Enhanced network communication using multiple network connections

A networking apparatus comprising:

• one or more processors;
• and
• one or more machine-readable media storing instructions that, when executed by the one or more processors, cause the networking apparatus to perform operations comprising:
• receiving, by the networking apparatus, one or more packets to be transmitted over the network, wherein the networking apparatus is configured to maintain connectivity to a network through each of multiple network transports;
• classifying, by the networking apparatus, the one or more packets to determine a class of service for the one or more packets from among a predetermined set of classes of service that includes classes of service that correspond to different latency constraints;
• calculating a first measure of expected latency for a first network transport of the multiple network transports indicating a first overall latency between adding a packet to the transmission queue and receipt of the packet over the first network transport;
• calculating a second measure of expected latency for a second network transport of the multiple network transports based at least on a second baseline latency indicating a second overall latency between adding a packet to the transmission queue and receipt of the packet over the second network transport;
• selecting, by the networking apparatus, one of the multiple network transports to transmit the one or more packets based on (i) the class of service for the one or more packets and (ii) the first measure of expected latency and the second measure of expected latency for transmission of the one or more packets over the respective multiple network transports, wherein the measures of expected latency are based at least in part on amounts of data queued to be transmitted over the respective network transports;
• and
• transmitting, by the networking apparatus, the one or more packets using the selected network transport.

One or more non-transitory machine-readable media storing instructions that, when executed by one or more processors of a networking apparatus, cause the networking apparatus to:

• receiving, by the networking apparatus, one or more packets to be transmitted over the network, wherein the networking apparatus is configured to maintain connectivity to a network through each of multiple network transports;
• classifying, by the networking apparatus, the one or more packets to determine a class of service for the one or more packets from among a predetermined set of classes of service that includes classes of service that correspond to different latency constraints;
• calculating a first measure of expected latency for a first network transport of the multiple network transports indicating a first overall latency between adding a packet to the transmission queue and receipt of the packet over the first network transport;
• calculating a second measure of expected latency for a second network transport of the multiple network transports based at least on a second baseline latency indicating a second overall latency between adding a packet to the transmission queue and receipt of the packet over the second network transport;
• selecting, by the networking apparatus, one of the multiple network transports to transmit the one or more packets based on (i) the class of service for the one or more packets and (ii) the first measure of expected latency and the second measure of expected latency for transmission of the one or more packets over the respective multiple network transports, wherein the measures of expected latency are based at least in part on amounts of data queued to be transmitted over the respective network transports;
• and
• transmitting, by the networking apparatus, the one or more packets using the selected network transport.
