“…Users can now organize tenants according to a group hierarchy and allocate capabilities accordingly. HNS manages names and their relations in their natural form, supporting any complex graphs [27]. Moreover, namespaces in Kubernetes allow resource management, which is helpful in a multi-tenant environment.…”

The micro cloud model offers cloud behavior at the edge of the network. It allows dynamic organization of the resources, closer to the users and the data. One of the crucial problems to solve is to design a proper cloud model at the edge of the network and offer cloud services that support multi-tenancy. This cloud property is a governing mechanism to lower cloud costs. It is essential for the scalability of both public and private clouds due to the utilization of shared resources and the logical separation of tenants. This paper presents the model for the creation of virtual clouds (vClouds) on physical infrastructure using a hierarchy of namespaces, with proper organization and redistribution of resources such as CPU, RAM, and storage, while preserving logical isolation between vClouds, thus creating a multi-tenant system. The presented model guarantees accurate resource redistribution through graph transformations to model operations, while the proposed protocols ensure correctness by employing multiparty session types for modeling. We extend the secure computing mode to establish an isolated system, allowing sandboxing rules for every namespace and creating hierarchies of security profiles. This advancement enables our model to inherit parent security profiles fully, extend them by adding child-specific elements, or redefine and create entirely new ones. Furthermore, the users can switch context, meaning they can change vCloud or the namespace they operate on.INDEX TERMS Cloud computing, distributed systems, edge computing, formal specifications, infrastructure as software, platform, namespaces, isolation, multi-tenancy.• We enable users to switch between contexts, meaning they can change vCloud or the namespace they operate on.These advancements rely on our following technical contributions:• Protocol definitions for namespace manipulation:This study defines protocols for performing crucial operations, such as creating, updating, and deleting namespaces within virtual clouds, leveraging the power of rules for graph transformations over namespaces.

“…This extension helped reduce system latency and increase its throughput. Mohammad et al [5] proposed a disaster NDN information dissemination with complex graph-based namespaces, automatic name-based load-splitting support on a recipient-based publish/subscribe architecture. Their system improved state-of-the-art NDN in terms of information delivery time and load sharing.…”

After a disaster happens, effective communication and information sharing between emergency response team members play a crucial role in a successful disaster response phase. With dedicated roles and missions are assigned to responders, role-based communication is a pivotal feature that an emergency communication network needs to support. Previous works have shown that Named Data Networking (NDN) has many advantages over traditional IP-based networks in providing this feature. However, these studies are only simulation-based. To apply NDN in disaster scenarios, real implementation of a deployment architecture over existing infrastructure during the disaster should be considered. Not only should it ensure efficient emergency communication, but the architecture should deal with other disaster-related challenges such as responder mobility, intermittent network, and replacement possibility due to disaster damage. In this paper, we designed and implemented an NDN-based disaster response support system over Edge Computing infrastructure with KubeEdge as the chosen edge platform to solve the above issues. Our proof-of-concept system performance shows that the architecture achieved efficient role-based communication support, fast mobility handover duration, quick network convergence time in case of node replacement, and loss-free information exchange between responders and the management center on the cloud.

“…In-network content caching in routers is an important feature of ICN, allowing for requests to be satisfied from an intermediate cache on the path to the server/repository [9]. An in-network namespace is generally a graphical structure that captures the content names and their relationships in an ICN's content space [12]. Despite both being ICNs, NDN and MF have important differences [16,20]: NDN uses human-readable hierarchically-structured names, with Longest Prefix Matching-based forwarding.…”

The Internet is composed of many interconnected, interoperating networks. With the recent advances in Future Internet design, multiple new network architectures, especially Information-Centric Networks (ICN) have emerged. Given the ubiquity of networks based on the Internet Protocol (IP), it is likely that we will have a number of different interconnecting network domains with different architectures, including ICNs. Their interoperability is important, but at the same time difficult to prove. A formal tool can be helpful for such analysis. ICNs have a number of unique characteristics, warranting formal analysis, establishing properties that go beyond, and are different from, what have been used in the state-of-the-art because ICN operates at the level of content names rather than node addresses. We need to focus on node-to-content reachability, rather than node-to-node reachability. In this paper, we present a formal approach to model and analyze information-centric interoperability (ICI). We use Alloy Analyzer's model finding approach to verify properties expressed as invariants for information-centric services (both pull and push-based models) including content reachability and returnability. We extend our use of Alloy to model counting, to quantitatively analyze failure and mobility properties. We present a formally-verified ICI framework that allows for seamless interoperation among a multitude of network architectures. We also report on the impact of domain types, routing policies, and binding techniques on the probability of content reachability and returnability, under failures and mobility.
