What is a Server Card?

The Server Card is a CPU built-in card for realizing seamless connection with existing LAN in an ATM network environment.

The card is mounted on ATM Switches, which serves as the core of an ATM network, to provide LANE server, ARP server, and NHRP server functions.

Following are features of the server card:

■Provides server functions conforming to various specifications

The software that provides the LAN emulation server functions is installed in the card with a built-in CPU to facilitate the construction of LAN emulation. By installing software with ARP server and NHRP server functions, it is possible to eliminate bandwidth waste caused by conventional broadcast address solution and improve the capacity of the network as a whole.

■Hot-Swappable

The server card can be inserted into or removed from the ATM switching system without affecting its switching functions.

■Processor-to-processor communication function

Reciprocal communication is realized between the CPU in the server card and the CPU in the switching system. This function allows the switching system to control the server card and also to control in an integrated fashion the switching system, along with other network equipment, with an NMS (Network Management System).

■Allows the installation of several server cards

A number of server cards can be installed on a single ATM Switch. Consequently, this facilitates the scalable expansion of the server according to network size and enables the server to be operated in a redundant configuration. In addition, this feature makes it possible to distribute the traffic that had concentrated in the server with conventional networks.
