Abstract

Disclosed is a mechanism for real-time session control on a reverse proxy server. The real-time session control on a reverse proxy server supervises each session state between a browser and a reverse proxy and between a reverse proxy and a Web server. And the real-time session control cuts a specific session which is abnormal status. In example, a browser and/or a Web server transmits a lot of data to a reverse proxy by some fault, and the real-time session control cuts that session of the browser and/or the Web server, and it prevents a reverse proxy and a network being in a high load state.

Realtime Session Control on Reverse Proxy Server

The real-time session control on a reverse proxy consists of three main idea. The first main idea is 'session-supervising'. This function is supervising each session from the viewpoint of the number of packets and the amount of transaction. The 'session-supervising' also sends notification to an operator. The second main function is 'automatic-session-control'. This function cuts a specific session which is abnormal status. Based on the result of the measurement from 'session-supervising', the 'automatic-session-control' judges whether a session is abnormal. The third main idea is 'operator-control'. This function makes an operator cut a session.

The real-time session control on a reverse proxy has the following function.
(1) The number surveillance of incoming packets and outgoing packets on each session.
(2) The amount surveillance of incoming transaction and outgoing transaction on each session.
(3) The surveillance of the ratio of the number of incoming packets and outgoing packets on each session.
(4) The surveillance of the ratio of the amount of incoming transactions and outgoing transactions on each session.
(5) The function which cuts a specific session, when the measurement result of the above
(1), (2), (3), (4) and (5) is out of range of set-up parameter.
(6) The function which notifies an operator of a measurement result of the above (1), (2),
(3), (4) and (5).
(7) The surveillance of the time which each session has connected.
(8) The function which notifies an...
