User Defined Networks

Within GTS, the researcher is able to describe the logical composition of their desired network.  The user may incorporate general purpose computational servers, advanced OpenFLow switching/forwarding elements, and/or data transport circuits to connect these components. GTS allows the user to specify desired attributes of each resource - such as the geographic location (a city) for a server or switch, or the desired bandwidth capacity of a transport link.

Rapid Prototyping

GTS dynamically allocates and schedules testbeds at the user’s request. From idea to running testbed, a GTS network spanning the entire GEANT footprint can be instantiated in just a few minutes .


Network research must often culminate in studies “at scale” i.e. studying the behavior of a concept as it goes from a small lab experiment to a large globally deployed capability. The base GTS architecture is designed to scale globally – It can support the creation and management of networks containing thousands of network components, spread across a global geographic footprint, and comprised of resource drawn from many different service providers​.

Reduced CapEx, OpEx, administrative overhead, and “ramp up” time

​The design, engineering, contracting, purchasing, deployment, and operation of a “facilities based” network is an enormous effort.  GTS eliminates almost all of these distractions to the actual research. Indeed, with GTS even a small research program can easily be up and running - performing relevant mission oriented research - almost immediately upon award rather than suffering through months of ramp up time and overhead unrelated to the program’s research objectives. 

Security and Privacy ​

Because the GTS testbeds are, by design, insulated and isolated from one another, they are designed to be secure. User access to a project’s testbed(s) is carefully constrained to allow users to see and manipulate only their own testbeds, yet this security is designed to allow authorized users to access their testbed with a minimum of impedance.  ​
