1. The document proposes a new protocol called Connection Initiation Protocol (CIP) to improve performance for real-time streaming data transmission over networks. 2. CIP would encapsulate basic connection management tasks and be used alongside RTP for streaming data and RTCP for control signaling. 3. Unlike SIP-based systems, using CIP would reduce network traffic and improve performance for real-time data delivery by establishing a virtual communication channel between parties before transmitting streaming data and not involving the CIP server for RTP/RTCP transmission.

2. Real time streaming data transmission technology offers an opportunity to design global multimedia communication system between different clients in a network. Internet Telephony, Voice over IP are some applications of this technology. Introduction

3. Through this paper it is our endeavor to describe the basic architecture and application layer protocols that are specific to our application model for streaming data transmission . In this paper we have proposed a new Connection initiation scheme - Connection Initiation Protocol(CIP) to provide better performance in terms of network traffic and real time delivery of streaming data.

4. Figure 1: the protocol stack for this application.

5. CIP encapsulates the basic connection management tasks. CIP is used along with RTP (for streaming data transmission) and RTCP (for Control Signaling). RTP is used to transmit audio/video over unicast or multicast packet network service. RTP provides mechanisms for handling the problems of jitter and loss, timing recovery and intermedia synchronization. RTP implements audio/video encoding schemes(MPEG-2/ADPCM). Application Layer Protocols

6. RTCP is used for controlling the media streams. It monitors the QOS at the Receiver, conveys the reports and information about other participants to the sender. It accompanies RTP. SIP is an application layer protocol that can be used to establish, modify and terminate multimedia sessions with one or more participants. These sessions can be Internet Telephony call,videoconferencing or a distance-learning session . CIP resembles with SIP (Session Initiation Protocol) in certain operations but differs from it in the basic architecture.

7. Basic Operation This application integrates CIP, RTP and RTCP . In the application layer, the Connection Manager operates according to the rules of CIP (Connection Initiation Protocol). Client can originate “LOGGING” request using UDP connection. Accordingly, the Connection manager includes the current user( name,ip address,media info.) in the list of “available clients”. On successful logging and registration, the client receives a list of users already logged in. Connection manager maintains this list and sends a dynamically modified copy to each of the logged client.

8. After receiving the list of available clients, an user can send an “INVITE” request to another available client through the Connection Manger using UDP. Subsequently the inviting client opens an RTCP port to listen to the “ACKNOWLEDGE” from the actual recipient of the “INVITE” request .

9. Connection manager forwards the “INVITE” request to the proper destination. The invited client sends the “ACKNOWLEDGE” response to the inviting client as the first RTCP packet. On receiving the acknowledgement, an RTP session is to be established between the participating clients for the streaming data transfer.
