1. A network gateway for time-critical and mission-critical networks, comprising:
- a decision unit for transparently intercepting frames flowing between a ground network and an aerial network, wherein the frames are intercepted at a data link layer, the decision unit is further configured to determine based on at least one network event, if each frame of intercepted frames is associated with at least one service based on matching the at least one network event against a preconfigured service table mapping the at least one network event associated with an intercepted frame to the at least one service from among a plurality of services included in the preconfigured service table, wherein the ground network and the aerial network are the time-critical and mission-critical networks, wherein the at least one network event includes a virtual channel carrying traffic that always originates from the same source IP address and port number and directed to the same destination IP address and port number;
a processing unit for processing frames determined to be associated with the at least one service;
a queue for buffering frames; and
a traffic shaper for performing bandwidth management on frames stored in the queue.

13. A method for enabling efficient data communication between a ground network and an aerial network, comprising:
-
transparently intercepting a frame flowing between the ground network and the aerial network, wherein the frame is intercepted at a data link layer; determining if at least one service is associated with the intercepted frame based on matching at least one network event against a preconfigured service table; mapping the at least one network event associated with the intercepted frame to at least one service from among a plurality of services included in the preconfigured service table, wherein the at least one network event includes a virtual channel carrying traffic that always originates from the same source IP address and port number and directed to the same destination IP address and port number; processing the intercepted frame according to the at least one service being associated with the frame; and relaying the processed frame to a data link between the ground network and the aerial network, wherein the ground network and the aerial network are time-critical and mission-critical networks. - View Dependent Claims (14, 15, 16, 17)

18. A non-transitory computer readable medium having stored thereon computer executable code when executed causing a processor to perform the process of:
-
transparently intercepting a frame flowing between the ground network and the aerial network, wherein the frame is intercepted at a data link layer; determining if at least one service is associated with the intercepted frame based on matching the at least one network event against a preconfigured service table; mapping the at least one network event associated with the intercepted frame to the at least one service from among a plurality of services included in the preconfigured service table, wherein the at least one network event includes a virtual channel carrying traffic that always originates from the same source IP address and port number and directed to the same destination IP address and port number; processing the intercepted frame according to the at least one service being associated with the frame; and relaying the processed frame to a data link between the ground network and the aerial network, wherein the ground network and the aerial network are time-critical and mission-critical networks. - View Dependent Claims (19)
