Abstract: In some examples, a method includes constructing, by a computing device, a plurality of expressions using a generic query language that is independent of implementation of an associated data store, the associated data store supporting a plurality of operands comprising at least one comparison operand and multiple logical operands; generating, by the computing device, a single query including the plurality of expressions to the associated data store, wherein the plurality of expressions are connected using the multiple logical operands; transmitting, by the computing device, the single query to the associated data store; and receiving, by the computing device, a single set of results corresponding to the single query.

Abstract: Disclosed is a method, system, and computer readable medium to provide an implementation to provide proxy style support for multiple virtual routing and forwarding (VRF) instances on a single network communication device. The proxy style support includes instantiating a plurality of pairs of namespaces and instances of a Unix service, each of the plurality of pairs representing a pair to support a single instance of a VRF. The network communication device may receive a network request associated with a network address mapped to a first VRF from a client device. The network request may be proxied from the pair of namespace/service supporting the first VRF to a backend single instance of a proxy server. Communication across independent namespaces may be supported by using a local communication mechanism (e.g., Unix sockets, Winsock) to provide support for the multiple VRFs concurrently.
