Abstract

A network grouping system and a network grouping method thereof are provided. The network grouping system includes a controlling server and a connecting server. The connecting server connects to the controlling server via a switch. The connecting server embeds a grouping identifier into a network packet, and transmits the network packet to the controlling server via the switch. The controlling server retrieves the grouping identifier from the network packet, and creates a grouping configuration according to the grouping identifier. The grouping configuration records a matching relation of the grouping identifier with the connecting server. The controlling server further transmits the grouping configuration to the switch so that the switch passes on network packets according to the grouping configuration.

a connecting server, having a physical connection with the switch;

wherein the connecting server converts a grouping identifier into a piece of network information, embeds the network information and a controlling code into a network packet, and transmits the network packet to the switch via the physical connection so that the switch transmits the network packet to the controlling server, and the controlling server retrieves the controlling code and the network information from the network packet, converts the network information into the grouping identifier according to the controlling code, creates a grouping configuration according to the grouping identifier, and further transmits the grouping configuration to the switch so that the switch passes on the network packet according to the grouping configuration, wherein the grouping configuration records a matching relation of the grouping identifier with the connecting server;

wherein the controlling code is used to notify the controlling server that the network information of the network packet is data into which the grouping identifier is converted,

wherein the network information further comprises one of a network IP address, a Media Access Control (MAC) code, a connecting port code, and combinations thereof.

4. The network grouping system as claimed in claim 3, wherein the grouping configuration further records a matching relation of the grouping identifier with another connecting server so that the switch transmits the network packet between the connecting server and the another connecting server which have the same grouping identifier according to the grouping configuration.

5. A network grouping method for a controlling server, the controlling server being used in a network grouping system which further comprises a connecting server, the connecting server having a physical connection with a switch, and the controlling server connecting to the switch, the network grouping method comprising:

(a) the controlling server receiving a network packet from the connecting server via the switch;

(b1) the controlling server retrieving a controlling code and a piece of network information from the network packet;

(b2) the controlling server converting the network information into a grouping identifier according to the controlling code, wherein the controlling code is used to notify the controlling server that the network information of the network packet is the data into which the grouping identifier is converted;

(c) the controlling server creating a grouping configuration according to the grouping identifier, wherein the grouping configuration records a matching relation of the grouping identifier with the connecting server; and

(d) the controlling server transmitting the grouping configuration to the switch so that the switch passes on the network packet according to the grouping configuration,

wherein the network information further comprises one of a network IP address, a Media Access Control (MAC) code, a connecting port code, and combinations thereof.

6. The network grouping method as claimed in claim 5, wherein the grouping configuration further records a matching relation of the grouping identifier with another connecting server so that the switch transmits the network packet between the connecting server and the another connecting server which have the same grouping identifier according to the grouping configuration.
