In in order to realize the scheduling of channel resource switch, the dynamic channel resource switch module should support warm reset and switching work(
Energy.
Further, it is contemplated that the problem of making full use of bandwidth and preferably ensureing data transmission quality.It is of the invention real
Apply in example, the dynamic channel resource switch module is additionally operable to：The data that multiplex data delivery module will be passed to are carried out pre-
Processing, the pretreatment operation include：Data traffic types and channel number are marked, complete QoS (Quality of
Service, service quality) processing, complete WRED (Weighted Random Early Detection, Weighted random are examined in advance
Survey) processing, complete OAM (Operation Administration and Maintenance, operation, management, safeguard) processing
Deng.
Multiplex data delivery module is used for：The data forwarding control signal generated according to main control module, utilize the logical of foundation
Road connection obtains data from TDM business datums caching or grouping busihess data caching, and the data cross got is forwarded
To back-end system side.
Shown in Figure 2, the embodiment of the present invention also provides a kind of realizes TDM and Packet Service dynamic based on said apparatus
The method of multiplexing transmission, comprises the following steps：
Step S1, main control module parsing user configuration information, the type of service generation passage in user configuration information
Configuration and switch-over control signal, segment data cache control signal and data forwarding control signal.
Step S2, the passage configuration and switch-over control signal that dynamic channel resource switch module generates according to main control module are entered
The configuration and scheduling switching of row of channels resource, make type of service and segment data of the multiplex data delivery module according to user configuration
TDM business datums caching or grouping busihess data caching in cache module establish passage connection.
As shown in figure 3, in one embodiment, step S2 specifically includes below scheme：
Step S201, the passage configuration of dynamic channel resource switch module parsing main control module generation and switching control letter
Number, get the type of service of user configuration.
Step S202, by the type of service of user configuration compared with current channel resource type, judge that both are
It is no consistent, if so, being transferred to step S203；Otherwise, it is transferred to step S204.It is understood that channel resource type is divided into TDM industry
Business resource type, Packet Service resource type；The channel resource type of acquiescence is TDM service resources types, that is, the passage given tacit consent to
Resource is used for TDM operation transmission, that is to say, that multiplex data delivery module is and the TDM business in segment data cache module
Data buffer storage establishes passage connection.
Step S203, dynamic channel resource switch module does not perform scheduling switching action, keeps multiplex data delivery module
Cached according to the TDM business datums caching in current channel resource type and segment data cache module or grouping busihess data
Establish passage connection.
For example, if the type of service of user configuration is TDM business, current channel resource type is the TDM of acquiescence
Service resources type, both are consistent, then dynamic channel resource switch module does not perform scheduling switching action, will keep multiplex data
Delivery module is established passage with the TDM business datums caching in segment data cache module and is connected.
Step S204, dynamic channel resource switch module performs scheduling switching action, and current channel resource type is matched somebody with somebody
The type of service of user configuration is set to, and multiplex data delivery module is switched to type of service and segmentation according to user configuration
TDM business datums caching or grouping busihess data caching in data cache module establish passage connection.
For example, if the type of service of user configuration is Packet Service, current channel resource type is the TDM of acquiescence
Service resources type, both are inconsistent, then dynamic channel resource switch module will perform and dispatch switching action, by current passage
Resource type is configured to Packet Service, and multiplex data delivery module is switched to and the packet industry in segment data cache module
Business data buffer storage establishes passage connection.In practical operation, multiplex data delivery module is switched to and segment data cache module
In grouping busihess data caching when establishing passage connection, can first disconnect multiplex data delivery module and TDM business datums and cache
Passage connection；Resettle multiplex data delivery module and be connected with the passage that grouping busihess data caches.
Step S3, the segment data cache control signal that receiving module generates according to main control module is to front-end customer side data
Handled；And the data after processing are sent to segment data cache module；Segment data cache module is according to front-end customer
Data storage after the type of service of side data handles receiving module caches or Packet Service number to corresponding TDM business datums
According in caching.
Step S4：The data forwarding control signal that multiplex data delivery module generates according to main control module, using currently building
Vertical passage connection obtains data from TDM business datums caching or grouping busihess data caching；And the data got are handed over
Fork is forwarded to back-end system side, and the backboard or business single-deck of system side will be further processed to data.
It by aforesaid operations, can realize that TDM and Packet Service share a set of transfer resource in single board, that is, share and divide
The capacity of segment data cache module.When the timing of capacity one of segment data cache module, its internal TDM business datums caching and
The division of grouping busihess data caching, can be adjusted according to practical business demand.Such as 100G boards, it is configured with dividing for 100G
The capacity of segment data cache module, then according to practical business demand can actual division for 10G TDM business and 90G packet
Business or 50G TDM business and 50G Packet Service, under limiting condition can actual division be used for convergence 100G TDM business
With convergence 0G Packet Service or convergence 0G TDM business and convergence 100G Packet Service.So allow for designer
The channel resource (data buffer storage of such as double capacity) of double bandwidth is no longer needed to use when designing line card, it is possible to realize
TDM and Packet Service mixed transport, save line card resource, reduce cost, at the same also ensure single-deck form variation and
Flexibility.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
On the premise of the principle of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as the protection of the present invention
Within the scope of.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
