Parallel Router Design for Content Centric Networks
نویسندگان
چکیده
Today’s routing infrastructure is built using special purpose hardware due to the demand for very high throughput. With the growth of hardware techniques, satisfying this huge demand is made possible. However the downside of this hardware based architecture is that upgradation is very rare due to high costs and extensibility is limited which heavily limits the deployment of additional features or new routing policies. Recently, Software routers have gained more traction due to it extensible nature. Though their performance is still behind hardware routers, solutions like RouteBricks are trying to close this gap. In order to scale to higher speeds, a parallelized architecture has been proposed where a cluster of commodity machines are used to achieve higher throughput. In this paper, we analyze the generic issues in porting routing policies on to this type of parallel architecture. We illustrate this by parallelizing Content Centric Routing using different designs and explain the key issues with every design and also help in choosing the optimal design based onthe underlying architecture.

Information-centric network (ICN) is a novel architecture identifying data as a first class citizen, and caching as a prominent low-level feature. Yet, efficiently using large storage (e.g., 1 TB) at line rate (e.g., 10 Gbps) is not trivial: in our previous work, we proposed an ICN router design equipped with hierarchical caches, that exploits peculiarities of the ICN traffic arrival process. I...

Content-centric networking (CCN) is one of the major proposals for realizing information-centric networking. CCN routers cache forwarded data in a buffer memory called the ContentStore (CS). Virtual content-centric networking (VCCN), which enables the construction of multiple virtual networks (called VCCN slices) on a content-centric network, has been recently proposed. When multiple VCCN slice...
