If we change a global value in L1 cache, does it change in L2 and global memory or do we only do a mark as dirty value and flush the writes later? Is the cache policy a multilevel inclusion one (L1 is ALWAYS present in L2), or is it exclusion as in L1 and L2 unified cache (L1 is NEVER in L2)

A cache’s write policy is the behavior of a cache while performing a write operation. A cache’s write policy plays a central part in all the variety of different characteristics exposed by the cache. Let’s now take a look at three policies: 1. write-through 2. write-around 3. write-back See more In this tutorial, we’ll learn about the different ways to implement write operations in a cache.

Information-centric networking (ICN) is an approach to evolve the Internet infrastructure away from a host-centric paradigm, based on perpetual connectivity and the end-to-end principle, to a network architecture in which the focal point is identified information (or content or data). Due to the inherent caching capability of the nodes in an ICN, it can be viewed as a loosely connected network of caches, which has unique requirements of caching policies. However, ubiquitous con…
