Question

Answer

 

 

What is DynamicAccess® software?

DynamicAccess software brings intelligence

 

to the end systems to provide improved

 

network performance and control. You can

 

download the latest DynamicAccess

 

software from the 3Com Web site:

 

www.3com.com.

 

 

What is Fast IP?

Fast IP is software that improves

 

performance on switched networks. Fast IP

 

allows end systems (notebooks and servers)

 

to discover switched communication paths.

 

By creating switched short cuts, Fast IP

 

allows end stations to bypass the router

 

and transfer data across wire-speed

 

switched paths. Fast IP is part of 3Com’s

 

DynamicAccess software.

 

 

What are the notebook and

Client requirements:

network requirements to run

Notebook running Windows 95, Windows

Fast IP?

NT (versions 4 or 3.51), 3Com Megahertz

 

 

10/100 LAN CardBus PC Card, and the

 

TCP/IP stack.

 

Network requirements:

 

Switched path between stations and single

 

broadcast domain.

 

 

What are the network configuration

Fast IP is designed to bypass the router,

requirements for Fast IP?

particularly where the router is a

 

bottleneck, as well as to leverage the

 

switched infrastructure. For Fast IP to

 

create short cuts around routers, there

 

must be a switched path between source

 

and destination.

What is the performance gain when using Fast IP?

Fast IP bypasses the router to provide increased performance in switched networks even if there are just a small number of network nodes using Fast IP. The performance gain obtained when deploying Fast IP is directly related to traffic load on the backbone router. The more traffic is pumped to it, the bigger the latency and response time and the higher the performance gain. Internal tests show performance increases in the order of 600% when routers are loaded at 70

to 75%.
