The Content Delivery Network (CDN) has become an important element in the Internet, which uses applicationlayer caches to improve user experience and reduce network/server load. However, CDNs face efficiency issues due to the following two reasons: 1) they are not aware of the network status, and 2) the underlying location-centric network (IP) does not understand content. At the same time, the Information-Centric...
Densely-deployed Content Delivery Network (CDN) solutions are used today for delivering a significant fraction of the Internet traffic through replication mechanisms. However, these networks show technological limitations when dealing with the proliferation of rich media-enabled applications such as video streaming. This paper introduces a new approach to content delivery incorporating Information-Centric...
Information Centric Networking (ICN) is a new kind of network architecture centered on content data. The ICN improves the efficiency of data transmission by the longest matching routing mechanism based on the content name prefix of the request interest packets, however, the multipath forwarding performance also resulted in the redundancy of the network content. The existing ICN forwarding strategy...
Content Delivery Network (CDN) is an effective solution to offer reliable and efficient content provisioning across the Internet. In order to ensure the service experience, it is critical to adopt efficient routing and server selection techniques in CDN. However, traditional CDN is unable to possess global knowledge of whole network and therefore lacks the ability to dynamically control routing and...
Large scale applications in data centers are composed of computers connected with a network. Traditional network switches do not perform routing based on packet contents. Thus, packets cannot be transmitted to the optimal computer for the request which is written in the packet payload. On the other hand, Deeply Programmable Network (DPN) switches can completely analyze packet payloads and perform...
The article describes an approach to create virtual cloud network laboratory. The topology is created with the visual editor. Then a script for network deployment is created. It is based on the scheme description. For implementation of this approach the cloud system based on OpenNebula has been created. The experiment has shown the efficiency of using cloud systems in IT education. Even the small...
The social media has changed our way of communication and sharing data in the Internet. They are based on the collaboration of the members to provide and exchange information. Their efficiency motivates researchers to design novel architectures based on the social behavior of the users. We study in this paper the combination of the social computing and the P2P systems. We propose ROUTIL: a P2P routing...
This paper considers multiple mobile robots for hospital logistics application. To increase the efficiency of using multiple robots, more than one delivery tasks can be assigned to a robot instead of delivering one package at a time. Since a robot can accept more than one task while delivering, a real-time routing method for visiting multiple pickup and delivery positions is required. This paper proposes...
This paper proposes a framework for systemic risk aware engineering of large-scale networks. Economics drives two major evolutionary trends in networked system design/operation: (a) towards the boundary of the system capacity/operational region, where all system resources are fully utilized, and (b) an increase in the system interconnectivity allowing enlargement of this region due to dynamic resource...
The Domain Name System (DNS) is used almost everywhere in mobile networks to determine the IP addresses of the network elements and thanks to the DNS architecture of the inter-operator IP backbone network, a network element of a public mobile network (PMN) can easily determine IP addresses of any other PMN. The analysis of some customers' complaints showed that it could be the cause of billing mistakes...
OpenFlow is currently the most commonly deployed Software Defined Network (SDN) technology. Some deployments designed with multi-controller OpenFlow have better scalability than standard OpenFlow. However, these deployments are not optimized for the Data Center Network (DCN), the cross-controller communication and routing may be inefficient. In this paper, we present the communication mechanism design...
today's cloud computing Data Centers (DCs) contain tens of thousands of servers with highly significant and remarkable bandwidth requirements as the demands of cloud computing applications, social applications, multimedia contents, and data intensive analysis are dramatically rising. Even thus, current DC technologies have following problems. First, power consumption of a Data Center Network (DCN)...
We present the lowest-path cost to destination scheme for identification of the most suitable node for data caching. The scheme identifies the network node that yields the lowest-cost path for delivering data to demanding users. This scheme is applied to information centric networks (ICN) that consider two different data consumption modes: frequently and sporadically. We consider the use of Software-Defined...
Many-to-Many (m2m) communication paradigm is an inevitable part of modern information exchange in telecommunication networks allowing synchronous data exchange among group of hosts. There are numerous underlying technologies and algorithms using m2m communication, in this paper we focus on dynamic provisioning of multicast-based routing for Elastic Optical Networks (EONs). We propose multilayer approach...
TOR (The Onion Router) TOR (The Onion Router) has been a very popular anonymous proxy service. Since its first usage, TOR has been improved and become a very big network consisting more than 7000 relays. Beside used by journalist, activist, and writer as a tool for their freedom of speech, its highly anonymous service is also used by bot-nets, malware, distributed denial of service attacks, hidden...
Information-centric networking (ICN) promises to improve content-oriented services by enabling in-network caching and supporting optimal content request forwarding. To achieve this goal, different content caching and request forwarding schemes are proposed in multiple ICN architectures. However, they differ from each other in whether pervasive caching is adopted, and whether nearest-replica routing...
Named Data Networking(NDN) is a new networking architecture that centers around content distribution. However, service provision is equally important for the deployment of this new architecture. Today, Internet services are typically provisioned by a number of discrete servers or server farms to improve service scalability, reliability and performance. Although TCP/IP network provides a rich set of...
This paper mainly introduces the basic functions of DNS, and its usage for mapping service in the Identifier Locator Split (ILS) schemes, as one transitionally functional component in future network architecture. As well known, the overloaded semantics of IP address, being used for both endpoint identifier and routing locator in traditional internet, has hindered the smooth support for mobility of...
The vision behind the Internet of Things (IoT) is that any things that need communications, are universally connected, and becoming an integral part of the future Internet. However, the existing of Low Power Networks (LPN) consisting of battery-powered nodes poses great challenge for traditional addressing and routing protocols. The paper proposes a geographical topology-enabled IPv6 addressing framework...
In Opportunistic Networks (Oppnets), a permanent fixed path is never assumed to be available between the source and destination. Nodes are not aware of changing network topology. So, static routing is not possible here and dynamic routing is best suited for such networks. In this paper, a Cloud Computing Based Routing Protocol (CCBRP) has been proposed for infrastructure-based Oppnets. It uses the...
