Abstract
A first data packet of a data flow may be addressed to a primary address and include information for the data flow and a bucket ID may be computed based on the information. Responsive to the bucket ID mapping to first and second servers and the first data packet being addressed to the primary address, the first data packet may be transmitted to the first server. A second data packet may be received addressed to a stand-by address and including the information for the data flow, and a bucket ID may be computed based on the information with the bucket IDs for the first and second packets being the same. Responsive to the bucket ID for the second data packet mapping to first and second servers and the second data packet being addressed to the stand-by address, the second data packet may be transmitted to the second server.
