METHOD AND APPARATUS FOR BANDWIDTH ADAPTIVE SCHEDULING IN CLOUD BASED VIRTUAL NETWORK FUNCTIONS FOR TRAFFIC OVER POINT-TO-POINT OVERLAY TUNNELS

Disclosed embodiments include computer-based adaptive schedulers, and methods for operating, for adaptively scheduling the flow of packets in a network, the adaptive scheduler including a queue communication module communicating with a queue of packets queued to be sent over the network, an ACK packet receiver module communicating with an ACK packet receiver and receiving information related to the number of ACK packets received by the ACK packet receiver, a transmit window module communicating with a packet transmitter and receiving information related to the number of bytes that can be transmitted and sets a transmit window duration for a packet in the queue to be transmitted and schedules the transmission of the packet in the queue by the packet transmitter and, a time window module that adaptively sets a duration for which the ACK packet receiver module will wait for ACK packets to be received by the ACK packet receiver.
