• Dumb Line Card without capabilities to determine switching path• All traffics MUST be processed by “Control Card”• Switching performance relies on “Control Card”• Packets always be transmitted back and forth between Control Cards and Line Cards

• Intelligent Line Card with capability to determine switching path• Synchronized switch/route information on Control Card and Line Card • Layer 2/3/4 Local on board switching capability• Fastest forwarding, near zero-wait

Product Overview

• Distributed switching architecture– DGS-8000 consists of chassis, Control Modules, and I/O Modules.– Control Module and I/O Modules comprise

– ASIC for switching functions– CPU for management and module control

– Synchronized switch/route information on control modules and I/O modules.

– Switch/route information on I/O modules is periodically updated from the Control Module.

– L2/L3/L4 ACL/QoS intelligent switching on I/O modules– On-board crossbar fabric comes fastest switching performance.

CISCO-6500: Switching Capacity Calculation - engine

switching channels

full duplex switching bandwidth per channel

Bidirectional

• It is stated that Sup720 has 720G switching bandwidth which is

calculated as the following algorithm:

• 18×20G×2 ＝ 720Gbps

• Due to hardware architecture, one 20G channel is for internal use. Only 17 channels can be used by users.

• Currently, only three interface modules (WS-67xx) can fully make use of dual 20G fabric channel to 720G SFM.

• Abundant Interface modules (WS-65xx and WS68xx) are only one or two 8G channels to 720G SFM, such that utilization of bandwidth is very low.

Catalyst6500 series


CISCO-6500: Switching capacity calculation - chassis

C6513 switching capacity: 40G1 * 2 * 5 + 20G2 * 2 * 7 + = 680Gbps2

C6509 switching capacity: 40G1 * 2 * 8 = 640Gbps




Sup720 provides uni-directional 40G (dual 20Gbps) per slot

Competitive info:1.With dual engines, chassis switching capacity needs to minus 80Gbps (the engine occupies one more slot)

2. Switching capacity of engine (720G) Switching capacity of the chassis (listed above)

*Switching capacity of chassis means summation of all slots bandwidth


Note1: Bandwidth of WS-X67xx (dual channels)Note2: 2-8 slots only have single channel on C6513

Analysis: CISCO-6500 throughput - chassis

With SUP32, the whole chassis only reaches 15Mpps (equals to 20Gbps bi-directional,

10Gbps uni-directional):• Support up to 1G x 10 with line rate

• Support up to only 10G x 1 with line rate

• SUP32 is only suitable for Wiring Closet, or FE to desktop

Claimed SUP720 switching capacity (WS-SUP720 & WS-SUP720-3B): 400Mpps

Real SUP720 switching capacity (if with C6509): :• C6509 with one SUP720 and maximum 8 slots for service, also consider GE x 2 on

engine:

• 48Mpps * 8 + 1.4881Mpps * 2 = 387Mpps

• If dual engines are configured, the chassis throughput is: 342Mpps

• And above calculation is based on line cards with DFC3!

Why does not C6500 propagate throughput to the whole chassis


The real throughput is not as claimed 400Mpps

X65xx line card, with DFC3 daughter card, throughput is 15Mpps

(equals to 10Gbps uni-directional)• Support up to 10 GE ports at line rate

• None of X65xx GE line cards is line rate


(equals to 35.8Gbps unidirectional)• Support up to 32 GE ports at line rate; 48*GE or 4*10GE line card are not line rate,

• 24*GE line card (X6724) only have 17*GE line rate

• None of X67xx line cards is line rate


(equals to 17.9Gbps unidirectional)• Support up to 16 GE ports at line rate

• Only X6816 of X68xx can be line rate, the only line rate card of CISCO GE line cards

Why does not C6500 propagate line rate ability

Analysis: CISCO-6500 throughput – line card


Competition With Cisco Catalyst 6500

How to compete with Cisco 6500/6500E

Cisco 6500 Backplane design with 32G share bus increases possibility of single point of

failure

Cisco 6500 SUP32 can not work with C6513

Cisco 6500 SUP2 and 256G SFM occupy at least 2 slots in chassis, port density is not

competitive

Customers’ switching bandwidth is smaller than publicized 720G by Sup720

Cisco 6500 can offer up to 400Mpps throughput only in case of Supervisor Engine 720, WS-

67xx interface card, and DFC3 card

Cisco 6500 SUP720 can work with WS-65xx/68xx interface modules, but only one 8G or

dual 8G channels available, utilization of bandwidth is low

If classic 6500 interface module exists in SUP2 or SUP720 chassis, only 15Mpps throughput

Competition With HP ProCurve A7500

How to compete with HP chassis DGS-8000 can support up to 160G bandwidth per slot, but HP A7500 only supports up to

48G bandwidth per slot and has poor performance in the status below: Without Fabric Mod 768, HP A7510 can’t reach 1,152G bps and will have low

performance .

Ex: With one engine and Fabric Mode 384, A7503E/A7506E can support 24G channel per slot; but A7510E only supports 12G channel per slot)

HP A7503-S uses low cost chassis and supervisor engine (Only 12G channel per slot)

DGS-8000 Line cards support L2/L3/MPLS/VPLS/IPFIX/IPv4/IPv6 and up to 8x 10GE ports per line card*. But for HP A7500 line cards:

SA can’t support L3/MPLS forwarding SC can support L3 distributed forwarding but can’t support MPLS forwarding EA can support L3/MPLS distributed forwarding but can’t support IPv6 hardware

forwarding Only SD/EA/EB can compete with DGS-8000. But SD only has maximum 8-port 10GE

(1:2 blocking rate) and no MPLS support; EA only has 1-port 10GE and does not support IPv6; EB only has 4-port 10GE.


Competition With HP ProCurve A7500

How to compete with HP chassis DGS-8000 supports BFD for static route/OSPF/VRRP. But for HP A7500, only EB cards

support BFD

HP A7500 Fabric Mod 384 Lite can’t support L3 forwarding. Even using two fabric cards, it cannot run continuous forwarding when one fabric card crashes because the L3 table in line cards must be refreshed.

HP A7500 uses sFlow and Netstream for packet sampling. sFlow and Netstream has poor sampling performance. Netstream is not an international standard. DGS-8000 supports IPFIX which has better performance than sFlow. (When IPFIX is in use, suggest to adopt 8000-ASE-IPFIX)

DGS-8000 uses new DRR (Deficit Round Robin) for scheduling which can handle packets of variable size without knowing their mean size. HP A7500 only supports WRR (Weighted Round Robin) which can not differentiate the video, voice or data packets.

DGS-8000 has more competitive price then HP A7500, especially for A7510 with Fabric Mod 768 engine.

Drawback Highlights Although HP provide the low cost for pre-configured bundles. The total cost for HP

8212zl is still a little higher. (see next page) HP ProCurve E8200zl Series switches do not support some features for advanced

application, such as BGP, Policy-based routing, Ring Protection, DHCP Server etc. HP ProCurve E8200zl Series switches does not support dynamic IPv6 routing

Competition With HP ProCurve E8200zl

How to compete with HP ProCurve E8200 chassis

HP 8212zl series only provides 993.6Gbps switching capacity ; DGS-8006 series can

provide up to 1.28T bps .

HP 8200zl series only have 28.8Gbps from modules to backplane. It has high blocking

rate for 4-port 10G modules.

Many advanced features are missing like BGP Policy-based routing, Ring Protection,

DHCP Server etc.

You can easily spec HP chassis out in truly core application because its limited S/W

functions.

E8200zl is positioned in between D-Link DES-7200 & DGS-8000. For feature

competition, use DGS-8000. For price competition, use DES-7200.
