International Terrestrial Cable in Bangladesh

Inter depicted object Terrestrial Cable in BangladeshChapter 1 Introduction1.1 Introduction of the reportThe meshwork has turn an essential part of human life as it is the main mode of communication now a days. Internet is the interconnected com vomit uper network where billions of devices are connected through the backbone of optical networking technologies in modern days. My interest was to observe the rapid development of this communication mode and for this I name canvass the optical transmission and networking strategys and different protocols by working as an intern in the NOC department of 1 Asia bail bond confabulation Ltd. Finally I have baffle a report of whatever I have learnt throughout my 3 months coherent internship program.1.2 Reason for selecting the specific industrytelecommunication is growing with the commodious use of internet in Bangladesh. The introduction of optical eccentric transmission both in submarine and terrestrial all over satellite commun ication made it easy to spread the global connectivity throughout the major cities in Bangladesh. 1 Asia Alliance parley Ltd. is one out of six companies which has the ITC license. Thus it serves as a domestic internet upstream for all the major ISP, IIG and IGW companies in Bangladesh using its terrestrial optical transmission technology. To better understand the optical transmission system and the IP network system it was the best choice to join as an intern in a company like 1 Asia Alliance intercourse Ltd.1.3 Purpose of the InternshipTo fulfill the requirements for the degree of the Bachelor of Electronics and Telecommunication Engineering.To see the practical implementation of what was studied during the university program.To learn how a telecom company operates its technical functions.To make recommendations on the basis of the study done.1.4 Methods of Collecting DataThe data for making this report was collected in many ways. pristine data, as well as secondary data for co mplementary the task of report writing about this internship were apply. Some of the methods which are used are discussed below.Use of Primary DataPrimary Data which were used for completing the report are as followsSelf-observationDiscussions with the officersInformal interview from the customersUse of Secondary DataSecondary Data which were used for completing the report are as follows1 Asia Alliance Communication Ltd. brochure1 Asia Alliance Communication Ltd. websitesSeveral articles on the internet related with the region of study explore reports of several authors related with the field of studyChapter 2 telescopes2.1 Background of ITC and IIG in BangladeshInternational Terrestrial Cable (ITC) meansIn 2006 the internet of Bangladesh has been connected to the world by a single submarine cable, Sea-Me-We 4 (SMW4). SMW4 is 18,800 kilometer- presbyopic optical-fiber system and its landing station of Bangladesh is at Coxs Bazar. Since SMW4s activation, national Internet outages have struck Bangladesh in regular basis. When any portion of this optical fiber system is damaged, it takes huge time for maintenance and thus around all internet bandwidth of Bangladesh disappears,pushing local internet providers to retreat to slow and expensive satellite services or to simply wait for restoration.A 20,000 km long secondary optical fiber system SMW5 is under braid and the landing port in Bangladesh will be at Mongla The SMW5 consortium signed the construction and maintenance agreement on March 7, 2014. But the complexation will take long time. In the meantime, major disruptions of Bangladeshs Internet service continue to occur.The plotted maintenances and failures in SMW4 system make all understood that how susceptible Bangladeshs internet connectivity really is. These events thus encourage the Bangladesh Telecommunications Regulatory Commission (BTRC) to take selection measures. In 2012, the BTRC issued licenses to six companies to connect to India via the Int ernational Terrestrial Cable (ITC).The six International Terrestrial Cable (ITC) operators are1Asia Alliance Communication Ltd.,Novocom LimitedBD cerebrate Communication Ltd.,Mango Teleservices Ltd.,Summit Communications Ltd., andemailprotected Limited.This inauguration of an operational terrestrial connection to India to serve as an alternative to SMW4 is a great achievement for Bangladeshs telecommunication sector. Currently these six ITC operators are connected to Tata Communications and Bharti Airtel via Benapole TCLS.International Internet Gateway (IIG) operatorThe telecom sector in Bangladesh is rapidly exposing. Bangladesh Telecommunication Regulatory Commission (BTRC) is the regulatory authority for this sector. In 2007 BTRC offer the license forInternational Internet Gateway (IIG) and from then number of IIG operators grow in this