  1. IEPREP (Internet Emergency Preparedness) By: Jeffery Pelletier

  2. Outline • Explanation of IEPREP (Internet Emergency Preparedness) • Some major threats to an network (ie. Examples) • RFC 3487 • RFC 3690 • RFC 3523 • RFC 3689 • RFC 4190 • RFC 4375 • Statistics from 9/11

  3. IEPREP • Created for times of emergency and/or disasters. • Access to any public telecommunications at hand • Conventional phone • Internet Access • PDAs • Cell Phone • IP Telephones • The objectives: • Create Network that will not get over congested in the time of an emergency. • Have uninterrupted communication between emergency personal. • Have proper authorization given to certain individuals.

  4. Potential Threats to a Network • Natural Disasters • Hurricanes • Floods • Tornados • Tsunamis • Fires • Earthquakes • Man-Made Threats • Terrorist Attacks • Plane Crashes • Hackers

  5. RFC 3487 • Session Initiation Protocol (SIP) • In times of emergencies, there needs to be access to circuit switched networks by emergency personal. • SIP contain large handling capabilities • Limited though due to network capacities. • Network Topologies: • IP end-to-end • IP to CSN • Network Models: • Pre-configured for ETS • Can modify behavior of certain protocols • Transparent Model • Transfer valid IP packets but has no control over protocols • SIP/RTP transparent • User is in control of incoming/outgoing calls • Restricted SIP • Cannot add certain SIP protocols

  6. RFC 3690 • IP telephony requirements • Mapping used to distinguish PSTN lines • Regular traffic vs. emergency traffic • Exists in Application layer • To keep track of billing • To keep track of authorized usage. (abuse of service)

  7. RFC 3523 • Describes topology naming conventions for IEPREP phone calls • Four topologies: • IP bridging • IP core between two circuit-switched networks • IP at the start • An IP phone makes a call to a circuit switched phone • IP at the end • A circuit switched phone makes a call to an IP phone • End-to-End IP • There are no circuit switched network phones and IP phones are used at both ends

  8. RFC 3689 • Emergency Telecommunications System (ETS) • Network setup for use in the times of emergencies • Explains labeling • Numeric • Alphanumeric • String of bits Emergency Standards • T1.631 = Used in accordance with the GETS system. • E.106 = Guide to PSTN phone lines in the times of an emergency. • F.706 = Extends E.106 into Multimedia type applications. • H.604.4 and I.255.3 = Multi-level label mechanism for emergency communications. • Four Requirements • IF Signaling = Fact that there is an emergency present. • Labels = Method to determine content of traffic. • Policy = Determines explanation of a specific characteristic. • Network Functionality = Probabilities vs. Guarantees.

  9. RFC 4190 • Emergency system other than the norm • 911 system in US • 999 system in England • Need for a system that extends national boundaries. • Governmental Emergency Telecommunications Systems (GETS) • United States Emergency System • First overseen by National Communication System • Post 9/11, now overseen by newly formed Department of Homeland Security. • Given priority over regular phone traffic. • Credit card like approach used for authorization. • Service guarantee (certain amount of packets get through no-matter what) • Agencies Included in GETS development and advancement: • Federal Emergency Agency (FEMA) • NASA • Department of Transportation

  10. RFC 4375 • ETS • Single administrative Domain • 4 examples • Resource Domain = Router or a host and the physical media used connect the two. • Administrative Domain = Collection of resources under one single authority. • Transmit Domain = Transmits data from one domain to another. • Stub Domain = Administrative domain that deals with the source of destination of an IP packet.

  11. Statistics from 9/11 • AT&T had call numbers of 430 million • Up from 100 million from the previous day. • Verizon Wireless had a 100 percent call increase from the previous day. • Increase of 100 percent of Washington DC phone usage. • Increase of 1000 percent of New Jersey phone usage.
