We propose a method of constructing a layer 3 (L3) network that consists of a large number of virtual machines (VMs) for a large-scale IoT emulation testbeds by utilizing Hierarchical/Automatic Number Allocation Protocol (HANA). The L3 network consists of several subnets, and suppresses the number of MAC addresses that must be distinguished from each other. HANA releases a burden of an L2 switch,...
The infrastructure that supports the digital world is adopting network and system virtualization to raise its reliability and flexibility. However, the allocation of such virtual resources is still performed by human administrators, which limits the agility of such systems to respond to events and new requirements. In this paper we propose an architecture that exploits the capabilities offered by...
The Internet is facing the accelerating growth of routing table size. Backbone routers' routing table has already reached 512k entries, which has a negative effect on the scalability of the Internet. Hierarchical addressing and locator/ID separation solutions have been proposed to address the scalability issue. However, there has been little focus on how to efficiently represent hierarchical location...
Network virtualization techniques enable network service providers to implement and provide multiple logical networks on a common physical network infrastructure. It is essential to guarantee quality of services (QoS) by automatically selecting appropriate network and computer resources to virtual networks (consisting of edge, core networks and data-centers) requiring high level of QoS when the surrounding...
This paper proposes route advertisement policies (RAP) for the Border Gateway Protocol (BGP) with provider aggregatable (PA) addressing. The proposed RAP takes the advantage of address aggregation opportunity. If multiple address spaces are allocated to each of autonomous systems (ASes) that are multihomed to multiple upper ASes, reduction of the Forwarding Information Base (FIB) and quick convergence...
As the Internet of Things technologies evolve, billions of smart devices will be connected to the Internet. Therefore, the accelerated growth of users, applications and devices pose a great demand on the scalability of the Internet. In this paper, we develop a new Internet architecture -- Multiple-inherited Locators (MiL) -- to meet the future demand on addressing. MiL is based on Locator/ID addressing...
Hierarchical address allocation and hierarchical routing design has long been suggested to reduce the forwarding information base (FIB) size in the Internet core. However, the hierarchical design is not put into practice. We implemented the hierarchical and automatic number allocation (HANA) protocol for allocation of IPv4 and IPv6 address spaces to autonomous systems (ASes) and the FIB size reduction...
We propose and implement an enhanced moving average (MA) based dynamic resource allocation method for optical packet and circuit integrated (OPCI) networks. In the OPCI networks, optical packet switching (OPS) and optical circuit switching (OCS) share the total bandwidth in a fiber by allocating separate wavelength resources to them. In this work, we leverage an exponential moving average (EMA) as...
Due to the continuously expanding scale of the Internet and increasing demand for highly available networks, there is strong desire for provider-aggregatable (PA) addressing and the accompanying multi-address-based multihoming scheme, which can efficiently reduce the size of the global routing table in core routers and boost the availability of networks. The growing demands on PA addressing (e.g.,...
A Hierarchical Automatic Number Allocation (HANA) protocol, which allocates locators to ASes hierarchically, is one solution for the problem of BGP table increase. We describe hierarchical inter-AS locator allocation by HANA and emulate locator allocation on a huge-scale network consisting of 10,000 ASes, which are extracted from the actual Internet topology. We prove that locator allocation was accomplished...
