A Popularity-Based Collaborative Caching Algorithm for Content-Centric Networking
—The key aspect of Content-Centric Networking (CCN) is that the contents are cached by in-network nodes, and hence the caching scheme is important for the efficient use of cache and content delivery. Although the caching scheme in CCN has been widely researched, it is still a great challenge to better utilize in-network caching of CCN with an appropriate caching scheme. In this paper, we propo...
متن کاملTowards Popularity-Based Caching in Content Centric Networks
Today’s Internet was created aiming to share resources. The chosen model was therefore a conversation mechanism between two machines: the messages are exchanged between two host according to source and destination addresses of IP datagrams. This led to a model with strong coupling between where and what, even when most of the users value the Internet for what content it contains. As well locati...
متن کاملEnhancing the B+-tree by dynamic node popularity caching
We propose the Cache Coherent B-tree (CCB-tree), an indexing structure that can improve search performance compared to the traditional B-tree. The CCB-tree makes use of the unused space in the internal nodes of a B-tree to cache frequently queried leaf node addresses, thus saving node accesses. An experimental study shows that the CCB-tree can outperform the traditional B-tree on workloads wher...
متن کاملContent registration in VANETs - saving bandwidth through node cooperation
Search indices for distributed information are an important building block for many mobile, decentralized applications. However, the network load caused by nodes registering their information in the index can become quite significant especially in mobile networks like vehicular ad-hoc networks (VANETs), where nodes need to register periodically due to their mobility. Our goal in this paper is t...
متن کاملContent-Based Block Caching
In this paper we propose a novel cache management mechanism termed the Content-Based Buffer Cache. The Content-Based Buffer Cache (CBBC) attempts to maintain a single copy of any block in memory according to its contents. In the presence of repeated content, this mechanism increases the effective size of the buffer cache. Overheads for maintaining this extra state information are small and boun...
