License open source refers to all licensing conditions that meet the definition published from time to time by the Open Source Initiative, as stated in the following link: and which contain, without restriction, (a) GNU`s General Public License (GPL) or Lesser/Library GPL (LGPL); (b) artistic license (p.B. PERL); (c) Mozilla`s public license; (d) creative Commons Attribution-ShareAlike (“CCL”); (e) Open Database License (ODbL); and (f) the Apache or other license. The component also contains adapters to convert between PSR-6, PSR-16 and Doctrine caches. See the interoperability adapter between the CACHE PSR-6 and PSR-16 adapters and the Doctrine cache adapter. The Time aware Least Recently Used (TLRU)[10] is a variant of LRU developed for the situation in which the content stored in the cache has a valid lifespan. The algorithm is suitable for network applications such as IcN (Information Network), Content Delivery Networks (CDNs) and distributed networks in general. TLRU introduces a new term: TTU (time to use). TTU is a time stamp of a content or page that determines how long the content will be used based on the location of the content and the content publisher`s ad. Thanks to this local time stamp, TTU gives the local administrator more control in the regulation of network memory. When content enters the TLRU algorithm, a cache node calculates the local TTU value based on the TTU value assigned by the content publisher. The local TTU value is calculated using a locally defined function.

Once the local TTU value is calculated, the content exchange is performed for a subset of the content stored in the cache node. The TLRU ensures that less popular and cheaper content is replaced by incoming content. A cache can store data that is calculated if necessary and not recovered from a backup memory. Memorization is an optimization technique that records the results of functional call resource users in a search table, so that subsequent calls can reuse stored results and avoid repeated calculations. It refers to the dynamic methodology of programming-design algorithm, which can also be considered a means of storage. The “Least Frequent Recently Used” (LFRU) cache replacement scheme[11] combines the benefits of LFU and LRU schemes. LFRU is suitable for “network” cache applications, such.B as IcN (information network), content distribution networks (CDNs) and distributed networks in general. In LFRU, the cache is divided into two partitions called preferred and non-preferred partitions. The preferred partition can be defined as a protected partition. If the content is very popular, it is moved to the preferred partition. Replacing the preferred score is as follows: LFRU removes the content from the unprivileged score, moves the content from a preferred score to an unprivileged score, and inserts new content into the preferred score. In the above procedure, the LRU is used for preferred partition and an LFU (ALFU) diagram approached for the non-preferred partition, hence the abbreviation LFRU.
