ETHERNET OVER SYNCHRONOUS DIGITAL HIERARCHY SYSTEM AND METHOD FOR SUPPORTING THE DIRECT COOPERATING OF SYSTEMS NETWORK ARCHITECTURE AND THE TRANSMISSION CONTROL PROTOCOL/INTERNET PROTOCOL

摘要

The present invention relates to a network interworking system and method, in particular for the extension of the remote network from the Internet SNA (Systems Network Architecture) protocol and the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol is directly because it works, IBM without adding a built TCP / IP network and the host of the equipment of the gateway for SNA and works related to network interworking system and method is interlocked as possible.; Conventional network interworking system is an IBM host products currently used in the majority of financial institutions such as banks, insurance companies are built using a unique protocol of SNA. In other words, in computing the traditional banking system, the IBM host environments are located in the same place, all IBM hosts were able to communicate only with SNA protocol.; However, we must take the measures up to the 9/11 attacks in the US occurred in 2001 disability in the financial sector have IBM host (Disaster Recovery) DR. Thus, using the mass transfer equipment to measure the potential for failure from, and dual computational facilities in the province and separate networks. Here, SNA protocols are separate, such as the gateway for TCP / IP protocol directly are not interlocked, in many cases indexation is TCP / building IP networks and, SNA and linked to a remote network, expansion of the IBM host the equipment we have to be added.; A system for a network linkage of this type of SNA protocol, was to have a like number of problems factors, related to the failure of the commercial server of a CPU, memory, and so limit, the program of the processing capacity, IP equipment, various types of network devices, such as transport equipment the building, and the like need to add a separate gateway, causing the network configuration becomes complicated. Thus, a situation that can not only reduce the effect of interest satisfy network configuration.; The present invention is mounted in the same system also SNA protocol, the communication protocol of IBM host, so as to directly be able to service the Ethernet signal of 10/100 BaseT, IP equipment and transmission equipment incorporating a single device SNA and TCP / to support the direct linkage of IP (Ethernet over SDH) EoS provides a system and method.; Also, SNA and TCP / for direct interworking of IP (Ethernet over SDH) EoS system 100 is a system for network linkage of the SNA protocol, across the backbone network (BKN) IBM computer 10 side and an IBM computer 10 and the first transmission equipment (118) installed in the transmission direction, the IBM computer (10 ") side transmission equipment a direction IBM computer 10 'and transmission devices 118' are installed.; Therefore, the system for network linkage of the SNA and TCP / IP protocol, IP equipment, building a variety of network devices, such as transport equipment, and does not add a separate gateway, the cause of the error caused by the complexity of the network configuration greatly reduced do.
