Detect impact of network maintenance in software defined infrastructure

Abstract

A system may assist with checking policy impact in a software-defined infrastructure environment. The system's data analysis may enable it to discover and quantify the impact of policies on software-defined infrastructure objects in the same or different layers.

what is claimed: 
     
         1 . An apparatus comprising:
 a processor; and   a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
 obtaining a policy for maintaining a service; 
 parsing the policy to extract a first object; 
 querying for a second object based on the first object; 
 determining workload variables exposed by the first object and the second object; and 
 emulating the service based on the first object, second object, or the workload variables. 
   
     
     
         2 . The apparatus of  claim 1 , the operations further comprising determining configurations variables exposed by the first object and the second object. 
     
     
         3 . The apparatus of  claim 2 , wherein the configuration variables comprise number of serving gateways or number packet of data network gateways. 
     
     
         4 . The apparatus of  claim 2 , wherein the configuration variables comprise type of server or number of central processing units for a virtual machine. 
     
     
         5 . The apparatus of  claim 1 , wherein:
 the first object is a serving gateway, and   the second object is a mobility management entity.   
     
     
         6 . The apparatus of  claim 1 , wherein:
 the first object is a serving gateway, and   the second object is a virtual network function.   
     
     
         7 . The apparatus of  claim 1 , wherein the first object is a serving gateway. 
     
     
         8 . The apparatus of  claim 1 , wherein:
 the first object is a network server, and   the second object is a virtual machine.   
     
     
         9 . The apparatus of  claim 1 , wherein:
 the first object is an evolved packet core, and   the second object is a packet data network gateway.   
     
     
         10 . The apparatus of  claim 1 , wherein:
 the first object is network server, and   the second object is a base station.   
     
     
         11 . The apparatus of  claim 1 , wherein the workload variables comprise request rate of an evolved packet core or number of clients of an evolved packet core. 
     
     
         12 . A system comprising:
 one or more processors; and   memory coupled with the one or more processors, the memory storing executable instructions that when executed by the one or more processors cause the one or more processors to effectuate operations comprising:
 obtaining a policy for maintaining a service; 
 parsing the policy to extract a first object; 
 querying for a second object based on the first object; 
 determining workload variables exposed by the first object and the second object; and 
 emulating the service based on the first object, second object, or the workload variables. 
   
     
     
         13 . The system of  claim 12 , the operations further comprising determining configurations variables exposed by the first object and the second object. 
     
     
         14 . The system of  claim 13 , wherein the configuration variables comprise number of serving gateways or number of packet data network gateways. 
     
     
         15 . The system of  claim 13 , wherein the configuration variables comprise type of server or number of central processing units for a virtual machine. 
     
     
         16 . The system of  claim 12 , wherein:
 the first object is server, and   the second object is a base station.   
     
     
         17 . A computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:
 obtaining a policy for maintaining a service;   parsing the policy to extract a first object;   querying for a second object based on the first object;   determining workload variables exposed by the first object and the second object; and   emulating the service based on the first object, second object, or the workload variables.   
     
     
         18 . The computer readable storage medium of  claim 17 , the operations further comprising determining configurations variables exposed by the first object and the second object. 
     
     
         19 . The computer readable storage medium of  claim 18 , wherein the configuration variables comprise number of serving gateways. 
     
     
         20 . The computer readable storage medium of  claim 18 , wherein the configuration variables comprise number of central processing units for a virtual machine.
