Abstract
Disclosed is a method for continuous in-line monitoring of data-centric traffic to guarantee application performance. The method includes, in each switch of a plurality of switches in a network fabric, grouping all packets entering each respective switch of the plurality of switches based on either 5-tuple applications or EPG based applications, collecting performance statistics at every hop in the network fabric across all flows in-line in a flow table maintained in each respective switch and periodically exporting the performance statistics to analysis module.
Claims20
A method comprising:
- grouping packets entering each switch of a plurality of switches in a network fabric;
- collecting performance statistics at hops in the network fabric across flows in-line in a flow table maintained at each switch;
- and
- exporting the performance statistics to an analysis module.
A system comprising:
- at least one processor;
- and
- at least one memory, storing instructions, which when executed by the at least one processor, causes the at least one processor to:
- group packets entering each switch of a plurality of switches in a network fabric;
- collect performance statistics at hops in the network fabric across flows in-line in a flow table maintained at each switch;
- and
- export the performance statistics to an analysis module.
At least one non-transitory computer-readable medium, storing instructions, which when executed by at least one processor, causes the at least one processor to:
- group packets entering each switch of a plurality of switches in a network fabric;
- collect performance statistics at hops in the network fabric across flows in-line in a flow table maintained at each switch;
- and
- export the performance statistics to an analysis module.
