Message reordering timers

A system for data communication over a data channel coupling a plurality of nodes, the system comprising:

• a second node of the plurality of nodes configured to
• receive data messages, the data messages belonging to a set of data messages transmitted in a sequential order from a first node,
• send feedback messages to the first node, the feedback messages characterizing a delivery status of the set of data messages at the second node, including
• maintaining a set of one or more timers according to occurrences of a plurality of delivery order events, the maintaining including modifying a status of one or more timers of the set of timers based on occurrences of the plurality of delivery order events, and
• deferring sending of said feedback messages until expiry of one or more of the set of one or more timers.

Software stored on non-transitory computer-readable media comprising instructions for causing a second node in a data communication system to:

• receive data messages at the second node, the messages belonging to a set of data messages transmitted in a sequential order from the first node;
• send feedback messages from the second node to the first node, the feedback messages characterizing a delivery status of the set of data messages at the second node, including
• maintaining a set of one or more timers according to occurrences of a plurality of delivery order events, the maintaining including modifying a status of one or more timers of the set of timers based on occurrences of the plurality of delivery order events, and
• deferring sending of said feedback messages until expiry of one or more of the set of one or more timers.

A method for data communication from a first node to a second node over a data channel coupling the first node and the second node, the method comprising:

• receiving, at the first node, feedback messages indicative of a delivery status of a set of data messages transmitted in a sequential order to the second node from the second node;
• maintaining a size of a congestion window at the first node including
• maintaining a set of one or more timers according to occurrences of a plurality of feedback events, the maintaining including modifying a status of one or more timers of the set of timers based on occurrences of the plurality of feedback events;
• and
• delaying modification of the size of the congestion window until expiry of one or more of the set of one or more timers.

A system for data communication between a plurality of nodes over a data channel coupling the plurality of nodes, the system comprising:

• a first node of the plurality of nodes configured to:
• receive, at the first node, feedback messages indicative of a delivery status of a set of data messages transmitted in a sequential order to the second node from the second node;
• maintain a size of a congestion window at the first node including
• maintaining a set of one or more timers according to occurrences of a plurality of feedback events, the maintaining including modifying a status of one or more timers of the set of timers based on occurrences of the plurality of feedback events;
• and
• delaying modification of the size of the congestion window until expiry of one or more of the set of one or more timers.
