Rangkaian tindanan yang dicipta secara dinamik melalui rangkaian IP asas digunakan secara meluas untuk menyampaikan kandungan multimedia kerana ia boleh menyediakan beberapa perkhidmatan tambahan yang boleh ditentukan pengguna. Laluan tindanan berbilang antara pasangan nod tindanan destinasi sumber direka untuk meningkatkan keteguhan perkhidmatan terhadap kegagalan dan turun naik lebar jalur rangkaian asas. Trafik multimedia boleh diedarkan ke atas berbilang laluan tersebut untuk memaksimumkan penggunaan laluan dan meningkatkan daya pemprosesan aplikasi. Kebanyakan algoritma penghalaan berasaskan aliran hanya mempertimbangkan metrik biasa seperti lebar jalur atau kelewatan laluan, yang mungkin berkesan untuk aplikasi data tetapi tidak untuk aplikasi masa nyata seperti Voice over IP (VoIP), di mana tahap metrik prestasi tersebut berbeza. mungkin memberikan tahap prestasi yang sama yang dialami oleh pengguna akhir. Kertas kerja ini memfokuskan pada rangkaian tindanan VoIP tersebut dan mencadangkan algoritma penghalaan aliran berasaskan laluan alternatif baharu menggunakan metrik trafik khusus aplikasi, iaitu "Kapasiti Laluan VoIP (VPCap)," untuk mengira bilangan maksimum aliran VoIP yang berpuas hati QoS yang mungkin diedarkan atas setiap laluan tindanan yang tersedia pada satu ketika. Keputusan simulasi membuktikan bahawa lebih banyak sesi VoIP yang berpuas hati QoS boleh diwujudkan melalui berbilang laluan tindanan yang sama, berbanding dengan pendekatan tradisional.

Abstract: Overlay networks which are dynamically created over underlying IP networks are becoming widely used for delivering multimedia contents since they can provide several additional user-definable services. Multiple overlay paths between a source-destination overlay node pair are designed to improve service robustness against failures and bandwidth fluctuation of the underlying networks. Multimedia traffic can be distributed over those multiple paths in order to maximize paths' utilization and to increase application throughputs. Most of flow-based routing algorithms consider only common metrics such as paths' bandwidth or delay, which may be effective for data applications but not for real-time applications such as Voice over IP (VoIP), in which different levels of such performance metrics may give the same level of the performance experienced by end users. This paper focuses on such VoIP overlay networks and proposes a novel alternative path based flow routing algorithm using an application-specific traffic metric, i.e. "VoIP Path Capacity (VPCap)," to calculate the maximum number of QoS satisfied VoIP flows which may be distributed over each available overlay path at a moment. The simulation results proved that more QoS-satisfied VoIP sessions can be established over the same multiple overlay paths, comparing to traditional approaches.

AB - Overlay networks which are dynamically created over underlying IP networks are becoming widely used for delivering multimedia contents since they can provide several additional user-definable services.
