Abstract

A data processing system comprising: first and second network ports each operable to support a network connection configured according to one or more of a predetermined set of physical layer protocols; and a processor configured to, on a network message being formed for transmission to a network endpoint accessible over either of the first and second network ports: estimate the total time required to, for each of the predetermined set of physical layer protocols, negotiate a respective network connection and transmit the entire network message over that respective network connection; select the physical layer protocol having the lowest estimate of the total time required to negotiate a respective network connection and transmit the network message over that respective network connection; and configure at least one of the first and second network ports to use the selected physical layer protocol.

A data processing system comprising:

first and second network ports each operable to support a network connection configured according to one or more of a predetermined set of physical layer protocols;
and
a processor configured to, on a network message being formed for transmission to a network endpoint accessible over either of the first and second network ports, said first and second network ports connected to respective physical links:
estimate the total time required to, for each of the predetermined set of physical layer protocols, transmit the network message over a respective network connection;
select the physical layer protocol having the lowest estimate of the total time required to transmit the entire network message over a respective network connection;
and
configure at least one of the first and second network ports to use the selected physical layer protocol;
and wherein said data processor is configured to:
transmit in parallel said network message over both of a first of said physical links and a second of said physical links.
