Experimental evaluation of DOCSIS 1.1 upstream performance
Data-Over-Cable Service Interface Specification (DOCSIS) is one of the many last mile technologies intended to provide Internet access and packet-based services to the customer. DOCSIS uses the widely deployed hybrid fiber/coax (HFC) network as the physical link between multiple cable modems (CMs) and the cable modem termination system (CMTS). This paper presents the upstream performance of DOC...
متن کاملImproved priority access, bandwidth allocation and traffic scheduling for DOCSIS cable networks
The Data Over Cable Service Interface Specifications (DOCSIS) is intended to support IP flows over HFC (Hybrid Fiber/Coax) networks with significantly higher data rates than analog modems and Integrated Service Digital Network (ISDN) links for high quality audio, video and interactive services. To support quality-of-service (QoS) for such applications, it is important for HFC networks to provid...
متن کاملArchitecting Green Broadband Cable Access Network: Energy-Delay Trade-off
We propose and investigate an energy-saving algorithm for DOCSIS-3.0 cable access networks. Numerical simulations indicate a possible 17.4% energy-saving for 8000 cable modems, but also reveal a fundamental trade-off between energy and delay. OCIS codes: (060.4250) Networks; (060.4256) Network optimization
متن کاملAdaptive scheduling in DOCSIS-based CATV networks
This paper studies the effect of the DOCSIS MAC layer on the performance of two-way TCP transfers in Hybrid Fiber Coax (HFC) networks. We propose a new adaptive scheduling scheme called Long Packet Deferment (LPD) at the headend to improve TCP performance in DOCSIS-based HFC networks. LPD reduces the frequency of transmission of long packets and, if such long packets are transmitted, they are s...
متن کاملExperimental Evaluation of FAST TCP Performance and Fairness in DOCSIS Cable Modem Networks
In this paper we present experimental results evaluating the performance and fairness of FAST TCP in a series of tests involving realistic low rate network access scenarios. Links both using the DOCSIS cable modem medium access control (MAC) cable modem and simple low rate links were investigated. We seek to compare our expectations from theory with the behavior of an actual access network impl...
