Therefore, send the network configuration protocol message by generation and to managed device in the present embodiment, in carrying one deck at least in operand information, remote procedure call layer and the transport layer, this network configuration protocol content of message layer carries operation context, because the content-form of the content layer operand information of carrying can relative fixed, so when helping being implemented in many examples of supporting business, the stability that keeps the basic business interface, make that also reusing the basic business interface becomes feasible, helps the simplified system complexity.
Embodiment two
For ease of better understanding the technical scheme of the embodiment of the invention, mainly the RPC layer of Netconf protocol massages is expanded in the present embodiment with Network Management Equipment, mainly the ad-hoc location at Netconf protocol massages RPC layer carries operation context, carry operand information at the Content layer, to be example, carry out further detailed description to the accurate assigned operation object of network element A (managed device), operating environment.
Can comprise referring to Fig. 2, concrete steps:
201, Network Management Equipment generates the Netconf protocol massages, and wherein, the RPC layer of this Netconf protocol massages carries operation context, the Content layer carries operand information.
Wherein, for example work as Network Management Equipment and need (for example carry out certain operation managed device, dispose certain parameter of certain parameter, inquiry managed device etc. for managed device) time, Network Management Equipment can generate the network configuration protocol message, carry operand at this network configuration protocol content of message layer, carry operation context in one deck at least in remote procedure call layer and the transport layer, wherein, this operation context can be specified the scope of the operand of operations such as for example disposing of will carrying out, inquiry, and/or, the system operational parameters that assigned operation relies on etc.
Wherein, network element A can be as various network elements such as base station, Mobility Management Entity, gateways.
In the present embodiment, Network Management Equipment is expanded the RPC layer of Netconf protocol massages, Network Management Equipment for example can carry operation context (one or more) at the ad-hoc location (this ad-hoc location is by Network Management Equipment and network element A arbitary convention) of the RPC of Netconf protocol massages layer.And the content format of the operation context that the RPC layer of Netconf protocol massages carries also can be by Network Management Equipment and network element A arbitary convention, can identify the operation context that the RPC layer of Netconf protocol massages carries to guarantee network element A.
Under a kind of application scenarios, Network Management Equipment can carry one or more operation context at the RPC of Netconf protocol massages layer, it can be whole operation context that this network configuration protocol message carries, or also may be the part operation context (for example, Network Management Equipment also carries another part operation context at the operation layer of this network configuration protocol message) that this network configuration protocol message carries.
When practical application, the content format of the operand that the content layer of Netconf protocol massages carries can remain relative fixed, does not promptly generally change, and so just helps guaranteeing that the basic business interface is relatively stable; And the operation context that the RPC layer of Netconf protocol massages carries, be used to specify the scope of the operand that the content layer to this Netconf protocol massages carries, and/or, the system operational parameters that assigned operation relies on, this operation context may present different-format under the different application scene, if but carry this operation context at the ad-hoc location of the RPC of Netconf protocol massages layer, managed device still can identify this operation context from this Netconf protocol massages parsing by fixing pattern.For instance, when the business nesting level changes (for example network element A comprises a plurality of VR examples), Network Management Equipment utilizes the information assigned operation object (for example inquiring about the routing table under certain VR example) of content of operation layer, utilize the scope (parent object, i.e. this VR example) of operation context assigned operation object; And network element A resolves this Netconf protocol massages after receiving the Netconf protocol massages, just can identify the Content layer by the basic business interface and carry operand; And content format according to a preconcerted arrangement, identify this operation context that the ad-hoc location of RPC layer carries, and then obtain the accurate information of this operation.Can find, in this implementation,, also can not need to revise the basic business interface and can finish mutual between webmaster and managed device even the business nesting level changes (being professional many examples).
202, Network Management Equipment sends this network configuration protocol message to network element A.
Wherein, Network Management Equipment for example can utilize the carrying of IP bag to send this network configuration protocol message.
203, network element A receives and resolves this Netconf protocol massages, identifies the operand that operation context that the RPC layer of this Netconf protocol massages carries and Content layer carry, and carries out corresponding operation according to identifying operation context and operand.
Wherein, network element A can carry out the corresponding configuration of for example modification according to identifying operation context, or feeds back the operations such as response message of carrying corresponding information to Network Management Equipment.
For instance, if Network Management Equipment is the routing table that will inquire about the Virtual NE a1 under the network element A, then network element A can carry the response message of the routing table of Virtual NE a1 to the Network Management Equipment feedback.
Can find, Network Management Equipment is by generating and sending the network configuration protocol message to network element A, carry operand information at this network configuration protocol content of message layer, carry operation context in the RPC layer, because the content-form of the content layer operand information of carrying can relative fixed, be carried at the RPC layer and be used to indicate because of the multi-service exemplary application causes the operation context of the operand scope that may change, so when helping being implemented in the many example of supporting business, the stability that keeps the basic business interface, make that also reusing the basic business interface becomes feasible, helps the simplified system complexity.
