Factors Driving the Evolution to Gigabit Ethernet—Traffic Increase

• Traffic increased by a factor of 400 between 1990 and 1998

• Next 5-year growth is expected to be by a factor of 1000

• All PCs and servers will ship with 10/100/1000 BaseT network cards by 2003

• Migration from distributed storage to centralized storage

• Ethernet connected devices will grow exponentially (alarms, badge readers, security cameras, monitors, etc.) creating a need for more bandwidth

• Natural migration of core network technologies to the edge of the network


Factors Driving the Evolution to Gigabit Ethernet—Applications

• Storage and system backups

• Software distribution

• Database applications (such as ERP and CRM)

• Science, education, manufacturing, entertainment

S2

• CAD/CAM

• Video

• Surveillance

• Applications requiring low latency

• Large graphics files


Gigabit Ethernet with Intelligent Switching Is Crucial for Success

• Higher bandwidth alone does not solve the problem. Layer 2 switches are limited to the processing and forwarding of Layer 2 information only

• Multilayer switches can look deeper into the frame => intelligent decisions are based on detailed Layer 3 or Layer 4 information

• Why this is useful:– Prevents bottlenecks caused by higher bandwidth by using intelligent routing

and allows you to use existing infrastructure to the core

– Adds an intelligent layer of security to the network that results in lower hardware operations costs and information loss

– Increases the network quality of service, which enables the deployment of lower-cost, IP-based services and applications (IP telephony, video on demand, application distribution servers, etc.)

– Increases network availability by monitoring routes and dynamically routing around network outages or providing least cost routing

GTTD by the Numbers - ROI

* Catalyst 3750G-24TS is ~$142 list price premium per access port relative to 3550-24

** Due solely to the 1000% increase in network speed that Gigabit provides over Fast Ethernet

*** $30/hr equates to a salary of about $53,000 + 15% overhead for benefits

Models based on ability to increase network access from 100 Mbps to 200Mbps (achievable on any current PC)Model 1 – heavy network user, accesses most data from serversModel 2 – light user, only accesses data from network occasionally

Identity-Based Network Services

What it does:

Using the 802.1x protocol with Cisco enhancements, the network grants privileges based on user logon information, regardless of a user’s location or device

Benefits:

Allows different people to use the same PC and have different capabilities

Helps users get only their designated privileges, no matter how they are logged onto the network

Reports unauthorized access
