The Network Processing Forum (NPF) has expanded its Interface Management API specification to include support for tunneling and IPv6. The Interface Management Application Programming Interface (API) Implementation Agreement (IA), originally released in September of 2002, provides a uniform programming interface to configure, manage and administer the external network ports of a networking system such as a router or a switch. The API was expanded to include support for additional interfaces including IPv6 logical interface, IPv6 in IPv4 tunnels, and IPv4 and IPv6 tunnel interfaces. The NPF said that establishing standard external port configuration interfaces greatly simplifies the process of incorporating network processing components from multiple silicon vendors and protocol stack vendors, enabling shorter product development cycles and at lower costs.
