  1. An API for Multipath Routing Aparna Srikanta Swamy CS522 Semester Project 12/05/01 API for Multipath Routing

  2. 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. API for Multipath Routing

  3. Overview • SERVER calls for single path routing to set up a connection • socket(), • bind(), • listen() & • accept(). • CLIENT calls : • socket() • and connect(). API for Multipath Routing

  4. 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. API for Multipath Routing

  5. MULTIPATH ROUTING Sender Receiver Proxy Server Multi path Sender Multi path Receiver Proxy Server API for Multipath Routing

  6. Multipath Sender Multipath Receiver Transmit Queue Receive Queue Frame Distributor Frame Collector Socket 1 Socket 2 Socket 1 Socket 2 Proxy Server Proxy Server API for Multipath Routing

  7. 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.
