In the digital era is , the internet becomes a necessity . the increasing number of internet usage by various parties encourages ISPs to improve their service quality . To overcome the problem the IETF has introduced a service Multiprotcol . MPLS-TE allows for schemes TE where the tip router of the label switched path (LSP) can calculate the many routes efficiently through the network to the router tip of the tail of the LSP. TE consists of three steps principal that is the size , model, and control . MPLS-TE allows for schemes TE where the tip router of the label switched path (LSP) can calculate the many routes efficiently through the network to the router tip of the tail of the LSP. ISIS is one of the routing protocol that was created for the OSI mode, using the method of link state as a method of collecting the route , ISIS also will perform the collection of information and the status of all the links that exist in the network . Analysis of the IS-IS routing protocol with the Multiprotocol label switch Traffic Engineering based on the parameters of quality of service (QoS), namely throughput and packet loss where the simulation uses the GNS3 network emulator. The test results prove that the values of throughput and packet loss are not much different.

The Difference

In a dynamic routing setting a routing protocol is required to perform the settings to find the shortest and best path. Routing protocols are of two types: vector distance and link state. Use of EIGRP routing that includes long-range vectors and link state OSPF Link link state coverage, peg well to be implemented in complex network because it can adapt well. In this research is the method used for routing and speed of time available EIGRP routing and OSPF routing through simulator GNS3 and wireshark application, then analyze the difference of peformance with speed of routing table and speed of time. While for Quality of Service (QoS) compare network service quality from EIGRP and OSPF routing which include delay, packet loss, and throughput. Based on the results of the research shows the EIGRP routing table is better in the selection path, EIGRP smaller time tansfer data then its data transfer faster than the OSPF. Overall Quality Of Service (Qos) delay, packetloss and throughput on EIGRP and OSPF are well balanced and good.

AbstractIf my discernment of the thought that underlies his study of Nuer religion is not entirely misconstrued, then one can assert a logical consistency between Collingwood's methodology for history and Evans-Pritchard's for ethnography. It is worthwhile, in that light, to consider the fact that "at one time Evans-Pritchard contemplated writing Collingwood's biography" (Beidelman 1974:559). One commentator, (Kuper 1980:118) typifies this methodology as "postwar idealism" and suggests that the major works he published in the later decades of his presence at Oxford demonstrate the "sterility" of his methodology and theory. Still others have hinted that his entry into the Catholic Church was later reflected in his depiction of Nuer religous life. These are remarkable assertions, when one takes the time to reflect on the many ways in which his own approach and writings have so profoundly influenced the direction of anthropological enquiry in his own country and abroad. The fact is, one can no longer write ethnography in lieu of a solid understanding of the historical circumstances which have resulted in the contemporary 'ethnographic present'. At the same time, practitioners of the discipline have addressed from almost every angle the proposition that all ethnography is indeed a good part confession-that we write what we are able to see. That is precisely the quality of the work that will guarantee the status of Nuer religion as a classic. The methods of history and anthropology can only become more similar. Anyone who holds an absence of definition or presumed repugnance toward theory as criticisms of his contributions, has truly lost the forest for the trees. It is all the more remarkable that his methodological and theoretical advances in the anthropological study of religion are to be found not in his answers, but in the questions he raised.10

Wiki is a typical representative of the User-Generated Content. Its appearance greatly promotes the creation, organization, management, and sharing of knowledge on the Internet. As articles grow rapidly in Wikis, the quality of the articles has aroused many people’s concerns. The topics on how to assess and control the quality of articles have attracted many researchers. However, few studies have been conducted to investigate the status of this research topic. This chapter explores the current research status and trends of wikis' quality and governance. The authors selected papers from the databases of ISI, EI, IEEE, and other widely used databases. They reported the trends and research of wikis’ quality and governance using bibliometric analysis and content analysis of a total of 99 relevant papers. The results show that although the research topics in the field have experienced a very rapid development, they are still at an early age that lacks theories to support them. The discipline of Library and Information Science was found to play a very active role in this new area. Future research agenda and directions are also discussed.

Quality Of Research

The past twenty-five years have seen an enormous growth in research into World Englishes, reflecting a new recognition of the status of the many national English dialects. Canadian English has been no exception to this trend and we have witnessed a dramatic increase in the quantity and quality of research into this variety. The stature it is now accorded as a separate dialect of English is reflected in the number of dictionaries, thesauruses, usage guides, and other reference works published since the late 1990s that were devoted specifically to Canadian English (e.g., Guide to Canadian English usage; Canadian Oxford dictionary; Oxford Canadian Dictionary; Collins essential Canadian English dictionary and thesaurus; Fitzhenry and Whiteside Canadian thesaurus) as well as audio-visual productions (e.g., Dialects of Canadian English; Talking Canadian).

Diffserv-aware and Traffic Engineering combine the advantages of MPLS, Traffic Engineering (TE) and Differentiated Services (Diffserv, DS) to provide high performance and Quality of Service(QoS) in networks. We have designed three scenarios on Juniper Networks platforms to analyze the packet loss rate and delay for video, voice and data. The results show that MPLS DS-TE can improve the QoS for differentiated service effectively. The research has practical value for the development of DS-TE based on MPLS.

