Detecting and preventing network slice failure for 5g or other next generation network

Abstract

Network slicing can provide logical network partitioning. This introduces a high degree of flexibility to support devices with different requirements in terms of quality of service, as well as to optimize the network usage. However, each one of these networks can be used for distinct business purposes. Thus, individual slice surveillance statistics, including failure messages, can be utilized to alert other slices that share the same infrastructure. Thus, an early recovery action can be prompted based on a single slice's anomalies being shared with other slices.

What is claimed is: 
     
         1 . A method, comprising:
 in response to determining that a failure of a first network slice is caused by a portion of a first physical infrastructure, wherein the first physical infrastructure is shared with a second network slice, predicting, by software-defined networking equipment comprising a processor, that the second network slice is threshold likely to fail; and   based on the predicting and prior to the second network slice failing, migrating, by the software-defined networking equipment, the second network slice to a second physical infrastructure different from the first physical infrastructure to prevent the second network slice from failing.   
     
     
         2 . The method of  claim 1 , further comprising migrating, by the software-defined networking equipment, the first network slice to the second physical infrastructure.

 in response to determining that a first failure of a first network slice is caused by a first physical infrastructure, wherein the first physical infrastructure is shared with a second network slice, predicting that a second failure of the second network slice is going to occur; and 
 based on the predicting and prior to the second failure, migrating the second network slice to a second physical infrastructure different from the first physical infrastructure to prevent the second failure of the second network slice. 
   
     
     
         9 . The software-defined networking equipment of  claim 8 , wherein the operations further comprise migrating the first network slice to the second physical infrastructure.
