Abstract

DETER testbeds [1] are a class of Emulabbased [2] testbed that provide a secure experimental environment through configuration and management. The DETER project [3] at ISI runs a DETER testbed with segments located at USC/ISI and the University of California at Berkeley consisting of more than 250 nodes. In addition to the original Emulab [4], there are several other testbeds based on the same software scattered throughout the US, eg, Wisconsin’s WAIL [5], with different research focus and varying degrees of public access.
Given that each of these testbeds have similar underlying resource and allocation models, but are tuned and managed for specific objectives, it is natural to want to interconnect them. A giv en experiment may need more resources than a single testbed can offer and interconnecting them can provide more. A testbed may contain hardware useful to an experimenter but lack other resources needed for the experiment; connecting two or more testbeds is a natural solution. An experiment may itself naturally combine the environments provided of two or more testbeds. An experiment that consists of a secure set of nodes and a set of nodes outside the secure area may be best implemented as the connection of a DETER secure testbed and another testbed, rather than simulating the two regimes inside one testbed.
