Outside ALG Interface
This function enables an outside application to retrieve or control information such as
NAT/PT conversion information, firewall blocking information, and VPN tunnel informa-
tion processed in the data server. It allows control packets used for H.323, VoIP networking,
and IP phones operating on the Call server, to be smoothly serviced without blocking.
Network Load Balancing (NLB)
Network Load Balancing (NLB) has two purposes: NLB and Failover. The NLB function
extends system bandwidth by automatically distributing the network traffic to external
networks if there is more than one external network. The Failover function normalises net-
work communication via another external network if a link failure occurs in part of the ex-
ternal network. In other words, network communication is always available unless a link
failure occurs in all external networks.
System Management Interface
This function allows the administrator to report and manage alarm, event, traffic, and log-
ging information, including IDS information, using the system administrator package
through TCP/UDP. Reporting can be optionally specified based on the management data
type.
Management Functions (Web/CLI/SNMP/RMON)
y
CLI: Used for configuring the data server function using the CLI (Command Line Inter-
face) on the Telnet.
y
Web: The administrator can configure and view the operation of the data server func-
tional block using the web browser.
y
SNMP: SNMP agent collects and stores device information according to the specifica-
tion (MIB) installed and determined at each network device. The SNMP manager
manages the overall network by collecting the information from SNMP agents distrib-
uted around the network.
y
Remote Monitoring (RMON): Network traffic can be checked and analyzed via
4RMON groups (history, statistics, alarms, events).
