Partitioning data sets for transmission on multiple physical links
First Claim
1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising to:
- receive, by a first network device, a particular data set addressed to a client device;
partition, by the first network device, the particular data set into at least a first subset of data and a second subset of data;
encapsulate, by the first network device, the first subset of data and the second subset of data each with a unique sequence number, wherein each unique sequence number is based at least in part on a first set of sequence numbers specified in an outer header of the particular data set prior to receipt by the first network device and a second set of sequence numbers specified in an inner header of the particular data set prior to receipt by the first network device;
encapsulate the first subset of data using a first header assigned by the first network device;
encapsulate the second subset of data using a second header assigned by the first network device, wherein the first header is different from the second header;
determine, based on the difference between the first header and the second header, that data with the first header is transmitted on a first physical link and data with the second header is transmitted on a second physical link different than the first physical link; and
transmit the first subset of data with the first header and the second subset of data with the second header.

Abstract
The present disclosure discloses a method and a network device for partitioning data sets for transmission on multiple physical links in a network. Specifically, a network device receives a particular data set addressed to a client device. The network device partitions the particular data set into at least a first subset of data and a second subset of data. Then, the network device encapsulates the first subset of data using a first header and encapsulating the second subset of data using a second header that results in (a) data with the first header being transmitted on a first physical link and (b) data with the second header being transmitted on a second physical link different than the first physical link. Finally, the network device transmits the first subset of data with the first header and the second subset of data with the second header.
