  2. Live Mode Collaboration and Reach Back Distributed Gateway Site #1 Gateway Controller Gateway Firewall NOCC Firewall Ship Network (ADNS) • Load Balancing • Replication/Synchronization • “Collaboration” Hosting Connected Mode Data Replication/Synchronization Site #2 Mission Essential EMCON Data & Information Site #3 Wired Network (ISNS) DS 2.0 IT 21 Users Gateway Firewall Wired Network (ISNS) Content/ Data Synch. Sensors (ICAS) Live Wireless Firewall(s) Mobile Applications (TBD Pending Testing and Certification) Sync or Wireless Support Provider Content Providers (RRC, CRM, Tech Data, Navy Content) Support Provider DS 2 Infrastructure

  3. iOra EpsilonUpdate/Synchronization Index Changes to Document NEW Data Block Index Index Changes are built from Existing blocks Of data Document Changes are built from an Index, NEW blocks of data and Existing blocks of Data!

  4. 100MB of updated content Copy of 100MB of updated content Copy of 90MB of initial content 1. IDENTIFY CHANGES 10MB of new and modified files or pages 2. EPSILON Identify 256 byte blocks that do not match any other blocks in any file or page 6. DECRYPT & DE-EPSILON FILES/PAGES ON DEMAND 500KB of unique data blocks 3. COMPRESS & ENCRYPT iOra Client publications database iOra Publisher publications database 200KB amendment file 5. DE-COMPRESS AND ADD TO CLIENT DATABASE 4. TRANSMIT AMENDMENT (< 1 min over 56kbs connection} Example of how Epsilon Works 90MB of initial content

Live Mode Reach Back (3) (2) Gateway Controller Gateway Firewall NOCC Firewall Distributed Gateway Ship Network (ADNS) Connected Mode Data Replication/Synchronization (4) (1) Wired Network (ISNS) Amendment Server Distance Support v 2 Data Synch. Gateway Firewall ICAS Workstation • DS2 server pulls the ICAS data from the ICAS work stations once a week • Once a week the ICAS data is transferred from the DS 2 server off ship to an amendment server • The amendment server receives changes from the ship • The Distributed Gateway pulls the changes from the Amendment server • Data pulled by the ISEA Firewall(s) (5) ICAS – ISEA Pull ICAS Data Flow 68Kbytes Transferred ~2-5 Sec. IMRSAT 68Kbyte File 773Kbyte Increase in File Size In 10 days >400Mbyte File Reconstituted >400Mbyte File Real Ship Data Transfer 30 Dec - 8 Jan. 04
