Abstract: The present invention relates to an ICN router (1), comprising a first cache layer (L1) and a second cache layer (L2), the first cache layer (L1) comprising a first content memory (11) and the second cache layer (L2) comprising a second content memory (21), the second content memory (21) having a higher capacity but a slower access speed than the first content memory (11), the router (1) being configured so that the first cache layer (L1) is adapted to fetch data from second cache layer (L2) when the router (1) is requested to output said data, characterized in that the first content memory (11) presents a first block size and the second content memory (21) presents a second block size, the second block size being higher that the first block size, the first content memory (11) comprising a swap area (110) through which the first content memory (11) is connected to the second content memory (21), the swap area (110) being adapted for individually serving blocks at the first block size as parts of blocks at the second size fetched from the second content memory (21).
Abstract translation: 本发明涉及一种包括第一高速缓存层(L1)和第二高速缓存层(L2)的ICN路由器(1),第一高速缓存层(L1)包括第一内容存储器(11)和第二高速缓存层 L2)包括第二内容存储器(21),所述第二内容存储器(21)具有比所述第一内容存储器(11)更高的容量但更慢的访问速度,所述路由器(1)被配置为使得所述第一高速缓存层 当所述路由器(1)被请求输出所述数据时,L1)适于从第二高速缓存层(L2)获取数据,其特征在于,所述第一内容存储器(11)呈现第一块大小,并且所述第二内容存储器(21) 呈现第二块大小,第二块大小高于第一块大小,第一内容存储器(11)包括交换区域(110),第一内容存储器(11)通过其交换到第二内容存储器(21) ),所述交换区域(110)适于以第一块大小a单独地服务块 从第二内容存储器(21)提取的具有第二大小的块的部分块。
