Abstract

Systems, methods, and computer-readable media for providing cross-domain assurance for networks in different network domains. In some embodiments, a method can include collecting first fabric data for a first network in a first network domain and second fabric data for a second network in a second network domain. The second fabric data for the second network can be normalized based on the first network domain to create normalized second fabric data. The first fabric data can then be correlated with the normalized second fabric data to create correlated fabric data. Subsequently, assurance can be provided across the first network in the first network domain and the second network in the second network domain using the correlated fabric data.

Claims20

Dependent claims

A method, comprising:

collecting fabric data across a plurality of network domains, wherein the fabric data indicates one or more policies implemented in corresponding network domains of the plurality of network domains;
translating at least a portion of the fabric data from at least one of the plurality of network domains into a form that is compatible with another portion of the fabric data from at least another of the plurality of network domains to create translated fabric data;
correlating the fabric data, including at least the portion of the fabric data from at least one of the plurality of network domains and the another portion of the fabric data from at least another of the plurality of network domains, based at least in part on the translated fabric data to create correlated fabric data;
and
providing policy assurance across the plurality of network domains by determining whether the one or more policies implemented in corresponding network domains of the plurality of network domains are compatible across the plurality of network domains based on the correlated fabric data.

2 more elements

A system comprising:

one or more processors;
and
a computer-readable medium comprising instructions stored therein, which when executed by the one or more processors, cause the one or more processors to:
collect fabric data across a plurality of network domains, wherein the fabric data indicates one or more policies implemented in corresponding network domains of the plurality of network domains;
translate at least a portion of the fabric data from at least one of the plurality of network domains into a form that is compatible with another portion of the fabric data from at least another of the plurality of network domains to create translated fabric data;
correlate the fabric data, including at least the portion of the fabric data from at least one of the plurality of network domains and the another portion of the fabric data from at least another of the plurality of network domains, based at least in part on the translated fabric data to create correlated fabric data;
and
provide policy assurance across the plurality of network domains by determining whether the one or more policies implemented in corresponding network domains of the plurality of network domains are compatible across the plurality of network domains based on the correlated fabric data.

5 more elements

At least one non-transitory computer-readable storage medium comprising instructions stored therein, which when executed by one or more processors, cause the one or more processors to:

collect fabric data across a plurality of network domains, wherein the fabric data indicates one or more policies implemented in corresponding network domains of the plurality of network domains;
translate at least a portion of the fabric data from at least one of the plurality of network domains into a form that is compatible with another portion of the fabric data from at least another of the plurality of network domains to create translated fabric data;
correlate the fabric data, including at least the portion of the fabric data from at least one of the plurality of network domains and the another portion of the fabric data from at least another of the plurality of network domains, based at least in part on the translated fabric data to create correlated fabric data;
and
provide policy assurance across the plurality of network domains by determining whether the one or more policies implemented in corresponding network domains of the plurality of network domains are compatible across the plurality of network domains based on the correlated fabric data.
