Description
Technical field
The present invention relates to the communications field, in particular to the side that message interaction is carried out between veneer in a kind of network equipment
Method and the network equipment.
Background technology
From the birth of the last century 70's internet so far, internet experienced snafu development, and form mutual
The various network equipments of networking, its implementation also experienced huge change, for example as the nucleus equipment of internet ---
Router, multiple developing stage are just experienced, wherein first generation router is to plug polylith NIC on computers
To realize, be connected between polylith interface card and the processor of computer by internal bus, processor is responsible for all issued transactions,
It is real on one processor due to various functions all being concentrated including equipment control, procotol processing, data forwarding etc.
It is existing, therefore forward efficiency is relatively low.Modern medium-and-large-sized router all uses distributed structure/architecture substantially, be the characteristics of this framework by
The routing forwarding task higher to performance requirement realized by special board, and at the procotol slightly lower to performance requirement
The tasks such as reason, plant maintenance are also realized using special board, because procotol processing and plant maintenance etc. belong to for number
According to control and equipment the control in itself of forwarding behavior, so referred to as control plane (Control Plane), and data forwarding
Flow is that the information obtained according to control plane carries out simple and quick forwarding, therefore referred to as datum plane (Data
Plane), so it is that control plane separates with datum plane that this distributed structure/architecture, which is also referred to as, used by modern router
Framework.
In fact, due to control plane and the reasonability of datum plane separation architecture, in the network equipment in modern times, except road
Outside device, other network equipments, such as the catenet equipment such as core net, access network in interchanger, or communication network
All use this framework.Such as, it is specified that two data transmission interfaces, one be called basic interface in the ATCA specifications of standard
(Base Interface), one is called Fabric Interface (Fabric Interface).Basic interface provides base in ATCA cabinets
This IP transmission, Fabric Interface is the high speed data transmission interface in ATCA cabinets, and the two coffrets correspond respectively to control
Plane processed and datum plane.
Generally it is made up of in distributed network equipment the different veneer of polylith, these veneers undertake task not according to it
With three major types are divided into, the first kind is control plane veneer (Control Plane Board, referred to as CPB), and the second class is data
Plane veneer (Data Plane Board, referred to as DPB), the 3rd class are responsible for data exchange between device interior difference veneer
Power board.For example in 3G core nets or access net system equipment, control plane veneer includes：Special disposal Routing Protocol
Routing Protocol process plate (Route Process Board), exclusively carry out the signaling processing plate (Signal of signaling processing
Process Board), and it is responsible for master control process plate (the Operation and Maintain of system operation maintenance specially
Process Board) etc.；Datum plane veneer includes：It is responsible for the interface board of message access specially, is responsible for specially handling 3G subscription
User plane protocol process plate of face agreement etc.；Power board includes control plane power board and datum plane power board, is each responsible for
The exchange of control plane message and the exchange of datum plane message.Fig. 1 is a framework of typical distributed network equipment
Schematic diagram, the two control plane veneers (signaling processing plate A and signaling processing plate B) for forming the equipment and two are depicted in figure
Datum plane veneer (interface board A and interface board B), and (control plane power board and datum plane exchange two power boards
Plate), and the connection of each piece of veneer in equipment is illustrated with hollow four-headed arrow, illustrate different reports with hollow unidirectional arrow
Flow direction of the text in device interior.
In order to obtain higher datum plane performance, datum plane veneer is usually using special processor, for example uses
Network processing unit or the polycaryon processor with network acceleration characteristic.By taking the veneer using network processing unit as an example, at network
The micro engine of reason device is responsible for completing the high speed forward processing of data；And general-purpose processor core that network processing unit is internally integrated or
The plug-in general processor of person, then complete the loading of network processor micro-engine execute instruction, the configuration of various forwarding rules, property
Can statistics collection and the task such as report.Therefore, the responsibility that is undertaken according to each several part inside datum plane veneer is drawn
Point, datum plane veneer can have been divided to two component units：One be network processing unit micro engine, they are responsible for message
Fast-forwarding processing, the unit that we will be responsible for this part of functions is referred to as datum plane processing unit (Data Plane
Process Unit, referred to as DPPU)；Another is the general-purpose processor core that network processing unit is internally integrated or plug-in
General processor, due to they to complete micro engine instruction loading, forwarding rule configuration, performance statistic collection with
The task such as report, be required for control plane single plate interactive, belong to the processing of control plane, therefore we will be responsible for this part
The unit of function is referred to as control plane processing unit (Control Plane Process Unit, referred to as CPPU).
