Network-friendly transmission control protocol (TCP) methods, apparatus and articles of manufacture

摘要

Example methods, apparatus and articles of manufacture to route policy requests are disclosed. A disclosed example method includes sending bandwidth probe packets at a probing rate, receiving a packet containing an indication representative of whether the probe packets triggered congestion, and selecting a transmission rate for sending data packets based on the probing rate and the indication.

主权项

1. A method comprising:
sending first bandwidth probe packets at a first probing rate, the first probing rate being a different parameter than a data packet transmission rate at which data packets are sent, the first bandwidth probe packets being a different type of packet than the data packets; in response to receiving a first packet containing a first indication that the first bandwidth probe packets triggered first congestion, estimating a first available bandwidth for the data packets based on the first probing rate and the first indication; selecting a value for the data packet transmission rate based on a percentage of the first estimated available bandwidth; sending second bandwidth probe packets at a second probing rate; in response to receiving a second packet containing a second indication that the second bandwidth probe packets triggered second congestion, estimating a second available bandwidth for the data packets based on the second probing rate; and adjusting the data packet transmission rate based on the second estimated available bandwidth.
