Introduction to Routing Technology

STUN Technology:

That is, the serial tunnel technology. This technology sends the SNA software package from the serial port of FEP (3745/6) to the vro, Which is packaged into IP data packets and then transmitted in the network composed of routers, then, the SDLC data packets restored to SNA are sent to the SDLC interface device after the router is split.
　

CIP technology:

CIP is the Channel Interface Processor ). It is a plug-in card device that can be conveniently installed in the CISCO7000 series router. CIP is connected directly to the IBM mainframe to provide multi-protocol inter-network access for the IBM mainframe. Provides TCP/IP, SNA, and APPN traffic for large machines, thus canceling the need for intermediate devices (such as 3172 interconnected controllers and IBM3745/6 FEP.
　

DLSw Technology:

It is an international standard technology that can package SNA software packages in IP Mode and then transmit them to any vro node on the IP network, the SNA node (such as RS6000) that transmits SNA data packets to the SDLC interface device or the Ethernet interface (or token ring) interface device through the router serial port ).
　

An E1 interface of MIP:

It can provide 30 64 Kbps sub-channels, and can also be combined into a larger sub-channel of N × 64 KB, which is sufficient to meet the bandwidth requirements for connecting to the local cities for a long time.
　

CiscoWorks:

Network management applications are a series of SNMP-based management applications that can be integrated on the SunNet Manager, HP OpenView, IBM NetView/AIX, and Windows95/NT platforms. They provide the following functions:

Allows remote installation of new routers using neighboring routers to provide a wide range of dynamic status, statistics, and configuration information for Cisco's Internet products, visually displaying Cisco devices, and basic troubleshooting information. Audits and records configuration file changes, and detects unauthorized configuration changes on the network. This allows you to conveniently view the status information of a device by recording the contact information of a specific device in the configuration of similar routers in the network, including buffer memory, CPU load, available memory, APIs and protocols used to collect historical network data and analyze network traffic and performance trends, the authorization check program is displayed graphically to protect CiscoWorks applications and network devices from unauthorized user access.
In particular, Cisco has developed a CiscoWorks Blue network management application for IBM network management to manage SNA networks. In addition to the above features, in addition, the SNA-type MIBs in the vro are added. The NMVT and LU6.2 management modes are supported to provide SNA management functions, such as knowing the status of each SNA resource in the network, it is used to change the SNA resource status to help detect problems related to the delay of network data streams and to measure the response time from the host to the LU.
