SplayNet: Distributed User-Space Topology Emulation
| Résumé |
Network emulation allows researchers to test distributed
applications on diverse topologies with fine control over key
properties such as delays, bandwidth, congestion, or packet loss.
Current approaches to network emulation require using dedicated
machines and low-level operating system support. They are generally
limited to one user deploying a single topology on a given set of
nodes, and they require complex management. These constraints
restrict the scope and impair the uptake of network emulation by
designers of distributed applications. We propose a set of novel
techniques for network emulation that operate only in user-space
without specific operating system support. Multiple users can
simultaneously deploy several topologies on shared physical nodes
with minimal setup complexity. A modular network model allows
emulating complex topologies, including congestion at inner routers
and links, without any centralized orchestration nor dedicated
machine. We implement our user-space network emulation mechanisms
in SplayNet, as an extension of an open-source distributed testbed.
Our evaluation with a representative set of applications and
topologies shows that SplayNet provides accuracy comparable to that
of low-level systems based on dedicated machines, while offering
better scalability and ease of use. |
