Network stack for transmission of application data over network connections

A non-transitory computer-readable medium with instructions stored thereon that, responsive to execution by a processing device, cause the processing device to perform operations comprising:

• receiving application data from each application of a plurality of applications, wherein the application data comprises a plurality of datagrams;
• determining a permitted data rate for each application of the plurality of applications based on a connection bit rate of a network connection and an allocation ratio that apportions available bandwidth of the network connection between the plurality of applications;
• shaping the application data received from each application of the plurality of applications based on the permitted data rate for the application into respective shaped application data;
• adding the shaped application data associated with each application to a queue;
• assigning the datagrams included in the queue to a particular data stream of a plurality of data streams based on metadata associated with each datagram;
• applying stream level flow control to each data stream of the plurality of data streams to identify a subset of datagrams from the each data stream in the queue;
• generating a packet for transmission over the network connection, wherein the packet includes the subset of datagrams from at least two data streams of the plurality of data streams;
• and
• transmitting the packet over the network connection.

A system comprising:

• a memory with instructions stored thereon;
• and
• a processing device, coupled to the memory, the processing device configured to access the memory and execute the instructions, wherein the instructions cause the processing device to perform operations comprising:
• receiving application data from each application of a plurality of applications, wherein the application data comprises a plurality of datagrams;
• determining a permitted data rate for each application of the plurality of applications based on a connection bit rate of a network connection and an allocation ratio that apportions available bandwidth of the network connection between the plurality of applications;
• shaping the application data received from each application of the plurality of applications based on the permitted data rate for the application into respective shaped application data;
• adding the shaped application data associated with each application to a queue;
• assigning the datagrams included in the queue to a particular data stream of a plurality of data streams based on metadata associated with each datagram;
• applying stream level flow control to each data stream of the plurality of data streams to identify a subset of datagrams from the each data stream in the queue;
• generating a packet for transmission over the network connection, wherein the packet includes the subset of datagrams from at least two data streams of the plurality of data streams;
• and
• transmitting the packet over the network connection.
