Abstract: A link list processing apparatus has a storage device and a link list controller. The link list controller sets link list information, and writes the link list information into the storage device to create a link list in the storage device. The link list has a plurality of nodes each having a next node address field. The link list information includes a data pattern configured to indicate an end of the link list as well as auxiliary information. The link list controller stores the data pattern into the next node address field of a link-tail node of the link list.

Abstract: In a flow-based network such as an open flow network system, even when a network appliance such as NAT and NAPT for translating a packet header is passed through, a correspondence relation of two flows before and after the passing can be grasped to make it possible to trace the flow in end-to-end. Specifically, a packet is encapsulated in a switch (or in a controller requested from the switch). By encapsulating by using the same header as a current header, two kinds of headers before the translation and after the translation are attached to the packet after the packet phases through the network appliance.

Abstract: The teachings herein describe methods and apparatuses for caching content at the “edge” of a wireless communication network, based on operating one or more RAN caches within the RAN portion of the network under the control of a gateway cache that operates at the packet data network interface level within the CN portion of the network. Each RAN cache operates as subordinate of the gateway cache, based on intercepting content requests from wireless devices operating within the RAN, providing corresponding proxied content requests to the gateway cache, and serving or not serving requested content from the RAN cache in dependence on control signaling from the gateway cache. Such operation permits all decision making to reside in the gateway cache, thereby retaining full visibility for critical billing and lawful intercept functions, while obviating in many instances the need to back haul such content.
