Figure 6-5 Networking model of iWeb remote maintenance solution
The iWeb remote maintenance system has the following characteristics:
z Unnecessary to change the original system: Operation and maintenance
personnel can maintain MRS6100 through the iWeb remote maintenance
system in a remote mode.
z Data transfer: A bi-directional data channel is established between the Client
Agent and the Server Agent and between the remote maintenance workstation
and the BAM, to transfer ordinary requests and active reports between the
remote maintenance workstation and the BAM.
z Supporting to traverse Proxy and firewall: MRS6100 supports user
authentication and WindowsNT Challenge/Response (NTLM) authentication at
the Proxy Server. Through the tunnel technique based on hyper text transport
protocol (HTTP), the firewall can open an HTTP port to achieve the traverse
through firewall.
z Encrypting and compressing data: Before being transferred, data are encrypted
to ensure security and is compressed to save the bandwidth.
z Access policy control: authorization based on the IP address of a remote
maintenance workstation, authorization based on a time segment and real-time
authorization for an unauthorized remote maintenance workstation.
z Remote maintenance communication: MRS6100 supports the communication
between remote maintenance personnel and local maintenance personnel in the
text form, thus saving phone call fees during the maintenance.
