[url] Emulab and Planet Lab

Need to take a look at these two labs. my initial guess, is that they provide an environment for conducting experiments for those people who do not have an active testbed.

1. Emulab:

Netbed, an outgrowth of Emulab, provides integrated access to three disparate experimental environments: simulated, emulated, and wide-area network testbeds. Netbed strives to preserve the control and ease of use of simulation, without sacrificing the realism of emulation and live network experimentation. Netbed unifies all three environments under a common user interface, and integrates the three into a common framework. This framework provides abstractions, services, and namespaces common to all, such as allocation and naming of nodes and links. By mapping the abstractions into domain-specific mechanisms and internal names, Netbed masks much of the heterogeneity of the three approaches. Wide-area resources: Netbed currently includes approximately 32 nodes geographically distributed across approximately 25 sites, largely the machines in the "MIT distributed testbed." Experimenters with a valid research use can get non-root shell access to these shared nodes, with ssh keys and other aspects automatically managed by Netbed. Secure shared filesystem access is coming soon via SFS.

2. Planetlab:

PlanetLab is a global overlay network for developing and accessing new network services. Our goal is to grow to 1000 geographically distributed nodes, connected by a diverse collection of links. Toward this end, we are putting PlanetLab nodes into edge sites, co-location and routing centers, and homes (i.e., at the end of DSL lines and cable modems). PlanetLab is designed to support both short-term experiments and long-running services. Currently running services include network weather maps, network-embedded storage, peer-to-peer networks, and content distribution networks.