Carry out more specific description below by several examples.
For example the RPC layer of Network Management Equipment expansion Netconf protocol massages is expanded one or more attribute fields that are used to carry operation context in the rpc label of the RPC of Netconf message layer.
For example the name of Kuo Zhan attribute field is called context, and then the structure of the Netconf protocol massages after the expansion of Network Management Equipment generation can be as follows:
<rpc?message-id＝“101”
xmlns＝“urn:ietf:params:xml:ns:netconf:base:1.0”
context＝“context?info”>
<some-method>
<！--method?parameters?here...-->
</some-method>
</rpc>
Wherein, " context info " fills in operation context information, and the content of other parts can be the form of standard definition.The signal that the value of above-mentioned message-id, xmlns is just given for the integrality of example message, its value does not have special implication.
For example network element A is a router, comprised a plurality of virtual route examples under the network element A, and the virtual route instance identification (vrfName) that Network Management Equipment need be inquired about under the network element A is the routing table of vrf100, and then the message that generates and sends of Network Management Equipment can be as follows:
<rpc?message-id＝″101″
xmlns＝″urn:ietf:params:xml:ns:netconf:base:1.0″
Context=" vrfName=vrf100 "〉* expands an attribute field *
<get-config>
<source>
<running/>
</source>
<filter?type＝″subtree″>
<top?xmlns＝″http://example.com/schema/1.2/config″>
＜routeTable/〉the operand * that carries of * content layer
</top>
</filter>
</get-config>
</rpc>
The response message that network element A generates and replys can be as follows:
<rpc-reply?message-id＝″101″
xmlns＝″urn:ietf:params:xml:ns:netconf:base:1.0″
context＝“vrfName＝vrf100”>
<data>
<top?xmlns＝″http://example.com/schema/1.2/config″>
<routeTable>
<route>
<destination>101.0.0.0</destination>
<mask>24</mask>
<nextHop>101.0.0.1</nextHop>
<interface>Ethernet1/0/0</interface>
</route>
<route>
<destination>101.0.0.1</destination>
<mask>32</mask>
<nextHop>127.0.0.1</nextHop>
<interface>InLoopBack0</interface>
</route>
<route>
<destination>102.0.0.0</destination>
<mask>24</mask>
<nextHop>102.0.0.1</nextHop>
<interface>Ethernet2/0/0</interface>
</route>
</routeTable>
</top>
</data>
</rpc-reply>
In addition, sometimes has the demand of carrying a plurality of operation context, Network Management Equipment is expanded a plurality of attribute fields that are used to carry operation context in the rpc label of the RPC of Netconf message layer, perhaps, carry a plurality of operation context in an attribute field that expands.
Wherein, for example network element A is the routing forwarding device, comprises a plurality of virtual route examples under the network element A, and Network Management Equipment is wanted to inquire about under the network element A virtual route example vrId and is 1, vrfName is the routing table of vrf100, and then the message that generates and sends of Network Management Equipment can be as follows:
(1) expand a plurality of attribute fields at the rpc label:
<rpc?message-id＝″101″
xmlns＝″urn:ietf:params:xml:ns:netconf:base:1.0″
VrId=" 1 " vrfName=" vrf100 "〉* expands two attribute field *
<get-config>
<source>
<running/>
</source>
<filter?type＝″subtree″>
<top?xmlns＝″http://example.com/schema/1.2/config″>
＜routeTable/〉the operand * that carries of * content layer
</top>
</filter>
</get-config>
</rpc>
(2) in the value of an attribute field, carry a plurality of operation context:
<rpc?message-id＝″101″
xmlns＝″urn:ietf:params:xml:ns:netconf:base:1.0″
Context=" vrId=1, vrfName=vrf100 "〉* expands an attribute field *
get-config>
<source>
<running/>
</source>
<filter?type＝″subtree″>
<top?xmlns＝″http://example.com/schema/1.2/config″>
＜routeTable/〉the operand * that carries of * content layer
</top>
</filter>
</get-config>
</rpc>
At this moment, the response message that network element A generates and replys can be analogized, and repeats no more herein.
Can find, in above-mentioned implementation,, also can not need to revise the basic business interface and can finish mutual between webmaster and the network element A even the business nesting level changes.
Be appreciated that above-mentioned example is to carry one or more operation context with the one or more fields of expansion in the rpc of RPC layer label to be illustrated, one or more operation context are carried in other position that can certainly be chosen in the RPC layer.
In actual applications,, can also obtain other different execution mode, for example carry one or more operation context at Operations layer, Transport Protocol layer by changing operation context in the position of carrying of Netconf protocol massages.
Therefore, send the Netconf protocol massages by generation and to managed device in the present embodiment, carry in operand information, the RPC layer at the content layer of this Netconf protocol massages and to carry operation context, because the form of operand information can relative fixed, so when helping being implemented in the many example of supporting business, the stability that keeps the basic business interface makes that also reusing the basic business interface becomes feasible, helps the simplified system complexity.
