implementation into embedded system are main drawbacks for their practical application.
Because of the rapid development of Ethernet, the scare of real IP shortage becomes a serious
issue when an enterprise continues its IA growth. It is a resource waste and cost a large expense
that every individual host has its own real IP inside the enterprise's network. Privates IPs and
NAT function (provided by router, gateway or IP sharing) provide a solution to the shortage of
real IP, but new issue gives rise to that remote user from internet has no access permission into
the private IP domain, thus an administrator has no choose but accesses the private IP devices
from the very location of the local area network to trouble shoot any problems that network
clients report, until now "Single IP-Agent mode", one of this switch special features, provides a
new solution for all issues above.
There are benefits of "Single IP-Agent mode":
1. Reduce the demand of real IP (public IP).
Since there are up to 32 devices which have a IP agent as "Single IP" switch, meaning that
the switch becomes a network agent and handles all functions of these devices, MIS can
reduce the number of hosts that are directly connected to internet, and make use the saved
real IPs more efficiency.
2. Integrate network devices without modifying hardware or software.
"Single IP" is a technique mainly based on application layer in OSI standard. The
connection between master and slave hosts is linked by Ethernet protocol. It is little concern
of hardware and packet transmits. Modifications of hardware or software of the slave hosts
are not necessary. Thanks to the characteristics, single IP switch gives the best compatibility
with other network devices, router, gateway, web server and even another brand switch.
3. Handy User interface without learning complex setting or changing user's habit of
operation.
A floating menu gives a comprehensive user interface for administrator to pick the managed
devices. It provides host IP and host name in the same time, saving the trouble that the
administrator tries to remember which IPs those slave hosts are assigned to. Since there is
only one browse windows displaying on the screen in the same time, agent manager play a
role like as TV channel controller. Administrator can easily switch to the device he/she
wants and enter the setting webpage as did before.
4. Totally remote control of network devices in private IP domain.
It is not necessary for MIS to put all devices together in one place. Single IP function will
operate normally no matter how far the distance is between the master and the slave hosts if
their packets can reach each other in local area network. Moreover, a remote administrator
can access the far-side servers in the private domain through the intermediary of single IP
switch, which is directly connected to Internet.
