Abstract: A system for configuration management using OVSDB protocol. The system includes a configuration manager on a server computer and a plurality of devices on a plurality of computing devices. The configuration manager comprises an OVSDB server maintaining an OVSDB database. Each of the plurality of devices includes an OVSDB client. The OVSDB database on the configuration manager comprises a database schema containing configuration data for the plurality of devices. The OVSDB server on the configuration manager communicates with the OVSDB client on each of the plurality of devices via OVSDB protocol in managing configurations of the plurality of devices.

Abstract: A non-transitory computer-readable medium having a program stored thereon that, when executed by one or more processors, directs a computing system to secure a communication network. The program comprises a traffic inspection engine, a domain generation algorithm (DGA) inspection engine, and a message bus communicationally coupling the traffic inspection engine and the DGA inspection engine. The traffic inspection engine is configured to identify if a traffic session containing a domain name system (DNS) request and/or response in a communication network includes a DGA generated domain and send information about the identified DGA generated domain to the DGA inspection engine via the message bus. The DGA inspection engine is configured to verify if the identified DGA generated domain is registered, and send information about the registered DGA domain to the traffic inspection engine via the message bus.

Abstract: A computer-implemented method includes generating a hash key using a number of least significant bits (LSBs) for indexing an indirection table in a computing system including multiple processing cores. In generating the hash key, symmetry constraints for a request packet and a response packet through a same communication channel are computed. The symmetry constraints include at least a condition where the LSBs of a hash value corresponding to a source or destination IP address of the request packet are equal to the LSBs of a hash value corresponding to a destination or source IP address of the response packet, wherein the LSBs of the hash value of the request and response packets are of a number same as the number of LSBs used for indexing the indirection table. A string of bits are subjected to the symmetry constraints and adjusted to satisfy the symmetry constraints to generate the hash key.
