  1. Integrating BEN to ORCA Ilia Baldine Renaissance Computing Institute ibaldin@renci.org

  2. BEN Overview • Metro-scale dark-fiber facility • 4 PoPs on campuses (UNC-CH, Duke, NCSU) and RENCI • Power/space/cooling at each PoP (3 racks) • Out-of-band management network • Remote power management

  3. BEN Overview

  4. BEN Substrate • Each PoP is equipped with • Polatis fiber switch • Infinera DTN (DWDM) • Cisco 6509 • Blades for VM instatiation

  5. Lease State Machine Broker policy selects resource types and sites, and sizes unit quantities. original lease term Broker Ticketed Extending Guest may continue to extend lease by mutual agreement. request ticket extend update ticket request ticket return ticket Reservation may change size (“flex”) on extend. Resources join guest application. Service Manager Active Ticketed Extending Active Closed Nascent Joining Ticketed Active Guest uses resources. form resource request request lease extend return lease update lease redeem ticket close handshake Site Authority Priming Extending Active Time Teardown/reclaim resources after lease expires, or on guest-initiated close. Site policy assigns concrete resources to match ticket. Initialize resources when lease begins (e.g., install nodes).

  9. BEN Slicing Future steps • Add drivers for • Polatis fiber switches • DTN platforms • GMPLS (need to peek at TED) • Explicit setup • Use NDL for substrate description and slice specification • Replace ORCA resource model with ontology-based one • Add cross-layer path validation and then computation • VM substrate • Eucalyptus/EC2 • VMWare
