Abstract

An integrated managing method for LAN switching devices. The switching device broadcasts a register message including switching device address identification on a port connected to a managing device, the managing device executes a register operation , and sends back a register response message, the switching device sends a handshaking message to the managing device after receiving a successful register response message, and the managing device sends back the communicating response message. If the switching device does not receive the response message within a designated time, it indicates that communication is interrupted and the register operation starts again. During the communicating, process the managing device manages the switching device, and the switching device sends back the response message to the managing device according to the operation result. The need to assign IP addresses is thus reduced or eliminated.

Claims

1. An integrated managing method for switching devices of Local Area Network, comprising:

(A) a switching device broadcasting a register message including an address identification of the switching device to a port connected to a managing device, the managing device executing a register operation after receiving the register message, and sending a register response message to the switching device;

(B) the switching device sending a handshake message to the managing device after receiving a successful register response message, the managing device sending a handshaking response message to the switching device, after the switching device receives the handshake message response, the switching device handshaking with the managing device, and the managing device managing the switching device during the handshaking process;

(C) determining whether the handshaking occurs within a specified time, if not, returning to step (B), otherwise e returning to step (A).

2. The integrated managing method for switching devices of Local Area Network of claim 1, wherein said step (A) further comprises:

an upper switching device inserting location information of the switching device to the register message after receiving the register message from the lower switching device, and transmitting the message to the upper switching device.

3. The integrated managing method for switching devices of Local Area Network of claim 1, wherein said step (A) and step (C) comprise:

when the data needs to be configured, the switching device sending a request message to configure data to the managing device, the managing device sending configured data to the switching device after receiving the message.

4. The integrated managing method for switching devices of Local Area Network of claim 1 wherein said step (B) further comprises:

when the switching device does not receive the handshaking message response within a predetermined period, restarting the register process.

5. The integrated managing method for switching devices of Local Area Network of claim 4, wherein:

the information transmitting between the managing device and the switching device is realized by a message comprising a public message heading, managing message and Ethernet heading;

6. The integrated managing method for switching devices of Local Area Network of claim 5 wherein the public message heading comprises one or more of the following fields:

version number, to indicate a version of current managing protocol;

C, to indicate whether a current message is response message or command message;

Type, to differentiate integrated management from two-layered multicast group control message;

F, to identify whether a frame serial number is effective;

R, to identify whether a check sum is effective;

B, to identify whether a feedback word is effective;

frame serial number, to indicate a message serial number according to each network switching device;

check sum, to check message data;

length of message, to identify length of a message;

feedback word, to indicate response the untouched feedback data by message;

media access control (MAC) for switching device (LAN Switch);

used to identify managing MAC addresses of the switching device;

a first transmitting port number, a second transmitting port number, a third transmitting port number, and a fourth transmitting port number, to record an inlet port number after messages are transmitted by the switching device;

7. The integrated managing method for switching devices of Local Area Network of claim 5 wherein the managing message comprises:

home command word, to act as a home command word of managing message;

sub-command word, to act as a sub-command word of managing message;

length of content, to record length a of content of the managing message;

content of the managing message, to record parameters and data carried in the managing message.

8. The integrated managing method for switching devices of Local Area Network of claim 1,

wherein:

in step (B), the managing device managing the switching device, comprises querying data of the switching device, and performing a configuration process according to the following steps;

(D) the managing device distributing a configuring parameter message or querying parameter message to the switching device according to the need of managing;

(E) the switching device receiving the message, determining the type of the message, if it is the configuring parameter message, processing to step (F), if it is querying parameter message, processing to step (G);

(F) examining whether the configuring data of the message is correct, if the configuring data is not correct, filling in an error code in a corresponding returning record;

if the configuring data is correct, the switching device being assigned with the configuring data, and the assigned result being reported to the managing device, then ending the operation;

(G) examining whether the querying parameter of the message is correct, if the parameter is not correct, filling in an error code in a corresponding returning record;

if the parameter is correct, the switching device being queried according to the parameter, and the queried result being reported to the managing device, then ending the operation.

9. The integrated managing method for switching devices of Local Area Network of claim 1, wherein in step (B), the managing device managing the switching device, comprises:

a managing process of a r multicast group, comprising;

a user entering the multicast group, the user leaving the multicast group and the switching device transmitting a two-layered multicast message.

10. The integrated managing method for switching devices of Local Area Network of claim 9, wherein the process of the user entering the multicast group comprises:

H) the managing device sending a general query message in Internet Group Management Protocol to ports at a user side;

the switching device transmitting the message to user side ports;

I) the user sending a REPORT message, the switching device sending upward to the managing device after receiving the REPORT message from user; and

J) the managing device determining whether the user can enter the desired multicast group according to the REPORT message from the user, if no, losing the REPORT message, otherwise transmitting a message of the user entering the desired multicast group to the switching device, the switching device allowing the user enter the desired multicast group after receiving the message.

11. The integrated managing method for switching devices of Local Area Network of claim 9, wherein the process of the user leaving the multicast group comprises:

K) the managing device sending a general query message to side ports of users within a specified time, the switching device transmitting the message to users after receiving the message;

L) if the managing device sends general query message but does not receive a REPORT message of some multicast group within a specified time, the managing device deleting the multicast group; and

M) when the managing device receives the request message of leaving multicast group, the managing device sending down corresponding query message of multicast group, if a REPORT message is not received within a specified time, the managing device deleting the multicast group.
