Embodiment Construction

[0050]The core of the present invention is to set a 1-bit discarding enable bit, the access device sets the discarding enable bit of the user service according to the user’s service flow and the user’s basic bandwidth. When other devices determine that the service needs to be discarded, the The value of the discard enable bit carried in the service is used to discard the service.

[0051] The following further describes the technical solution provided by the present invention based on the core idea of ​​the present invention.

[0052] The other devices in the present invention are network devices other than the access device that need to continue to transmit the user service traffic transmitted by the access device, such as figure 1 For advanced user 1, device 1 is its access device, and device 3 is other devices.

[0053] The access device of the present invention first needs to set a 1-bit discard enable bit in the user's service. The discard enable bit can be set in the VLAN T...

Abstract

The invention relates to a method for recognizing the service models QoS in the Ethernet. It is characterized in that: setting 1bit of loose bit; access device, based on the service flux and the basic wideband of user, sets the loose bit of user service; other device throws said service, according to the loaded loose bit. The invention uses 1bit to mark the loose ability of service, as using the fixed 1bit of user_priority / PCP region of VLAN TAG, to simplify the code method of VLAN TAG. And the invention can assure the basic wideband of user, to simplify the realization of QoS.

Description

Technical field [0001] The present invention relates to the technical field of differentiated service modules, in particular to a method for realizing QoS of differentiated service models in Ethernet. Background technique [0002] In broadband networks, QoS (Quality of Service) is a very important concept. QoS parameters include: delay (delay), delay jitter (delayjitter), loss rate (lossrate), bandwidth (bandwidth), etc. Different services will require the network to provide different QoS parameters, of which the most basic is bandwidth. [0003] Broadband networks need to use various QoS mechanisms to achieve the following goals: [0004] 1) For users of different levels, priority is given to ensuring the bandwidth of high-level users. [0005] 2) For users of the same level, ensure that each user enjoys the reserved bandwidth, and the part beyond the reservation is determined whether to discard it according to whether the network has remaining bandwidth. [0006] 3) When the ne...
