BIRP: Bank intra routing protocol

SWIFT is a financial institution, which provides an interface for banks in order to communicate and transfer money worldwide. These banks, together with their branches incur significant expenses including security infrastructure, SAA package license, yearly maintenance, and message costs. Banks always look for a good investment and the swift routing protocol does not deal with intra bank message processing as a separate case. If a message is sent for either a branch or another bank, it must pass through SWIFT before it continues to the correspondent. In this work, we provide a new protocol - bank intra routing protocol (BIRP) - that intra routes all messages exchanged between the main branch and all its branches.
