Why hierarchical routing is employed in Internet? 2.2.What are the two major jobs of inter-AS routing? 2.3.What is hot potato routing? 2.4.What are the major differences between RIP and OSPF?
Solution
2.1why hierarchical routing is employed in internet
Hierarchical routing is the procedure of arranging routers in a hierarchical manner. A good example would be to consider a corporate intranet. Most corporate intranets consist of a high speed backbone network. It decreases the complexity of network topology, increases routing efficiency, and causes much less congestionbecause of fewer routing advertisements. When the network size grows, the number of routers in the network increases. Consequently, the size of routing tables increases, as well, and routers can\'t handle network traffic as efficiently. We use hierarchical routing to overcome this problem.
2.2 two major jobs of inter AS routing
Inter As routing propagates reachability info to all internal router.
To configure the forwarding table, router 1d must determine towards which gateway it should forward packets for dest..
2.3 What is hot potato routing
Hot potato routing is a routing technique enabling packet routing without storing them in buffers. Instead, this technique continuously transfers data packets until they reach their destination without the packets having to wait or be stored in a buffer. It is the practice of passing traffic off to another autonomous system as quickly as possible, thus using their network for wide-area transit.
This technique is most commonly used in optical networks where messages cannot be stored in any medium. Hot potato routing is used when individual communication links cannot support more than one packet at a time.
Hot potato routing is also known as deflection routing.
2.4 Difference between RIP and OSPF
Both RIP and OSPF are examples of interior routing protocols. RIP stands for Routing Information Protocol and OSPF stands for Open Shortest Path First.
RIP is a distance vector protocol and OSPF is a link state protocol.
In RIP protocol, networks are not divided in areas or tables. The metrics used in OSPF are bandwidth and delay.
In RIP maximum hop count is 15. In OSPF no hop count.
In RIP protocol, networks are not divided in areas or tables. In OSPF, routing is carried out in autonomous system, into areas, sub areas as well as backbone areas.

Different Routing protocols
This thesis presents a simulation based analysis of these protocols. We used the combination of EIGRP&IS-IS, RIP&IS-IS routing protocols on the Hybrid network in order to reveal the advantage of one over the other as well as the robustness of each protocol combination and how this is measured.
Analysis of RIP, EIGRP, and OSPF Routing Protocols in a Network
There are many routing protocols out there today, some old and some new, but all are used for the same purpose. In general, to ideally select routes between any two nodes on a computer network and disseminate information. Routing of data packets is one of the important process in the internet. A routing protocol specifies the method of communication among routers used in the inter connection of networks. This paper takes into consideration three of such routing protocols RIP, OSPF, and EIGRP , expresses them and analyzes their way of operation. In this paper, we have analyzed and simulated a proposed Local Area Network using different routing protocols. So, configuration of these different routing protocols are done using CISCO packet tracer simulator.

Network Performance Analysis of Dynamic Routing Protocols for Real Time Appl...
Routing protocol is taking a vital role in the modern internet era. A routing protocol determines
how the routers communicate with each other to forward the packets by taking the optimal path to travel
from a source node to a destination node in the network layer. Algorithms that are used for route selection
and data structure are the main parts for the network layer. But in this paper we have explored four
eminent dynamic routing protocols namely, Routing Information Protocol (RIP), Open Shortest Path First
(OSPF) & Enhanced Interior Gateway Routing Protocol (EIGRP) and Interior Gateway Routing Protocol
(IGRP) protocols. Evaluation of these routing protocols is performed based on the quantitative metrics
such as Delay, FTP, E-mail, HTTP, VoIP and Video Conferencing through the simulated network models.
The simulation results are analyzed, with a comparison between these protocols on the effectiveness and
performance in network implemented. Results show that EIGRP will be best for delay, E-mail and FTP but
for real time applications OSPF and RIP give better results

In modern network communications, Routing protocols are getting an important function for the user data path that are responsible for controlling the routers to communicate together and forward packets by routers over the best trip path from a base node to a destination one. Dynamic routing protocols represented by RIP, OSPF and EIGRP are explained here for addressing various networks with different traffic environments. In this paper, the performance of these protocols are estimating with many factors like convergence activity and duration, average throughput, network end-to-end delay, Point-to-Point Utilization over the simulation based on OPNET academic version. From Simulation results, EIGRP have a fastest time convergence compared with other topologies of networks are confirmed and the OSPF has the highest Point-to-Point Utilization in the network followed by EIGRP then RIP. So, there is an attempt for finding out which protocols are suitable for the networks and from analyses to understand the role of the routing protocols in different network scenarios

