Our take on ANI, OSCARS, perfSONAR, and the state of things to come.
In 2010 ESnet led the technology curve in the testbed by putting together a great multi-layer design, deploying specially tuned 10G IO Testers, became early investors in the Openflow protocol by deploying the NEC switches, and built a research breadboard of end-hosts leveraging open-source virtualization and cloud technologies.
The first phase of the ANI testbed is concluding. After 6+ months of operational life, with exciting research projects like ARCHSTONE, Flowbench, HNTES, climate studies, and more leveraging the facilities, we are preparing to move the testbed to its second phase on the dark fiber ring in Long Island. Our call for proposals that closed October 1st garnered excellent ideas from researchers and was reviewed by the academic and industry stalwarts in the panel. We are tying up loose ends as we light the next phase of testbed research.
This year the OSCARS team has been extremely productive. We added enhancements to create the next version (0.5.3) of currently production OSCARS software, progressed on architecting and developing a highly modular and flexible platform for the next-generation OSCARS (0.6), a PCE-SDK targeted towards network researchers focused on creating complex algorithms for path computation, and developing FENIUS to support the GLIF Automated GOLE demonstrator.
Not only did the ESnet team multitask on various ANI, operational network and OSCARS deliverables, it also spent significant time supporting our R&E partners like Internet2, SURFnet, NORDUnet, RNP and others interested in investigating the capabilities of this open-source software. We also appreciate Internet2’s participation by dedicating testing resources for OSCARS 0.6 starting next year to ensure a thoroughly vetted and stable platform during the April timeframe. This is just one example of the accomplishments possible for the R&E community by commiting to partnership and collaboration.
perfSONAR kept up its rapid pace of feature additions and new releases in joint collaboration with Internet2 and others. In addition to rapid progress in software capabilities, ESnet is aggressively rolling out perfSONAR nodes in its 10G and 1G POPs, creating an infrastructure where the network can be tuned to hum. With multiple thorny network problems now solved, perfSONAR has proven to be great tool delivering value. This year we focused on making perfSONAR easily deployable and adding the operational features to transform it into a production service. An excellent workshop in August succinctly captured the challenges and opportunities to leverage perfSONAR for operational troubleshooting and also by researchers in understanding further how to improve networks. Joint research projects continue to stimulate further development with a focus on solving end-to-end performance issues.
Life in technology tends to be interesting, even though people keep warning about the commoditization of networking gear. The focus area for innovation just shifts, but never goes away. Some areas of interest as we evaluate our longer term objectives next year:
- Enabling the end-to-end world: What new enhancements or innovations are needed to deploy performance measurement, and control techniques to enable a seamless end-to-end application performance?
- Life in a Terabit digital world: What network innovations are needed to fully exploit the requirement for Terabit connectivity between supercomputer centers in the 2015-2018 timeframe?
- Life in a carbon economy: What are the low-hanging fruit for networks to become more energy-efficient and/or enable energy-efficiency in the IT ecosystem they play? Cloud-y or Clear?
