Bulk multicast data transfer – towards the integration of FEC and ARQ using a lightweight feedback control tree
This paper describes the design of a reliable multicast framework which integrates FEC and receiverinitiated retransmit to ensure reliability. A dynamically elected control tree is used to aggregate the NAKs and tackle the NAK implosion problem. Both techniques support flow and congestion control to enable efficient, high data rate multicast data transfer as performance measurements with our pr...
متن کاملDesign of a Scalable Reliable Multicast Transport Protocol on the Design of a New Scalable Reliable Multicast Transport Protocol
This document presents the design and performance evaluation of a scalable, reliable, oneto-many multicast transport protocol. We show through simulation that it scales extremely well to a very big number of receivers. The server load (in terms of CPU and memory) is nearly independent of the number of receivers. Reliability is achieved using forward error correction (FEC) in combination with se...
متن کاملScalable Data Multicast Using Expanding Window Fountain Codes
Digital Fountain (DF) codes were introduced as an efficient and universal Forward Error Correction (FEC) solution for data multicast over lossy packet networks. However, in real-time applications, the DF encoder cannot make use of the “rateless” property as it was proposed in the DF framework, due to its delay constraints. In this scenario, many receivers might not be able to collect enough enc...
متن کاملVideo multicast using layered FEC and scalable compression
The use of scalable video with layered multicast has been shown to be an effective method to achieve rate control in heterogeneous networks. In this paper, we propose the use of layered FEC as an error control mechanism in a layered multicast framework. By organizing FEC into multiple layers , receivers can obtain different levels of protection commensurate with their respective channel conditi...
متن کاملPerformance analysis of burst-mode receivers with clock phase alignment and forward error correction for GPON
We experimentally demonstrate the performance analysis of burst-mode receivers (BMRx) in a 622 Mb/s 20-km gigabit-capable passive optical network (GPON) uplink. Our receiver features automatic phase acquisition using a clock phase aligner (CPA), and forward-error correction using (255, 239) Reed-Solomon (RS) codes. The BMRx provides instantaneous (0 preamble bit) phase acquisition and a packet-...
