Detection method of speaker in telephone conference based on NDN

Abstract

The invention relates to a method of detecting a speaker in an ACT telephone conference. The method includes a step 101), a step 102) and a step 103). The step 101) is that in the ACT telephone conference, an audience list is maintained at a conference participant end. The conference participant is informed that a speaking node is arranged as the emerging information of a new speaker by using a broadcast way when the new speaker emerges in conference participants. The step 102) is that the notice is replied by using the maintained audience list after the audience receives the information. Specific information of the new speaker node is inquired by a request packet delivered by an audience node. The step 103) is that the request packet delivered by all audiences is replied by the stored speaker list by the new speaker node. The conference participants comprise all the audiences and all the speakers. According to the detection method of the speaker in the telephone conference based on NDN, the audience is informed passively that the new speaker emerges, thus the expenditure of a listen-in user in the telephone conference is saved. Useless flow transferring of a network is reduced. A network bandwidth load is relieved. The network transferring efficiency is effectively improved.

Description

technical field [0001] The invention relates to a method for detecting a speaker by a user in an NDN-based voice conference. Background technique [0002] ACT (Audio Conference Tool) is a voice conference technology based on NDN. ACT uses content identification to detect conferences and speakers in a meeting, and then obtains voice data from different speakers, instead of relying on the current centralized control service. If a new speaker joins the conference, the listener needs to send interest packets continuously to know the appearance of the new speaker, which causes additional overhead to the user and increases unnecessary traffic on the network. [0003] In NDN, communication is dominated by the receiver, the data requester. Users request data by sending interest packets, which contain the name used to identify the requested data. The router forwards the interest packet by looking up its own FIB (Forwarding Information Base) table, and remembers the port where the ...

Problems solved by technology

[0018] The purpose of the present invention is to overcome the speaker detection method adopted in the ACT teleconference in the prior art, which causes extra overhead to the user, increases unnecessary traffic on the network, and then causes problems such as network congestion to a certain extent , thereby providing a method and system for detecting speakers in an ACT teleconference
