Achieving resource management within a network processing unit (NPU) can be challenging due to the NPU's fixed and limited instruction set. In the case of large mobile networks, contexts are dynamic, and each subscriber in the network consumes multiple hardware resources, where a central processing unit (CPU) is typically employed to program individual resources even though generally impractical in high-session rates. To avoid programming individual resources, an example embodiment of the present invention creates a group of resources depending on a category, the group being shared dynamically among subscribers when a subscriber is active in the network. The example embodiment may include a network service processor (NSP) located in a forwarding path, such that the NPU may operate in connection with the NSP to allocate NPU resources using a packetized interface. The example embodiment achieves resource management within the NPU without a host CPU's involvement and without statically delaying resources.
