Even there are no dedicated server load balancer units, this function performs load leveling for individual servers by distributing access to multiple servers (L-Servers) on an L-Platform, providing stable response and flexible scalability.
NS option is necessary for this function.
NS option provides the following functions for ensuring stable response from servers (L-Servers).
Server Load Balancer Function
Server Distribution Method
Server (L-Server) distribution using round robin or an algorithm with a simple minimum connection number can be performed.
Server Failure Monitoring
Failure monitoring of servers (L-Servers) can be performed using PING monitoring, service monitoring, or HTTP application monitoring.
Web Acceleration
The load on the web server (L-Server) can be reduced, and the number of TCP connection establishment processes for each access from the client can be kept low by establishing the TCP connection between an NS appliance and the web server.
Session Maintenance (Guarantee of Uniqueness)
It is possible to transfer a series of packets (transaction) for certain duration, on a node or connection basis, to the same server as was previously accessed.
Access Limitation
Stable operation of the distribution target server (L-Server) can be guaranteed by limiting the amount of access.
SSL Accelerator
This function enables load distribution by converting HTTPS to HTTP communication, and improves the high availability of web servers (L-Servers).
