Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of system and cut-in method based on conversion control separated protocol.
Background technology
Usually, an IP network unit (NE:Network Element) is made up of a plurality of entities of isolating in logic, and these logic entities are provided by the as a whole function (as route or IP exchange) that provides jointly.Described network element mainly comprises two kinds: control unit and retransmission unit, and need between control unit and the retransmission unit to isolate.
Be the information exchange of standardization control and Forwarding plane, i.e. ForCES (transmitting control separates) agreement has been released in control unit that standardization is isolated mutually and the information exchange between the retransmission unit.
But ForCES will make control and Forwarding plane obtain technological progress fast under the prerequisite that keeps mutual operation.Also make the scalability of equipment be very easy to obtain, forwarding and control ability can be increased among the NE flexibly, and do not need to carry out large-scale hardware-software upgrading as now, cause business to be affected.
As shown in Figure 1, provided the example of a plate level physical isolation router among the figure, this router has two control boards and a plurality of conversion board, all is connected on the switching network backboard.Wherein, control board is CE (control unit), and the router plate is FE (retransmission unit), and the switching network backboard provides the physical connection of all plates.Can allow the control board A be main CE, control board B is that backup CE provides the redundancy backup ability.For obtaining high reliability, the network board of a redundancy can be arranged also.The target of ForCES agreement is exactly to realize information exchange between each CE and the FE with standard agreement.Like this, from the X of manufacturer, conversion board is from the Y of manufacturer for control board, and both just become possibility at slitless connection work on a frame.
At present, also there is the physical separation of another CE and FE, i.e. other separation of cabinet level.As shown in Figure 2, all CE and FE are cabinets independently physically, connect (as gigabit Ethernet) by local area network (LAN) at a high speed each other.If each CE and FE communicate by operation ForCES each other, will can produce effect as described in Figure 2 equally.
Describe below in conjunction with the concrete application of accompanying drawing ForCES.
Fig. 3 provides the example of a CE and FE function.A given NE can comprise one or more this CE and FE function.Also show the ForCES agreement among the figure and be used to ForCES oneself and giving/from the data packet delivery control messages of control plane.
As shown in Figure 4, the critical piece of NE framework comprises: CE, FE and intraconnection agreement.CE is responsible for as operations such as signaling, protocol processes and management agreement application.Control plane indicates the bag of Forwarding plane to transmit behavior based on handling the information that generates.For example control plane can be transmitted by operating operation, port status, increase or remove a NAT (network address translation) and connect the control realize a FE.
FE can comprise general, also can have special-purpose, such as NAT, fire compartment wall, encapsulation decapsulation etc.In Fig. 4, a NE comprises a CE and two FE.Two FE and a CE need minimum configuration as pre-configured, and this can be finished respectively by FE manager and CE manager.
The ForCES architecture definition parts of ForCESNE, comprise several attached parts.These parts can connect by different topologys for bag processing flexibly.
As shown in Figure 5, comprise among the figure:
The Fp:CE-FE interface;
The Fi:FE-FE interface;
The Fr:CE-CE interface;
Fc:CE Manager and ce interface;
Ff:FE Manager and FE interface;
FI:CE Manager and FE Manager interface;
The Fi/f:FE external interface.
Comprise two kinds of parts among Fig. 5: control assembly CE and forwarding parts FE.The ForCES framework allows NE to comprise the example of a plurality of CE and FE.Each FE comprises one or more physical interface, and physical interface is used for hand and is bundled to outside the NE.Condensing together of these FE interfaces become the external interface of NE.Except external interface, in NE inside, must there be the interconnecting relation of some kinds, make that CE can intercom mutually with FE, FE can be transmitted to bag other FE.
In the framework of the ForCES of reality, for the function of control plane, may finish by the different CE of function of use, the CE that wherein has may be very simple.Still with the router example, the actual framework of router as shown in Figure 6, n FE linked together by switching network, form datum plane, control plane is made up of two chips of control board: one is the CPU that is used for route calculating and signaling, and one is the special-purpose asic chip that is used for equipment control.Equipment control is responsible for controlling the functions such as load instructions of restarting, send code of switching (under the backup instances), facility environment alarm (too high as temperature, humidity is too high, voltage is undesired, the burning voltage on the FE etc.), veneer of switching network and control board.Because these function relative fixed and simple are so realize with ASIC.
In the ForCES in future framework applications, a kind of CE of specialize equipment control also may appear being similar to, this class CE also may be very simple, be a special ASIC chip,, support the agreement that ForCES is complicated like this for this chip, be very difficult, therefore, how this special CE being compatible with in the ForCES framework, is the problem that needs solve.
In addition, in the equipment of the ForCES in future framework, because there has been very mature C E in now a lot of producer, during equipment dilatation afterwards and producer are integrated, number of C E may occur and support the ForCES agreement, the existing mature C E of other can't support the situation of ForCEs agreement.
As shown in Figure 7, CE3 is an existing cabinet before, can finish some specific CE functions, certain specific protocol for example, in the new NE node of setting up, system integrator wishes singly to be that CE3 can't support the ForCES agreement as an independent cabinet with it with entering.Even CE3 can revise, but for some ripe network operating systems, CE made amendment make it can support the ForCES agreement, then need the index word of carrying out bigger, and its Previous System has own privately owned communication mode, very ripe and stable, therefore, this modification may bring very big risk.
Therefore, in sum,, also there is not a kind of method to satisfy at present at above-mentioned two kinds of demands.
