  2. Switching card supports the following options: 10/100 Base T 10100 Base Fx 1000 Base SX 1000 Base LX Supports auto negotiation Supports Flow control Supports Jumbo frames (up to 9216 bytes) Supports MDI-X 10/100 Base Ethernet ports can be configured in Full or Half duplex mode. 1000 Base Ethernet ports in Full Duplex mode Ethernet ports Features

  3. Line rate switching Supports 4K VLAN per port VLAN Stacking (Q-in-Q) is supported on all the GbE ports Per port rate limiting at 64 kbps granularity is supported on all the client ports Switch has a built-in packet classification and filtering engine that gives it the following capabilities Layer 2-Layer 4 packet classification and filtering Policing of flows based on programmable token bucket meters Actions (e.g. dropping, setting lower priorities) on packets that are not in conformance of programmed traffic profiles Remarking of priorities (e.g.IP v6 DSCP, 802.1p) based on filter match Traffic shaping using 1-8 CoS queues with strict priority, weighted round-robin, weighted fair queuing in scheduling Switching module : Salient Features

  4. Ethernet switching is based on Destination MAC address + VLAN- ID Shared L2 address table Supports up to 16K entries Entries can be configured aging or static Shared Multicast Table with 256 entries Allows disabling of MAC learning on a per port basis VLAN Ids can be configured Port based Protocol based Supports VLAN tagging and classification (IEEE 802.1 Q) VLAN stacking (Q in Q) Spanning Tree Protocol (IEEE 802.1 D) Rapid Spanning Tree Protocol (IEEE 802.1 w) MSTP (IEEE 802.1 s) Link aggregation (802.3ad) MAC and VLAN Switching

  5. Rate of each port can be configured with granularity of 64 Kbps For FE: 64 Kbps to 10/100 Mbps For GbE: 64 Kbps to 1000 Mbps Non conforming traffic can be dropped/back-pressured using PAUSE/RESUME thresholds. QoS Features • Flow Classification based on • VLAN ID • IP ToS • IP DSCP • CoS • Source/Destination MAC address • EtherType • Source/Destination IP Address • Source/Destination L4 address • Protocol field • Range of VLAN

  6. Police simple Rate limit the flow to meet committed information rate (CIR) Burst size restricted to committed burst size (CBS). Police Single-rate Rate limit the flow to meet committed information rate (CIR) Coloring based on committed burst size (CBS) and excess burst size (EBS) Police Two-rate Rate limit the flow to meet committed information rate (CIR) and Excess information rate (EIR). Coloring based on committed burst size (CBS) and excess burst size (CBS). Policing

  7. Supports 1- 8 CoS queues Supports following scheduling scheme Strict priority (SP) Weighted round robin (WRR) Weighted Fair queuing (WFQ) Combination of (WFQ or WRR) and strict priority. Traffic shaping to restrict bandwidth usage per CoS queue to minimum (BMIN) or maximum (BMAX) configurable bandwidth. HOL is avoided by dropping traffic after a configurable threshold is exceeded Supports WRED to avoid congestion Egress CoS queues

  8. Help operators provide New Revenue generating Broadband services By providing Integration with existing networks Network Predictability (Resilience of RPR and SDH) Single Network Management Best-in-class scalability Broadband

  9. Triple Play Services to residential subscribers High Speed Internet Access, Video-on-demand, IP-TV, Voice Quadruple play with Wireless Broadband Connectivity services to business subscribers Leased Lines/Transparent LAN Services VPN Services Evolution of Broadband Services

  10. Access Control Lists: allows the traffic to be permitted or denied based on: VLAN ID IP ToS IP DSCP CoS Source/Destination MAC address EtherType Source/Destination IP Address Source/Destination L4 address Protocol field Security Related Features • Broadcast Storm control • Can be enabled/disabled on a per-port basis • Port mirroring • Allows mapping of all incoming and outgoing packets on any specified port to a “probe” port • Performance Monitoring • The traffic statistics parameters can be provided every 15 mins and on daily basis • Parameters are monitored per flow and per port basis • Allows loop-back on a per port basis • Supports connectivity fault management as per 802.1ag

  14. Insert SPVLAN 3 Insert SPVLAN 3 Ethernet Leased lines LAN Metro Core P-to-p connection is set using Q-in-Q and n x VC-12/3 backhaul with requisite CIR & EIR and 8 levels of CoS. Customer LAN switch is connected to ELAN card at the two locations shown in figure LAN Customer Premises

  15. Ethernet Virtual Private Lines SDH Network VCG cap = 1 VC3 Customer-1,Site B Customer-1Site A Customer-2 Site A Customer-2,Site B Q-in-Q provisioned to segregate customers Video traffic is policed/shaped to 4 Mbps and BE traffic to 2 Mbps Higher priority is assigned to video traffic EVPL connection between two different sites of the two different customers with 6 Mbps backhaul carrying Video (VLAN ID = 1) and best effort (BE) (VLAN ID =2) traffic

  16. Ethernet Private LAN Site A Site C VCG cap = 2 VC4 Site B Site D 2 VC-4 worth bandwidth are allocated between two neighboring nodes After learning the traffic from any site to any other site is a unicast as shown EPLAN connection between customer offices spread across 4 sites Broadcast all destination look-up failure (DLF) traffic. Each node learns the MAC address of all the customer sites
