Abstract
Systems, methods, and computer-readable media for improving the reliability of service function (SF) application in a service function chain (SFC) are provided. In some aspects, the subject technology facilitates automatic service function type validation by a service function forwarder (SFF), for example, by using a probe configured query a function type of a SF module associated with the validating SFF.
Claims20
A method for validating a service function type on a service function (SF) module, the method comprising:
- initiating a probe, at a service function forwarder (SFF), wherein the probe is configured to query a function type of a corresponding SF module;
- receiving a reply from the corresponding SF module in response to the probe;
- validating, at the SFF, the function type of the corresponding SF module based on the reply;
- and
- determining, at the SFF, whether to permit packet forwarding, based on the function type of the corresponding SF module.
A service function type validation system comprising:
- at least one processor;
- and
- a memory device storing instructions that, when executed by the at least one processor, cause the validation system to:
- initiate a probe, at a service function forwarder (SFF), wherein the probe is configured to query a function type of a corresponding SF module;
- receive a reply from the corresponding SF module in response to the probe;
- validate, at the SFF, the function type of the corresponding SF module based on the reply;
- and
- determine, at the SFF, whether to permit packet forwarding, based on the function type of the corresponding SF module.
A non-transitory computer-readable storage medium comprising instructions stored therein, which when executed by one or more processors, cause the processors to perform operations comprising:
- initiating a probe, at a service function forwarder (SFF), wherein the probe is configured to query a function type of a corresponding SF module;
- receiving a reply from the corresponding SF module in response to the probe;
- validating, at the SFF, the function type of the corresponding SF module based on the reply;
- and
- determining, at the SFF, whether to permit packet forwarding, based on the function type of the corresponding SF module.
