We present Anomalous Packet Detection using Partitioned Payload system, we call as AnPDPP. AnPDPP is an improvement to PAYL system which is considered one of the complete systems for payload based anomaly detection. PAYL takes into consideration the entire payload for profile calculation and effectively for anomaly detection. Payload length is very high on port numbers like 21 and 80. Hence it ...

We study Smith-Purcell radiation from a conducting grating generated by an inclined passage of shaped electron wave packet with electric quadrupole moment in the nonparaxial regime. Spreading asymmetric induces corrections to field. Although stay small, they are dynamically enhanced during interaction whose length exceeds Rayleigh packet. To simplify possible experimental setup where such effec...

Packet classification is important in fulfilling the requirements of new services such as policy-based routing in next generation networks. In this paper, we propose a novel bit vector based two-dimensional packet classification algorithm called Group Bit Vector. The key feature of the proposed algorithm is its ability to set the length of the bit vector to perform AND operation (the operation ...

We consider the problem of approximating the frequency of frequently occurring elements in a stream of length n using only a memory of size m ≪ n. This models the process of gathering statistics on Internet packet streaming using a memory that is small relative to the number of classes (e.g. IP addresses) of packets. We show that when some data item a occurs αn times in a stream of length n, th...

The power saving class of type II (PSC II), one of the sleep mode operations in the IEEE 802.16e standard, is designed to reduce power consumption for unsolicited grant service (UGS) and real-time variablerate (RT-VR) connections. However, the configuration of fixed-length listening windows in the PSC II incurs unnecessary energy consumption or packet loss for these types of connections. In ord...

A translation-invariant denoising method, based on the Minimum Description Length (MDL) criterion and the Shift-Invariant Wavelet Packet Decomposition (SIWPD) is presented. A collection of signal models is generated using an extended library of orthonormal wavelet-packet bases, and an additive cost function, approximately representing the MDL principle, is derived. We show that the minimum desc...

This study presents a selective data-compression interconnection network to boost its performance. Data compression virtually increases the effective bandwidth. One drawback of data is long latency perform (de-)compression operation at compute node. In terms communication latency, we explore trade-off between overhead and reduced injection by shortening packet length algorithms. As result, pres...

Traffic sampling technology has been widely deployed in front of many high-speed network applications to alleviate the great pressure on packet capturing. However, knowing the number and length of the original flows is necessary for some applications. This paper provides a novel method that uses flow statistics formed from sampled packet stream to infer the absolute frequencies of lengths of fl...

Fair queueing is a useful queueing discipline for packet switching systems. It was developed in last decade and was aimed at the general packet switching systems with varying packet length. However, it is not suitable for use in the ATM networking, because the ATM cell length is very small and fixed, and so the scheduling scheme on a per cell basis isn’t practical. Here we introduce the burst a...
