At present, streaming is a very popular technology by which multimedia content is delivered continuously from a server to end-users. New streaming approaches have been developed. Among of them, Dynamic Adaptive Streaming over HTTP (DASH) is aimed at providing video streaming services over HTTP (Hyper Text Transfer Protocol) in wired and wireless networks. DASH, which consists of a DASH server and client, operates mainly with the client. DASH server encodes and splits media content into segments with several bit rates. It represents encoded information as a metadata. Meantime, DASH client parses transmitted metadata from DASH server and then decides proper segments according to the current network condition. Even if DASH services are available in both wired and wireless environments, few client devices (non-DASH client in this paper) cannot support kinds of them. Therefore, we introduce and implement the design of a Network Adaptation Proxy(NAP) server for non-DASH clients by considering various network conditions with information of the data link layer in this paper. It provides stable DASH services and also guarantees the quality of the media contents to non-DASH clients.
