Abstract

The DSCP Mirroring System enables the automatic reuse of the Differentiated Services Code Point header by the user devices that are served by a network to enable delivery of wireless services to the individually identified user wireless devices and manage the various data traffic and classes of data to optimize or guarantee performance, low latency, and/or bandwidth without the overhead of the management of the Differentiated Services Code Point header.

Claims

1. A Differentiated Services Code Point Mirroring System for processing IP packet traffic exchanged between wireless devices, which are located onboard an aircraft and served by an aircraft network, and a ground-based Access Network, which exchanges communication signals with ground-based communication network servers, comprising:

an IP packet receiver for identifying a Differentiated Services Code Point value stored in a header of an IP packet received by said wireless device; and

a Differentiated Services Code Point mirroring process for inserting said identified Differentiated Services Code Point value into the header of an IP packet generated by the wireless device in response to said received IP packet.

2. The Differentiated Services Code Point Mirroring System of claim 1, further comprising:

a Service Control Engine for setting a traffic policy for each stream/flow based on the traffic policies set per wireless device for data traffic between the wireless device and an IP destination server.

3. The Differentiated Services Code Point Mirroring System of claim 1, further comprising:

a Service Control Engine for prioritizing the data traffic in the direction the packet is routed.

4. A Differentiated Services Code Point Mirroring Process for processing IP packet traffic exchanged between wireless devices, which are located onboard an aircraft and served by an aircraft network, and a ground-based Access Network, which exchanges communication signals with ground-based communication network servers, comprising:

identifying a Differentiated Services Code Point value stored in a header of an IP packet received by the wireless device; and

inserting said identified Differentiated Services Code Point value into the header of an IP packet generated by the wireless device in response to said received IP packet.

5. The Differentiated Services Code Point Mirroring Process of claim 4, further comprising:

setting a traffic policy for each stream/flow based on the traffic policies set per wireless device for data traffic between the wireless device and an IP destination server.

6. The Differentiated Services Code Point Mirroring Process of claim 4, further comprising:

prioritizing the data traffic in the direction the packet is routed.

7. A Differentiated Services Code Point Mirroring System for processing IP packet traffic received by wireless devices, which are served by a network, comprising:

an IP packet receiver, located in a router which serves the wireless device, for identifying a Differentiated Services Code Point value stored in a header of a received IP packet; and

a Differentiated Services Code Point Mirroring Process, located in a router which serves the wireless device, for inserting said identified Differentiated Services Code Point value into the header of an IP packet generated in response to said received IP packet.

8. The Differentiated Services Code Point Mirroring System of claim 7, further comprising:

a Service Control Engine for setting a traffic policy for each stream/flow based on the traffic policies set per wireless device for data traffic between the wireless device and an IP destination server.

9. The Differentiated Services Code Point Mirroring System of claim 8, further comprising:

a Service Control Engine for prioritizing the data traffic in the direction the packet is routed.

10. A Differentiated Services Code Point Mirroring Process for processing IP packet traffic received by wireless devices, which are served by a network, comprising:

identifying, in a router which serves the wireless device, a Differentiated Services Code Point value stored in a header of a received IP packet; and

inserting, in a router which serves the wireless device, said identified Differentiated Services Code Point value into the header of an IP packet generated in response to said received IP packet.

11. The Differentiated Services Code Point Mirroring process of claim 10, further comprising:

setting a traffic policy for each stream/flow based on the traffic policies set per wireless device for data traffic between the wireless device and an IP destination server.

12. The Differentiated Services Code Point Mirroring Process of claim 11, further comprising:

prioritizing the data traffic in the direction the packet is routed.
