International Terrestrial Cable in Bangladesh

world(pre n unrivaledinal) Terrestrial seam in BangladeshChapter 1 Introduction1.1 Introduction of the reputeThe mesh has become an essential part of human life as it is the main mode of communicating now a days. Internet is the middleman up computer network where billions of devices ar connected through the backbone of ocular networking technologies in modern days. My interest was to observe the rapid using of this communication mode and for this I have studied the opthalmic transmission and networking systems and polar protocols by working as an intern in the no(prenominal) department of 1 Asia alinement confabulation Ltd. Finally I have make a report of whatever I have learnt throughout my 3 months eagle-eyed internship program.1.2 Reason for selecting the specific industryTelecommunication is growing with the vast engross of internet in Bangladesh. The introduction of ocular role transmission both(prenominal) in submarine and terrestrial over satellite communic ation made it easy to spread the global connectivity throughout the major cities in Bangladesh. 1 Asia Alliance discourse 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 optic transmission technology. To better understand the ocular transmission system and the IP network system it was the best extract to join as an intern in a association same(p) 1 Asia Alliance parley Ltd.1.3 Purpose of the InternshipTo fulfill the requirements for the degree of the bachelor-at-arms 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 look at done.1.4 Methods of Collecting selective trainingThe selective information for making this report was collected in many wa ys. indigenous info, as well as secondary selective information for end the task of report writing about this internship were employmentd. Some of the methods which argon 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 communicating Ltd. leaflet1 Asia Alliance Communication Ltd. websitesSeveral articles on the internet link with the field of weigh query reports of several(prenominal) authors related with the field of fieldChapter 2 terra firmas2.1 Background of ITC and IIG in Bangladesh planetary Terrestrial Cable (ITC) instrumentIn 2006 the internet of Bangladesh has been connected to the world by a integrity submarine cable, Sea-Me-We 4 (SMW4). SMW4 is 18,800 kilometer- vast ocular- grapheme system and its landing st ation of Bangladesh is at follows Bazar. Since SMW4s activation, national Internet outages have struck Bangladesh in regular basis. When any portion of this opthalmic fiber system is damaged, it germinates gigantic time for tutelage and frankincense virtually 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 construction 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 be after 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 Commissi on (BTRC) to take substitute measures. In 2012, the BTRC issued licenses to six companies to connect to India via the International Terrestrial Cable (ITC).The six International Terrestrial Cable (ITC) operators are1Asia Alliance Communication Ltd.,Novocom LimitedBD Link Communication Ltd.,Mango Teleservices Ltd.,Summit Communications Ltd., andemailprotected Limited.This inception of an operational terrestrial connection to India to serve as an alternative to SMW4 is a great achievement for Bangladeshs telecommunication sphere of influence. Currently these six ITC operators are connected to Tata Communications and Bharti Airtel via Benapole TCLS.International Internet accession (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 so number of IIG operators grow in this clownish. Cur rently there are 36 licensed IIG operators in Bangladesh. Few Major International Internet Gateway (IIG) operators are1Asia Alliance Communication Ltd.Aamra CompaniesAbir TelecommunicationApple CommunicationBangla send for LtdbdHUBBD Link CommunicationBSCCLBTCLCybergateDelta InfocomEarth TelecommunicationEquitel CommunicationsFiber home(a)Global Fair CommunicationsGreenland TechnologiesIntraglobe CommunicationsLevel3 CarrierMango TeleservicesMaxNet OnlineNovoCom bright Communications LimitedREGO CommunicationsIIGs in Bangladesh serve as a gateway for routing International incoming and outgoing Internet establish data traffic additionally working as a national internet exchange (NIX) for exchanging national internet- found data traffic.Most of the gateways are connected with rurals sole submarine cable SMW4 as their main link and with the satellite earth station/VSAT as back up until a nonher(prenominal) submarine cable SMW5 is available. When ITC operators in Bangladesh were int roduced these IIG companies started using ITC services as an alternative to SMW4. BTRC has made a rule that all ISPs in Bangladesh shall be connected to global internet through these IIGs.IIG operators mainly provide their services to the ISPs, carriers and vast corporations of the country. They use extensive local and international 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 stripped-down number of hops. These operators give their customers the choice to subscribe the bandwidth based on the terminal 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 formed between Alliance Holdings Limited, Bangladesh and 1Asia Communication (BD) Ltd. It is a sister concern of ca pital of Singapore based 1Asia Communication Pte. Ltd. The company was formed by a group of NRBs with over 20 age experience in the telecommunications business.The company carries the licenses from BTRC to provide ITC and IIG services to its clients in Bangladesh. 1AACL is in addition 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 eminenter(prenominal) internet penetration.The ITC project of 1AACL brings a much undeniable 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 serviceCl ient 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 foundation2012 to 20131AACL head quarter setupBenapole POP setupITC backhaul setup1Asia Alliance own WDM meshworkSecondary ITC interlocking SetupTertiary ITC Network SetupInterconnection Equinix, SingaporeInterconnection TATA, Chennai MumbaiInterconnection Airtel, ChennaiInterconnection TIS, Singapore2013 to 2014Chittagong fling off SetupPop at ColoAsia, DhakaLondon Pop SetupPeering with Google, Facebook, MicrosoftInterconnection Epsilon GH, LondonInterconnection Level3 CogentInterconnection Equinix-IX SG-IX2014 to indicat eNew York, USA Pop SetupDepartmentsAdministrationAccountsMarketinggross revenueLogisticsHRTechnical transmission, IP Core, Service Deli rattling , NOCStrengthITC Backhaul Systems (Dhaka- Benapole)Primary ITC Network 1Asia Alliances Own System WDM network with 8 Lamda capacitySecondary ITC Network emailprotected /SwappingTertiary ITC Network ITC Consortium/metropolis CellNumber Of ITC Operators in Connection 06Cisco 12000 Series Flagship Routers as Core Aggregation EquipmentFull Routing TABLE Implementation Auto cast OverRouting Through ITC with different upstream carrierSwitch inhabit 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 query papersResearch Paper 1 title of respect soliton Transmission in Fiber opthalmics for Long Distance CommunicationAuthors Mehul G.Patel (1), S.
