Abstract:
Moving the focus from nodes to information objects raises scalability
issues because the number of addressable information objects is huge
compared to the number of nodes, so scalable routing is an important
challenge issue of ICN. There are two types of naming scheme which
have been proposed in the ICN literatures: hierarchical and flat. To
guarantee clean separation of identifier from locator and scalability
of routing, we chose flat name and designed domain-based routing. A
significant requisite to be considered when flat name is used is an
efficient name-resolution system (NRS). Bloomfilter-based NRS [BF
NRS] is our proposal to this issue. Once a name is resolved into
locator(s), discovery and delivery steps are carried out based on the
routing scheme of locator. For scalability in routing of locator,
network is projected into hierarchically-organized domain structure.
A domain is a group of nodes or other domains. This composition could
be physical or logical. Each domain has its own identifier, and the
concatenation of domain IDs from top level domain to a certain domain
which a node belongs to plays the role of "locator" for that node.
Each domain has one or more domain gateways. All traffic from/to the
domain should pass through any of domain gateways. Routing
information based on this type of locators is exchanged among domain
gateways by using modified link-state routing protocol which can
suppress LSA explosion [LSR]. Thanks to this hierarchical domain
structure, locators are highly aggregatable (which means scalable
routing), and any node in heterogeneous network can communicate each
other.
