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

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%.
