Control of congestion in a network between a transmission source and a transmission destination is provided, including receiving, at the transmission source, a packet transmission acknowledgment associated with a transmission packet of a data stream received at a transmission destination, incrementing a first window resize counter based on a congestion indicator, determining that a window resize condition is satisfied based on the incrementing of the first window resize counter and resizing, based on satisfaction of the window resize condition, a transmission window of the data stream. The packet transmission acknowledgment includes the congestion indicator, which represents whether network traffic experienced by the transmission packet between the transmission source and the transmission destination satisfies a congestion condition. The transmission window represents a maximum number of packets permitted to be transmitted from the transmission source and concurrently unacknowledged as received by the transmission destination.

Network congestion control

A computing system for transport layer network recovery on a packet-switched computer network includes a source computing device with a processor that executes a network traffic communication module, a load balancing module, and a congestion control module. The network traffic communication module provisions a plurality of source ports to transmit outbound packets to a destination computing device, each source port being associated with a respective network path. The load balancing module assigns each outbound packet to one of the source ports using a port scheduling algorithm to uniformly distribute the packets among the source ports and associated network paths. The congestion control module detects a congestion control condition for a packet transmitted via a source port associated with a congested network path. The load balancing module assigns a next source port for a next outbound packet from a remainder of the source ports not associated with the congested network path.
