Aparna SrikantaswamyAPI for Multipath Routing2 What is an API ? An Application Program Interface (API) allows application programs such as FTP, Telnet, Web browsers, etc., to access certain resources through a predefined and preferably consistent interface.

Aparna SrikantaswamyAPI for Multipath Routing3 Overview SERVER calls for single path routing to set up a connection socket(), bind(), listen() & accept(). CLIENT calls : socket() and connect().

Aparna SrikantaswamyAPI for Multipath Routing4 To provide Multi path connection Modify these function calls. MULTIPATH SENDER - Sending side : Data written by the sender has to be distributed across multiple connections. MULTIPATH RECEIVER - Receiving side : Packets from multiple connections have to be correlated and delivered to the receiver in the same order as received.

Aparna SrikantaswamyAPI for Multipath Routing7 Design The library will have the following functions :- mp_socket(), mp_bind(), mp_listen(), mp_accept(), mp_connect(), mp_write(), mp_read(). The library should allow the sender to express the list of connection relay proxy servers used. The proxy server takes the connection request with the message indicating the destination and issues a connection request to the multi path receiver.
