摘要： A method for managing a multiple level cache of a host comprising a primary cache which is a volatile memory such as a DRAM memory and a secondary cache which is a non-volatile memory such as a SSD memory. The method comprises, if a segment identification data has been computed in said segment hash table, a corresponding processing core checks whether a corresponding packet is stored in a first portion of a primary cache or in a second portion of a secondary cache,
- if the packet is stored in said first portion, said corresponding packet is sent back to a requester and a request counter is incremented, a DRAM segment map pointer entering in a DRAM-LRU linked list, the DRAM segment map pointer being prioritized by being moved on top of said DRAM-LRU linked list,
- if the packet is stored in said second portion, said corresponding packet is passed to an SSD core so as to copy the entire given segment from the secondary cache to the primary cache ; then said request is passed back to said corresponding processing core in order to create the DRAM segment map pointer for pointing to the first portion storing said corresponding packet so as to be entered in said DRAM-LRU linked list, the SSD segment map pointer being also entered in said SSD-LRU linked list, the DRAM segment map pointer and the SSD segment map pointer being respectively prioritized by being respectively moved on top of said DRAM-LRU linked list and said SSD-LRU linked list; then said corresponding packet is sent back to said requester.

摘要： A device (D) is intended for organizing forwarding information into a node (N1) of a content centric networking comprising servers (CS1-CS3) storing permanent replicas of content items associated to name prefixes. This device (D) comprises a building means (BM) arranged for building into this node (N1) a forwarding information data structure, comprising for each name prefix a list of interfaces where a received packet of a content request can be forwarded towards servers (CS1-CS3), and a temporary forwarding information data structure (S2), comprising chosen detailed forwarding information associated to each full content item name of a currently requested content item associated to at least one of these name prefixes and to each full content item name of a recently requested content item associated to at least one of these name prefixes.
