetLab [19], Emulab [23], and ORBIT [20]. Each testbed developed its own control software to manage substrates that are permanently dedicated to that testbed and under the direct control of its central testbed authority.…”

NSF's GENI program seeks to enable experiments that run within virtual network topologies built-toorder from testbed infrastructure offered by multiple providers (domains). GENI is often viewed as a network testbed integration effort, but behind it is an ambitious vision for multi-domain infrastructure-asa-service (IaaS). This paper presents ExoGENI, a new GENI testbed that links GENI to two advances in virtual infrastructure services outside of GENI: open cloud computing (OpenStack) and dynamic circuit fabrics. ExoGENI orchestrates a federation of independent cloud sites and circuit providers through their native IaaS interfaces, and links them to other GENI tools and resources.The ExoGENI deployment consists of cloud site "racks" on host campuses within the US, linked with national research networks and other circuit networks through programmable exchange points. The ExoGENI sites and control software are enabled for software-defined networking using OpenFlow. ExoGENI offers a powerful unified hosting platform for deeply networked, multi-domain, multi-site cloud applications. We intend that ExoGENI will seed a larger, evolving platform linking other third-party cloud sites, transport networks, and other infrastructure services, and that it will enable real-world deployment of innovative distributed services and new visions of a Future Internet.
