Description
Technical field
The present invention relates to the passive optical networks in the communications field, and in particular to a kind of distribution method of dynamic bandwidth and dress
It sets.
Background technique
In recent years, PON (Passive Optical Network, passive optical network) accesses skill as a kind of high speed bandwidth
Art is rapidly developed, and PON system is generally by OLT (Optical Line Terminal, optical line terminal), ODN (Optical
Distribution Network, Optical Distribution Network) and ONU (Optical Network Unit, optical network unit) composition, In
Data are broadcast to all ONU by ODN by down direction, OLT；In up direction, in order to avoid light conflict, then the time-division is used
The mode of multiplexing, each ONU only carry out data transmission in the time slot authorized by OLT, and the assigning process of this time slot is exactly OLT
Dynamic Bandwidth Allocation (DBA, Dynamic Bandwidth Allocation) process.
PON system relevant criterion (such as GPON standard ITU-T G.984.3, XGPON standard ITU-T G.987.3
G.989.3 with NGPON2 standard ITU-T in), DBA algorithm mathematics model is described in detail, and bandwidth is divided into following
Several types, respectively fixed-bandwidth RF(Fixed bandwidth), guarantee bandwidth RAIt (Assured bandwidth) and mends
It fills bandwidth (Additional bandwidth), supplement bandwidth can be non-assured bandwidth RNA(Non-assured
) or the bandwidth R that does one's best bandwidthBE(Best-effort bandwidth), wherein fixed-bandwidth RFWith guarantee bandwidth RA
Distribution it is fairly simple, be no more than maximum bandwidth RMUnder the premise of (Maximum bandwidth), directly according to fixed-bandwidth
RFWith guarantee bandwidth RAIt is allocated, for supplementing the distribution of bandwidth, carries out in the following way:
Non-assured bandwidth (RNA), i-th of ONU carries out Dynamic Bandwidth Allocation according to formula (a) in t moment
Bandwidth of doing one's best (RBE), i-th of ONU carries out Dynamic Bandwidth Allocation according to formula (b) in t moment
In actual business scenario, RF、RAAnd RMGenerally it is fixed and invariable, it therefore, can from above-mentioned formula (a) and (b)

Currently practical flow is not related.This DBA algorithm model is applicable, the PON of current business for general business model
System is also mostly based on the DBA algorithm, but the DBA algorithm has the following deficiencies:
(1) when ONU uplink traffic increases suddenly, biggish uplink service can be brought to postpone, in some instances it may even be possible to will cause and lose
Packet.The defect was determined by the characteristics of PON system, i.e., at the time of ONU upstream data response OLT issues bandwidth with OLT band
Be at the time of width issues there are certain delay, this delay be usually several downlinks DBA calculating cycle (such as
250us), that is to say, that the bandwidth that OLT distributes to ONU is the bandwidth needed before several DBA calculating cycles of ONU, rather than
The bandwidth that current time needs, therefore, this will lead to ONU when uplink traffic increases suddenly, can not obtain required bandwidth in time,
To bring uplink service to postpone, in some instances it may even be possible to will cause packet loss；
(2) when ONU uplink traffic is reduced suddenly, it will cause bandwidth waste.As described in disadvantage (1), OLT distributes to ONU
Bandwidth be the bandwidth needed before ONU several DBA calculating cycles, rather than the bandwidth that current time needs, this will lead to
The band that ONU is obtained is wider than bandwidth actually required, causes bandwidth waste；
(3) it if existing simultaneously the uplink traffic increased ONU and ONU of the unexpected reduction of uplink traffic suddenly, can lead
Cause the increased ONU of uplink traffic that can not obtain required bandwidth in time, and the ONU of the unexpected reduction of uplink traffic has occupied and does not need
Bandwidth, to reduce the handling capacity and QOS (Quality of Service, service quality) of entire PON system.
