Embodiment 9

[0115] The ninth embodiment of the present invention is given below, and the network control device of the present invention is further described in combination with the method embodiments, as follows Figure 11 Shown:

[0116] As mentioned above, the embodiment of the present invention can be applied to various service environments, and the VoIP voice service in the Ad Hoc network is taken as an example for illustration. In the embodiment of the present invention, the network control device includes a destination device and a source device, the destination includes an acquisition module 701 , a first determination module 702 and a feedback module 703 , and the source includes a first receiving module 801 and a first adjustment module 802 .

[0117] In some embodiments, the obtaining module 701 obtains the quality of service parameters of the network, including obtaining the end-to-end delay, delay jitter and packet loss rate of the received data packets, and then obtains acco...

Embodiment approach

[0118] In some implementations, the first determination module 702 may determine the network status by obtaining the number of voice frames that need to be encapsulated in the RTP data packet, and judging the network status according to the obtained number of voice frames. At this time, the feedback information sent by the feedback module 703 may be the number of voice frames that need to be encapsulated in the RTP data packet obtained by the first determination module 702 . The first adjusting module 802 adjusts the number of voice frames encapsulated in the RTP data packet according to the number of voice frames encapsulated in the RTP data packet. In this implementation mode, the source end can adjust the number of voice frames in the RTP data packet in a more real-time and targeted manner according to the network status, effectively reducing network congestion and improving the quality of voice transmission.

[0119] In some implementations, the first determination module ...

Abstract

The embodiment of the invention discloses a network control method and device. The method comprises the following steps: acquiring service quality parameters of a network; determining the network state according to the service quality parameters; and when determining that the network is in congestion state according to the service quality parameters, sending a first feedback information to a source end, so that the source end increases the number of data frame packaged by a packet of a real-time transport protocol (RTP) according to the first feedback information. In the technical scheme provided by the embodiment of the invention, the network state is determined according to the service quality parameters of the network, when the network is in the congestion state, the number of the data frame packaged by the RTP data packets of the source end is increased, thereby effectively reducing the bandwidth required to occupy by the RTP packet; and when the network is congested, the flow can be reduced in time to avoid the re-congestion content, thereby effectively reliving the network congestion and improving the quality of the service transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a network control method and device. Background technique [0002] VoIP (Voice over Internet Protocol) is a technology that uses the Internet for voice transmission. This technology compresses and packets the analog sound signal, and transmits it in the form of data packets in the IP network environment, also known as Internet phone or IP phone. Compared with the traditional telephone, its cost is lower, and it can be more convenient to introduce new multimedia services. [0003] With the gradual maturity of the wireless technology, the wireless ad hoc network (Mobile Ad Hoc Network, Ad hoc network for short) has developed rapidly due to its convenience and speed. It does not rely on the existing network infrastructure, adopts distributed autonomous management, and has the advantages of simple network construction and strong mobility. The wireless VoIP service o...