A Comparative Performance Analysis of Route Redistribution among Three Differ...
In an enterprise network, it is normal to use multiple dynamic routing protocols for forwarding packets.
Therefore, the route redistribution is an important issue in an enterprise network that has been configured
by multiple different routing protocols in its routers. In this study, we analyse the performance of the
combination of three routing protocols in each scenario and make a comparison among our scenarios. We
have used the OPNET 17.5 simulator to create the three scenarios in this paper by selecting three different
routing protocols from the distance vector and link state routing protocols in each scenario. In the first
scenario, the network routers are configured from EIGRP, IGRP, and IS-IS that is named
EIGRP_IGRP_ISIS in our simulation. The OSPF_IGRP_ISIS scenario is a mixed from EIGRP, IGRP, and
IS-IS protocols that is the second scenario. The third scenario is OSPF_IGRP_EIGRP that is the route
redistribution among OSPF, IGRP, and IS-IS protocols. The simulation results showed that the
performance of the EIGRP_IGRP_ISIS scenario is better than the other scenarios in terms of network
convergence time, throughput, video packet delay variation, and FTP download response time. In contrast,
the OSPF_IGRP_ISIS has less voice packet delay variation, video conferencing and voice packet end to
end delays, and queuing delay as compared with the two other scenarios. On the other hand, the
performance of the OSPF_IGRP_EIGRP scenario has better FTP upload response time, and voice jitter.

Routing protocols can be the Interior Gateway Protocol (IGP), which is for you internal networks and the exterior routing protocol is Exterior Gateway Protocol (EGP). This protocol maintains the routing information for networks (external) to your network. It only knows how to deliver data outside your network. EGP does not know how to deliver data within your network. Border Gateway Protocol (BGP) is the only EGP in use today. BGP is the routing protocol for the Internet.
Open Shortest Path First (OSPF) is starting to become the popular interior routing protocol (Tiso, 2011). If designing a new network, I would recommend OSPF or EIGRP because of the popularity, flexibility, and fast convergence. Reason I say OSPF is because there is not limitation on the hop count like there is with RIP (15). OSPF uses IP multicast to send link-state updates ("Cisco," 2014). Updates sent when routing changes occur instead of periodically. Better convergence since routing changes is instantaneously and not periodically.
My experience with OSPF occurred back in 2003 when a team I was working with was task to put in a new video teleconference network for an intelligence agency that consisted of over 250 rooms moving from H.320 to H.323. The network would consist of CONUS and OCONUS. Fourteen years later, equipment has been upgraded routers, switches, endpoints, etc. but the same routing protocol still used.

Enhanced Interior Gateway Routing Protocol (EIGRP) is Cisco's proprietary routing protocol, based on IGRP. EIGRP is a distance-vector routing protocol, with optimizations to minimize routing instability incurred after topology changes, and the use of bandwidth and processing power in the router. Routers that support EIGRP will automatically redistribute route information to IGRP neighbours by converting the 32-bit EIGRP metric to the 24-bit IGRP metric. Most of the routing optimizations are based on the Diffusing Update Algorithm (DUAL), which guarantees loop-free operation and provides fast router convergence.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Discuss the importance of using a routing protocol, and explain its .docx
- 1. Discuss the importance of using a routing protocol, and explain its general functionality. Router Information Protocol (RIP) is a distance-vector routing protocol, while Open Shortest Path First (OSPF) is a link-state routing protocol. Either can be used by a router to send data from one network to another. Compare and contrast distance-vector versus link-state routing protocols. Explain how you would enable OSPF. Complete the following for this assignment: Using the course materials, the textbook, and Web resources, research distance-vector routing protocols with a high concentration on the versions of RIP. Use the following questions to help you format your research paper: What is the purpose of a routing protocol, and how does it differ from a routed protocol? What is a distance-vector routing protocol? What is a link-state routing protocol? What are the advantages and disadvantages of distance-vector protocols? What are the advantages and disadvantages of link-state protocols? What is RIP? What is OSPF?
- 2. What are the 2 versions of RIP, and what are their specific purposes? When would you employ RIP, and when would you employ OSPF? Describe what is necessary to enable OSPF routing. Compile your responses to the above questions in a Word document of 3–5 pages. Your submitted assignment must include the following: A Word document of 3–5 pages, double-spaced, excluding the title page and reference section. All references should be in APA format.
