This document describes troubleshooting three network connectivity problems at OCP Enterprises. Problem 1 was that PC1 could not reach PC4, which was caused by R2 missing a route to network 1 in its routing table. Problem 2, that PC1 could not reach devices on network 3, was also due to this missing route. Problem 3, that only PC1 and PC3 but not PC2 could reach network 3, was found to be due to PC2 having an incorrect default gateway and IP address configuration.

Design and implementation of log domain decoder IJECEIAES
Low-Density-Parity-Check (LDPC) code has become famous in communications systems for error correction, as an advantage of the robust performance in correcting errors and the ability to meet all the requirements of the 5G system. However, the mot challenge faced researchers is the hardware implementation, because of higher complexity and long run-time. In this paper, an efficient and optimum design for log domain decoder has been implemented using Xilinx system generator with FPGA device Kintex7 (XC7K325T-2FFG900C). Results confirm that the proposed decoder gives a Bit Error Rate (BER) very closed to theory calculations which illustrate that this decoder is suitable for next generation demand which needs a high data rate with very low BER.
A NOVEL APPROACH FOR LOWER POWER DESIGN IN TURBO CODING SYSTEMVLSICS Design
Low Power is an extremely important issue for future mobile communication systems; The focus of this paper is to implementat turbo codes for low power solutions. The effect on performance due to variation in parameters like frame length, number of iterations, type of encoding scheme and type of the interleave in the presence of additive white Gaussian noise is studied with the floating point model. In order to obtain the effect of quantization and word length variation, a fixed point model of the application is also developed.. The application performance measure, namely bit-error rate (BER) is used as a design constraint while optimizing for power and area coverage. Low power Optimization is Performed on Implementation levels by the use of Voltage scaling. With those Techniques we can reduced the power 98.5%and Area(LUT) is 57% and speed grade is Increased .This type of Power maneger is proposed and implemented based on the timing details of the turbo decoder in the VHDL model.
DDoS attacks have become one of the most dangerous issues in the Internet today. Because of these attacks, legitimate users can not access the resources they need. In [1] authors proposed a combined method for tracing and blocking the sources of DDoS-attacks. The essence of the method is that each router marks the network packet that passes through it using a random hash function from the set. At the receiving side this information is stored and used to filter unwanted traffic and traceback the source of distributed attack. This article describes the simulation and its results of the combined method.
The document provides the questions and answers for CCNA 1 Chapter 5 exam. It tests knowledge of ARP, MAC addresses, switching, Ethernet, and other networking concepts.

The Internet Protocol version 4 (IPv4) is the delivery mechanism used by the TCP/IP protocols. IPv4 is an unreliable and connectionless datagram protocol & a best-effort delivery service means that IPv4 provides no error control or flow control (except for error detection on the header). IPv4 assumes the unreliability of the underlying layers and does its best to get a transmission through to its destination, but with no guarantees.ThesisScientist.com

A 2 stage data word packet communication decoder using rate 1-by-3 viterbi de...eSAT Journals
Abstract
In the field of consumer electronics the high speed communication technology applications based on hardware and software control are playing a vital role in establishing the benchmarks for catering the operational requirements of the electronic hardware to fulfil the consumer requirements in wired and wireless communication. In the modern era of communication electronics decoding and encoding of any data(s) using high speed and low power features of FPGA devices [1] based on VLSI technology offers less area, hardware portability, data security, high speed network connectivity [2], data error removal capability, complex algorithm realization, etc. Viterbi decoder is a high rate decoder that is very commonly and effectively used method in modern communication hardware. It involves Trellis coded modulation (TCM) scheme for decoding the data. The viterbi decoder is an attempt to reduce the power, speed [1], and cost as compared to normal decoders for wired and wireless communication. The work in this paper proposes a improved data error identification probability design of Viterbi decoders for communication systems with a low power operational performance. The proposed design combines the error identification capability of the viterbi decoder with parity decoder to improve the probability of the overall system in identifying the error during the communication process. Among various functional blocks in the Viterbi decoder, both hardware complexity and decoding speed highly depends on the architecture of the Decoder. The operational blocks of viterbi decoder are combined with parity testing block to identify the error in the viterbi decoded data using parity bit. The present design proposes a multi-stage pipelined architecture of decoder. The former stage is the viterbi decoding stage and the later stage is the parity decoding stage for the identification of error in the communicated data. Any Odd number of errors occuring in the recovered data from the former decoding stage can be identified using the later decoding stage. A general solution to derive the communication using conventional viterbi decoder is also given in this paper. Implementation result of proposed design for a rate 1/3 convolutional code is compared with the conventional design. The design of proposed algorithm is simulated and synthesized successfully Xilinx ISE Tool [3] on Xilinx Spartan 3E FPGA.

IPv4 and IPv6 are network layer protocols that route packets between networks through multiple hops. The network layer addresses devices, routes packets, and interconnects different subnets. Routers use routing tables to forward packets towards their destination network based on the destination address. Fragmentation allows packets to be split into smaller pieces if their size exceeds the maximum transmission unit on a link. This allows packets to traverse heterogeneous networks with different MTU sizes.