Aging is a stage of life that increases the risk of physical diseases, some of which are chronic and can affect different dimensions of life’s quality and the status of psychological factors in these patients. In addition to medical supports, it is essential to provide sport complexes in accordance with the physical and mental condition of these patients. The aim of this study was to evaluate the effect of a period of aquatic therapy exercise on the quality of life and depression in aged males suffering from chronic physical pains.In a semi-experimental study, 30 aged males who voluntarily referred to Niyayesh health center of Shiraz were selected. They were randomly divided in to two groups; experimental (n=15) and control (n=15). Subjects of aquatic therapy exercise were involved in an 8-week-activity in water; 3 sessions per week each lasting approximately 50 to 70 minutes. At the same time, the control group was only followed-up and was not engaged in any exercise during this period. The variables of the quality of life and depression among the patients were measured by standard questionnaires in the beginning and end of the eight-week-aquatic therapy exercise. Results of this study showed that aquatic therapy exercise can be used as an effective and helpful method to promote public health in aged males suffering from chronic physical pains because it leads to the improvement of multi-dimensional variables of quality of life and depression in the patients.

Multi Point Relays (MPRs) are those nodes that are calculated and determined by the Optimized Link State Routing protocol (OLSR) in order to minimize and avoid overload inside the Mobile Ad hoc Network (MANET). In this paper, we will present a synthetic study of many techniques and methods for calculating and selecting the MPR nodes using a set of criteria namely energy, mobility, bandwidth, the quality of links, etc. The result of this study shows that most techniques consider a limited number of metrics for selecting the MPR nodes and therefore they are insufficient to allow the OLSR protocol to be quite complete and efficient because several metrics can occur at the same time in the real execution environment.

As an institution engaged in SMK Muhammadiyah 03 Yogyakarta  requires network infrastructure as a medium of communication. Infrastructure in SMK Muhammadiyah based VLAN but still using static routing and star topologies as a medium of communication between router. This leads to the main router performance overburdened  which makes the network infrastructure down. It is necessary to reform the network, especially in the communication protocol on the router by using protocol Open Shortest Path First(OSPF). OSPF is a link state-based routing protocol that uses Dijkstra’s algorithm to find the best path is taken as a communication medium. Makin paths made by considering various aspects of the parameters that affect network traffic. OSPF can minimize down on network infrastructure caused by the buren of a huge traffic to maintain the stability of traffic on communication lines. The results using the method QOS on infrastructure with the OSPF protocol can be classified very nice. It is obtaine from the measurement parameter delay <150 ms, packet loss (0%), an bandwidth has a very goo category based on the standard TIPHON. From the results of the QOS parameters also obtained a decrease in delay value by 31% on infrastructure with the OSPF protocol. This proves that the network traffic is more stable when using OSPF protocol.

This work aims at giving an updated vision on the successful combination between Metaheuristics and Software Engineering (SE). Mostly during the 90s, varied groups of researchers dealing with search, optimization, and learning (SOL) met SE researchers, all of them looking for a quantified manner of modeling and solving problems in the software field. This paper will discuss on the construction, assessment, and exploitation tasks that help in making software programs a scientific object, subject to automatic study and control. We also want to show with several case studies how the quantification of software features and the automatic search for bugs can improve the software quality process, which eases compliance to ISO/IEEE standards. In short, we want to build intelligent automatic tools that will upgrade the quality of software products and services. Since we approach this new field as a cross-fertilization between two research domains, we then need to talk not only on metaheuristics for SE (well known by now), but also on SE for metaheuristics (not so well known nowadays). In summary, we will discuss here with three time horizons in mind: the old times [before the term search-based SE (SBSE) was used for this], the recent years on SBSE, and the many avenues for future research/development. A new body of knowledge in SOL and SE exists internationally, which is resulting in a new class of researchers able of building intelligent techniques for the benefit of software, that is, of modern societies.

Every year, the availability of public IPv4 addresses is running low. However, the IETF (Internet Engineering Task Force) has set a new addressing standard called IPv6 (Internet Protocol version 6). IPv6 implementations can not be immediately performed on all end-to-end lines, a transition phase is required, one of which is the GRE tunneling method. IPv6 has some differences with IPv4, then in line with the presence of IPv6 will required the protocol that compatible with IPv6, among which is the routing protocol. Some dynamic routing protocols are created to support and can run on IPv6 such as RIPng and OSPFv3. Aim of this study is examines OSPFv3 routing protocols and RIPng routing protocols in terms of Quality of Service (QoS). The test is done by using seven routers with three scenarios in each routing protocol, ie scenario with best path active condition, when the network changes in other words best path down, and the scenario with best path condition has changed and the network has returned to normal. Testing is done by testing QoS parameters (delay, packet loss, and throughput) when the client computer downloads files with the .iso extension from the server. Downloaded files have different sizes, from 100 Mega Byte to 1 Giga Byte. From the results obtained that OSPFv3 provides better QoS (delay, packet loss, and throughput) than RIPng on integrated IPv6 network using GRE tunnel and can be a reference when going to transition from IPv4 to IPv6 using GRE Tunnel.
