Distributed Switching on DGS-8000
•
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
•
It is stated that Sup720 has 720G switching bandwidth which is
calculated as the following algorithm:
•
18×20G×2＝720Gbps
switching
channels
•
•
Catalyst6500 series
•
full duplex switching
bandwidth per channel
Bidirectional
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.
Competitive Comparison & Analysis
CISCO-6500: Switching capacity calculation - chassis
C6513 switching capacity: 40G1 * 2 * 5 + 20G2 * 2 * 7 + = 680Gbps2
C6509 switching capacity: 40G1 * 2 * 8 = 640Gbps
C6506 switching capacity: 40G1 * 2 * 5 = 400Gbps
C6504 switching capacity: 40G1 * 2 * 3 = 240Gbps
Sup720 provides unidirectional 40G (dual 20Gbps)
per slot
C6503 switching capacity: 40G1 * 2 * 2 = 160Gbps
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)

Note2: 2-8 slots only have single channel on C6513
Competitive Comparison & Analysis
Analysis: CISCO-6500 throughput - chassis
Why does not C6500 propagate throughput to the whole 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!
The real throughput is not as claimed 400Mpps

Analysis: CISCO-6500 throughput – line card
Why does not C6500 propagate line rate ability
 X65xx line card, with DFC3 daughter card, throughput is 15Mpps

• Support up to 10 GE ports at line rate
• None of X65xx GE line cards is line rate
 X67xx line card, with DFC3 daughter card, throughput is 48Mpps
(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
 X68xx line card, with DFC3 daughter card, throughput is 24Mpps
(equals to 17.9Gbps unidirectional)
• Support up to 16 GE ports at line rate

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, WS67xx 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.
Competitive Comparison & Analysis
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.

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.
