Simple and resource-efficient resilient network systems

A method for providing a resilient multi-path connection between edge devices of a communication network, comprising:

• calculating connection-specific traffic distribution functions of the multi-path connection based upon path failure patterns of the multi-path connection;
• selecting a traffic distribution function of the multi-path connection based upon the calculated connection-specific traffic distribution functions and based upon current path failure pattern of the multi-path connection;
• and
• distributing traffic into corresponding paths of the multi-path connection based upon the selected traffic distribution function.

An edge device for providing a resilient multi-path connection between edge devices of a communication network, comprising:

• a calculator that calculates connection-specific traffic distribution functions of the multi-path connection based upon path failure patterns of the multi-path connection;
• a selector that selects a traffic distribution function of the multi-path connection based upon the calculated connection-specifc traffic distribution functions and based upon current path failure pattern of the multi-path connection;
• and
• a distributor that distributes traffic into corresponding paths of the multi-path connection based upon the selected traffic distribution function.

A computer program product for providing a resilient multi-path connection between edge devices of a communication network, comprising:

• a program subroutine for calculating connection-specific traffic distribution functions of the multi-path connection based upon path failure patterns of the multi-path connection;
• a program subroutine for selecting a traffic distribution function of the multi-path connection based upon the calculated connection-specific traffic distribution functions and based upon current path failure pattern of the multi-path connection;
• and
• a program subroutine for distributing traffic into corresponding paths of the multi-path connection based upon the selected traffic distribution function.
