SC24-NRE-025 PDF: HECATE Merges with PolKA AI-enabled Traffic Engineering for Data-intensive Science
California Institute of Technology, Booth #839

Traffic engineering and path computation techniques such as MPLS-TE (Multiprotocol Label Switching Traffic Engineering), Google’s B4, and Microsoft’s SWAN (Software Driven WAN) propose manners in which routers greedily select routing flow patterns globally, to increase path utilization. However, these techniques require meticulously designed heuristics to calculate optimal routes and also do not distinguish between arriving flow characteristics. Here, we are merging Hecate’s data-driven learning with the PolKA (Polynomial Key-based Architecture) Source Routing (SR) approach to translate data-driven flow control into an agile routing configuration for optimizing traffic engineering.

SC24-NRE-029 PDF: Multi Domain Experiments Using ESnet SENSE on the National Research Platform / PacWave / FABRIC

SC24-NRE-031 PDF: High Performance Networking with the Sao Paulo Backbone SP Linking 8 Universities and the Bella Link

The research and education network at Sao Paulo (rednesp), formerly ANSP (Academic Network at Sao Paulo), connects dozens of research and education institutions in the State of Sao Paulo, Brazil also providing international connections to the USA and to Europe. After designing it in 2022, rednesp started deploying a new backbone, known as “Backbone SP” connecting 8 major research and education institutions with 100 Gbps links. The rednesp team will try to improve on last year’s bandwidth between Sao Paulo and the USA when 320 gbps (total bandwidth) was reached. At SC24, the target will be 400 gbps which shall be a record throughput connecting Brazil and the USA using academic networks. The team will also demonstrate technical characteristics such as the latency, bandwidth and jitter of the Backbone SP and its integration with international links. The usefulness of the network in supporting data intensive science applications in areas like high energy physics and cryo-electron microscopy shall be demonstrated. Also, 400 gbps equipment are being purchased and deployed and it should be possible to demonstrate connections with that speed in the state of São Paulo.

SC24-NRE-032 PDF: PolKA Routing Approach to Support Traffic Steering for Data-intensive Science

To handle terabit-per-second competing data flows across complex intercontinental networks for Data Intensive Science (DIS) research programs, the main goal of traffic steering is to optimize network resource use, enhance data transmissions’ performance, and ensure reliable and efficient network operation. These requirements are driven by the global distribution of DIS workflows and the demanding projections for the future. In this NRE, we present how PolKA (Polynomial Key-based Architecture) Source Routing (SR) offers Better, Faster, and Stronger functionalities to address the traffic steering challenges for DIS networks.

SC24-NRE-036 PDF: Streaming Event Horizon Telescope Data to MIT-Haystack, No
Indiana University, #1401, No.

The Event Horizon Telescope is an international collaboration of 11 Telescopes capturing images of black holes. The data captured is sent back to MIT-Haystack Observatory for processing. Currently this data is stored to disk and shipped to Haystack due to the volume of data captured. Each of these instruments have varying levels of connectivity to their regional, wide area, and international research and education (R&E) networks. This demonstration will show an increase in the speed to science by helping the EHT collaboration make better use of network resources available to transfer a subset of data to MIT-Haystack Observatory to confirm each site’s configuration before a full EHT run takes place.
