Current approaches to Information-Centric Networking (ICN) facilitate the publication and retrieval of content in a network through a variety of discovery, caching and forwarding approaches, thus defining an equivalent of the data plane in the current Internet infrastructure. However, in contrast to the current Internet, ICN lacks a definition of the control plane for the management of the operation...
Everything can be mobile, from end-hosts to applications. The need for mobility management is rising rapidly due to the increasing number of mobile devices and the advent of new types of mobile object, such as Internet of Things devices, connected vehicles, wearable devices, and virtual machines. In order to support various types of mobility, we propose an integrated and distributed mobility management...
A low-latency and reliable message switching network is critical for constructing high-speed datacenter networks. In this paper, we present the design, implementation, and evaluation of a novel Location basEd Source Switching (LESS) for datacenter networks. LESS enables lightweight source switching through a location-based addressing scheme. Each switch and host can independently derive a source route...
With constant evolution of the Internet, many of its even well-established properties continue to change. This study re-evaluates the stability and diversity of Internet paths and whether it is affected by the widely deployed Multi-Protocol Label Switching (MPLS). In particular, using traceroutes between large number of source-destination pairs with the Internet Control Message Protocol (ICMP) extensions...
This paper addresses mainly the problem of private data protection in network communication against eavesdropping attacks. As this kind of attacks is stealthy and untraceable, it is barely detectable for those feature detection or static configuration based passive defense approaches. We propose a Moving Target Defense(MTD) method by utilizing the protocol customization ability of Protocol-Oblivious...
A network topology algorithm based on SNMP was put forward and implemented. This algorithm could confirm the connection between ports and improve the efficiency of discovery through combining the topology discovery of the network layer and the link layer. It could solve the problem of subnet information redundancy and incomplete information of address forwarding table during the discovery. The experimental...
This paper proposes an emulated model of an academic networking testbed by using SDN. This emulated model consists of switching and routing topologies and has been tested to be successfully working for layer (data link) two and layer three functionality. The increasing prices of the every new generation of networking hardware puts budgetary challenges to academic units. The need of the addition of...
Through the introduction of mobile IP functional entities, the paper elaborated on the operation mechanism of mobile IPV4. According to mobile IP mechanism, the paper analyze the reasons for the formation of mobile IPV4 triangular routing, and describe a method to solve the triangular routing, On the basis of IPV6 concept, the paper analysis the mobile IPV6, then discuss the IPV6 movement of the working...
Recent SDN researches suffer from over-accumulation of unhealthy flow-load. Instead, we leverage the SDN controller network view to encode the end-to-end path information into the packet address. Our solution EncPath significantly reduces the flow-table size and the number of control messages. Consequently, the power consumption of network switches is in orders of magnitude less than other evaluated...
Multi-Processors Systems-on-Chip (MPSoCs), as a key technology enabler of the new computation paradigm Internet-of-Things (IoT), are exposed to attacks. Malicious applications can be downloaded at runtime to the MPSoC, infect IPs and open doors to perform timing attacks. By monitoring the Network-on-Chip (NoC) traffic, an attacker is able to spy sensitive information such as secret keys. Previous...
This paper proposes an energy-aware packet delivery operation through network node clustering for green communications. Energy consumption has become a key factor for the evaluation of performance index in telecommunication industry. In order to prevent a waste of energy in wired network, the proposed algorithm configures energy-aware cluster consisting of one header node and multiple member nodes...
Information-Centric Networks (ICN) is a communication paradigm that promises to transfer the Internet from a host-to-host communication network to a massive information delivery system, capable of supporting the future needs of the users. ICNs are based on three main concepts: content forwarding, in-network caching, and multicasting. To realize these three key concepts, Software-Defined Networking...
Traditional Internet based on the IP routing has an innate deficiency when facing up with large numbers of concurrent distribution of video and other media content. Software-Defined Networking (SDN) and OpenFlow protocol try to improve data transfer efficiency and flexibility by separating the forwarding layer and control layer, and the content-based routing idea proposed by Content-Centric Networking...
A number of today's over-the-top (OTT) services could greatly benefit from a scalable and efficient network-layer multicast support on the Internet. IP multicast showed to not meet these requirements and, thus, is not available for this purpose. Content Delivery Networks emerged as global alternative but usually end at the border of ISP networks. Software-Defined Multicast (SDM) is proposed in a previous...
Nowadays the use of enterprise VPN services is integrated in every larger company. SOHO and SMB also use VPN for connection with internet providers, VoIP, banking transactions. Our approach suggests to automatize building and using multicomponent VPN topologies. We also proposed the cloud to build full-mesh dynamic multipoint VPNs based on routers using scripts.
Virtual Machines (VMs) and network virtualization technologies have been widely used for cloud computing. Active VMs can move to other execution environments, an action called "live migration." VMs must have the same IP address before and after migration. Therefore, live migration must be in the same segment. For this reason, network virtualization technologies are used to make a wide area...
We present a system to enable the multipath routing for unicast traffic in Ethernet network that implements Depth First Search algorithm to find all possible path between source and destination Data-Path Identifier (DPID) pairs. The system uses DPID as the locator identifier and Media Access Control (MAC) address as the host identifier, Proxy Address Resolution Protocol (ARP) to handle ARP Request...
The communications infrastructure of the electric grid has been evolving rapidly in the last decades due to the need for transporting ever more sophisticated information, both data and control. More recently Ethernet based networks have been added into the picture, as modern relays need to communicate with control and dispatch centers and centralized management systems over local and wide area networks...
Information-centric networking (ICN) and software defined networking (SDN) are two novel network paradigms that the networking community is actively investigating. Because of their salient features, there are increasing attempts to integrate ICN and SDN. In this paper, we show how a recently proposed future Internet architecture (called CoLoR) makes it efficient to integrate SDN and ICN. In particular,...
Data centers are over provisioned to handle traffic surges. However, various studies of data center traffic regarded this upsurge as a rare event and shown that the resources of data center are underutilized. Hence, there is a need to conserve energy by providing control knobs that turn the resources of data center on/off according to the traffic condition. In this paper, we study the ability of 4-4,...
