Intranet / Internet access to 3Com's proposed program

(A) large-scale nodes program
Remote port number for those who demand more than 16, larger nodes (such as a bank headquarters, major securities firms, insurance, etc.), recommended the program as shown below.



In this scheme, the remote user via telephone network / ISDN network to access the bank transferred to Total Control internal network information resources. 3Com Total Control is provided using the chassis structure of the large-scale access to the server. Line situation the user can access through E1/PRI digital lines, or through an analog phone line / ISDN access. Total Control common 16 slots available, the use of low-density Modem card case, available 60 Modem port Modem card in the high density case with up to 420 Modem port. Usually, Total Control is equipped with network management card, NETServer card and matching the user port number and the corresponding Modem module.
3Com Total Control uses the award-winning Courier V. Everything V.34 Modem Technology and X2 technology to provide network access security to security, billing, dynamic IP address assignment functions, particularly suitable to large-scale network demands.

(B) small-scale nodes program
For smaller nodes (such as provinces and cities row line), we propose to adopt the program as shown below.



Program in the network, remote user telephone network / ISDN network dial NETServer Plus 8 / 16 to visit the bank's internal information resources. NETServer 8 / 16 is the 3Com provides fully integrated remote access servers, especially for cities in the province of rows and rows of the remote access needs. NETServer 8 / 16 with the award-winning 3Com Courier V. Everything V.34 Modem Technology and X2 technology, and remote LAN dial-up access, LAN-to-LAN routing, terminal server with advanced management features, security, call billing functions combination. This makes the equipment costs, eliminating cable clutter and reduce equipment maintenance pressure, reduce user overhead. NETServer 8 / 16 ease of installation, equipment start running fast, simply insert one end of a standard telephone line, LAN can access the other side.

Different services while achieving
Reflected the needs of a variety of business demand for the product can be reflected in: business of priorities to achieve good security and good network management.

If the required number of different businesses have different priorities, and ensure that certain operations have priority over other business, the better to achieve is: to different business fixed at a different port, the high priority assigned more business port, while the low priority assigned the business is relatively less number of ports to ensure that business priorities.

For example: a bank in a 16-port NETServer/16 as access to the server to use, in several business, e-linked banks and credit card high priority, and Intranet, E-Mail a relatively low priority. In this way, we can assign NETServer ports 1 and 2 devoted to Intranet services, ports 3 and 4 devoted to E-Mail service, port 5 to 6 business specializing in financial systems, ports 7 to 11 business electronically linked banks, while the credit card business through the NETServer port 12 to 16 to conduct. Corresponding to different ports business has the same phone number. If the access server is the Total Control, the same methods and NETServer.

For banks and other financial network security considerations, for some may also be used for many business users can set the corresponding filter their (Filter) to define what number it is allocated for what can only business. Total Control, and / or NETServer filter is mainly used in inter-bank network throughout the banking network or the edge of its main functions are: As noted in the data through the network interface header information, to receive or reject the adoption of specific data packets, so as to control network data transmission. Filters to provide different functions:

• Input and output packet filtering
Can be used to control the input or output packets.

* Source address and destination address filtering
According to the packet source address and / or destination address to decide whether to accept or reject the packet.

* Protocol filtering
According to the input and / or output direction of the network protocol packet to decide whether to accept or reject packets.

* The purpose and the source address port filtering
According to local and / or remote users to access services (such as TCP and UDP port number) to decide whether to accept or reject the packet.

* Call filtering
Used to determine whether a packet is an outbound call initiated.

* Route Filtering
Exchange routing table information to filter the data packet's source address and / or destination address, such as the RIP package.

• Establish a session filter
Only allows local users and remote network connections and allowed remote users to access the local network, or vice versa.

Once the Total Control and / or NETServer filter, the filter can be assigned to a specific port or user.

Program features
* High reliability
NETServer 8 / 16 set of traditional access servers, terminal servers and Modem in one, and Total Control of Modem card and NETServer card through the backplane between the bus connection, it eliminates the need for traditional access to the server and the Modem cable between the line, reducing single points of failure and increase reliability.

• Advanced Modem Technology
Whether NETServer 8 / 16, or the Total Control, support 3Com's leading V. Everything technology and X2 technology, and can be upgraded to 56K (V.90) standard.

* Unified management
Can be achieved through the same network management system and access the server on the same Modem management.

* Flexible billing function call
Support for Radius, the user needs to provide call billing functions.

* Powerful Security
In addition to the user through the Radius authentication, the port can be set for each user or the appropriate firewall or filters. These safety measures not only within the settings in the device can also be set in the Radius Server.

Good scalability
When the user increases, NETServer 8 / 16 to upgrade to Total Control without changing the existing security, management and billing tools. Total Control of NETServer card and NETServer 8 / 16 using the same technology.
