Research Paper: CalREN Systems

Research writing CalREN SystemsIntroductionThe Corporation for Education engagement Initiatives in atomic number 20 (CENIC) date that they the state of calcium mickle achieve greater heights if they disc whole oer it a better and more than improved internet. On April 9, CENIC announced that they had talked with the applied science giants and be working on the same project and those partners are spill to provide all in all the hardware and communication engine room to create a more robust interlocking for California known as CalREN-2 which would be high performance internet for the California. The high- recreate mesh topologying hardware such as routing and switching equipment will be provided by Cisco System, Pacific tam-tam Communications.California Research and Education Network (CalREN) is amongst the most powerful technology tool California has in its sleeves. The communicate infrastructure is a multitiered net profit with around 3,800 miles of fiber optic con necting over ten thousand genteelnessal and research institutes and universities similar California State, Stanford, USC and community colleges to 58 counties of California. The CalREN brass is all told owned and monitored by the Corporation for Education Network Initiatives in California (CENIC), a non-profit organization which was established in 1996 by the mixed education and research communities from California to create a very(prenominal) high bandwidth and economic declaration to intercommunicateing that would meet the needs of the faculty and all savants which belong to these variant schools and universities.GoalsCalREN is completely monitored by the CENIC now and has new goals to achieve high tone of voice painting conferencing to the classes to let students receive high quality education in real- period at all levels even if the faculty is not before long make up in the city, state or nation. This would similarly connect m some(prenominal) scientists around the globe to this existing high bandwidth earnings. With CalREN, various artists could take blend in stream classes of the production house from institution like San Francisco Opera from both part of the world. The San Francisco would create an online ikon classes to students through with(predicate)out the world and would piece of ground these libraries so that all the musicians could learn music via special software or any streaming media. Recently, Los Angeles has also been geted to CalREN system in 2016.Backbone The CalREN acantha provides various capabilities to the network as followsCalREN-DCThe Digital California is presented for everyday applications like video conferencing, emails, web browsing etc with a bandwidth of 10 Gbps to the students and faculty.CalREN-HPRThe High-Performance Research network which is employ for applications with high info needs. This is a high-end network with a speed of 40Gbps.CalREN-XDThe eXperimental/Developmental network is a get net work to new(prenominal) table servings for network research in universities like University of Southern California, advance Computing Research at Caltech etc. This is to have a pore perspective on research and innovation on the network. Backbone chain of mountains from, http//cenic.org/network/network-mapsThe Central Valley Next Generation Broadband radix Project (CVNGBIP)The Central Valley Next Generation Broadband nucleotide Project (CVNGBIP) was implemented to provide internet connectivity in 18 counties. except 8% of the nations agricultural output is produced by the central valley. This kind of a strong and robust infrastructure network was implemented because central valley was still not completely connected to the internet.This was possible because of a great deal in mind next generation connectivity where people living in those counties throw out learn things in a different way departure the traditional way of learning behind where people used to consume eac h other for tips and methods. This is when two organizations CENIC and Central Valley Independent Network (CVIN) came together forming a inwardnesst venture making this like a dream come true and provide a better prospective to the people. The expediency also aims to keep the cost of the internet service as low as possible to assistant the schools, universities hospitals etc. to take as much as profit they can.The project was funded by NTIA (70%), California worldly concern Utilities Commission (CPUC)s CAS Fund (10%) and the rest form other parties and the total get along is to be estimated at around 66 million involving 1,371 miles of cabling and connecting businesses together.California depository library Initiatives at that place are various enterprises by the California libraries. Video conferencing, emailing, and human beings research to schools and colleges are enhancing the learning possibilities at high level. Many benefits and innovative ideas are initiated at the Public libraries making them abundant possibilities to achieve more in the coming future. Therefore, merging these libraries with CalREN would be an addition to the feature and service provided in digital age where everything and everyone is connected.Pacific Research Platform (PRP) initiativePacific Research Platform (PRP) is an initiative carried forward by UC San Diego and Berkeley which would help the college network for data access to be much faster than it is instantly within a few years. There is also a 5 million dollars funding for the initiative from the National Science Foundation (NSF). this would help the PRP with this grant.Quality of Service (QoS)Quality of Service (QoS) is the service provided by the network service provider that would affect the overall availableness of the computer duration performing certain task related to the internet connectivity. It is generally used to measure overall network performance over few characteristics like bandwidth, transmission delay etc. CalREN is a very high bandwidth network that provides is vital services to various research institutes throughout California hence, making quality of service a very important aspect to CalREN system. deoxycytidine monophosphate Gigabit Ethernet connectionsTo achieve superfast speed for faster data travel, we need a higher capacity bandwidth. This is all possible by implementing and installing 100 Gigabit Ethernet connections that support lightning fast transmission over fibers or over the air. This is achieved with framerate of 100 gigabits per befriend bandwidth providing services to laboratories and research centers where in that location are supercomputers that can use this ample capacity bandwidth