One of the biggest technical issues in the upcoming Metaverse-based society is the support of interoperability between different Metaverse platforms. This interoperability will enable users to experience a continuum of platform-independent services and activate a new Metaverse-based ecosystem. In this paper, we propose AIM, an architecture supporting interoperability between different Metaverse pl...Show More
5G MEC is likely to be a hybrid standard that consists of standards of multiple SDOs, mainly ETSI and 3GPP. To avoid expected deployment and operation cost increase and difficulty in interoperability, careful considerations on a unified framework and functional blocks is highly required. This paper reviews 5G MEC related standardizations of ETSI and 3GPP from the perspective of the unified framewo...Show More
Recent studies in the field of Information-Centric Networking (ICN) suggest the need for push-based communication, which is not supported by current pull-based ICN architectures such as Name Data Networking (NDN). There are limitations in using pull-based communication for real-time event transmission in IoT environment. We propose a subscription-based push mechanism that can be applied in a speci...Show More
Information Centric Networking (ICN) has been proposed to address recent data explosion issue more efficiently than the legacy TCP/IP and Named Data Networking (NDN) is a representative mechanism to realize the ICN concept. For the successful migration to NDN, it needs to support current and expected popular applications in efficient manner. The Publish/Subscribe is a typical example of these appl...Show More
Current approaches for Publish subscribe over Named Data Network(NDN) have limitations for supporting full Publish Subscribe operations over NDN. In this paper, we propose a design of publish subscribe system over NDN, which encoding the ApplicationParameters of NDN Interest Packet for Publish/subscribe operations over NDN. Our approach not only fully supports publish subscribe operations over NDN...Show More
Compared to legacy TCP/IP networking, a notable feature of ICN is to utilize in-network storages. ICN architectures basically adopt on-path caching mechanism. However, the benefits of on-path caching are limited because the caching is bounded to ICN nodes on the request path. To overcome the limitation of on-path caching mechanism, various types of off-path caching mechanism have been proposed. Th...Show More
The provision of Internet connectivity for a vehicle anywhere anytime is an essential element to realize the vision of Connected Car. However, we observe that the current vehicular network technologies mainly focus on single-hop communications having limited coverage for the Internet connectivity. Accordingly, in order to support the always Internet connectivity, multi-hop routing that can cover w...Show More
Generally, there is a Distributed Denial-of-Service (DDoS) detection and defense mechanism in router near the victim host and packet filtering routines are initiated during the attack continues. By the way, it would be better an attack packet blocking mechanism is in router closed to the attacker for downsizing attack traffics in network. This paper presents attack route diagnosis, a technique tha...Show More
The main usage pattern of internet is shifting from traditional host-to-host central model to content dissemination model. It leads to the pretty prompt growth in Internet content. CDN and P2P are two mainstream techmologies to provide streaming content services in the current Internet. In recent years, some researchers have begun to focus on CDN-P2P-hybrid architecture and ISP-friendly P2P conten...Show More
Link-state routing protocols have the advantage of robustness, support of the shortest path routing, and a fast convergence time in comparison to distant vector routing protocols. However, owing to scalability problems, link-state protocols are traditionally used only for intra-domain routing on the Internet. In this paper, we present hierarchical link-state routing (HLSR), a hierarchical link-sta...Show More
To overcome limitations of existing silo type IoT, a internetworking framework is essential. IPv6 based internetworking framework is state of the art technology. However, since the IPv6 based framework still follows the original IP networking concepts, it inevitably inherit its limitations. This paper proposes a new internetworking framework optimized to the IoT environment under the name of MOFI-...Show More
With the pretty prompt growth in Internet content, the main usage pattern of internet is shifting from traditional host-to-host model to content dissemination model. To support content distribution, content delivery networks (CDNs) gives an ad-hoc solution and some of future internet projects suggest a clean-slate design. Web applications have become one of the fundamental internet services. How t...Show More
Multicasting is a way to deliver copies of single message to multiple recipients at different locations. On the traditional internet, group members join specific multicast address through membership management protocol and packets are delivered along the path tree built by multicast routing protocol. Now we consider how multicast-style communication can be designed in id/locator separation environ...Show More
In current internet, there are always scalability problems because it has a flat network model. It is possible to solve a scalable routing problem as use a hierarchical network model instead of a flat network model. By the way, there is no solution for routing protocol available in hierarchical network model. The routing protocol for that must provide many functions different from current routing ...Show More
In current Internet, network API acts as a bridge between application and network and the importance of its role is growing. However, it has inherent limitation of tight-coupling which makes almost indivisible all the network environments, such as transport controls and network-specific addresses. This coupling not only makes it difficult to change one without changing another, but also prevents b...Show More
Multicasting is a way to deliver copies of single message to multiple recipients at different locations. On the traditional internet, group members join specific multicast address through membership management protocol and packets are delivered along the path tree built by multicast routing protocol. Now we consider how multicast communication can be designed in ID/locator separation environment. ...Show More
The paradigm shift from the current host-centric networking to information-centric networking (ICN) generates much interest in the research community. In ICN, the primary communication entity is contents and uniquely identifiable names are assigned directly to the contents, where the names are independent of their locations. Thus, content naming and routing are the key challenges in ICN. In this p...Show More
Moving the focus from nodes to information objects raises scalability issues, therefore name-based routing and name resolution should be designed to scale accordingly. There are two types of naming scheme: hierarchical and flat namespace. To guarantee clean separation of identifier (name) from locator and scalability in routing, we chose flat name and designed domain-based routing. A significant r...Show More
In traditional multi-path routing schemes such as ECMP(Equal-Cost MultiPath), a method to generate multi-path computes only the lowest equal cost paths based on Dijkstra algorithm. This method is appropriate to link cost sensitive network such as flat network model. However, it is not proper to hierarchical network model that is less sensitive to link cost and interested in cost-length tradeoff. A...Show More
This paper presents evolving Future Internet Architecture to exploit in-network functions as realizing basic Identifier and locator separation scheme, which is a notable design principle for most of Future Internet Architecture. First of all, software-centric in-network functions, such as identifier and locator separation, network model, and etc. motivated from MOFI, can be implemented and managed...Show More
It has been shown that the Internet environment has rapidly changed from fixed to mobile one with the wide popularity of smart phones and the emergence of various wireless/mobile networks. Thus, in research community there has been a consensus that separating Identity (ID) from Locator (LOC) is a one promising concept to address intrinsically such a change. In this paper, we propose a mathematical...Show More
The newly emerging 5G mobile communication system requires an effective design of core network to cope with the mobile data traffic explosions. In this paper, we propose a new architecture for 5G mobile core network, RB-Core, to efficiently deal with such the data traffic explosion problem. The proposed RB-Core network is designed by adopting a distributed architecture and by using the Routing Bri...Show More
The future Internet will be evolved to mobile-oriented environments, and thus the mobility support is a key issue in the design of future Internet. This paper proposes a distributed identifier-locator mapping system (DMS) for the future mobile-oriented Internet environment, which is designed on the identifier-locator (ID-LOC) separation principle. The proposed DMS scheme is implemented over Linux ...Show More
We propose an identifier to locator (ID/LOC) mapping scheme to resolve a locator for a flat identifier and a location update scheme to support dynamic mobility across the global Internet. The aggregation of flat identifiers is not feasible, which can lead to an explosion of binding information between ID and mapping server storing ID/LOC mapping. Also an efficient management of heavy location upda...Show More
