Network offloading with reduced packet loss

摘要

The invention relates to a method of transmitting a first segment of data via a data network from a transmitting unit having a first data transmission rate to a first destination having a first data reception rate. Where the first data transmission rate is larger than the first data reception rate, the method comprising: effectively reducing the first transmission rate from the transmitting unit to the first destination by switching between transmitting at least a part of the first segment as one or more data packets to the first destination in a direction only from the transmitting unit to the first destination, and transmitting at least a part of second segment as one or more data packets to one or more additional destinations in a direction only from the transmitting unit to the one or more additional destinations, the switching being repeated until said first segment and/or at least said second segment has been transmitted. In this way, the packet rate to a client is reduced while the total packet rate for the transmitting system is maintained whereby a decreased probability of packet loss and/or of router buffer exhaustion is achieved since data to relatively slower client will not be transmitted at full rate.

1. A method of transmitting a first segment of data and a second segment of data, the method comprising:
(A) transmitting at least a part of said first segment of data in one or more data packets from a transmitting unit to a first destination, a transmission rate of said transmitting unit being greater than a reception rate of said first destination; (B) transmitting at least a part of said second segment of data as one or more different data packets from the transmitting unit to one or more additional destinations, said first segment of data and said second segment of data including different data; and switching between steps A and B until said first segment and/or at least said second segment has been transmitted, which results in effectively reducing said transmission rate from said transmitting unit to said first destination.
