Description
If MLPP attributes are not associated with the information being transmitted between systems, then access control policies and information flows which depend on these MLPP attributes will not function and unauthorized access may result. Without the implementation of safeguards which allocate network communication resources based on priority, network availability, and particularly high priority traffic, may be dropped or delayed. DoD relies on the implementation of MLPP to ensure that flag officers and senior staff are provided higher priority for communications than other users. For VoIP and videoconferencing systems, Voice Video Session Managers must communicate using protocols and services that provide expedited packets to users and other systems.
