Abstract
A method for weighted routing of data traffic can include generating a first hash value based on a header of a data packet and performing a lookup in a first equal cost multi-path (ECMP) table using the first hash value to select a secondary ECMP table. The first ECMP table can include a weighted listing of at least two secondary ECMP tables. The method can further include generating a second hash value based on the header of the data packet and performing a lookup in the selected secondary ECMP table based on the second hash value to select an egress port of a plurality of egress ports of the data switch. The method can further include forwarding the data packet on the selected egress port.
