INFORMATION CENTRIC NETWORKING (ICN) ROUTER

摘要

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).

1. 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).
