This paper looks at the problem of multi-streaming in 3D teleimmersion and describes how a protocol architecture called CP (for Coordination Protocol) can be used to coordinate video frame transport between application clusters. CP provides application endpoints with information about current network conditions, and an open architecture for implementing application-specific coordination schemes. The scheme described in this paper apportions available bandwidth among flows such that frame transport synchrony, important for 3D reconstruction performance, is significantly enhanced. Results demonstrating the effectiveness of CP in increasing multi-stream coordination, while at the same time maintaining aggregate congestion responsiveness, are obtained from a FreeBSD/Linux implementation and a live experimental network. Results underscore the importance of consistency in network information across flows for realizing dramatic improvements in frame arrival synchrony. Categories and Sub...
