120 Mbps upstream? Even 30 Mbps? Come on- who really needs it?: Note: I've amended this post with corrective information, including this from our networking guru, George Ou. George,an actual engineer, points out: You cannot claim DOCSIS 3.0 is 160/120 down/up service and compare it to 50/30 down/up FiOS service. That is grossly misleading. 160/120 down/up in...; Tags: Wavelength, DOCSIS, Mbps, Home, FiOS, Cable, Broadband Internet, Corporate Communications, Telecommunications, Personal Technology, Marketing, Russell Shaw; Blog posts 2007-12-03
EFF wants to saddle you with metered Internet service: Updated 12/8/2007 - The EFF Electronic Frontier Foundation last week publicly joined Free Press and Public Knowledge in recommending a metered Internet service as the alternative to Comcast's BitTorrent throttling. The extremist "Net Neutrality" crowd that wants to regulate the Internet with bans on per-user charges/contracts for Enhanced QoS are...; Tags: Electronic Frontier Foundation, BitTorrent, Network, Comcast Corp., Problem, Internet Service Provider, DOCSIS, Internet Service, ACL, Internet Service Providers (ISPs), Networking, Cable, Broadband Internet, Internet, Telecommunications, Personal Technology, George Ou; Blog posts 2007-12-03
Migrating Simple Data Over Cable Services to DOCSIS 1.1: The Data-Over-Cable Service Interface Specifications DOCSIS 1.1 standard gives cable service providers the opportunity to deploy a whole new suite of sophisticated multimedia and real-time services. Before these services can be deployed, it is important that current data services are able to be migrated from a DOCSIS 1.0 operating environment...; Tags: DOCSIS, Cable, Broadband Internet, Telecommunications, Personal Technology; White papers 2007-08-03

FIOS, DOCSIS 3.0: The future's so fast you gotta wear goggles: Businessweek's Arik Hesseldahl writes today about the upcoming growth in consumer bandwidth, already available to some through Verizon's $180-a-month 30 Mbps/5Mbps FIOS service. Comcast and other cable carriers are testing DOCSIS 3.0 technology, a data-over-cable system, that can deliver 150 Mbps download speeds, though there is no schedule for commercial...; Tags: Business &, Technology; Blog posts 2007-05-29
Advanced PHY Layer Technologies for High Speed Data Over Cable: This paper highlights the major differences between DOCSIS 2.0 and earlier versions, and discusses advantages of deploying the advanced PHY technology available nowadays.

Unleashing the Speed With DOCSIS 2.0: Supporting the Burgeoning Commercial Market: Originally, most Internet content was DownStream DS related and required an asymmetrical design of DS speed versus UpStream US speed. Most traffic was web-based downloads and e-mails, and very bursty in nature. Streaming content was added that caused average usage to increase. Peer-to-Peer (P2P) traffic created more US and DS...; Tags: DOCSIS, Speed, Cable, Broadband Internet, Peer To Peer (P2P), Telecommunications, Personal Technology, Internet; White papers 2006-06-13
Experimental Evaluation of FAST TCP Performance and Fairness in DOCSIS Cable Modem Networks: This paper presents experimental results evaluating the performance and fairness of FAST TCP in a series of tests involving realistic low rate network access scenarios.

Making Business Sense Out of the Wideband Protocol for a DOCSIS Network: To date, cable operators have enjoyed an upper hand in the competition to deliver highspeed services because of their network capacity and bundling strategy. In the U.S., telcos' attempts to counter this advantage by reliance on Digital Subscriber Line DSL service have been somewhat successful in attracting new subs. But...; Tags: Cable Company, DOCSIS, Cisco Systems Inc., Service, DSL, Network Technology, Cable, Broadband Internet, Ethernet, Networking, Telecommunications, Personal Technology; White papers 2005-11-17
Upstream FEC Errors and SNR as Ways to Ensure Data Quality and Throughput: To operate a High Speed Data HSD network over a Hybrid Fiber/Coaxial HFC cable plant requires a significant level of quality control to ensure data integrity and the highest level of data throughput.
