With the growing popularity of big-data applications, Data Center Networks increasingly carry larger and longer traffic flows. As a result of this increased flow granularity, static routing cannot efficiently load-balance traffic, resulting in an increased network contention and a reduced throughput. Unfortunately, while adaptive routing can solve this load-balancing problem, network designers refrain...
Conventional datacenters, based on wired networks, entail high wiring costs, suffer from performance bottlenecks, and have low resilience to network failures. In this paper, we investigate a radically new methodology for building wire-free datacenters based on emerging 60GHz RF technology. We propose a novel rack design and a resulting network topology inspired by Cayley graphs that provide a dense...
Wi-Fi Mesh Community has turn out to be an important area community to offer internet to challenge the thrown domains and wireless link in metropolitan environments. In this paper, hassle of figuring out the most to be had bandwidth direction is targeted, which is an essential problem in helping pleasant-of-carrier in WMCs. Due to the concept of interference, bandwidth, which is a familiar challenging...
Geographic routing protocols require only local information for routing decisions and thus is considered very efficient in large-scale wireless networks such as Vehicular Ad-hoc Networks (VANETs). In geographic routing, one of the neighbor of sender vehicle is selected as next forwarding vehicle to forward the message to the destination nodes. Various geographic routing protocols have been proposed...
Mobile Ad Hoc Networks (MANETs) merge wireless communication with higher node mobility. Restricted wireless communication range, and node mobility requires cooperation with all others to offer networking, and with the network changing vigorously, needs are to be continually met. Routing protocols allows MANET operation. To improve the performance of the routing, various constraints such as bandwidth...
Software Defined Networking (SDN) has emerged to be an ultimate solution for the management of data centers. The separation of control plane from the data plane has made it possible to manage physical and virtual networks through the SDN controller. This paper presents a novel Dynamic Multipath Scheduling Protocol (DMSP) for effective scheduling of packets on SDN virtual links, thus achieving full...
In datacenter networks, big scale, high performance and fault-tolerance, low-cost, and graceful expandability are pursued features. Recently, random regular networks, as the Jellyfish, have been proposed for satisfying these stringent requirements. However, their completely unstructured design entails several drawbacks. As a related alternative, in this paper we propose Random Folded Clos (RFC) networks...
Software Defined Network (SDN) is an emerging networking paradigm which separates the control plane from the data forwarding plane. The centralized controller provides the global view of the distributed network states for user applications. However, the scalability of SDN is subject to the delay, the capacity of the controller, the bandwidth of the control channel, and other issues. To solve this...
The distributed, hop-by-hop routing architecture used in the Internet depends on algebraic properties of routing metrics to ensure traffic is forwarded over loop-free and best (LFB) paths. As the Internet evolves to serve as the converged communication infrastructure for the 21st century, the need for new metrics that violate these properties ([5], [9]) has been identified. Until recently, the behavior...
A decentralized coded caching technique is introduced for wireless ad hoc networks in which all the existing contents are randomly combined and cached. The scaling behavior of the network is studied in terms of both capacity and security. Proactive and reactive routing techniques for coded caching are presented and the scaling capacity of the network for each case is derived. It has been shown that...
Extreme-scale science applications are highly innovative and constantly evolving. They are expected to generate data in the petabyte and exabyte ranges. This data needs to be transferred, processed, and analyzed at remote locations. A flexible data retrieval service is needed, where a user requesting data retrieval from a remote site can have a choice between replicated storage sites. Elastic Optical...
A Bandwidth reservation is an essential component in providing of quality of service (QoS) in vehicular ad hoc networking (VANENTs). The recommended MAC protocol for VANET experiences a high percentage of packet loss. Somehow its performance can be improved by using Time Division Multiple Access (TDMA) techniques. In this paper, we propose a new algorithm for multi-constrained QoS routing and show...
The purpose of this research is to address the issue of enhancing the Quality of Service(QoS) in IP networks, to make it more optimal in a given network of networks using a novel approach. In this approach, QoS is provided to the packet even when the packet crosses its access network into the backbone. It proposes a new design or set of features in the routers which maps and translates the QoS provisioning...
Since network configurations in the Internet are getting complicated, managing networks has become a heavy task. As an attempt to solve this problem, the concept of Intent-Based Networking (IBN) has been proposed. While intent of a network administrator in conventional networks is used to be expressed in concrete description of configurations stored on devices each, intent of an administrator in IBN...
Software-Defined Networking (SDN) provides an abstraction of the network that allows network administrators to configure network devices seamlessly across the enterprise networks. Although SDN has created a new paradigm in next generation network, centralized controller architecture in SDN imposes overhead issue because control plane will handle all flows regardless of size and priority. Besides that,...
In providing new telecommunication services, the requisition for quality of network is more and more popular and sophisticated with high bandwidth, small value of delay time or packet loss etc. To assure the quality of network, the localized routing schemes have recently been researched as a promising alternative to the currently deployed global QoS routing schemes. Different from the traditional...
