  • Mobile Data Management - Effects and Performance of Content Negotiation Based on CC/PP
    Mobile Data Management, 2001
    Co-Authors: Kinuko Yasuda, Takuya Asada, Tatsuya Hagino
    Abstract:

    We describe our investigation of the effectiveness ofWeb content negotiation using CC/PP. CC/PP is a proposed specification on a user-side content negotiation framework to comply with various Clients. CC/PP is based on common technologies such as XML and HTTP extension and is expected to provide a generic content negotiation solution, but neither its performance nor effectiveness has ever been shown. We have implemented a CC/PP capable Web browser and a CC/PP proxy, and measured the performance of CC/PP and various different settings. The result shows that the use of indirect reference and abbreviating profile-diffs have good improvements on retrieval time when the Client Connection is as narrow as cellular phones. When the Connection is faster than that, the use of inline encoding would be better provided that the profile size is less than a certain threshold, in our tests, approximately one-tenth the value of effective bandwidth of the Client Connection. The observed traffic with content conversion by CC/PP was smaller than the case without CC/PP for all tested environments, and the retrieval time is better or comparable for cellular phone Clients. The result confirms that CC/PP is an effective solution for general content negotiation.

  • Migratory TCP: Connection migration for service continuity in the Internet
    Proceedings 22nd International Conference on Distributed Computing Systems, 2002
    Co-Authors: F. Sultan, D. Iyer, K Srinivasan, Liviu Iftode
    Abstract:

    Today's Internet services are commonly built over TCP, the standard Internet Connection-oriented reliable transport protocol. The endpoint naming scheme of TCP, based on network layer (IP) addresses, creates an implicit binding between a service and the IP address of a server providing it, throughout the lifetime of a Client Connection. This makes a TCP Client prone to all adverse conditions that may affect the server endpoint or the internetwork in between, after the Connection is established: congestion or failure in the network, server overloaded, failed or under DoS attack. Studies that quantify the effects of network stability and route availability demonstrate that connectivity failures can significantly impact Internet services. As a result, although highly available servers can be deployed, sustaining continuous service remains a problem. We propose cooperative service model, in which a pool of similar servers, possibly geographically distributed across the Internet, cooperate in sustaining a service by migration of Client Connections within the pool. The control traffic between servers, needed to support migrated Connections, can be carried either over the Internet or over a private network. From Client's viewpoint, at any point during the lifetime of its service session, the remote endpoint of its Connection may transparently migrate between servers.

  • NEW2AN - Architecture of Data Exchange with Minimal Client-Server Interaction at Multipoint Video Conferencing
    Lecture Notes in Computer Science, 2014
    Co-Authors: Anton Saveliev, Irina Vatamaniuk, Andrey Ronzhin
    Abstract:

    The problems of serverless Connections between Clients and audiovisual data transmission in peer-to-peer videoconferencing web application are discussed. The serverless Connections based on the WebRTC protocol allow applications to transfer any data between Clients directly. The partial or complete loss of service data for the WebRTC protocol, which hampers the Client Connection, occurs during interaction of several Clients through the server of the videoconferencing application. The proposed architecture of data transmission and storage on Client and server provides buffering and following processing of the signal data with the exception of their loss and support of interaction between Client groups.
