Description
Technical field
The present invention relates to data communications equipment fields, and in particular to a kind of end-to-end QoS ensures implementation method and is
System.
Background technique
In data communication process, network provider is responsible for providing network, and carries various businesses over the network.Network
When provider's bearer service, can certain business be made with service quality promise.The service quality content of promise include CIR,
The indexs such as EIR, time delay, delay variation, packet loss.Correlation function is real usually using Differentiated Services (DiffServ) in the prior art
Existing, at Web portal, the network equipment checks packet content, and carries out classification and marking, all subsequent bands for data packet
Wide guarantee strategies are all made according to the label in data packet.
For the data communications equipment based on rigid tubing technology, such as OTN (optical transfer network, OpticalTransportNetwork),
It can naturally guarantee the bandwidth of network end-to-end；But for the data communications equipment based on group technology, such as PTN (grouping transmission
Net, Packet Transport Network) or router, then lack for the bandwidth safeguard skill in business end-to-end procedure
Art.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of the present invention is to provide end-to-end in a kind of data communications equipment
Quality of service ensures realization method and system, can provide in business end to end transmission process for guaranteeing portions of bandwidth stream
The guarantee of amount.

Specifically, when distinguishing, for MPLS network inside using the Pipe or ShortPipe in RFC 3270
Mode carries out priority mapping；
For network edge node equipment, using srTCM the or trTCM algorithm based on RFC2698, RFC2697, for
Message is tested and assessed, and message is stamped color mark according to evaluating result, by message by color mark divide into green packet,
Yellow packet and red packet.Red packet is then abandoned, by the colouring information of green packet and yellow packet, being encoded to will
The EXP field of outermost layer MPLS label in the message of transmission.
SrTCM or trTCM algorithm based on RFC2698, RFC2697 is the technical knowledge in the field, is clearer explanation
Its principle is described as follows by the present invention program by taking srTCM as an example：
Single-rate three-color marker device (srTCM) can measure IP stream of packets, and be green, yellow or red packet marking
Color.If the grouping reached is less than Committed Burst Size, it labeled as green；Committed Burst Size if more than and
It is less than burst excess size, then it is labeled as yellow；Otherwise, labeled as red.Single-rate three-color marker device can be used in
Carry out regulatory service at Web portal.
There are two types of operating modes for single-rate three-color marker device:Colour blindness mode and sense color pattern.Under colour blindness mode, it is assumed that institute
Some groupings are all un-marked；In the case where feeling color pattern, it is assumed that the grouping of all inputs have been labeled as green, yellow or
It is red.
3 parameters are specified when configuring single-rate three-color marker device：Committed information rate CIR, Committed Burst Size CBS and
Burst excess size EBS.Wherein, CBS and EBS is greater than 0, and should at least be more than or equal to maximum block length.
For convenience, two token buckets are known as C barrels and E barrels, use TcAnd TeIndicate the token quantity in bucket, TcAnd TeInitially
Change and be equal to CBS and EBS, CBS ratio EBS is small.
TcAnd TeIt is updated CIR times within each second, when update follows following rule：
If Tc<CBS, then Tc increases by 1, otherwise
If Te<EBS, then Te increases by 1, otherwise
TcAnd TeDo not increase
Under colour blindness mode, when assessing arrival message (assuming that message size is B), it then follows following rule：
If Tc-B>=0, then message is marked as green, and Tc reduces B, otherwise
If Te-B>=0, then message is marked as yellow, and Te reduces B, otherwise
Message, which is marked as red and Tc and Te, not to be reduced.
The EXP field of S2, intermediary device and second edge node device decoding MPLS message label, EXP is mapped
To internal priority and color；
Queue is arranged according to the internal priority of the mapping in S3, intermediary device and second edge node device, presses
According to the color configuration packet loss thresholding of the mapping, and queue is configured for each priority query and guarantees bandwidth.

Be with place, in the step S3, each queue configuration guarantees bandwidth CIR on each node, queue CIR by network management configuration or
Person's agreement calculates.To ensure that the CIR of all queues can complete preferentially to ensure transmission, queue CIR should be not less than by way of this
The sum of the CIR of all business in queue.Own specifically, being calculated in each queue in the present embodiment using external network management or agreement
The sum of green packet thresholding of business, is allocated as queue CIR numerical value.
Embodiment 6
Shown in Figure 2, the embodiment of the present invention provides a kind of end-to-end QoS guarantee realization system, further limits
Determine intermediary device and realizes the action principle in end-to-end QoS guarantee implementation method of the present invention：
Intermediary device is sequentially completed following functions in the whole process：
1, priority mapping
Intermediary device identifies MPLS message EXP field, and EXP is mapped to internal priority and color；By EXP high
2bit is mapped to internal priority 0-3；EXP is low, and 1bit is mapped as internal color, is mapped as green when being 1, is mapped as Huang when being 0
Color.
This step completes equipment room, and CIR information is transmitted priority-based.
2, queue management
According to priority it is divided into four queues, and the packet loss thresholding that respectively Lv Bao is different with yellow packet setting inside equipment, it is fixed
Adopted Huang packet packet loss thresholding is lower than green packet packet loss thresholding.
3, queue scheduling
Guarantee each queue CIR bandwidth when outlet is dispatched for each priority query precalculated queue CIR.
Through the above steps, the service bandwidth that can be realized under intermediate node congestion situation is inherited.Principle is as follows：
When gate region not congestion, all business can break-through intermediate node, therefore business guarantee bandwidth it is lossless；
When gate region congestion, each priority can guarantee CIR bandwidth, and the bandwidth beyond CIR then need with
Other queues are seized, and message is temporarily stored in respective queue；(EIR is represented) when queue depth is more than yellow packet thresholding, then yellow packet is opened
Begin to abandon, green packet can still occupy caching (representing CIR) at this time, to realize the effect for preferentially losing yellow packet.Due to walking above
Described in rapid 3, each queue can guarantee CIR flow, as long as therefore buffer setting it is reasonable, so that it may guarantee congestion situation
The CIR partial service of this lower queue not packet loss.
It should be understood by those skilled in the art that, embodiments herein can provide as method, system or computer program
Product.Therefore, complete hardware embodiment, complete software embodiment or reality combining software and hardware aspects can be used in the application
