Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the present invention, not
For limiting the present invention.
Optical transport network framework and particular technique based on PTN are: IP (Internet Protocol, between network mutually
Agreement even) level is provided between business and bottom light-transmitting medium, it for Packet Service flow sudden and
The requirement of statistic multiplexing transmission and design, as core and support that multi-service provides using Packet Service, with lower TCO (Total
Cost ofOwnership, overall use cost), while the traditional advantage of optical transport is adhered to, including high availability and reliability,
Efficient bandwidth management mechanism and traffic engineering, convenient and fast OAM (OperationAdministration and
Maintenance, Operations, Administration and Maintenance) and network management, expansible, higher safety etc..Fig. 1 is PTN at this stage in net
Positioning schematic diagram in network.
OTN be based on wavelength-division multiplex technique, in the transmission net of light layer tissue network, be follow-on backbone transmission
Net.OTN by G.872, G.709, a series of ITU-T (ITU-T for ITU Telecommunication such as G.798
Standardization Sector, standard branch office of international telecommunication union telecommunication) suggestion standardized a new generation " number transmission
System " and " optical transport hierarchy ".Referring to fig. 2, the positioning of OTN at this stage: 1, OTN is applied to metropolitan area network core layer and convergence layer,
Main carrying SW (switch device) first line of a couplet BRAS (Broadband Remote Access Server, broad band remote access clothes
Be engaged in device) between demand and core engine building, county to GE demand between city machine building.
Traditional networking mode is passed based on SDH (Synchronous Digital Hierarchy, synchronous digital system) etc.
Unite transmission technology, be mainly time-multiplexed interleaved mode using TDM, however, traditional networking mode for FE (Fast Ethernet,
Fast Ethernet), the big band width service of IP class of GE (Gigabit Ethernet, gigabit Ethernet) and larger particle, it may appear that
The problem of converging insufficient layer bandwidth, service bearer low efficiency.
In existing net, often core backbone layer (or referred to as core layer) uses OTN, convergence layer and following use PTN group
Net.Make full use of OTN that first line of a couplet traffic scheduling to the affiliated business of PTN is landed website.In network interworking mode, OTN is not only
A kind of carrying means, also by its to the GE/10GE business of the backbone node first line of a couplet with it is affiliated intersects to land carried out between equipment
The quantity of scheduling, the channel first line of a couplet GE/10GE can be according to the business sum configuration on demand actually accessed in the PTN, thus pole
The earth simplifies the network construction between backbone node and core node, avoids in PTN independence networking mode, because of certain node
The case where all node devices must upgrade on loop caused by volume of business upgrading, dramatically saves network investment.
The embodiment of the present application scheme is mainly the network flow for facing to expand rapidly, gives full play to the respective skill of PTN and OTN
Art advantage, network interworking build high efficiency of transmission network.
