Towards a scalable, adaptive and network-aware content distribution network
Chen, Yan.

Towards a scalable, adaptive and network-aware content distribution network [electronic resource] - 215 p.

Chair: Randy H. Katz.

Thesis (Ph.D.)--University of California, Berkeley, 2003.

Finally, to demonstrate the effectiveness of the monitoring services, we develop a adaptive overlay streaming media system which leverages our monitoring services for real-time path congestion/failure information, and an overlay network for adaptive packet relaying and buffering within the delivery infrastructure. (Abstract shortened by UMI.)

520 # $a Finally, to demonstrate the effectiveness of the monitoring services, we develop a adaptive overlay streaming media system which leverages our monitoring services for real-time path congestion/failure information, and an overlay network for adaptive packet relaying and buffering within the delivery infrastructure. (Abstract shortened by UMI.)
520 # $a First, we propose a novel simulation-based network Denial of Service (DoS) resilience benchmark, and apply it to evaluate and compare the centralized, replicated, and emerging distributed object location services.
520 # $a Fourth, to provide a general foundation for applications to take advantage of network awareness, we develop a scalable overlay network measurement and monitoring system with two components: Internet Iso-bar for latency estimation, and TOM (Tomography-based Overlay network Monitoring) for loss rate estimation.
520 # $a SCAN has four components: object location, replica placement and update multicast tree construction, replica management, and overlay network monitoring services.
520 # $a Second, we propose the first algorithm that dynamically places close to optimal number of replicas while meeting client QoS and server resource constraint, with overlay network topology only.
520 # $a TOM selectively monitors and measures the loss rates of a minimal basis set of O(n log n) linearly independent paths, and then applies them to estimate the loss rates of all other paths.
520 # $a The Internet has evolved to become a critical commercial infrastructure for service delivery. However, the Internet being an enormous, highly-dynamic, heterogeneous, and untrusted environment raises several challenges for building Internet-scale services (such as content delivery) with good scalability, efficiency, agility and security. In this thesis, we explore these issues by developing a scalable, adaptive and network-aware infrastructure for efficient content delivery, namely Scalable Content Access Network (SCAN).
520 # $a Third, we apply cooperative clustering-based replication to SCAN, which achieves comparable users' perceived performance to the conventional CDNs, while having only 4--5% of replication and update traffic, and 1--2% of the computation and replica management cost.
