Meeting the service demands from QoS-based network applications is a very challenging task performed in many high-end routers and switches. This task involves management of resources like bandwidth and memory in network devices. The memory in the form of a very fast cache that instruments wire-speed classification, discrimination, and forwarding of network packets needs to be managed very effec...

One of the key design issues for the new generation IP routers is the route lookup mechanism. For each incoming IP packet, the IP routing requires to perform a longest prefix matching on the address lookup in order to determine the packet’s next hop. This paper presents a fast route lookup mechanism that only needs tiny SRAM and can be implemented in a pipelined skill in hardware. Based on the ...

We propose DMP-tree, a dynamic M-way prefix tree, data structure for the string matching problem in general and prefix matching in particular. DMP-tree has been initially devised for fast and efficiently handling prefix matching which constitutes the building block of some applications in the computer realm and related area. It is assumed there are strings of an alphabet R which are ordered. Th...

Physical layer security (PLS) and simultaneous wireless information power transfer (SWIPT) in cooperative relaying have gained great interest as technologies for energy enhancement Internet-of-Things (IoT) networks. In this work, we investigate PLS a SWIPT- AF-enabled IoT system, consisting of one source, multiple harvesting (EH) relays, destination, the presence an eavesdropper that tries to o...

We propose an efficient design flow for the automatic synthesis of Networkon-Chip (NOC) topologies. The specification of the problem is given as a netlist of IP cores and their communication requirements. Each IP is characterized by its area. A communication constraint is denoted by its source and destination IP and a minimum bandwidth requirement. Together with the specification, the users pro...

We develop a formal statistical approach to investigate the possibility that leading indicator variables have different lead times at business cycle peaks and troughs. For this purpose, we propose a novel Markov switching vector autoregressive model, where economic growth and leading indicators share a common Markov process determining the state, but such that their cycles are non-synchronous w...

A general model is made to analyze switching throughput of traffic manager in core routers. By designing a real traffic manager that uses the OC-48c interface, the whole system is analyzed and it is pointed out that at least four HSSLs should be employed per CSIX interface when using Vitesse’s GigaStream switch chipset. Meanwhile, at the CSIX interface, the CFrame should be constructed accordin...

Next Generation Networks (NGN) is a strategy to achieve the vision of next-generation services for the delivery of quad play data, voice and video anywhere and anytime virtually across any access technology. It integrates the services of 2G/3G/4G Networks including IPv4 and IPv6 and incorporates the services of traditional networks into a single service platform with the usage of Multi-Protocol...

MPLS is highlightened as the most promising technology for the integrated IP-over ATM backbone networks. Nowadays, one of the important practical issues in MPLS is the capability to provide Differentiated Services. For integrating IP and ATM with scalability, MPLS based ATM switch network can be available, especially for the fast Internet services adding Layer 3 routing module to the existing A...

This paper presents a live-video service using multicast in wireless network. The switching/multicast agent (SMA) in this system provides multicast for effective use of network resources in WLAN and reduces the load of video server and access points(AP). Also, the SMA and AP support a handover mechanism for moving mobile nodes(MN) using identification number(ID#) of AP (AP_#) that the MNs are v...
