Embodiment 1

[0046] The embodiment of the present invention provides a kind of BRAS address renewal method, is applied to above-mentioned BRAS address renewal system, with reference to image 3 As shown in , the method includes:

[0047] S101. The gateway receives a TCP / UDP data packet, and the TCP / UDP data packet encapsulates RTSP (English full name: realtime streaming protocol, Chinese full name: real-time streaming protocol) protocol data.

[0048] At present, the mainstream IPTV service application layer mainly uses the RTSP protocol for streaming media transmission. The RTSP protocol is an application layer protocol in the TCP / IP protocol system, an IETF RFC standard submitted by Columbia University, Netscape and RealNetworks. The protocol defines how one-to-many applications can efficiently transmit multimedia data over IP networks. RTSP is located on top of RTP (full name in English: real-time transport protocol, full name in Chinese: Real-time Transport Protocol) and RTCP (full n...

Embodiment 2

[0070] Embodiments of the present invention provide a gateway device as figure 1 The gateway device 12 shown in is applied to the above-mentioned BRAS address update method, referring to Figure 6 As shown in , the gateway device includes:

[0071] The receiving unit 1201 is configured to receive TCP / UDP data packets, in which RTSP protocol data is encapsulated.

[0072] The judging unit 1202 is configured to judge whether the TCP / UDP data packet is an IPTV service data packet according to the target port number or the RTSP protocol feature field in the TCP / UDP data packet received by the receiving unit 1201.

[0073] The detecting unit 1203 is configured to detect the priority in the TCP / UDP data packet if the judging unit 1202 judges that the TCP / UDP data packet is an IPTV service data packet.

[0074] Sending unit 1204 is used to send the source IP address of the TCP / UDP data packet to the BRAS server if the priority in the TCP / UDP data packet detected by the detection unit...

Embodiment 3

[0084] Embodiments of the present invention provide a BRAS server as figure 1 The BRAS server 13 shown in is applied to the above-mentioned BRAS address update method, with reference to Figure 7 As shown in , the BRAS server includes:

[0085] Receiving unit 1301, for receiving the source IP address of TCP / UDP data packet from gateway, encapsulated RTSP protocol data in TCP / UDP data packet, the source IP address of TCP / UDP data packet is gateway judgment if TCP / UDP data packet is IPTV service data packet, and if the priority of the TCP / UDP data packet is the lowest priority, send it to the BRAS server, wherein, the gateway according to the destination port number in the TCP / UDP data packet or whether the TCP / UDP data packet contains the RTSP protocol Feature field to judge whether the TCP / UDP packet is an IPTV service packet;

[0086] The updating unit 1302 is configured to update the source IP address of the TCP / UDP data packet received by the receiving unit 1301 to the IP...

Abstract

The invention discloses a BRAS address updating method, device and system, relates to the field of communication, and is used for solving the problem that an IPTV service address library of a BRAS server cannot be updated in time when an IPTV service and a broadband service use a same VLAN. The BRAS address updating method comprises the following steps: a gateway receives a TCP / UDP data packet; RTSP protocol data is encapsulated in the TCP / UDP data packet; the gateway judges whether the TCP / UDP data packet is an IPTV service data packet or not according to a target port number in the TCP / UDP data packet or an RTSP protocol characteristic field; if the TCP / UDP data packet is the IPTV service data packet, the gateway detects the priority of the TCP / UDP data packet; if the priority in the TCP / UDP data packet is the lowest priority, the gateway sends a source IP address of the TCP / UDP data packet to the BRAS server; and the source IP address of the TCP / UDP data packet is used for updating the IPTV service address library by the BRAS server. The embodiment of the invention is applied to IPTV.

Description

technical field [0001] The invention relates to the communication field, in particular to a BRAS address updating method, device and system. Background technique [0002] While deploying broadband networks for home users, major operators also provide users with IPTV (English full name: internet protocol television, Chinese full name: Internet Protocol Television) services. When a user uses these two services at the same time, because the IPTV service is sensitive to delay, the viewing experience of the user is poor when the delay is large, while the broadband Internet service has relatively low delay requirements, and the user is more likely to accept the slow opening of the webpage, so it is necessary to Set IPTV business as high priority. One connection method in the current network is that IPTV and broadband use the same service channel, that is, use the same VLAN (full name in English: virtual local area network, full name in Chinese: virtual local area network), at the...
