 Development's motivation
|
We do a research about the fee of various international communication method.
- International long distance call
- International ISDN
- Lease line
- IP-VPN
- InternetVPN
>
InternetVPN will be the best solution.
|
| The clarification after investigation
|
| Although the speed of the Internet in China is not so slow, it is not as fast as Japan does.
When the transmission comes to China from Japan, the speed becomes slow suddenly. By different time period,
the connection will be down sometimes.
|
|
Contracting big bandwidth in both Japan and China site, the average speed will be only 66Kbps through FTP transmission.
The electric current is cut off frequently. (Long time)
|
|
If you need to receive a lot of data(several Gbyte), the average speed 66Kbps is very impossible.
|
|
An actual measurement after test (for example: about 8MByte PDF File's Transmission)
|
|
Problem that turns out the InternetVPN
Internet VPN cannot be used as a communication (file transmission) on business
between Japan and China on business.
|
To adopt Internet VPN, other related appliances must be considered. The workload of system management
is needed to reduce. (especially system manager is not existed)
- FireWall VPN？
- Router VPN？
- FireWall setup？
- Invasion Detection (IDS)、Defensive System (ISP)
- Anti Virus solution? (Server? Network? )
- when system manager doesn't exist, what about the solution of FireWall, VPN, IDS, ISP and
Anti Virus?
To develop NetSGX system as a solution
|
 |
The speed after NetSGX's installation (for example: about 8MByte PDF File's Transmission)
|
 |
Appliance's installation
|
There are some necessary things for implementing Internet VPN. The whole network with NetSGX will
be secured by Antivirus while XTP transmission. (Or, to construct Router, Firewall, VPN, Antivirus, IDS, IPS in
one machine is possible).
FTP file server is also pre-installed in NetSGX. (That means the file transmission between Japan and China can be done rigt away
if the both side's Internet connection is ready.)
|
 |
Advantages after NetSGX's installation
|
By the high-speed Internet connection, several 10Kbps connection speed will be increased to Mbps.
In addition, XTP[Not TCP/UDP] and network will be secured by AntiVirus according to high-level secured InternetVPN
under NetSGX.
The other appliances can be supplied in China.
Some of the Internet VPN machines such as Router, Firewall, IDS and etc can be cut down.
The workload of system management can also be reduced.
The machines which connect to Internet, can be protected by high-level security's management.
(forget the patch or log check, attack situaiton and etc)
