Problems solved by technology

[0023] For LLDP MED media terminals that support multi-channel video, they cannot report real-time traffic to the access switch, nor can they report the number of media stream transmission channels and the actual traffic of each media stream to the access switch. Bandwidth control and quality of service (QoS, Quality ofService) guarantee processing

Embodiment Construction

[0064] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] figure 1 The flow chart of the method for reporting traffic in real time by the LLDP MED media terminal provided by the embodiment of the present invention, such as figure 1 As shown, the specific steps are as follows:

[0066] Step 101: LLDP MED media terminal 1 is powered on, and initializes the total code rate R of each media stream input port of itself i =0, wherein, i represents the serial number of the media stream input port, 0≤i≤m-1, m is the total number of media stream input ports on the media terminal 1, and the total number of media sessions established by the initialization itself is 0.

[0067] For each media stream input port, the LLDP MED media terminal can maintain the network card identification (ID) where the media stream input port is located, the IP address bound to the network card, the total number of m...

Abstract

The invention discloses a real-time traffic reporting method, a media endpoint and a real-time traffic reporting system. The method comprises that: when establishing a multimedia session, the link layer discovery protocol media endpoint discovery (LLDPMED) media endpoint updates the total code rate of each media stream input port used by the session according to the code rate of each media stream input port used by the session, carries the latest total code rate of own initiated media stream input ports into an expanded type length value (TLV) after the establishment of the multimedia session is finished and a media channel is enabled, and transmits the expanded TLV to network access equipment; and the network access equipment receives the expanded TLV, and performs bandwidth control and quality of service (QoS) guarantee processing according to the total code rate of each media stream input port in the expanded TLV. By the real-time traffic reporting method, the media endpoint and the real-time traffic reporting system, the accurate bandwidth control and QoS guarantee processing of the network access equipment is realized.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a link layer discovery protocol (LLDP, Link Layer Discovery Protocol) media terminal discovery (MED, Media Endpoint Discovery) media terminal method, system and LLDP MED media terminal for reporting traffic in real time. Background technique [0002] LLDP MED adds some type length values ​​(TLV, TypeLength Value) on the basis of LLDP. LLDP MED distinguishes between network link devices (such as switches) and media terminal devices (such as IP phones), and media terminal devices can be divided into three categories: MED general terminals, MED media terminals, and MED communication equipment terminals. Each device has different capabilities and functions for issuing and receiving TLVs. Among them, the LLDP MED network link device provides IEEE 802 network access for LLDP MED terminals, which can be Layer 2 or Layer 3 switches, bridge devices, etc.; LLDP MED gener...
