  8. Target ApplicationsEnterprise Access/Aggregation • ECMP & PBR provides redundant/load sharing capability of uplink. • IMPB, ARP Spoofing Prevention, DHCP Server Screening, BPDU Attack Protection, and L3 Control Packet Filtering expel threats out of core networks. • MAC, WAC, and Compound authentication provide clientless/easy-to-deploy mechanisms to authenticate users and devices. • Embedded DHCP server, auto-configuration, and trap/e-mail alerts make the network management much easier. Data Center DES-3810 DES-3810 Stack

  9. Target ApplicationsTelecom Access of Enterprises • ETTB CPE for business subscribers • Up to 4 GE FTTB interfaces providing higher bandwidth to customers and fault tolerance capability • Provides L2 transparency to customers through the ISP network • Y.1731, 802.1ag/3ah Ethernet OAMimproves the efficiency of ISPnetwork management VPWS Tunnel GVRP DES-3810 STP VLAN Branch VPWS ISP MPLS Core Tunnel DES-3810 DES-3810 GVRP STP VLAN GVRP QinQ & L2PT STP VLAN Branch HQ

Target Applications Enterprise Routers for Remote Sites • Larger routing table provides the capability for a large-scale enterprise • Border Gateway Protocol (BGP) allows central routing management of all remote sites regardless of physical connections DES-3810 RIP OSPF VPN BGP CPE Branch VPN VPN Internet CPE CPE BGP DES-3810 BGP RIP OSPF DES-3810 RIP OSPF Branch HQ

  11. Agenda Product Introduction Positioning Overview Product Overview Target Market Competitive Comparison & Analysis Positioning Highlight Key Comparison Art of the War Technology Briefing

  12. Technology BriefingEthernet Ring Protection Switching (ERPS) • First industry standard (ITU-T G.8032) on Ethernet ring protection switching • Support interconnected ring or multiple rings application • Best case: 50ms recovery time for 16-node ring with <1,200 Km circumference Link Down! Aggregation Ring Access Ring Master Master Disable Blocking Link Down!

  13. Technology BriefingBandwidth Control & Three Color Marker • Single user/service per port, with bandwidth limit (Port Bandwidth Control) • Multiple users/services per port, with bandwidth limit (Flow-based Bandwidth Control) • Multiple users/services per port, with bandwidth limit and guaranteed bandwidth (Three Color Marker & Policing) • Two Rate Three Color Market & Policing • Committed Information Rate (CIR): Guarantees the bandwidth of each service by limiting the bandwidth of each other. • Peak Information Rate (PIR): Allows services to takethe unused bandwidth for better bandwidth usage. • Traffic Policing: Drops or remarks the packetpriority tag for traffic exceeding CIR. Doing best-effort forwarding when peak of eachservice are conflicted. IPTV CIR VoIP CIR PIR PIR PIR Data CIR Total UNI (User Network Interface) Bandwidth

  14. To lower the packet lose rate, almost all switch controllers have built-in expensive buffer memory to prevent the data re-transmission. Switch stores the traffic in buffer memory and delays the transmission until the egress bandwidth is available. However, the best-effort traffic shaping is no longer enough for the QoS requirement nowadays. Technology BriefingTraffic Shaping Buffer Memory bps bps Store to buffer Max. Switching Capacity Time Time Data Data Delay Forwarding Delay Forwarding

  15. To well manage the buffer resource, DES-3810 supports some advanced features: Reserve buffer memory for importantservices Configurable buffer size for each important service - Excess Burst Size (EBS) - Peak Burst Size (PBS) - Committed Burst Size (CBS) Technology BriefingTraffic Shaping (Continue) Drop No reservation for Data exceeding PIR PIR/EIR CBS for Data Buffer Memory EBS for IPTV bps CIR Store to PBS/EBS Store to PBS/EBS Max. Switching Capacity Data Store to CBS Store to CBS PIR/EIR Time Guaranteed Forwarding Guaranteed Forwarding Overall Output CIR Delay Forwarding Delay Forwarding CBS for IPTV IPTV

  16. WRR DRR/ WFQ WRR Smoothed Round-robin Technology BriefingSmoothed Deficit Weighted Round Robin (SDWRR) • Accurate and fair scheduling is required to make the egress bandwidth usage more proper nowadays • Fair Queue (FQ), WFQ, Deficit Round Robin (DRR), WDRR: Forward/scheduling decision made by byte count and utilization of queues, the true weight of each queue. • Smoothed round-robin mechanism makes rapid passes for each queue and use more turns for high queues instead of waiting all packets transmitted in high queues. Second Round First Round

  17. Compatible with existing MPLS network, using LDP for label switching Transparency of subscriber’s L3 routing protocol in ISP network, reduces the effort of ISP and also provides better extensibility in subscriber networks Co-works with QinQ and L2PT to provide L2 transparency to customers Technology BriefingVirtual Private Wire Service (VPWS)

  18. Switch Resource Management templates allowuser optimizing the switch databases for different application. Routing Mode: For applications requires larger routing tables such as company gateway VPWS Mode: For applications requires lots of L2 VPN tunnels such as ISP access switch Technology BriefingSwitch Resource Management (SRM)

  21. Technology BriefingHost-based IGMP Snooping • Bandwidth of Ethernet allows multiple IPTV channels in the same time • Host-based IGMP Snooping is future proofing for IPTV service: • Multiple IPTV under a single port. Channel surfing of one IPTV does not effect others • Support fast leave for quick channel switch IGMP / PIM AggregationLayer Access Layer IGMP Snooping Legacy Device Host-based IGMP Snooping IP STB IP STB IP STB

  22. Technology Briefing DHCP Relay Option 60/61 • The DHCP options provide accurate IP manageability for network administrators • DHCP option 82: Assign IP based on circuit ID (client VLAN, port, or switch's MAC address) • DHCP option 60: Assign IP based on pre-defined string • DHCP option 61: Assign IP based on MAC address or pre-defined string ISP DHCP Server 1 IPTV Partner 1 Internet Relay to different DHCP server based on inserted MAC ISP DHCP Server 2 IPTV Partner 2 Insert MAC Insert MAC Relay to different DHCP server based on inserted string Inserta user-defined string Insertcustomized string IP STB 1 IP STB 2 IP STB 1 IP STB 1 IP STB 2 IP STB 2 Option 60 Option 82 Option 61

  23. Change pair, no need to change cable Usually multi-pair cables are used for the network construction of cabinets or buildings Detecting various of errors - Lines of specific pair is left open - Two lines of a pair is shorted - Lines of different pair are short - Cable does not exist or quality is too bad Locatingthe position of cable errors, saving time on cable repairNote Technology BriefingCable Diagnostics Note: DES-3810 supports distance check on GE port only
