SYSTEMS AND METHODS FOR INTEGRATION OF IP-BASED DATA LINK MANAGEMENT IN EXISTING AVIONICS ARCHITECTURES
First Claim
1. A communications management unit, comprising:
- a legacy router providing access to a first set of air-ground data links;
an internet protocol router providing access to a second set of air-ground data links;
an applications and routing policy that provides criteria for selecting of a data link from one of the first set of air-ground data links or the second set of air-ground data links; and
a data link manager that selects the data link from either the first set of air-ground data links and second sets of air-ground data links based on information provided by the applications and routing policy and controls the legacy router and the internet protocol router to route communication messages via the selected data link.

Abstract
Systems and methods for integration of IP-based data link management in existing avionics architectures are provided. In one embodiment, a communications management unit comprises: a legacy router providing access to a first set of air-ground data links; an internet protocol router providing access to a second set of air-ground data links; an applications and routing policy that provides criteria for selecting of a data link from one of the first set of air-ground data links or the second set of air-ground data links; and a data link manager that selects the data link from either the first set of air-ground data links and second sets of air-ground data links based on information provided by the applications and routing policy and controls the legacy router and the internet protocol router to route communication messages via the selected data link.

10. A method for selecting a data link for a communications message, comprising:
-
receiving an indication at a data link manager that the communications message is ready to be transmitted; determining a communications criteria of the communications message, wherein the communications criteria is based on an applications and routing policy that indicates whether the communications message can be sent over an internet protocol data link; and selecting a data link from a set of legacy air-ground data links and a set of internet protocol based air-ground data links based on the communications criteria. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A communication system, comprising:
-
a communications manager unit that includes a legacy router, an internet protocol router, an applications and routing policy that provides criteria for the selection of a data link for a communication message, and a data link manager; wherein the data link manager selects the data link from among a set of legacy data links and a set of internet protocol data links based on the applications and routing policy; at least one legacy aeronautical radio coupled to the legacy router and configured to provide at least one of the set of legacy data links; and broadband service equipment coupled to the internet protocol router and configured to provide at least one of the set of internet protocol data links. - View Dependent Claims (18, 19, 20)
