Abstract
Techniques described herein improve network security and traffic management. In an embodiment, a request associated with an identifier (ID) is received. It is determined whether the ID exists in a first membership database (MDB). If the ID exists in the first MDB, the request is serviced subject to a rate limit. If the ID does not exist in the first MDB, it is determined whether the ID exists in a second MDB. If the ID exists in the second MDB, the request is serviced. If the ID does not exist in the second MDB, the request is serviced subject to another rate limit. A response is received. The first and second MDBs can be updated based on the type of received response. In an embodiment, the response is classified as indicative of degraded or typical network performance, and the first and second MDBs are updated accordingly.
