What is DOCSIS QoS?
The DOCSIS protocol is used to support quality of service for traffic between the cable modem and the CMTS device. To support QoS, the DOCSIS protocol uses the concept of service flows for traffic that is transmitted between cable modems and CMTS devices. You can supplement best effort with QoS parameters.
What does DOCSIS mean?
Data Over Cable Services Interface Specification
DOCSIS stands for Data Over Cable Services Interface Specification. Since that’s a mouthful, we prefer saying “dok-sis”. Basically, DOCSIS is an international telecommunications standard that lets cable television operators add high-speed and telephony data to their current cable TV systems.
What does DOCSIS compliant mean?
Data Over Cable Service Interface Specifications
Data Over Cable Service Interface Specifications (abbreviated as DOCSIS) is a globally-recognized telecommunications standard that enables high-bandwidth data transfer via existing coaxial cable systems that were originally used in the transmission of cable television program signals (CATVS).
What is DOCSIS 3.0 channel bonding?
DOCSIS 3.0 Downstream Bonding enables high-speed broadband access and helps cable operators offer more bandwidth-intensive services by adding one or more additional downstream quadrature amplitude modulation (QAM) channels to the standard broadband DOCSIS system.
What is DOCSIS 3.1 advanced technology?
DOCSIS 3.1 is faster than DOCSIS 3.0, because of the advanced signal process techniques. The advanced techniques use a frequency spectrum and increases the available spectrum for transferring downstream and upstream data. It works by using a higher-order modulation to transfer data, which is more efficient.
What is GPON and DOCSIS?
Today, DOCSIS 3.1 (10 Gbps/2 Gbps) may offer more than GPON (2.5 Gbps/1.25 Gbps) – but fibre infrastructure can be reused for XG/NG-PON, with better capacity than DOCSIS 3.1. The reason is the necessity of DOCSIS 3.1’s continuous investment in additional channels to keep up with growing traffic consumption.
What is DOCSIS 3.0 modem?
DOCSIS 3.0 enables modems to combine multiple channels to stream data, increasing the speed of both downloads and uploads. For example, 8×4 modems—that is, modems with eight downstream channels and four upstream channels—support a theoretical maximum of 343Mbps.
What does 8×4 channel bonding mean?
Bonded channels are written as ‘Number of Downstream channels X Number of Upstream channels’. So, an 8×4 modem would have 8 downstream channels and 4 upstream channels. For example, a 16×4 modem can reach speeds of (16×38 Mbps = 608 Mbps) downlink and (4×27 Mbps = 108 Mbps) uplink throughput.
Will DOCSIS 3.1 make my Internet faster?
DOCSIS 3.1 provides faster Internet speeds using advanced signal processing techniques that increase the available spectrum for transferring downstream and upstream data. This process transmits more data traffic, faster and more efficiently.
