Features and Benefits
IP Routing with Advanced Filtering for Security
The SPEEDLAN TM supports IP Routing in addition to bridging. It can be used to add routing capability when an
IP router may be a more appropriate choice.
Transparent Ethernet Bridging with Advanced Filtering for Security and Network Reliability
SPEEDLAN TM supports what is known as Transparent Ethernet Bridging with no Spanning Tree or Source
Routing support. Since the brouter contained in the SPEEDLAN TM is intended to provide network security
between a local LAN and a campus or enterprise wide network, and since using multiple bridges in a Spanning
Tree could compromise this security, the Spanning Tree scenario is not supported. In addition to the Transparent
Ethernet Bridging, the SPEEDLAN TM can drop (i.e., not forward) packets based upon the encapsulated higher
layer data within the packet. It is this option that gives SPEEDLAN TM the ability to perform advanced firewall
filtering and can add a significant measure of security and network reliablility to a network, surpassing that
provided by modern multiprotocol routers.
