[0004] If the NIU of the SMS forwards completely dynamically according to the registration message of the STB and does not generate any static signaling link forwarding relationship table, then when the number or status of SPUs inside the SMS changes, the original dynamically forwarded signaling link may It will change due to this change of SPU (for example, w

Embodiment Construction

[0033] The core idea of ​​the present invention is: establish a new link dynamically, keep the signaling link forwarding relationship table of the existing link on the NIU (network interface unit) after the link is established, and complete the signaling link dynamically by the network interface unit The maintenance of the forwarding relationship table ensures that the existing signaling link will not be affected by the change of the number or status of SPU (Signaling Processing Unit).

[0034] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0035] Attached below figure 1 And attached figure 2 The methods and devices described in the embodiments of the present invention are described in detail.

Abstract

The invention discloses a method and a device for establishing a multi-homing dynamic signaling link. When a tip node initiates a registration request to a streaming media server, the method comprises the steps that: a network interface unit respectively searches corresponding signaling link transmission relationship tables for a plurality of received signaling messages; whether search is successful or not is judged; the signaling messages of search failure are distributed to a plurality of signaling processing units which carry out legal verification to the signaling messages of search failure and notify the network interface unit to establish corresponding signal links for the signaling messages passing the legal verification; the network interface unit establishes corresponding signaling link transmission relationship tables for the signaling messages passing the legal verification; the device comprises the network interface unit and a plurality of signaling processing units. The method and the device, without configuring the address properties of all tip nodes in advance, realize the dynamic establishment of the signal link between the tip node and the streaming media server without the influence of the number change of the internal signaling processing units.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for establishing a multi-homing dynamic signaling link. Background technique [0002] In the application of IPTV (Internet Television) system, the end node STB (Set Top Box, set-top box) needs to complete node registration with SMS (Stream Media Server, streaming media server) through signaling interaction before watching TV programs. [0003] Since the STB may be behind a NAT (Network Address Translation, Network Address Translation) device, its IP address for external communication can be changed freely within the range of the legal address pool of the NAT device, and it is required that all legal STBs can be correctly registered on the SMS And maintain the signaling link, so it is necessary to statically configure the endpoint information of all STBs and the complete two-way correspondence table of the signaling link on the SMS in advance. The NIU (...
