Learning machine-based mechanism to improve QoS dynamically using selective tracking of packet retransmissions

摘要

In one embodiment, a packet to be transmitted along a communication path in a network from a source to a destination is determined, the communication path having one or more hops between the source and the destination. An instruction is sent to one or more tracking nodes along the communication path to track a number of local retransmissions required to successfully transmit the packet from each tracking node to a respective next-hop destination. Then, reports indicating the number of local retransmissions are received from the one or more tracking nodes.

1. A method, comprising:
determining a packet to be transmitted along a communication path in a network from a source to a destination, the communication path having one or more hops between the source and the destination; sending an instruction to one or more tracking nodes along the communication path to track a number of local retransmissions required to successfully transmit the packet from each tracking node to a respective next-hop destination; and receiving, from the one or more tracking nodes, reports indicating the number of local retransmissions.