country. Currently in that location are 36 licensed IIG operators in Bangladesh. Few Major International Internet Gateway (IIG) operators are1A sia Alliance Communication Ltd.Aamra CompaniesAbir TelecommunicationApple CommunicationBangla Phone LtdbdHUBBD Link CommunicationBSCCLBTCLCybergateDelta InfocomEarth TelecommunicationEquitel CommunicationsFiber HomeGlobal Fair CommunicationsGreenland TechnologiesIntraglobe CommunicationsLevel3 CarrierMango TeleservicesMaxNet OnlineNovoComradiant Communications LimitedREGO CommunicationsIIGs in Bangladesh serve as a gateway for routing International incoming and outgoing Internet based data dealings additionally working as a national internet exchange (NIX) for exchanging national internet-based data traffic.Most of the gateways are connected with countrys fix submarine cable SMW4 as their main link and with the satellite earth station/VSAT as back up until another submarine cable SMW5 is available. When ITC operators in Bangladesh were introduced these IIG companies started using ITC services as an alternative to SMW4. BTRC has made a rule that all ISPs in Bangladesh shall be conn ected to global internet through these IIGs.IIG operators primarily provide their services to the ISPs, mail carriers and large corporations of the country. They use extensive local and internationalistic internet peering and transit. Even IIGs are interconnected with national IX (Internet Exchange) BDIX and several international IX thus their customers can access all global internet routes through the minimum number of hops. These operators give their customers the choice to subscribe the bandwidth based on the destination of their traffic. Their goal is to reduce network traffic congestion and maintain shorter latency.2.2 Background of the companyAbout the company1Asia Alliance Communication Limited (1AACL) is a joint venture company make between Alliance Holdings Limited, Bangladesh and 1Asia Communication (BD) Ltd. It is a sister concern of Singapore based 1Asia Communication Pte. Ltd. The company was formed by a group of NRBs with over 20 years experience in the telecommunic ations business.The company carries the licenses from BTRC to provide ITC and IIG services to its clients in Bangladesh. 1AACL is also the first ITC operator in Bangladesh. Since its birth, 1AACL has established enormous footprints in the ICT sector of the country. It is running parallel with the countrys drive towards digitalization and higher internet penetration.The ITC project of 1AACL brings a much required backup for to the countrys lone submarine cable SMW4. The company offers its services to several ISPs, IGWs, IIGs, and corporate clients across the country.LicensesIIG License awarded on 12/04/2012, commercially started on 01/10/2012ITC License awarded on 05/01/2012, commercially started on 12/12/2012ServicesIPLC/MPLSIP TransitSatellite BW serviceManaged data network serviceVPN serviceCo-location serviceClient typesIIGsISPsIGWsEnterprise customersInternational PoPs (Point of Presence)ChennaiMumbaiEquinix Building, SingaporeEpsilon Global Hub, London60 Hudson Street, NYLocal PoPsHQ-Alliance Building, capital of BangladeshColoasia-Borak tower, DhakaChittagong-Akhtaruzzaman Center, AgrabadBenapole-Chowdhury Super Market, Zero Point, Check Post, BenapoleTechnology PartnersTata Communication LtdBharti AirtelTISChunghwaEquinix-IXSG-IXLevel3CogentGoogleTimeline of Infrastructure2012 to 20131AACL head quarter setupBenapole POP setupITC backhaul setup1Asia Alliance own WDM NetworkSecondary ITC Network SetupTertiary ITC Network SetupInterconnection Equinix, SingaporeInterconnection TATA, Chennai MumbaiInterconnection Airtel, ChennaiInterconnection TIS, Singapore2013 to 2014Chittagong gobble up SetupPop at ColoAsia, DhakaLondon Pop SetupPeering with Google, Facebook, MicrosoftInterconnection Epsilon GH, LondonInterconnection Level3 CogentInterconnection Equinix-IX SG-IX2014 to PresentNew York, the States Pop SetupDepartmentsAdministrationAccountsMarketingSalesLogisticsHRTechnical transmitting, IP Core, Service Delivery , NOCStrengthITC Backhaul Systems (Dha ka- Benapole)Primary ITC Network 1Asia Alliances Own System WDM network with 8 Lamda capacitySecondary ITC Network emailprotected /SwappingTertiary ITC Network ITC Consortium/City CellNumber Of ITC Operators in connective 06Cisco 12000 Series Flagship Routers as Core Aggregation EquipmentFull Routing TABLE Implementation Auto Switch OverRouting Through ITC with different upstream carrierSwitch Room Level Redundancy in National SegmentInternational PoPs at Chennai, Mumbai, Singapore, London, New YorkNative IPv6 Peering (Upstreams Major Players)Direct Peering, Impressive RTD2.3 Background study on research papersResearch Paper 1Title solitary wave Transmission in Fiber Optics for Long Distance CommunicationAuthors Mehul G.Patel (1), S.
