  2. What is ADNS? • ADNS is an integral part of a complex communications system that provides an automated pathway for information to travel along any available transit link. • Provides for optimal use of bandwidth assigned by the system to: • UNCLAS • SECRET • SCI • Coalition • Other afloat networks and their shore counterparts

  3. ADNS “Vision” • Provide assured gateway availability for critical paths/applications • Guarantee 100% end-to-end delivery of selected voice, video, and data • Provide restore capabilities • Increase information transfer efficiency • Reduce manning and operation costs • Provide joint interoperability

  11. ADNS Increment I • Constraints • IP traffic uses only one RF link even if more are connected • Best Effort delivery (i.e. no application has priority) • Fixed bandwidth allocation to each enclave Capabilities • Consolidated WAN access for Multi-security level networks (via NES, TACLANE) • Link preference: DSCS, CWSP, EHF, IMS • Hot-standby Link Failover • Bandwidth Reservation per security level • Ship-to-Ship LOS links w/IP (VTC over DWTS) • Ship-to-Shore MAGTF support • Pier-side network access

  12. Justification for Change • Increased demand requires more efficient use of RF bandwidth • Need to prioritize network traffic • Must be able to monitor and control network traffic based on applications

  13. Inc II Capabilities • Increment II = Inc I plus: • Traffic distribution over multiple links • Adjustable bandwidth guarantees • Application prioritization • Improved link monitoring tools • Application monitoring

  14. Components • Integrated Network Management (INM) • LQoSMAN • Routing and Switching • Cisco router • Packetshaper • TACLANE

  15. Software • Windows 2003 Server + patches • Internet Explorer (IE) + patches • Apache Web Server • Adobe Acrobat Reader WinZip • mIRC Chat Client (and patches) • Tera Term Pro • Norton Antivirus • IT-20 Security scripts • Cisco IOS • PacketWise • PacketShaper Tool

  16. 32 bit, secure, Network Operating System that controls system hardware and provides a platform for running applications. Monitors ADNS software and controls ADNS devices. • Industry standard for large networks. • IAVA’s and FAMs are issued with directions to download and perform updates and patches.

  17. Apache Web Server • Provides support for storing, managing, and displaying of HTML based content to local and network users. • Enables network users to access the local ADNS INM functionality using the IE browser. • Monitor network connectivity • Configure information display • Configure and generate reports • Configure QoS and bandwidth management settings

  18. mIRC • mIRC is an Internet Relay Chat (IRC) program that connects to a host chat server at NCTAMS PAC and LANT. • Chat room to allow users to communicate with each other for testing and troubleshooting.

  19. LQoSMAN 3.x Software Tool Kit • Standalone IBM compatible workstation running Windows Server software • Provides status information • Monitors via Ethernet link • Uses SNMP • Provides remote access and monitoring via SIPRNET web access.

  20. User Levels • Administrator (Monitor/Manage) • Access all software modules and monitoring • Manage the entire ADNS • Operator (Monitor) • Monitor performance • Generate reports • Change screen preferences • Read-Only • Web access to view how ADNS is working

  21. Policy-Based Routing (PBR) • Source-Based Transit Provider Selection • Quality of Service (QOS) • Cost Savings • Load Sharing

  22. Quality of Service (QoS) • Control over resources • More efficient use of network resources. • Tailored Services • Grades of service differentiation to the customers. • Coexistence of mission-critical applications • Bandwidth and minimum delays required by time-sensitive multimedia and voice applications are available, and that other applications using the link get their fair service without interfering with mission-critical traffic. • Foundation for a fully integrated network in the future

  23. Inc 2 Enhancement # 1 • Traffic Distribution • Benefits • Using multiple links increases effective bandwidth • Improves overall system reliability

  24. Traffic Distribution for Force Level Platforms

  25. Inc 2 Enhancement # 2 • Selectable Enclave Bandwidth Allocation • Baseline Configuration • SIPR-Favored • SCI-Favored

  26. Percent Bandwidth Allocation (Force Level)

  27. Inc 2 Enhancement # 3 • Application Prioritization • Based on source application • Packets dropped depends on: • Degree of congestion • Priority of packets • ADNS Inc II uses PacketShaper (Packeteer)

  28. Unclassified Application Priorities

  29. Inc 2 Enhancement #4 • Application Monitoring and Blocking • PacketShaper Overview • Traffic and Bandwidth Management system that delivers predictable efficient performance for applications running over the WAN • 7 Layer classification, analysis, control, and reporting capabilities. • Enables managers to keep critical traffic moving at an acceptable pace through bottlenecks and prevents any single type of traffic from monopolizing the link.

  30. The Bottleneck High-Speed DISA/HSGR Backbone 64 kbps – 1.5 Mbps OC-3, OC-12, OC-48, OC-192 10/100/1000 Mbps Problem: Traffic on the high-speed LAN hits the low-speed WAN access link before getting to the really high-speed shore infrastructure.
