Abstract:
1. A method for selection of a route for transmission of data packets from a source network site to a destination network site, said method comprising at least steps of: providing the source network site with a first plurality of network service provider connections connecting the source network site to a network; providing the destination network site with a second plurality of network service provider connections connecting the destination network site to said network; determining, at the source network site, at least one of a round trip time value and a packet success rate value for each combination of individual source and destination network service provider connections which are configurable among said first and second plurality of network service provider connections; selecting, at the source network site, a first network service provider connection among said first plurality of network service provider connections and a second network service provider connection among said second plurality of network service provider connections on the basis of at least one of said round trip time value determined at said source network site for each said combination of source and destination network service provider connections, and/or said packet success rate value determined at said source network site for each combination of source and destination network service provider connections; reducing, as a function of time, an amount of change in the packet success rate and/or round trip time of a connection required to cause a change in the route selection, said function of time being a piecewise linear function.