In distributed network equipment, interface board is a kind of typical datum plane veneer, and interface board is responsible for connecing for message
Receive, and forward the packet to corresponding process plate.Because device interior control plane separates with datum plane, therefore some equipment
Interface board with two kinds of difference in functionalitys, control plane interface board and data plane interface plate, wherein the former and device interior control
Plane power board processed is connected, and is responsible for receiving the message of control plane, and the datum plane power board of the latter and device interior specially
It is connected, is responsible for receiving the message of datum plane specially.In view of the convenience and cost factor of networking, current many equipment are
Through realizing control plane and datum plane common network mouth function, i.e. control plane interface board closes with datum plane interface board function
One, the message received is distributed to different veneers and handled by the interface board needs after unification, if the purpose list of message
Plate is datum plane veneer, then message is directly sent to datum plane power board by the DPPU of interface board, is exchanged by datum plane
Plate represents MESSAGE EXCHANGE to purpose veneer, the in Fig. 1 handling process of this message with the dotted line of arrow.If the mesh of message
Veneer be control plane veneer, then because the DPPU of interface board is not connected, it is necessary to first pass through with control plane power board
Plate internal channel gives message the CPPU of this plate, then message is sent into control plane power board by the CPPU of this plate, then by it
By MESSAGE EXCHANGE to purpose veneer；If control plane veneer needs to send a message to device external, it can only pass through
Message is first sent to the CPPU of interface board by control plane power board, and the CPPU of interface board will be reported by the data channel in plate
Text issues its DPPU, then message is sent into device external by DPPU, and the handling process of both messages is with the arrow in Fig. 1
Solid line represents.For the ease of understanding and the contrast with the present invention, Fig. 2 gives when receiving different messages outside interface board slave unit
Handling process.
In order to ensure between different control plane veneers and the CPPU of control plane veneer and datum plane veneer between lead to
The reliability of letter, it is reliable usually using RUDP (RUDP), TIPC (transparent interprocess communication) etc. in system
Transport layer communication protocol, and the data that will be transmitted are packaged into message between different boards, therefore put down in control plane veneer and data
Can all there is a message between different boards processing unit on the CPPU of face veneer, be responsible for receiving and sending message between different boards.This machine manufacture
Data communication into control plane is larger for system resource occupancy, and due to the reasons such as cost and power consumption, datum plane
The CPPU of veneer performance is weaker, when datum plane veneer needs on send control plane veneer message amount it is more when, easily
Cause its CPPU load heavier, cause the generation that its response speed is slack-off, message delay is big, even loses situations such as message.
In fact such message is mainly handled by control plane veneer, and the CPPU of interface board is only responsible for the transfer of message, also
It is to say that it is a simple communication port, as a simple communication port, transfer control plane message provides to it
The consumption in source is obviously excessive；On the other hand, control plane veneer is received by the message between different boards processing unit run thereon in itself
The message that the veneer distribution of hair datum plane comes, it is also bigger to the expense of its resource；3rd, the CPPU connections control of datum plane
The bandwidth of the passage of plane power board processed is limited, and control plane veneer is given when datum plane veneer needs to distribute more message
When, the valuable bandwidth of the communication port of its CPPU connection control plane power board can be taken, influences the transmitting-receiving of critical message.
For the above mentioned problem in correlation technique, effective solution is not yet proposed at present.
