Abstract

An apparatus configured to perform resilient data plane processing using multiple network streams may comprise a memory and a processor communicatively coupled to one another. The processor may be configured to establish a connection with the data aggregator, and request access to one or more resources from a data aggregator. Further, the processor may be configured to receive a first data stream and a second data stream from the data aggregator, combine a version of the first data stream and a version of the second data stream into a local data stream, and present the local data stream.

First claim

The invention claimed is:

1. An apparatus, comprising:
a memory configured to store:
a local profile configured to indicate an association with a data aggregator configured to split one or more data streams; and

a processor communicatively coupled to the memory and configured to:
establish a connection with the data aggregator;
request access to one or more resources from the data aggregator, the data aggregator being configured to obtain the one or more resources and split the one or more resources into a first data stream comprising a first plurality of data packets and a second data stream comprising a second plurality of data packets;
upon performing a first plurality of network operations, receive the first data stream;
upon performing a second plurality of network operations, receive the second data stream;
determine whether the first plurality of data packets and the second plurality of data packets are of a same type;
in response to determining that the first plurality of data packets and the second plurality of data packets are the same type, determine that the second plurality of data packets are configured to replicate the first plurality of data packets;
in response to determining that the first plurality of data packets and the second plurality of data packets are not the same type, determine that the second plurality of data packets are configured to supplement the first plurality of data packets;
combine a version of the first data stream and a version of the second data stream into a local data stream; and
present the local data stream.

2. The apparatus of claim 1 , wherein:
the first data stream comprises a first bandwidth;
the first data stream is received via a first network device configured to forward the first data stream between the data aggregator and the apparatus using a first Quick UDP Internet Connections (QUIC) relay;
the first network device receives the first data stream via one or more cellular communications from the data aggregator;
the first plurality of network operations comprise one or more short-range wireless communications;
the second data stream comprises a second bandwidth;
the second bandwidth is greater than the first bandwidth;
the second data stream is received via a second network device configured to forward the second data stream between the data aggregator and the apparatus using a second QUIC relay;
the second network device receives the second data stream via one or more internet communications from the data aggregator; and
the second plurality of network operations comprise one or more additional internet communications.

3. The apparatus of claim 2 , wherein:
the first QUIC relay is a first portion of a transport layer network protocol configured to multiplex data between the data aggregator and the apparatus; and
the second QUIC relay is a second portion of the transport layer network protocol configured to multiplex data between the data aggregator and the apparatus.

4. The apparatus of claim 1 , wherein:
the processor is further configured to:
in conjunction with determining that the second plurality of data packets are configured to replicate the first plurality of data packets, determine whether the second plurality of data packets comprise the first plurality of data packets;
in response to determining that the second plurality of data packets do not comprise the first plurality of data packets, determine packet loss on the second data stream; and
receive a packet loss-corrected data stream from the data aggregator;

the first data stream is the version of the first data stream received upon performing the first plurality of network operations; and
the packet loss-corrected data stream is the version of the second data stream configured to correct the packet loss on the second data stream.

5. The apparatus of claim 1 , wherein:
the processor is further configured to:
in conjunction with determining that the second plurality of data packets are configured to replicate the first plurality of data packets, determine whether the second plurality of data packets comprise the first plurality of data packets; and
in response to determining that the second plurality of data packets comprise the first plurality of data packets, determine no packet loss on the second data stream;

the version of the first data stream is the first data stream received upon performing the first plurality of network operations; and
the version of the second data stream is the second data stream received upon performing the second plurality of network operations.

6. The apparatus of claim 1 , wherein:
the first data stream is a video parity stream;
the first data stream is received via a first network device configured to forward the first data stream between the data aggregator and the apparatus;
the first network device receives the first data stream via one or more cellular communications from the data aggregator;
the first plurality of network operations comprise one or more short-range wireless communications;
the second data stream is a high-definition video stream;
the second data stream is received via a second network device configured to forward the second data stream between the data aggregator and the apparatus;
the second network device receives the second data stream via one or more internet communications from the data aggregator; and
the second plurality of network operations comprise one or more additional internet communications.

7. The apparatus of claim 1 , wherein:
the first data stream comprises a first bandwidth;
the first data stream is received from the data aggregator upon performing a first plurality of multipath Quick UDP Internet Connections (QUIC) operations;
the first plurality of network operations comprise one or more cellular communications;
the second data stream comprises a second bandwidth;
the second bandwidth is greater than the first bandwidth;
the second data stream is received via a network device configured to forward the second data stream between the data aggregator and the apparatus upon performing a first plurality of multipath QUIC operations;
the network device receives the second data stream via one or more internet communications from the data aggregator; and
the second plurality of network operations comprise one or more additional internet communications.

8. A method, comprising:
establishing a connection with a data aggregator configured to split one or more data streams;
requesting access to one or more resources from the data aggregator, the data aggregator being configured to obtain the one or more resources and split the one or more resources into a first data stream comprising a first plurality of data packets and a second data stream comprising a second plurality of data packets;
upon performing a first plurality of network operations, receiving the first data stream;
upon performing a second plurality of network operations, receiving the second data stream;
determining whether the first plurality of data packets and the second plurality of data packets are of a same type;
in response to determining that the first plurality of data packets and the second plurality of data packets are the same type, determining that the second plurality of data packets are configured to replicate the first plurality of data packets;
in response to determining that that the first plurality of data packets and the second plurality of data packets are not the same type, determining that the second plurality of data packets are configured to supplement the first plurality of data packets;
combining a version of the first data stream and a version of the second data stream into a local data stream; and
