CC*Integration: BRACELET: Robust Cloudlet Infrastructure for Scientific Instruments’ Lifetime Connectivity PI: Klara Nahrstedt University of Illinois at Urbana-Champaign klara@Illinois.edu

Current situation in campus scientific instruments cyber-infrastructure Private Cloud Campus Network Building Building Building Building L2 high speed L2 high L2 high-speed L2 high switch speed switch switch speed switch Older instruments New instruments New instruments (offline)

Goal of BRACELET: Connect older Scientific Instruments to Private Cloud • Allow connections from Windows NT, Windows XP, Windows 2000 PCs to Private Cloud • Allow upload of data from old instruments to the private cloud • Allow some curation functions of data close to older instruments

Challenges • Performance mismatch : Older instruments’ Windows NT or XP runs network protocols at lower bandwidth speeds (10Mbps or 100Mbps) • Obsolete security : Older devices and their OS systems cannot be patched, hence being vulnerable & taken offline

Approach: Putting edge device between older instruments and private cloud Private Cloud Campus Network Building Building L2 high Building Building L2 high-speed L2 high speed switch speed switch L2 high switch speed switch Cloudlet Cloudlet New New L2 slow L2 slow instruments speed switch …. speed switch instruments ….

Approach: Putting edge device between older instruments and private cloud • Performance component : • Have two network interfaces configured at different speeds • Perform traffic shaping from slower to faster network • Security component : • User & instrument registration • Data encryption during upload • Firewall to protect against external threats
