A method and apparatus for providing traffic management for distributed denial of service (DDOS) traffic. Within a communications network, a DDOS detection system monitors network traffic to identify traffic that is designed to attack a particular server within the network and their entry points into the network. A traffic routing control unit is requested to deny service to the DDOS traffic. By selectively manipulating the routing information propagated to network edge routers, the traffic that is denied service is limited to mostly DDOS traffic and is routed to a cleaning center or a null address in the most effective fashion.

A method of and computer software for minimizing aircraft deviations needed to comply with an en route miles-in-trail spacing requirement imposed during air traffic control operations via establishing a spacing reference geometry, predicting spatial locations of a plurality of aircraft at a predicted time of intersection of a path of a first of said plurality of aircraft with the spacing reference geometry, and determining spacing of each of the plurality of aircraft based on the predicted spatial locations.

A system is provided for managing the inbound flow of aircraft to an airfield by ensuring that aircraft are sequenced before departure into an arrival stream. Sequencing uses operational data obtained from airlines and then provides a methodology for sharing this data with the air traffic control (ATC) agency. The outcome is a daily arrival schedule providing a predetermined operational arrival time for each aircraft movement. The operational data used by the system relates to airline punctuality, taxi times at departure airfields and actual flight times predicted on a flight-by-flight basis by airline flight planning systems. This information is combined to effect a predictive arrival time at a desired navigational fix.

A system and method for automating Air Traffic Control operations at or near an airport. as a complete standalone automated system replacing the need for a human controller to make aircraft movement decisions nor the need communicate with pilots, or as semi-automated, where a controller controls how the system operates. The system with related methods and computer hardware and computer software package, automatically manages manned aircraft, remote controlled UAV and airborne-able vehicles traffic at or near an airport, eliminates ATC-induced and reduce pilot-induced runway incursions and excursions, processes control messages related to aircraft or Pilots, communicates with Pilot over ATC radio frequency, receives aircraft positions, communicates control messages with the aircraft avionics, provides pilots a dynamic map with continuous display of nearby traffic operations, shows clearance and information related to runway operations, warns pilot of runway conditions and turbulence from other operations, warns when landing gear is not locked, displays the pilot emergency exits during takeoff roll, shows the pilot when and where to exit from the runway, shows the pilot where and when to cross a junction, calculates and displays pilot optimal speed and timing on taxiways and junctions for saving fuel, calculates congestions, calculates best taxiway routes, calculates when aircraft can cross a runway, provides directives and information to pilot over CPDLC display or dynamic map for airside operations, alerts and triggers breaks of the aircraft on wrong path or when hold-short bar is breached, displays emergency personnel with routing map and final aircraft resting position for emergency operations, takes over an aircraft operation when aircraft is hijacked or deviates from the flight plan, provide standalone or manned Remote Tower functionality, Records and retains all information related to airport airside operations including aircraft positions and conditions from sensors and reports for runways, junctions and taxiways, Records and retains aircraft data and cockpit voice to ground-based servers to eliminate black-box requirements, calculate future weather and airport capacity from aircraft at or nearby airport, coordinates handoff operations with other ATC positions, interfaces with ACDM systems, airport operations center, flow center and network operations center.

A method for predicting the trajectory of an aircraft is disclosed. It yields the arrival / departure times for a plurality of aircraft with respect to a specified system resource and is based upon specified data and other operational factors pertaining to the aircraft and system resource. This process comprises the steps of: (a) collecting and storing the specified data and operational factors, (b) processing, at an initial instant, the specified data that is applicable at that instant to the aircraft so as to predict an initial trajectory encompassing arrival / departure times for each aircraft, (c) upgrading these initial trajectory predictions for effects of: (1) environmental factors (weather, turbulence), (2) actions of the Air traffic Control system (e.g., stacking incoming aircraft when runway demand is greater than availability), and (3) secondary assets (e.g., crew availability / legality, gate availability, maintenance requirements), (d) communicating these trajectory predictions to interested parties and (e) continuously monitoring all trajectories, and, as necessary, updating the predictions.

A communication system includes overload control at a platform level. A translator module receives messages from any number of distinct networks and provides priority information regarding each of those messages to an overload control module that uses the translated priority information and arrival rate information to provide needed message traffic control. The disclosed arrangement provides a universally applicable overload control approach that reduces duplicated resources associated with individual overload control algorithms for each network message processor.

A method for controlling traffic flow at a network node including updating a plurality of credit buckets over multiple time intervals and determining an adjusted credit value for a credit bucket when the credit bucket is accessed to forward a packet, the adjusted credit value being determined as a function of a number of the time intervals that have elapsed since the credit bucket was last updated, the credit bucket being one of the plurality of credit buckets.

A weather monitoring and prediction system that uses a fleet of aircraft to obtain data. Each aircraft has a local air data system that facilitates the measurement, recordation, and transmittal of local atmospheric data such as barometric pressure, and the corresponding temporal, positional, and altitudinal data. The data is electronically transmitted from each aircraft to a ground based processing system where it is stored. The data may then be transmitted to subscribing users such as aircraft, other weather data systems or to air traffic control centers in either a compiled form or in a raw form. Another embodiment also provides for measuring barometric pressure as a function of altitude at an in-flight aircraft.

The invention provides a four-dimensional flight track dynamic prediction method based on ADS-B information updating. By communicating with networks among ADS-B receivers, a ADS-B data decoding module is adopted to obtain real-time velocity information, height information, longitude information and latitude information of a flight, and consistency check is conducted on a predicted flight track and the real-time velocity, height, longitude and latitude of the flight, so that the dynamic, online and real-time flight track prediction capability is achieved. The method can provide important technical support for developing the automation and intellectualization of air traffic control and achieving the flight-track-based operation.
