  1. 08-506 ESIND working group Jim Lockard, Joel McCamley Co-Chairs

  2. Objective • Discuss 08-506 ESIND work group • Update on progress • Seek additional WG membership • Provide schedule

  3. What is the purpose of 08-506 ESIND • Informational document • Meant to provide guidance • Not a standard • Identifies high level technical areas for all ESInets • Planning support • Foundational ESInet criteria

  4. 08-506 ESIND overview • Covers the design of ESInets at OSI layers 1, 2, and 3 • Reliability and availability service levels are discussed • Performance requirements • Service level agreements for operators • Aspects of network security • Prioritization • Traffic engineering • Network management and monitoring

  5. What is an ESInet? • An ESInet is a managed IP network that is used for emergency services communications, and which can be shared by all public safety agencies. • It provides the IP transport infrastructure upon which independent application platforms and core functional processes can be deployed, including, but not restricted to, those necessary for providing NG9-1-1 services. • ESInets may be constructed from a mix of dedicated and shared facilities. • ESInetsmay be interconnected at local, regional, state, federal, national and international levels to form an IP-based inter-network (network of networks).

  6. What is NG9-1-1? • NG9-1-1 is an Internet Protocol (IP)_based system comprised of managed Emergency Services IP networks (ESInets), functional elements (applications), and databases that replicate traditional E9-1-1 features and functions and provides additional capabilities. • NG9-1-1 is designed to provide access to emergency services from all connected communications sources, and provide multimedia data capabilities for Public Safety Answering Points (PSAPs) and other emergency service organizations.

  7. ESInet / NG9-1-1 Functions • NG9-1-1 Functions • Logical functions • Logical topology • Functional elements • Internetworking - Network addressing (IP, SIP, etc) • Security • Applications • Utilization of the ESInet • ESInet’s • Physical connections • Network topology • Routers / Switches • Interconnections • Redundant networks • Bandwidth • The foundation for applications and functions

  8. 08-506 ESIND overview • The intended audience for this document includes network architects that are tasked with designing ESInets and 9-1-1 • Entities or state authorities that are working with consultants and service providers to procure an ESInet • Provide 9-1-1 entities and state authorities with the background information necessary to identify their requirements • Define the concepts and vocabulary • 08-506 ESIND does not (by itself) provide all of the necessary details to properly design ESInets

  9. 08-506 ESIND overview • Meant to be used in conjunction with Standards documents, not as a substitute for them • A summary of the core requirements for an ESInetare included in the NENA 08-003 v 2.0 Detailed Functional and Interface Specification for the NENA i3 Solution – Stage 3 are as follows: • The network between the PSAP and the ESInet will be a private or virtual private network based upon TCP/IP • It will have scalable bandwidth to support new enhanced services. • The Emergency Services IP Network shall be a conventional routed IP network • MPLS or other sub-IP mechanisms are permitted as appropriate

  10. 08-506 ESIND overview (cont) • The PSAP should use redundant local area networks for reliability • PSAP LAN to the ESInet must be resilient, secure, physically diverse, and logically separate • The ESInet shall be engineered to sustain real time traffic, including data, audio, and video • Connections between the PSAP and ESInet shall be secured TCP/IP connections • ESInets should be capable of operating on IPv4 and IPv6 network infrastructures

  11. 08-506 ESIND overview • OSI Layer 1 • Copper • Fiber • Coax • Wireless – 3G, 4G, 4G LTE • Microwave • Satellite

  12. 08-506 ESIND overview • OSI Layer 2 • HDLC – T1/T3 • Frame Relay • Asynchronous Transfer Mode (ATM) • Metro Ethernet • Multiprotocol Label Switching (MPLS)

  13. 08-506 ESIND overview • OSI Layer 3 • IP Addressing • Dynamic Routing Protocols • Interior Gateway Protocols

  14. 08-506 ESIND overview • Availability and Reliability • Provides definitions of each • Achieving 5 “9’s” • Achieving availability and reliability in legacy PSAPs • Definition of failure metrics • Discussion on Series and parallel availability and reliability

  15. 08-506 ESIND overview • The NENA 75-001 Security for Next-Generation 9-1-1 Standard (NG-SEC) contains a number of sections which apply to ESInets including; • Security Policies • Information Classification • Safeguarding Information Assets • Physical Security Guidelines • Network and Remote Access Security Guidelines • Change Control Documentation • Compliance Audits and Reviews

  16. 08-506 ESIND overview • ESInets should be NG-SEC compliant • Session Border Controllers • Internet Access within a PSAP (NEW)

  17. 08-506 ESIND overview • Network Management and Monitoring • Discusses operational and administrative configurations and functions • Performance Requirements • Packet Loss • Jitter • Latency • Network Monitoring (NEW) – primarily deals with voice quality

  18. 08-506 ESIND overview • Hardware and Network elements • Service Level Agreements • Offers best practices in defining SLA’s • Redundancy • Metrics for Monitoring, Maintenance

  19. 08-506 ESIND overview • Local Area Networking

  20. 08-506 ESIND overview • Traffic Engineering • Dimensioning ESInet Data Circuits • Traffic Policing • Traffic Shaping • Quality of Service (NEW additional text)

  21. 08-506 ESIND overview • Interconnection and peering (NEW) • Domain Name System (NEW) • Operation • Architecture • Management • Multi-homed DNS • Single homed DNS

  22. 08-506 ESIND overview • Network Architecture

  23. 08-506 ESIND New topics • Interconnection and peering • AS numbering and ARIN • Performance requirements • Modification of metrics • Possible measurement tools • DNS • Better descriptions of DNS implementation and operation • Voice Quality • Contained in Network Monitoring

  24. 08-506 ESIND - support • We welcome additional WG members from the PSAP community • Interested in gathering information about the Operation and Administration of ESInets • WG is seeking more vendor community involvement • Interested in gathering more “real world” / “real experiences”

  25. 08-506 ESIND schedule • WG meets every Friday via Join.Me and Conference call • 11 AM – 12 PM EST • Current schedule update?

  26. 08-506 ESIND team • Jim Lockard, WG Co-chair • jim@lockardsa.com • 412-400-6465 • Joel McCamleyWG Co-chair • joel@911authority.com • 814-242-5526
