On the Performance Modelling and Optimisation of DOCSIS HFC Networks
The DOCSIS protocol defines the MAC and physical layer operations governing two-way transmission of voice, video and multimedia data over HFC cable networks, thus constituting a complex system with many interdependent parameters. This tutorial employs simulation and analytic methodologies for the performance modelling and optimisation of DOCSIS 1.1/2.0 HFC networks with particular focus on the ...
متن کاملScheduling Delay Minimization for Non-UGS Data in Multi-Channel HFC Network
The multi-channel Hybrid Fiber Coaxial (HFC) network is essentially a shared medium with multi-channels. Its operation requires the use of a scheduling algorithm to manage the data transmission within each channel. The Data-Over-Cable Service Interface Specification (DOCSIS) protocol is an important standard for HFC networks. Since this protocol does not explicitly specify the scheduling algori...
متن کاملExperimental 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 کاملA Novel Mechanism for Contention Resolution in HFC Networks
The Medium Access Control (MAC) scheme proposed by DAVIC/DVB, IEEE 802.14 and DOCSIS for the upstream channel of Hybrid Fiber Coaxial (HFC) access networks is based on a mixable contention-based/contention-less time slot assignment. Contention-less slots are assigned by the head end to end stations according to a reservation scheme. Contentionbased slots are randomly accessed by active terminal...
متن کاملA Tutorial on DOCSIS: Protocol and Performance Models
Since the first community antenna television (CATV) system was deployed in 1948, cable technology has advanced at an astounding rate. Today, multiple service providers (MSOs) are competing with telephone companies to deliver the long sought ‘triple play’ of voice, video and data to residential and business premises. Upstream data rates have progressed from dial-up speeds to 10Mbps and to 100s o...
