LINEAR CONNECTION BASED 3-CHANNEL GATEWAY WHICH DOES NOT ADMIT EXTERNAL ACCESS OF SECURITY REGION

摘要

Purpose: based on do not allow a security region 3 channel gateways accessible from the outside linear connection be provided to bidirectionally transmission mass data be passed through one desired by the time and receive reaction about the mass data of transmission and be passed through in all systems of security region and the service area that is passed through in a state, wherein blocking all access paths from an external firewall system. Construction: a business logic server (D200) is among HTML (hypertext markup language) agreement by column request positioned at the connection of grouping Relay Server (D300) of the outside of a firewall system (D600). Grouping Relay Server (D300) recognizes subsequent request. Business logic server (D200) passes through the connection of text/audio request grouping Relay Server (D300) among HTML agreements. Grouping Relay Server (D300) recognizes subsequent request. Business logic server (D200) obtains the connection of text/plain request grouping Relay Server (D300) by one among HTML agreements. Grouping Relay Server (D300) recognizes subsequent request.
