TELE 5330 – DATA NETWORKING

ASSIGNMENT #2 Name: Prashanth Reddy Edunuri

(1) Most applications that use peer-to-peer communication also employs client server communication for some portion of functionality as decentralized peer-to-peer networks have numerous compensations over old-fashioned client-server networks. This system endorsed files to be questioned and shared between users, devoid of a central directory, and as a result shielded the network from lawful issues of individual users. By decentralizing resources, P2P networks have been able to virtually exclude expenses allied with a centralized infrastructure. Peers are directly connected to each other for file transfer.

SSL technically resides in the application layer, from the developer’s outlook it is a transport-layer protocol.

FTP-File Transfer Protocol TFTP-Trivial File Transfer Protocol
It is used to transfer files from one computer to another over a TCP network. It is used to transfer files between remote machines over a UDP network.
It is defined by RFC 959. It is defined by RFC 1350.
It uses a client-server architecture. After establishing an FTP connection, the user can download or upload files to and from the FTP server. It is a simple version of FTP, lacking some more advanced features FTP offers. It can be used only to send and receive files.
FTP uses two TCP ports. Port 20 for sending data and port 21 for sending control commands. It uses UDP port 69 for communication.
FTP can use authentication and all data is sent in clear text. TFTP doesn’t support user authentication and sends all data in clear text.

HTTP 1.0 HTTP 1.1
It is defined by RFC 1945. It is defined by RFC 2616.
HTTP 1.0 could only define up to 16 status codes which results in poor resolution and has some limitations. HTTP 1.1 came up with 24 status codes that were able to solve the previous limitations. It has a warning header capable of producing many secondary status

    Hadoop [8] is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node. The jobtracker assigns the tasks to the tasktrackers running on many slave nodes or on a cluster of machines.

    5. METHODOLOGY 5.1 Secure Multipath Routing Protocols in Wireless Sensor Networks Till date many routing protocols have been proposed for wireless sensor networks, but only few of them consider the problem of security [4] and most of them are developed without any security concern. So in this section we focus at selected multipath routing protocols in order to cope with the various attacks. For avoiding intruders attacks in HWSN various methods and algorithms are implemented out of that Professor Hamid Al-Hamadi and Professor Ing-Ray Chen:

    I am going to explain the current methods and protocols we use in a LAN environment to provide a high level of redundancy, such as EtherChannel, FHRP (First Hop Redundancy Protocols) and STP (Spanning Tree protocols). I will briefly explain how the protocols work & then discusses the latest implementations of the protocol and the environment you would expect to see them working in. The STP is a protocol that prevents loops from occurring in a switched LAN environments when a device has multiple interconnected paths. The protocols works by sending BDPU messages across in the interconnected devices, detects the loop then removes it from the topology by shutting down the port.

    The research study includes two measurements, the Progressive Aerobic Cardiovascular Endurance Run (PACER) test and the Situational Motivation Scale (SIMS). The first focus of the clinical experience assignment was to observe the guidance counselor administer the SIMS questionnaire to students. Two fifth grade classes were observed; students in both classes participated in a second steps teambuilding activity prior to completing the SIMS questionnaire. One of the objectives for this clinical experience was to observe how the guidance counselor administered the questionnaire. After the teambuilding activity, students in both classes received detailed instructions from the counselor on how to complete the questionnaire.

    Other protocols such as secure socket layer (SSL) which operates at the transport layer enable server authentication as well as client authentication and encrypted communication. Using SSL, we could ensure that the information being sent from our companies’ server and any remote clients is secure. However, it is worth pointing out that SSL has a successor known as transport layer security (TLS). As a successor to SSL functionality, wise TLS is very similar. Some of the improvements made in TLS at least TLS v1.2 include less vulnerabilities compared to SSL as well as new algorithm’s .

    In general, all the predators and prey (regardless of habitat) began with the same amount of population. For instance, there are a total of six predators (2 had forks, 2 had spoons, and 2 had knives)—regardless of habitat, Meaning each predator contributed to 33% of the population (Tables 1A, 2A). For prey, each bean contributed 25% of the population (Tables 1B, 2B). However, as generation progressed, differences began to appear.

    Both types of networks provide network services using operating systems that can communicate with each other through common protocols. Each of these networks enables control of how users and programs get access to resources. Also, clients in a client server network and nodes or hosts in a peer-to-peer network use any combination of desktop, mobile, or tablet operating systems. 2.

    1Dear Principal Molony, The donated money should be used in the eight grade math and reading classrooms because it will improve the focus and attention of the students. The students' self esteem will go up which will let them participate and do more to benefit the classrooms. They will also be less antsy because they will be focused on work, and not worrying about their uncomfortable seats. Here is what the seats are going to be like: there will be three couches, four to five bean bags, three wiggle seats, one recliner and two big tables the wiggle seats will go on the table chairs.
