Background/Objective: Interior gateway protocols are used for communication between devices in an organizational network. The setup which includes routers, switches and hosts is simulated in GNS3 software to represent a complex real time enterprise level network. Each protocol is implemented in the designed topology. Methods/Statistical analysis: Interior gateway protocols-RIP (Routing Information...
Named Data Networking (NDN) is a new Internet architecture that replaces today's focus on where — addresses and hosts — with what — the content that users and applications care about. A unique advantage of NDN over IP is the adaptive forwarding plane, which, by observing the performance of Interest/Data exchange, can dynamically select the best performing forwarding path, detect and recover from failures,...
CGEA (Convergence Gradients Expectation Ant algorithm) is proposed in this paper, which can get the optimal path quickly by precomputing the Convergence grads expectation of improved ant algorithm. QoS metrics of link can be measured by expectation function and the optimal path can be got efficiently by comparing the convergence grads.
Modern distributed service-oriented networks are complex heterogeneous systems. This includes cloud network. To solve synthesis problems of distributed service-oriented structures an algorithm of conformal mapping topology that is based on the definition of hyperbolic virtual coordinates has been proposed. This algorithm requires less iterations than other methods and is able to provide guaranteed...
Network routers use dynamic routing protocols to learn remote networks automatically. Each routing protocol has its own pros and cons when considering administration, maintenance, metrics, convergence time, backup routes, network complexity and size, scalability, resource requirements and so on. RIP is the simplest routing protocol, which is supported by almost all routers and many operating systems,...
The wide deployment of Wireless Sensor Networks along with the proliferation of applications that use WSN-generated data has led to the design of WSN architectures and systems that support multiple applications over the same WSN infrastructure. Different Quality of Service requirements imposed by different applications impose the use of appropriate routing metrics to decide the data path. Although...
Algebra has made the tasks of defining routing algorithms and proving their correct operation very clear. However, current results in the modelling of multipath policy routing protocols only prove correct behaviour for models that exhibit a strict decrease in the preference of a path with every added link. This is very rigid for multipath routing. For instance it does not allow a link attribute to...
Confronted to the increasing dynamic of Internet routing system and its underlying topology, we propose a reliability and availability analysis method based on the characterization of the dynamic properties (in particular, the stability properties) of routing paths and their corresponding forwarding paths. The key driver underlying this method is that transient but frequent changes in the spatio-temporal...
In this paper, we propose a new gossip-based signaling dissemination method for the Next Steps in Signaling protocol family. In more detail, we propose to extend the General Internet Signaling Transport (GIST) protocol, so as to leverage these new dissemination capabilities from all NSIS Signaling Layer Protocol applications using its transport capabilities. The extension consists of two main procedures:...
Selection of a Dynamic Routing Protocol has great impact on the utilization of various network resources. The factors like usage of bandwidth and behaviour towards growing entries in the routing table, determine the suitability of a protocol. In this paper, we have measured and compared the bandwidths utilised by the three IPv4 dynamic routing protocols, RIPv2 (Routing Information Protocol), EIGRP...
In this paper we show data plane restoration measurements for restoration under backbone link failures for a large network with IP/MPLS OSPF routing and also for the same backbone with Traffic Engineering (TE) and Fast Reroute (FRR) deployed. Our study is unique as we analyzed a significant quantity of measurements obtained from a production network over a 14-month period encompassing many link failures...
The Border Gateway Protocol (BGP) is the de facto interdomain routing protocol on the Internet which controls the packet forwarding behavior on the data plane. It has significant impact on the well-being of the global Internet. Over the past ten years, there has been a large body of studies conducted on evaluating and improving the BGP performance. These studies develop tools using BGP data for identifying...
This paper presents th implementation decisions to be made when th choice is between protocols that involve distance vector or link state or the combination of both. Here a comparison is made between different parameters and a detailed simulation study is performed on the network with different routing protocols and it has been shown that EIGRP provides a better network convergence time, less bandwidth...
High rate and high quality of service as well as multi-technology connections are the key words for the future home networks. For this goal, we introduce a new convergence layer denoted inter-MAC, which provides a common infrastructure to the home network at layer 2. Among the inter-MAC functionalities, we focused our interest on the path selection mechanism. To improve quality of service, we define...
