What computer field should I major in?

What is the scope of computer networking in India? What different jobs are available in the networking field? What companies in India are recruiting people with networking skills?

• Please give the details of the kind of work  that has to be done in computer networking field.Throw some light on this field.

• Answer:

  There is scope for Networking in india , but it has not yet grown up. For networking , its the service providers which hire most of the professionals for configuring/maintaining/designing their network. We have big service providers like Airtel/Reliance but they don't really hire network professions as the US Service providers hire becuse in india we really dont care about SLA (Service level agreement) . In case you want to start your career from networking, you need to know what do you want to do first : a) If you want to design new protocols or work on existing protocols , you should focus on programming aspects and now with the advent of Openflow & SDN , things are much easier. Get some courses from coursera on SDN and start programming such stuff. https://www.coursera.org/instructor/feamster b) If you want to work on designing of network , then you should go for CCNA and have sound knowledge of some technology , be it routing & switching or voice protocols or video protocols and get into companies like Cisco Customer Advocacy or Cisco Technical Assistant division or Juniper or netapp or emc2. c) If you want to do programming on network interfaces like SDN or network operating systems , then focus more on C programming , Java internals ,operating system and data communication. Lot of companies are for this area like Tejas , Cisco , juniper, alcatel Lucent, netapp, arista networks. d) If you are looking for H/W programming on network devices, then you should focus on Verilog , Matlab and stuff where companies like Tejas, Broadcom , intel hire people for. If you are just looking for Networking knowledge and latter on going to decide , you can read about the below read OSPF,IGRP and EIGRP why OSPF is widely used Why EIGRP is having fast convergence What is big-endian and little-endian architecture. What r system calls how system call and kernel works, userspace and kernel space what is monolthic kernel and macrokernel what is Web 2.0 and Web3.0 and now even 4.0 ? Openflow , SDN and network Virtualization. Email Protocols..who packet is encapsulated and decaps during an email is sent from me to you. what is socket? socket primitives? C in Unixs----by vijay mukhi in library first two chapter read then and make all the programs so as to clear the doubts in fork , exec read and other system calls C by dennis ritchie whole book is neccessary ..go through it deeply read data structures : link list (loop avoidance using two pointers one pointing to next and other pointing to next->next..traverse both pointers if these pointers meet then there is a loop else if they meet at null then no loop) Mutex and semaphore . stacks(in context switching) queues(priority queue..used in network traffic and process scheduling) trees-----most imp of all D.S's ......Shortest path first, Avil tree, and other algo's what is http?why stateless protocol TCP header and IPv4 header Fields IPv6 header and some internals . OSI model ...study protocols on each layer atleast on one or two protocols each layer. you should know how many layers of tcp and osi model . Devices at various layers Difference between hub, switch, router, bridge , gateway . what is tcp and ip protocol Sliding window protocol Difference in routing and routed protocols Overview of few routing protocols : rip , ripv2, ospf, eigrp, igrp what is http and https flow control in tcp Layer 3 protocols like RIP, OSPF, BGP, IP Unicasting, IP Multicast –PIM-SM, PIM-DM, DVMRP,IPv6 MPLS, FIPS Management Plane- SNMP, Web server Knowledge of Control Plane Protocols (OSPF / ISIS) Telecom technologies - SONET, SDH, DWDM, Carrier Ethernet (PBB/PBT) or MPLS