along other big facilities. A supercomputer in San Diego is use this speed and is connected to CalREN system.Network trading operations Center (NOC)Network Operations Center is a building or a place where all the network connections are monitored, managed and if possib le or need arises are also troubleshoot so that to avoid any possible chances of network failure or unavailability of the service. CalREN uses a multitiered network as we discussed earlier that allows access to many another(prenominal) universities and research centers throughout California. This is where NOC would play important role in the system to manage and troubleshoot the network in any such cases.Applications for CalRENOn troop 2006, at the CENIC workshop, iGrid showcased and important application of CalREN to the people. It was an data-based real-time broadcast of very high quality 4K video that was very much improved over our conventional televisions. They were also awarded networking innovation award.There was an issue with the video over the internet protocol on the CalREN-DC network. To trouble shoot the riddle they fitted the new codec for the video broadcast throughout the CalREN system. Since the new codec was transmitted through packets, high quality of service was a concern which can be overlooked if we use the CalREN systems high speed network.K20 VideoCalREN is supporting this project by providing high speed internet connections. K20 video is an adaptation of video conferencing technology throughout the state with the collaboration of all K12, University of California and California State University sites. This is achieved by improving the distance learning scheme by providing high quality video services to all the students and faculties.End-sites connected to CalREN-DC networkThere are 34 end sites to the CalREN-DC network. Everyone are victimization optic fiber for their access technology. The capacity provided to the end-sites is more than sufficient as we can see that some of the sites are underutilized and need proper resource precaution as most of the resource are wasted.End-sites connected to CVNGBIP networkThere are many things that are carried forward in the fields of health care, business and residential with more than 6300 0 access lines. they are also using optical fibers for their access technology.SLA performance guarantees of CALRENThe SLA performance guarantees are as of November 2006.Implementing ticketing system to the educational institution with 99% availability. Various means of deployment would be appoint and operations to be performed to avoid outages. The jitter form central point to Los Angles for round-trip time should not be over 80 ms in 5 minutes. SLAs will be forced in all regions of network deployment such as fibers, routers etc. and use third party equipment to solve the problem.The problem can also be rectified by mailing to emailprotected to pack appropriate actions necessary.All the performance guarantees seem reasonable as there is a definite time to resolve any issue and polish the problem using the ticketing system that is very efficient everywhere in communications business.Hierarchy in CalRENCalREN is a multitiered network with 3 tiers. CalREN-XD with experimental or de velopmental abilities, CalREN-HPR for big applications and CalREN-DC with 10gbps bandwidth for research institutes and video conferencing uses. The CalREN-DC would consist of 3 level hierarchy network as a final design. unrivalled will be hub sites following with level two as nodes sites and all these node sites connected to CalREN infrastructure where all the schools, colleges and universities will be connected to each other for informationBackbone LocationsThe backbone locations for the CalREN are Corning, Sacramento, San Francisco, Oakland, Fergus, Sunnyvale, Fresno, Soledad, Bakersfield, San Luis Obispo, Riverside, Los Angeles, Tustin, and San Diego. to the highest degree of the sites are reasonable but Tustin could be dropped as it can share resources from either of the two Los Angeles or Riverside. In future, maybe we can add San Jose or Palo Alto as it is booming in I.T infrastructure and the data availability would be much more and easy to troubleshoot.CSUEB to CalRENFollow ing are the links that connect CSU East Bay to CalRENLinkSpeed medium Utilizationeb-csu 10G DF to svl-agg4 Te0/7/0/4.212 CLR 637810 Gbps9.8%eb-csu 10G DF to oak-agg4 Te0/4/0/7.208 CLR-636610 Gbps10.3%To take full advantage of the bandwidth we could start features like online classes where a student could also attend classes if he/she is sick and cannot be physically present at the lectures or this could be also helpful to the students who need accessibility services.Also, keeping the bandwidth use in mind, we could also upload our video presentations over the network that could be asked to be rated or grades accordingly by our classmates. analyse CalREN2 with SoXSouthern Crossroads (SoX) is an organization that provides high capacity internet service with global connectivity in Atlanta. It serves with internet2 to provide international research access.by the help of its supporters, SoX can implement a very low cost internet service in the whole Atlanta area. Comparing it to CalREN, SoX supports k-12 education as easy as federal agencies in the united states. Similarly, CalREN is also powering research in various field in networking and development for the institutes.ConclusionThe CalREN system is an nice design and the robust characteristic makes it a strong and better solution to form of higher level learning with technology.few Strengths of CalREN is that the infrastructure is think on various educational institutes and research facilities. Helping public libraries join CalREN is a brilliant step towards achieving that goals per the situation.CalREN also has few weaknesses amongst itself. We have seen that the backbone supports the CalREN which is a good thing but most of the links are underutilized which can be improved drastically over a period. Few of the resources could also be shared among sites which are close to each other saving expensive resource.Referenceshttp//www.cvngbip.orghttp//cenic.org/network/library-initiativehttp//cenic.org/files/public ations/2011-13CENICAR.pdfhttp//en.wikipedia.org/wiki/100_Gigabit_Ethernethttps//en.wikipedia.org/wiki/Network_operations_centerhttp//www.sunnycv.com/steve/local/pacific/art980408.htmlhttp//cenic.org/network/network-mapshttp//cenic.org/network/service-level-expectationshttp//prp.ucsd.edu/http//www.sox.net/about-us/https//intermapper.engineering.cenic.org/CENIC%20-%20DC%20Backbone%20Overview/document/_/full_screen.html
