Internet Priority Traffic
Note: The ability to give one set of traffic priority over another set of traffic is a significant issue in the Network Neutrality debate.
Internet Emergency Preference Scheme
IEPS webpage: Recommendations E.106 was established by the International Telecommunication Union, Telecommunication Standardization Sector (ITU-T), March 17, 2000. Recommendation E.106 recognizes the requirement for priority communications among governmental, civil, and other essential users of public telecommunication services in crisis situations, such as earthquakes, severe storms, and floods.
IEPS will provide authorized users priority access to telecommunication services and priority processing of communications in support of recovery operations during emergency events.
Work has been initiated in the following industry technology and standards bodies to develop provisions for special handling of priority services to support critical communications in the emerging packet-based network environment:

- ITU-T - International Telecommunication Union - Telecommunication Standardization Sector

Telecommunications Service Priority
The Telecommunications Service Priority (TSP) Program is a Federal Communications Commission (FCC) program used to identify and prioritize telecommunication services that support national security or emergency preparedness (NS/EP) missions. The TSP Program also provides a legal means for the telecommunications industry to provide preferential treatment to services enrolled in the program. TSP Website.
"The Government Emergency Telecommunications Service (GETS) is a White House-directed emergency phone service provided by the National Communications System (NCS) in the Information Analysis and Infrastructure Protection Division of the Department of Homeland Security. GETS supports federal, state, local, and tribal government, industry, and non-governmental organization (NGO) personnel in performing their National Security and Emergency Preparedness (NS/EP) missions. GETS provides emergency access and priority processing in the local and long distance segments of the Public Switched Telephone Network (PSTN). It is intended to be used in an emergency or crisis situation when the PSTN is congested and the probability of completing a call over normal or other alternate telecommunication means has significantly decreased. - GETS Program Information "

National Communications System
- Transcontinental Telegraph Line :: priority for government and military traffic
- Post Roads Act :: Priority for government messages
- Western Union :: In exchange for access to railroad ROW, give priority to railroad messages
- International Telegraph Convention :: priority for government and military traffic (European networks were largely government run)
