· LAN to LAN Interconnect with Data Rate Governor ·

The LAN·GOV is used to interconnect Ethernet LANs through a data rate governor. The data rate governor utilizes Time Division Multiplexing based clocking to provide for Nx64, NxT1 and NxE1 bandwidth regulation that is configurable from 64 kilobits up to DS3.

Governing the WAN bandwidth utilized by an Ethernet LAN enables the reservation of WAN bandwidth for time sensitive real time connections such as those required by Video Conferencing, Voice Over IP and T1/E1 Over IP applications.

Wide Area Networks
Enterprises, Education, Government Agencies and Organizations are able to deploy LAN·GOVs to restrict network segments utilization of Wide Area Network Bandwidth. Governing a LAN segments Bandwidth is transparently implemented.

Service Providers
Unrestricted Ethernet connections provided by networking service providers enable subscribers to overburden the Service Providers network. The LAN·GOV enables service providers to limit a subscriber to a commited infomation rate.

Wireless Ethernet
Bridged connection such as those implemented in Wireless Ethernet bridges typically do not implement a method to ensure that the real time connections have priority. The LAN·GOV provides a straight forward method to ensure real time data delivery.

Governing Data Rate Versus Quality of Service
    Governing general traffic bandwidth is straight forward and easy to implement. Data rate configuration is all that is required.
    Quality of service in complex networks is cumbersome. Access to routers or switches in the link that are maintained by service providers or different organizations within an enterprise are difficult at best. Maximum Transfer Unit configuration may be required at low performance WAN connections for QOS.

Transparent Interconnect
The LAN·GOV transparently monitors all the packet traffic on each of its LAN segments to determine whether the packets it receives are to be forwarded. The Ethernet MAC layer source addresses that are active on each LAN are stored in a filtering database. Packets with a MAC destination that do not match a MAC address entry for the receiving port are forwarded.

Ease of installation
To be operational the LAN·GOV requires the configuration of the data rate. Configuration is performed through a Command Line Interface that is accessed through a console port or with Telnet.
