PopNetCod is a distributed caching policy, in which each router measures the local popularity of the content objects by analyzing the requests that it receives. It then uses this information to decide which Data packets to cache or evict from its content store. Since network coding is used, partial caching of content objects is supported, which facilitates the management of the content store. The routers decide the Data packets that they cache or evict in an online manner when they receive requests for Data packets. This allows the most popular Data packets to be cached closer to the network edges. The evaluation of PopNetCod shows an improved cache-hit rate compared to the widely used Leave Copy Everywhere placement policy and the Least Recently Used eviction policy. The improved cache-hit rate helps the clients to achieve higher goodput, while it also reduces the load on the source servers. date: 2019-04-25 date_type: published publisher: IEEE official_url: https://doi.org/10.23919/IFIPNetworking.2018.8696704 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1720931 doi: 10.23919/IFIPNetworking.2018.8696704 lyricists_name: Bourtsoulatze, Eirina lyricists_id: EBOUR79 actors_name: Bourtsoulatze, Eirina actors_id: EBOUR79 actors_role: owner full_text_status: public publication: 2018 IFIP NETWORKING CONFERENCE (IFIP NETWORKING) AND WORKSHOPS place_of_pub: Zurich, Switzerland, Switzerland pagerange: 271-279 pages: 9 event_title: 17th IFIP Networking Conference (IFIP Networking) 2018 event_location: Univ Zurich, Zurich, SWITZERLAND event_dates: 14 May 2018 - 16 May 2018 institution: 17th IFIP Networking Conference (IFIP Networking) book_title: Proceedings of the 2018 IFIP Networking Conference (IFIP Networking) and Workshops editors_name: Stiller, B citation: Saltarin, J; Braun, T; Bourtsoulatze, E; Thomos, N; (2019) PopNetCod: A Popularity-based Caching Policy for Network Coding enabled Named Data Networking.
