Connectionless reliable transport

A computer-implemented method for operating a transport layer in a computing device on a network, comprising:

• receiving a message for outputting onto the network, wherein the message is associated with a transmitting application executing on the computing device;
• receiving a transport context associated with the message, wherein the transport context associates the transmitting application with a receiving application on a second computing device on the network;
• generating a plurality of packets including data from the message;
• adding the plurality of packets to a packet flow associated with the transport context, wherein each packet in the packet flow is assigned a sequence number;
• outputting the plurality of packets for transmission onto the network without establishing a connection with the second computing device;
• and
• monitoring, using the transport context, a status for each packet from the plurality of packets, wherein monitoring includes determining, using sequence numbers from the plurality of packets, whether each packet from the plurality of packets was received at the second computing device.

A computer-implemented method for operating a transport layer in a computing device on a network, comprising:

• receiving a plurality of packets associated with a first computing device on the network, each packet from the plurality of packets including a sequence number, wherein the plurality of packets are received without an established connection with the first computing device;
• determining that the plurality of packets are associated with a packet flow, wherein packets in the packet flow are sent by a transmitting application executing on the first computing device for receipt by a receiving application executing on the computing device;
• obtaining a transport context associated with the packet flow, wherein the transport context associates the transmitting application with the receiving application;
• determining, using sequence numbers from the plurality of packets, whether the plurality of packets were received in order;
• outputting a response message for transmission onto the network, the response message indicating whether the plurality of packets were received in order, wherein the response message is output without establishing a connection with the first computing device;
• and
• outputting the plurality of packets for receipt by the receiving application, wherein the plurality of packets are output in an order in which the plurality of packets was received.

A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors of a computing device on a network, cause the one or more processors to perform operations including:

• receiving a message for outputting onto the network, wherein the message is associated with a transmitting application executing on the computing device;
• receiving a transport context associated with the message, wherein the transport context associates the transmitting application with a receiving application on a second computing device on the network;
• generating a plurality of packets including data from the message;
• adding the plurality of packets to a packet flow associated with the transport context, wherein each packet in the packet flow is assigned a sequence number;
• outputting the plurality of packets for transmission onto the network without establishing a connection with the second computing device;
• and
• monitoring, using the transport context, a status for each packet from the plurality of packets, wherein monitoring includes determining, using sequence numbers from the plurality of packets, whether each packet from the plurality of packets was received at the second computing device.
