Abstract

A method and device for making clients rapidly access to the peer-to-peer network comprise that the accessed clients, which are separated into one or more normal state groups; the clients that intend to log in are separated into one or more login groups; and the required contents, the variant of the contents or the content-related information are selectively transmitted to the members of the login groups immediately. After a certain login group becomes stable, the normal state groups which the login groups intend to be added into are selected and each member of the login groups is added into the selected normal state groups. In this invention, there is no need to frequently send notification individually when each client loges in, rather than send group notification, thus it can reduce network dithering, at the same time the user can receive the content or the related variant of the content immediately and watch the playing of the content without any wait when accessing to the network.

Claims

1. A method for making clients rapidly access to a peer-to-peer network comprising the following steps:

A1, establishing one or more normal state groups for accessed (logged in) clients;

B1, establishing one or more login groups for the clients that intend to log in;

C1, selectively transmitting required contents, variant of the contents or content-related information to the members of the login groups immediately;

D1, selecting, after a certain logging group becomes stable, the normal state groups which the login groups intend to add into;

E1, adding each member of the login groups into the selected normal state groups.

2. The method according to claim 1, wherein in the step B1, the client that intends to log in is added into the login group with the same attributes;

if there is no such a login group, a new login group with the same attributes will be created and the said client will be added into the newly created group with the same attributes.

3. The method according to claim 1, wherein in the step D1 whether the login group is stable is determined through the following steps:

D11, the number of the members in the login group is detected;

D12, whether the number of the members in a login group is larger than or equal to the predetermined value is determined;

if yes, the login group can be regarded as stable;

if not, a step D13 is executed.

D13, whether the time during which the login group waits to be added into the normal state group is longer than or equal to a first predetermined time is determined;

if yes, the login group can be regarded as stable;

if not, the process continues to wait.

4. The method according to claim 3, wherein the normal state group which the login group intends to be added into is selected in step D1 through the following steps:

the normal state group with the same attributes is selected;

if there exists the normal state group, determining whether the number of the members in a login group is less than a predetermined value;

if yes, the normal state group with fewer members is selected as one that the login group intends to be added into for system balance;

if there is no normal state groups whose number of members is less than a predetermined value, another group with the same attribute is added as the normal state group which the login group intending to be added into;

if there is no normal state group with the same attributes, a new such normal state group is created as the normal state group which the login group intends to be added into.

5. The method according to claim 4, wherein comprising the following steps:

for both each normal state group and each login group, control datasets are established, which record the attributes of each member in the state and login groups, and at least comprise necessary data for mutual communication among each member and marks of reflecting changes of the control dataset.

6. The method according to claim 5, wherein the login group continuously receives new members, and makes reflection on the control dataset after the step B1.

7. The method according to claim 6, wherein a normal state control dataset of the selected normal state group is transmitted to the login group in the step E1.

8. The method according to claim 7, wherein comprising the following steps after step E1:

F1, the normal state control dataset of the selected normal state group is updated;

H1, the updated normal state control dataset is transmitted to all members of the normal state group.

9. The method according to claim 5, wherein the steps for maintaining the control dataset:

A2, a server monitors connection and disconnection requirements and communication statuses of the clients that participate in content transmissions, makes changes reflected in the control datasets, and marks the changed control dataset.

B2, the updated control dataset is transmitted to each client through the following steps;

B21, depending on the existing control dataset, the server divides changed parts of the control dataset or the variant of the control dataset into blocks, then respectively transmits the blocks to part or all members;

the members transmit the received blocks from the server to other members in the same group again.

B22, if there is no previous control dataset for members, the whole control dataset or its variant will be transmitted by the server to members.

10. The method according to claim 5, wherein a P2P transmission can be used in transmission of contents, variant of contents or content-related information to the login groups by a server in step C1, through the following steps:

the contents, the variant of the contents or the content-related information to be transmitted are divided into blocks, which then are respectively transmitted to part or all members in the login groups;

the members will transmit the received blocks from the server to other members in the same group again.

11. The method according to claim 7, wherein after being stable, the login group is transferred to a transition group as a whole in step D1.

12. The method according to claim 11, wherein after the transmission of the control dataset of the selected normal state group to all members is finished, or after a second predetermined time, the transitional group is added into the selected normal state group as a whole.

15. A computer readable medium with computer executable programs that can be executed by a computer to perform the steps in claim 1.

16. An executable program used in server computers, which can be executed by the server computer to perform the steps in claim 1.

13. A device for making clients rapidly access to peer-to-peer network comprising:

a login processing module for creating one or more login groups for clients intending to log in;

a transmission module for transmitting required contents, variant of contents or content-related information to the clients;

a login detection module for detecting a stability of the login groups and outputting a notification of the stability when the login group becomes stable;

a selection module for selecting a normal state group that the login group intends to be added into after receiving the stability notification of the login group;

a normal state group processing module for creating one or more normal state groups for the login clients, and adding the members of stable login groups into selected normal state groups.

14. The device according to claim 13, wherein further comprising a control dataset establishing and maintaining module and a control dataset transmission module, for each normal state group and each login group the control dataset establishing and maintaining module establishes control datasets, which record attributes of each client in a group, and at least comprise the necessary data for mutual communication among each member and marks of reflecting changes of the control datasets;

each control dataset is transmitted to a corresponding group through the control dataset transmission module.
