Problems solved by technology

[0006] In the first admission control method, if multiple users want to watch unicast video, there may be a problem that the unicast bandwidth is insufficient and the multicast bandwidth is not utilized, and vice versa, resulting in low bandwidth utilization; the second method In the admission control method, the bandwidth negotiation between DSLAM and RACS is only realized in the xDSL scenario, and it is not applicable to the FTTx (Fiber To The x, collectively referred to as various fiber applications such as fiber to the building and fiber to the home) scenarios bandwidth negotiation, therefore, cannot fully meet the needs of operators for bandwidth negotiation

Embodiment 1

[0070] This embodiment provides an admission control method, which divides multiple multicast bandwidth management devices into different levels according to different bandwidth control granularities. When a user applies for multicast video, refer to figure 1 , the method flow is as follows:

[0071] 101: The multicast bandwidth management device receives the user's multicast video application;

[0072] 102: Determine whether the available multicast bandwidth meets the requirements of the multicast video application; if not, execute 103; otherwise, execute 104;

[0073] 103: The user is refused to watch the multicast video, and the process ends;

[0074] 104: Determine whether there is an upper-level device, if yes, execute 105, otherwise, execute 106;

[0075] 105: Forward the user's multicast video application to the upper-level device, and the upper-level device decides whether to accept the user to watch the multicast video, and the process ends;

[0076] 106: Accept th...

Embodiment 2

[0084] This embodiment provides an admission control method, which divides multiple multicast bandwidth management devices into different levels according to different bandwidth control granularities. This method is aimed at FTTH (Fiber To The Home, Fiber To The Home) application scenarios. The broadcast bandwidth management device is RACS, and the multicast bandwidth management device is OLT (Optical Line Terminal, optical line terminal); For a detailed description of the method, see image 3 , when the user goes online, the OLT reports the user line ID (Identifier, identifier) ​​to the BRAS (Broadband Remote Access Server, Broadband Remote Access Server), and the BRAS forwards the received line ID to the RACS. Among them, the message of the line ID is defined as:

[0085] ANID xpon Frame_ID / Slot_ID / Sub-Slot_ID / Port_ID: ONT_ID.GemPort_ID.VLAN_ID; among them, ANID indicates the ID of the OLT; xpon indicates that this is the PON (Passive Optical Network, Passive Optical Networ...

Embodiment 3

[0098] This embodiment provides an admission control method. In order to further explain the method, for the FTTH application scenario, this embodiment will combine several different situations in the first-level bandwidth negotiation scenario to make a detailed description of the method provided in this embodiment. Detailed explanation.

[0099] see Figure 5 , taking the first-level bandwidth negotiation scenario, when the user applies for unicast video, the RACS bandwidth for managing unicast bandwidth is sufficient, and there is no need to borrow bandwidth as an example. The process is as follows:

[0100] 501: The user sends a unicast video request to the VoD server;

[0101] 502: the VoD server applies for unicast bandwidth from the AF;

[0102] 503: AF applies for unicast bandwidth from RACS;

[0103] 504: RACS judges whether there is enough remaining unicast bandwidth—the result is that there is enough remaining unicast bandwidth;

[0104] 505: RACS allocates unica...

Abstract

The invention discloses a method, a system and equipment for admission control, and belongs to the field of communication. The method comprises the following steps of: when the request of multicast video from a user is received, admitting the user to watch the multicast video only when ensuring that each multicast bandwidth management equipment has enough surplus bandwidth; and if the multicast bandwidth management equipment does not have enough bandwidth and borrowing of the bandwidth from unicast bandwidth management equipment fails, refusing the user to watch the multicast video. The system comprises the unicast bandwidth management equipment and the multicast bandwidth management equipment. By the method, the admission control based on a passive optical network is realized by the bandwidth consultation between the unicast bandwidth management equipment and multicast bandwidth management equipment at each layer, and the effects of the bandwidth consultation between two layers or among multiple layers is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to an admission control method, system and equipment. Background technique [0002] With people's demand for network services, services such as IPTV (IP Television, IP TV) and VoD (Video on Demand, video on demand) have become increasingly important. Quality, to bring users a good experience, when accepting users' network services, some control measures should be taken, which are called admission control. [0003] An admission control method in the prior art is: in xDSL (Generic Digital Subscriber Line, various digital subscriber line) scenarios, video bandwidth is statically divided into unicast bandwidth and multicast bandwidth, and the DSLAM (Digital Subscriber Line Access Multiplexer, digital subscriber line access multiplexer) manages multicast bandwidth, and RACS (Resource and Admission Control Sub-System, resource admission control subsystem) manages unicast bandwidth; when...
