STUN Technology:
That is, serial tunnel technology. This technology is to send the SNA software package from the serial port of FEP (3745/6) to the router, package it into an IP packet through the router, and then transmit it in a network composed of the router. After it is unpacked and restored to the SNA through the router, the SDLC packets restored to the SNA are sent to the SDLC interface device.
CIP technology:
CIP is a channel interface processor. It is a card device that can be easily installed in the CISCO7000 series routers. CIP provides IBM computers with access capabilities for multi-protocol inter-networks through direct connection with the channel of IBM computers. Provide TCP/IP, SNA, APPN traffic to the main machine, thus eliminating the need for intermediate devices such as 3172 interconnect controllers and IBM3745/6 FEP.
DLSw technology:
It is an international standard technology. It can package the SNA software package through IP and then transmit it from the IP network to any router node on the IP network, and then transmit it through the router's serial port to the SDLC interface device or the SNA node (such as RS6000) that transmits SNA packets through the LLC2 link layer protocol.
An E1 interface of MIP:
It can provide 30 sub-channels of 64Kbps, and the channels can also be combined into larger sub-channels of N×64K, which is enough to meet the bandwidth needs of connecting with municipal banks for a considerable period of time.
CiscoWorks：
Network management applications are a series of SNMP-based management application software that can be integrated on SunNet Manager, HP OpenView, IBM NetView/AIX, Windows95/NT platforms. The main functions provided are:
Allows the remote installation of new routers with neighboring routers to provide a wide range of dynamic status, statistics, and configuration information for Cisco's Internet products, intuitively graphically displaying Cisco's devices, and basic troubleshooting information. Audit and record configuration files changes, detect unauthorized configuration changes on the network, facilitate configurations of similar routers in the network to record the contact details of a specific device to view the status information of a device, including buffer memory, CPU load, available memory, interfaces and protocols being used to collect historical data of the network, analyze network traffic and performance trends, and graphically display it to establish authorization checkers to protect CiscoWorks applications and network devices from access by unauthorized users.
In particular, in order to manage SNA Internet well, Cisco has specially developed CiscoWorks Blue network management application for IBM network management. In addition to supporting the above functions, it also adds SNA-type MIBs in routers, supports NMVT and LU6.2 management methods, and provides SNA management-related functions, such as: knowing the status of each SNA resource in the network, and using it to change the status of SNA resources to help detect problems related to the delay of network data flow, which can be used to measure the response time from the host to the LU.
