Abstract
Methods and systems for exporting network information from an exporter to a collector are disclosed. Embodiments of the present technology may include updating a non-key field of a flow entry in a flow cache that corresponds to a flow, setting a field in a context-bitmap of the flow entry in response to updating the non-key field of the flow entry, identifying an export policy using the context-bitmap, and exporting information related to the flow to a collector according to the export policy.
Claims19
A method for exporting network information from an exporter to a collector, the method comprising:
- updating a non-key field of a flow entry in a flow cache that corresponds to a flow;
- setting a field in a context-bitmap of the flow entry in response to updating the non-key field of the flow entry;
- and
- identifying an export policy using the context-bitmap;
- and
- exporting information related to the flow to a collector according to the export policy.
A method for exporting network information from an exporter to a collector, the method comprising:
- updating a non-key field of a flow entry in a flow cache that corresponds to a flow;
- setting a field in a context-bitmap of the flow entry in response to updating the non-key field of the flow entry;
- and
- identifying an export policy using the context-bitmap;
- and
- exporting information related to the flow to a collector according to the export policy, wherein exporting information related to the flow to a collector according to the export policy involves exporting information according to the Internet Protocol Flow Information eXport (IPFIX) protocol;
- wherein the non-key field in the flow cache holds information related to the flow and a bit in the context-bitmap includes a context bit that is set in response to a value of the non-key field.
A system for exporting network information from an exporter to a collector, the system comprising:
- a processor;
- and
- a computer readable medium that stored instructions, which when executed by the processor, implement:
- updating a non-key field of a flow entry in a flow cache that corresponds to a flow;
- setting a field in a context-bitmap of the flow entry in response to updating the non-key field of the flow entry;
- identifying an export policy using the context-bitmap;
- and
- exporting information related to the flow to a collector according to the export policy.
