- 3. Outlines Introduction to Organization Profile. UTL Services in Jharkhand. Basic of Data Communication Networks. Communication Networks Components. IP Addressing. Applications of UTL Services. Conclusion and References. Kalyan Acharjya
- 4. UTL Profile United Telecoms e-Services Pvt. Ltd., Ranchi, Jharkhand is a UTL group of companies, looking after the CSC Project in Jharkhand. United Telecoms Limited (UTL) Group is a Bangalore based, ICT Solutions Company with wide experience in setting up telecom networks, e-governance. Powering Ideas into Communication Kalyan Acharjya
- 5. UTL Profile… UTL Group of Companies are engaged in Design, Manufacturing, Software Development in the areas of Telecommunications. For example networking, systems integration, software solutions, PCB manufacturing, microelectronics design etc. Kalyan Acharjya
- 6. UTL Services Govt. Services for Citizens • Adhar Card, Apna CSE, PAN Card, e-district • E-nagarik Utility Services • Know the bill, Pay world Services. • Bank Branch Locator, Banking Services • For all public services banks. Kalyan Acharjya
- 7. Basics of Communication Network Network is a collection of computers, printer, routers and switches and other communication devices that are able to communicate to each other through some transmission media. Other way network is physical connection between computing devices established using cable media or wireless media. Kalyan Acharjya
- 8. Structure of Communication Networks Kalyan Acharjya
- 9. Some Communication Networks Component • Router is a device which connect different networks. • A router which forward data packets between computer network, connecting an overlay internetwork. • Three Modes- • User mode. • Privileged mode. • Global configuration mode. Kalyan Acharjya
- 10. Modes of Router User mode: • Only some basic monitoring. • Limited show commands ping ,trace etc • Router> Privileged Mode: • Monitoring and some troubleshooting. • All show commands, ping trace, copy and erase • Router# Global Configuration Mode: • To make any change that affect the router like hostname, routing configuration. • Router (config)# Kalyan Acharjya
- 11. Basic Commands User Mode: • Router> • Router>enable Global Configuration Mode: •Router#Configure Terminal •Router(config)#Hostname R-1 •R-1(config)#Show IP route •R-1(config)enable password<password> •R-1(config)enable secret <password> Privileged Mode: •Router#Show running-config •Router#Show start-config •Router#Show flash •Router#Show version •Router#Show ip interface brief Kalyan Acharjya
- 12. • A Network Switch is a small hardware device that joins multiple computers together within one LAN. • It is networking device that connect devices together on computer network by using packet switching to receive, process and forward data on destination devices. Other Communication Networks Component: Switch Kalyan Acharjya
- 13. Idea about IPAddress • Internet Protocol address is numerical label assigned to each device participating in a computer network that uses the internet protocol for communication . • An IP address has 32 bits divided into four octets. • To make the address easier to read, people use decimal numbers to represent the binary digits e.g. 192.168.1.1 • IP Address Classes- • Class A • Class B • Class C • Class D Kalyan Acharjya
- 14. • Class A: Reserved for governments and large corporations throughout the world and supports 16,777,214 hosts. • Class B: Addresses are assigned to large and medium sized companies and supports 65,534 hosts. • Class C: Addresses are assigned to groups that do not meet the qualifications to obtain Class A or B addresses and supports 254 hosts • Class D: Addresses (also known as multicast addresses) are reserved for multicasting. Multicasting is the sending of a stream of data (usually audio and video) to multiple computers simultaneously IPAddress Classes Kalyan Acharjya
- 15. IPAddressing The network address is the first address. The network address defines the network to the rest of the Internet. • A mask is a 32-bit binary number and the mask is ANDed with IP address to get the block address (Network address) • Mask And IP address = Block Address Kalyan Acharjya
- 16. IP Addressing: Basic Idea of Sub netting Split the host number portion of an IP address into a Subnet number and a (smaller) Host number. Result is a 3-layer hierarchy Subnets can be freely assigned within the organization Internally, subnets are treated as separate networks Subnet structure is not visible outside the organization network prefix host number subnet numbernetwork prefix host number extended network prefix Kalyan Acharjya
- 17. IP backbone routers have one routing table entry for each network address. With sub netting, a backbone router only needs to know one entry for each network This is acceptable for Class A and Class B networks 27 = 128 Class A networks 214 = 16,384 Class B networks But this is not acceptable for Class C networks 221 = 2,097,152 Class C networks In past year the size of the routing tables started to outgrow the capacity of routers The Class-based assignment of IP addresses had to be discarded. IP Addressing: Classless Addressing Kalyan Acharjya
- 18. IP Addressing : CIDR - Classless Interdomain Routing Goals: Restructure IP address assignments to increase efficiency Hierarchical routing aggregation to minimize route table entries. Key Concept:The length of the network id (prefix) in the IP addresses is kept arbitrary. Routers advertise the IP address and the length of the prefix. CIDR notation of a network address: 192.0.2.0/15 "15" says that the first 15 bits are the network part of the address (and 14 bits are available for specific host addresses) The network part is called the prefix. Kalyan Acharjya
- 19. Applications of UTL Services Jharkhand State Wide Area Network(JHARNET)-The Network integration with entire Jharkhand. Pragya Kendra. Jail Sakshatkar. Online grievance redressal through e-Samvaad. Online Land records. The State Blindness Control Society has started to use the CSC network in Eye Screening (School Children) Various Banks, Dept. of Posts etc…. Kalyan Acharjya
- 20. Conclusions: During the internship, I have practically gained the knowledge of communication networks. Practically felt the experienced that how data communication networks devices (e.g. router, switches etc) are configured and this was enhanced my industrial knowledge in this field. There was another interesting part to do the work in teamwork and also understood that working way in industry. Data Communication networks is a vast area, though I have covered the IP addressing part during my summer internship. This internship was most amazing that I have ever experienced and I would like to visit UTL again in near future to learn the other system and software skill in computer networks domain.
