Title
(EN) Method for operating a cache arranged along a transmission path between client terminals and at least one server, and corresponding cache
(ZH) 用于操作沿客户端终端和至少一个服务器之间的传输路径布置的缓存器的方法、及相应的缓存器
front page image
Abstract
(EN) Cache (DANE) located along a transmission path between client terminals (CT) and at least one server (SE) and configured to receive requests from client terminals (CT) for segments of a multimedia content available at several representations, which comprises: an interface of connection (1) for receiving, from a first client terminal, a first request for a preferred representation and at least one alternative representation of a given segment of said multimedia content; a matching module (5) configured to determine if at least one ongoing representation of said given segment, already requested by the cache from a server for a further client terminal, matches the preferred representation or an alternative representation of the first request.
(ZH) 一种包括缓存器(DANE)的网络设备，该缓存器(DANE)位于沿客户端终端(CT)和至少一个服务器(SE)之间的传输路径，并且被配置为从客户端终端(CT)接收针对以若干表示可用的多媒体内容的片段的请求，该缓存器包括：‑连接接口(1)，其用于从第一客户端终端接收针对所述多媒体内容的给定片段的优选表示和至少一个替代表示的第一请求；‑匹配模块(5)，其被配置为确定已被缓存器从服务器请求用于进一步的客户端终端的所述给定片段的至少一个正在进行的表示是否与第一请求的优选表示或替代表示相匹配。
