CCDN: CONTENT-CENTRIC DATA CENTER NETWORKS
ABSTRACT
Data centers have become the hubs for Internet services and applications. An enormous
amount of data is processed and shared among servers in a data center, which puts pressure on
the data center network to provide high end-to-end throughput.
EXISTING SYSTEM
Recently, researchers are exploring an alternative way to improve the data center network
performance, i.e., by intelligent caching and increasing the access points for hot data chunks. The
fundamental intuition comes from the fact that data chunks are usually repeatedly accessed in a
data center, and hot chunks might be concurrently read by even hundreds of nodes. These hot
spots easily result in oversubscribing links, and consequently increasing overall application
response times. Given that data center file system applies few file replicas with non-trivial file
size, such hot spot issue limits end-to-end network throughput.
DIS ADVANTAGES
 Increases the overall application response times.
 Limits end-to-end network throughput.
PROPOSED SYSTEM
To address the challenges, we design the Content-Centric Datacenter Network (CCDN),
which is a distributed system for caching, locating the content, and responding to subsequent
requests. The fundamental contribution of CCDN is to enable forwarding data request to the
nearest caching server as well as maintaining the cache consistency in a distributed and practical
way. To this end, CCDN depends on a hybrid of content-based and location-based forwarding
mechanism in switches to forward a content request to the correct target server on a hop-by-hop
basis. Specifically, CCDN enhances the traditional content-based forwarding to be direction-
aware to find the nearest target server and enhances traditional location (IP)-based forwarding to
make high utilization of the precious memory space in switches.
