2 Agenda Existing Service offerings and equipment requirements The MSAN concept Service Transport Business Application example EFM Ethernet in the First Mile EFM and QoS

3 Today s Services Business Services Residential Services D SL AM Data Services Spli PBX Broadband tter DL C ADM Leased Lines Today s service offerings : ADSL2+, POTS, ISDN BRI, ISDN PRI, E1, E3/DS3 Required Equipment: DSL Mux, DLC, Splitter, SDH ADM POTS

4 The MSAN Concept Business Services Residential Services Broadband High Capacity Data VoIP/ POTS PBX / VoIP Private Networks Today s service offerings : ADSL2+, VDSL2, SHDSL, SHDSL.bis-EFM, POTS, ISDN BRI, ISDN PRI, E1-EFM, E3/DS3 Required Equipment: MSAN, Splitter (ISDN only) IPTV

6 Service Transport (RPR, EAPS) Softswitch Resilient Transport using standardized protocols IP Video Headend IP TV Active Ethernet VoIP EFM E1 (TDM) E1 CES PON ADSL2+ ISDN IPTV RPR/ EAPS VDSL2 POTS IPTV Ethernet/IP

7 Business Services Connecting Customers E3/DS3 34/45Mb 8.192Mb Multiple access technologies for all requirements Copper: SHDSL 1 through 8 x 5.7Mbps Ethernet transport E1: 1 through 8 x 2.048Mbps E3/DS3: 1 or 2 x 34/45Mbps Active Ethernet: 10/100/1000 Enet via SFP modules SDH 2.048Mb IP E1 - Data 10/100/1000 Base x Copper/fiber 22.8Mb 5.7Mb SHDSL - EFM Active Ethernet - EFM

8 E-LAN Application The Problem A Flexible set of connection speeds are required to serve the different needs for Headquarter, Remote Office and Teleworkers and preserve the ability to grow with easy and non-service affecting upgrades The WAN network needs to provide a secure ethernet transport and needs to transport the internal IEEE802.1Q structure Cost effective access connections require QoS Company wide LAN and VoIP Network Sw itch P BX Headquarter LAN Voice Remote Office The Solution Use EFM for efficient data transport Less overhead than ATM Less latency than ATM Private LAN Data Teleworker VoIP Provide bandwidth of up to 1000 Mbps using: EFM SHDSL EFM E1 EFM E3/T3 EFM Active Ethernet Transparent VLAN transport by using QinQ Prioritize VoIP traffic or business critical applications

9 EFM What s it anyway? EFM stands for Ethernet in the First Mile It is an IEEE standard (802.3ah) which defines Copper bonding Optical specifications OAM functions EFM works on any physical interface including Interfaces defined per IEEE802.3ah: G.SHDSL (PMD type 2Base-TL) VDSL2 (PMD type 10PASS-TS) PON (PMD types 1000Base-PX10/20) Active Ethernet (PMD types 100Base-LX10/BX10, 1000Base-LX10/BX10) Interfaces not yet defined per IEEE802.3ah E1/T1 (PMD not yet specified in the standard) E3/DS3 (PMD not yet specified in the standard)

10 Why EFM? Less latency than ATM-based products 64/65 byte encapsulation instead of SAR Higher throughput ATM may have a 10-30% atm related overhead dependend on the QoS requirements PTTs/Incumbants restrict the use of SHDSL.bis therefore it is important to gain highest throughput efficiency

11 Moving to Ethernet: What About QoS? Problem: - ATM was needed to separate traffic and apply QoS - EFM makes no special provisions for QoS Solution: - Zhone s MTM provides ATM-like QoS without PVCs Voice Traffic uses only a little bit of bandwidth, but requires a high priority 1 PVC for VoIP Video traffic needs a dedicated Bit Rate of ~3Mbps per channel 1 PVC for Video Data Services or other Bursty traffic types can use what s left over, or can be rate limited into Service Tiers 1 PVC for Data Voice Traffic uses only a little bit of bandwidth, but requires a high priority No PVCs! Video traffic needs a dedicated Bit Rate of ~3Mbps per channel The Separation of Services is done logically, in real time, by MTM Data Services or other Bursty traffic types can use what s left over, or can be rate limited into Service Tiers

12 Moving to EFM: What About QoS? MTM provides service separation and QoS without VCs Onsite Technician Voice Multicast Video VOD STB / Middleware OAM / Network Mngmt Gaming Web Browsing Business VPN Set-Top Box LAN

13 MTM Multimedia Traffic Management Define the transmission quality based on the service and its requirements 1. Classify the traffic Check on MAC-address/range, IP-address/range. VLAN, TCP/UDP port 2. Apply an action Set VLAN and L2 quality Set backbone VLAN ID for QinQ Define rate limits per traffic flow

14 Resume Traditional access network deployments require lots of equipment resulting in high initial and operational cost Multi-Service Access Nodes combine multiple technologies in a single device New technologies like EFM provide competitive advantages against traditional service providers or PTTs Intelligent OAM and traffic stearing implementations reduce truck-rolls and make services more cost-effective
