The goal of this session is to characterize the programmable network substrate GENI will provide to network researchers.
Network traffic within a GENI slice is segregated along some fixed dimension (e.g. VLAN ID), providing a sandbox for researcher.
Experimenter may customize network flows or modify frames/packets at provided programmability loci (e.g. OF switches)
NB: whatever dimension is used for slicing the network may not be modified by researcher in programming the network.
The campus may have multiple administrative domains: the data center, plus ‘west campus’ and ‘east campus’, say.
The Regional and Backbone may have nodes at many cities in the region that constitute an SDN-enabled topology. Some nodes may have GENI Racks, others don’t.
It may be that the granularity to view and control network topologies is not the single node, nor the whole network, but, because of administrative domains, somewhere in-between.
The Regional and Backbone present aggregates for each GENI rack plus a single aggregate presenting the topology as a GENI-SDN resource.
The campus presents three aggregates: one for each ‘campus’ plus the data center. Each aggregate presents its computation/storage resources plus its topology as a GENI-SDN resource.
Be inspired but not constrained by how these capabilities have been provided in Meso-scale GENI nor by any plans currently on the drawing board
The goal of this session is to detail the programmable network substrate GENI will provide to network researchers.
