Abstract: A policy server may include a policy parser that is communicably coupled to a configuration database. The policy parser may identify a policy data model in the configuration database associated with a policy. The policy data model may include a policy object expressed in a human-readable format. The policy server may include a policy engine for constructing a dynamic acyclic graph (DAG) representing the policy data model. The policy engine may include a code generation engine for parsing the DAG to generate code in a high-level language. The policy engine may include a compiler for compiling the generated code to generate binaries for implementing the policy. The policy server may include a policy dispatcher for generating a notification to a policy client to dispatch the binaries to at least one subscriber of the policy following the code being compiled. The policy server may asynchronously update the policy for the subscribers.

Abstract: Disclosed herein is a distributed, modular and highly available routing apparatus that is enabled to perform IP, MPLS VPN v4 and v6 services. The routing apparatus comprises a plurality of functional modules selected from the group consisting of a processor, a data storage module, an input/output module, a shared memory, and a network module. Each functional module is driven by a software architecture comprising a TCP/IP stack, a protocol serializer, a protocol de-serializer, an in-memory data store and one or more utility applications. The software architecture is stored partially or completely in the user space of the operating system of the routing apparatus.

Abstract: Systems and methods of the present disclosure are directed to defining a data store format for storing state information related to border-gateway protocol (BGP) routing information base (RIB) entries, BGP Neighbor Tables, intermediate system-intermediate system (IS-IS) adjacencies, Link-State Databases, Interface information, Chassis information, etc in a binary format. A brick data store (BDS) system can define tables, table properties, objects and attributes for an application in the system using configuration files expressed in Java Script Object Notation (JSON). The data format can be uniform across inter-process communication, file and in-memory representation.
