Motorola DOCSIS® 3.0 & Channel Bonding Introduction Joshua Eum Director of Solutions Sales June 13, 2006 Today’s Agenda • • • • Channel Bonding Introduction M-CMTS Introduction DOCSIS 3.0 Update Motorola Summary Subscriber Bandwidth Escalation Continues • • Voice, Video, Gaming and Data Services are Driving new and higher bandwidth Requirements – Customers are requiring greater Capacity – Competition is Fierce • DSL is providing much higher bandwidth – ex. 50 Mbps with VDSL/ADSL2 • Some Telco’s deploying higher bandwidth via Fiber-to-theHome/Curb • Satellite going to 1000+ Channels – Some Customers are even requiring more Bandwidth then a single Downstream or Upstream can deliver; higher rate limits Cable Operators need a Higher Bandwidth Downstream & Upstream Solution! DOCSIS Evolution: Higher Bandwidth with each Successive Version DOCSIS 1.0/1.1: • Higher Upstream (US) and Downstream (DS) Speeds & Greater Density lead to additional services & Lower Subscribers per DS/US DOCSIS 2.0: • • Additional Bandwidth in US Only: ATDMA, SCDMA, Logical Channels Ingress Noise Cancellation created Additional Bandwidth in US only DOCSIS 3.0: • Bonding together Downstream & Upstream Channels to create higher bandwidth Logical Channels • Draft Specification within CableLabs® Standards Group • Downstream definition happening with M-CMTS Edge QAM effort • Downstream works with some existing CMTS Hardware • Requires new CM Hardware Higher Bandwidth via Channel Bonding • Increasing Bandwidth by transmitting DOCSIS frames across multiple RF Channels • Standards effort for both Upstream (US) and Downstream (DS) direction • Standard will logically bond together some number of US or DS RF Channels and then multiplex packet transmission over those RF channels Bonded RF Channels Current DOCSIS Downstream Bandwidth Downstream IP Packets from Internet CMTS Independent Downstream Channels CM DOCSIS Downstream Bandwidth with Channel Bonding Downstream IP Packets from Internet CMTS Bonded Downstream Channels CM M-CMTS Network Diagram CMTS Core DCs Upstream Edge MPEG Server NSI Regional Area Network C M T S HFC 2.0 CMs DEPI CIN GBE Switch M-CMTS: Modular CMTS DTI: DOCSIS Timing Interface DEPI: Downstream External Phy I/F GBE: Gigabit Ethernet EQAM: Edge QAM ERMI: Edge Resource Mgr I/F DC: Downstream Channel CIN: Converged Interconnect Network DTI DRFI DEPI DEPI EQAM T-MPT MPEG EQAM ERMI Edge Resource Manager STB 3.0 CMs M-CMTS Goals • “Independent scalability of CMTS functions from DS PHY” – Means: need to add DS channels without adding US channels • “Lower the cost to deliver video over DOCSIS service to be competitive with today’s MPEG VOD” – 2005 Incremental DOCSIS DS channel cost: $24K ASP for 2DS+8US CMTS blade = $12, 000 per DS channel – 2005 Incremental MPEG VOD channel cost: $12K for 24-channel MPEG EQAM = $500 per DS channel • But with no rate limiting, scheduling, QOS, encryption, VOIP compression, or RF switching What’s important and not for M-CMTS • What’s important is that the two M-CMTS goals be met: – De-coupling downstream and upstream capacity; and – Lowering the cost of downstream capacity. • What’s important is the adoption of the DEPI specification by the EQAM industry. – Enables a transition to DOCSIS IPTV with DEPI EQAMs. • What’s NOT important is the concept of separating the upstream PHY layer: – Separation into an “upstream shelf” and definition of an “Upstream Edge Physical Interface” (UEPI) – Independent vendor implementations of “CMTS Core” and “upstream shelf” MAC functions DOCSIS 3.0 Features • Channel Bonding – – • • – IPv6 Provisioning & Management of CMs – Alternative Provisioning Mode & Dual-stack Management Modes for CMs – IPv6 Connectivity for CPEs Upstream Channel Bonding Downstream Channel Bonding IP Multicast – Source Specific Multicast – QoS Support for Multicast • Security – Enhanced Traffic Encryption – Enhanced Provisioning Security – Certificate Revocation • Network Management – CM Diagnostic Log – Enhanced Signal Quality Monitoring – Service Statistics Reporting IPv6 • Physical Layer – Upstream Frequency Range Extension • Business Services over DOCSIS – Layer 2 Virtual Private Networks – Support for T1/E1 Services Motorola: M-CMTS/D3.0 Leadership • Motorola driving M-CMTS & DOCSIS 3.0 Standards: Channel Bonding, DRFI with Mike Patrick, Jack Moran • Motorola Acquires Broadband Innovations for High-density, Low-Power RF and DOCSIS 3.0 DRFI Compliance • Motorola partners with Juniper for M-CMTS Core Module and to bind together DOCSIS & IP Services • Motorola demonstrates highest performing Channel Bonding:140 Mbps over 4 channels solution at CES Show – January 2005 • Motorola Partners with rgb Networks to bring its customers leading M-CMTS Edge QAM • Motorola working closely with Broadcom for advanced MAC & Phy Solutions Summary • Customers are requiring greater Capacity • Competition is Fierce • Some Customers are even requiring more Bandwidth then a single Downstream or Upstream can deliver; higher rate limits • Cable Operators need a Higher Bandwidth Downstream & Upstream Solution! • DOCSIS 3.0 & Channel Bonding provide this solution • Motorola is delivering on these capabilities Today!
