SPEEDLAN Installation and Operation User Guide
Introduction 1-3
IP Routing with Advanced Filtering for Security
The SPEEDLAN brouters support IP Routing in addition to bridging. It can be used to add routing
capability when an IP router may be a more appropriate choice.
SNMP Management
SNMP wireless and wired link management may be administered from any Ethernet network or
remotely from the Internet. The SNMP MIB II, Bridge MIB, and Ethernet-Interface MIB come with the
brouters, so you can use SNMP to monitor a number of SPEEDLAN parameters, including RF-signal
quality and noise level.
Wireless Multipoint Protocol
Campus Cell PRC features provide multipoint networking, improved performance, and increased
reliability. In multipoint networks, a SPEEDLAN base station acts as a central base station with
responsibility to manage the flow of data within the radio cell. When necessary, packets are repeated
or retransmitted by this brouter, allowing communications between multiple remote networks by
using SPEEDLAN CPE.
ISP Functionality
The SPEEDLAN shelfmount ISP products are tailored to fit the needs of Internet Service Providers and
Broadband Telecommunications Providers. Two features particularly useful to Internet Service
providers are the additional of Network Address Translation (NAT) and Dynamic Host Server
Protocol (DHCP). NAT helps to ensure network security and allows an entire company to share a
single global IP address for communication on the Internet. For example, a company can provide its
clients with just one IP address, allowing access to the company’s firewall only. DHCP servers
provide efficient use of IP addresses by assigning them dynamically or statically to the wireless
brouter location. DHCP allows network administrators to assign dynamic IP addresses for the period
of time needed to connect to the Internet or network, whereas static IP addresses are beneficial to
users that need to maintain a "constant" connection. This reduces the load on the entire wireless
network.
