Information Centric Networks(ICN) can employ per-node forwarding strategies to provide an optimal transport service. This paper describes the design of an ICN Forwarder that implements Application-Adaptive Forwarding(AAF): an optimized multipath forwarding strategy for differentiated services that can adapt dynamically to changing link characteristics and implement different operator policies with...
Ensuring network interoperability when IEEE 802.11s-based NAN and LTE-based WAN is deployed for Smart Grid (SG) Advanced Metering Infrastructure (AMI) poses significant challenges. Besides the QoS mismatch between networks, LTE tunneling mechanism becomes an issue when forwarding downlink traffic to IEEE 802.11s network since the gateway of these networks is supposed to be the end device in LTE setup...
Hash computation is an important component of many high speed network devices that employ them for longest prefix matching. With growing line rates it is essential that this critic l component be implemented in hardware to reduce both power and latency. In this paper, we focus on the issue of latency. Null Convention Logic (NCL) is a popular asynchronous design technique that is known to offer robustness...
This work presents a binary counter that was derived using the basic theory of 1D Cellular Automata. One of the 1D Cellular Automata seeds is producing an evolutionary structure in which the sequence of binary numbers is reproduced in selective bit positions. The main characteristic of this counting sequence is that it is produced with low complexity with a small penalty of information redundancy...
This paper investigates the wireless mesh IP video surveillance models and evaluates their performance in terms of throughput, End-to-End delay and jitter. Wireless Mesh Network consists of either a wireless or wired backbone network from which Mesh Gateways (MGs), Access Points (APs), wireless Mesh Routers (MRs) and Mesh Client (MCs) are linked together through carefully designed topologies. WMN...
When statistical multiplexing is used to provide connectivity to a number of client hosts through a high-delay link, the original TCP as well as TCP variants born to improve performance on those links often provide poor performance and sub-optimal QoS properties. To guarantee intra-protocol fairness, inter-protocol friendliness, low queues utilization and optimal throughput in mission-critical scenarios,...
A previously developed plug-in architecture for network-virtualization nodes allows network operators to introduce new types of virtual nodes and links and slice developers to use them in slices (i.e., virtual networks). In this paper, a method for extending network-virtualization infrastructures by introducing plug-ins to nodes in the infrastructure and a freely-designed plug-in-specific packet header,...
Network Address Translation (NAT) is the major solution to solve IP address shortage. However, NAT breaks the peer-to-peer communications and the Internet-oriented requests. In order to resolve this problem, lots of NAT traversal solutions such as Session Traversal Utilities for NAT (STUN), Universal Plug-and-Play (UPnP), Traversal Using Relay NAT (TURN), Application-Layer Gateway (ALG) and Interactive...
LTE (Long Term Evolution) is becoming the fastest growing mobile communications technology ever. IEEE 802.11 and IEEE 802.15 standards is also developing on the other side. IEEE 802.11 standards (WLAN-Wireless Local area Network) provides higher data rates and less coverage. In the next generation networks, it is very important to increase the coverage area and efficiency of WLAN standards. Hence...
Wireless mesh network (WMN) forms a wireless backbone which extend the coverage area via multi-hop relay function. The performance of WMNs can be further boosted by employing multiple gateways. In this paper, we address the implementation issues for deploying WMN test bed with multiple gateways and propose a channel load aware airtime(CL_AIR) metric based path and gateway selection scheme to balance...
Traditional IP based networks, Frame Relay and ATM networks have many disadvantages in the management operation of large networks such as cost, security, scalability and flexibility. To solve this, an MPLS-based VPN networking is introduced that can work with existing deployed backbones and allow organizations to interconnect the dispersed sites and remote workers through secure links by using public...
In this paper, the authors present a study of a network fingerprinting classification using monotone multilayer perceptron neuronal networks. It is part of an overall performance engineering approach. The classification is used to increase the performance of an active queue management on the quality of service for a next generation public safety communication system based on an IP overlay network...
Existing gateway selection mechanisms base their selection on gateway load and/or geographical proximity of users to the gateways. In this paper, we mainly argue the need for other metrics to improve the gateway selection mechanisms in distributed mobile networks. We therefore propose considering the end-to-end connection and the service/application type as two important additional metrics in the...
A Network Address Translator (NAT) allows hosts in a private address space to communicate with servers in the public Internet. There is no accepted solution for an arbitrary host in the Internet to initiate a communication with a host located in a private address space despite the efforts to create one. This paper proposes to replace NATs with a new concept we call Private Realm Gateway (PRGW). Private...
