Flipkart – A new option for Online shopping

Most of you would have seen a television commercial where a mouse keeps running inside a wheel. So you guys must be familiar with the name FLIPKART if you have watched the advert. If not, let me tell you what Flipkart is.

Flipkart is an Indian electronic commerce company headquartered in Bangalore, India. It is the largest online bookstore in India.Flipkart was established in October 2007 by Sachin Bansal and Binny Bansal. Both are alumni of Indian Institute of Technology Delhi and worked before quitting and founding their own company. Initially they used word of mouth marketing and social networking websites to popularise their company. Flipkart broke even in March 2008 and claims to have had at least 100% growth every quarter since its founding. The store started with selling books and in 2010 branched out to selling CDs, DVDs, mobile phones and other electronic gadgets. During financial year 2009-10, it reported a sales of Indian Rupee ₹ 20 Crores (200 million). Initially funded by the Bansals themselves, Flipkart has since then raised two rounds of funding from venture capital funds Accel India (2009) and Tiger Global Management (2010). The company has 1000 employees.

Why IPv6 was born

The network layer protocol in the TCP/IP protocol suite is currently IPv4. IPv4 provides the host-to-host communication between systems in the Internet. Although IPv4 is well designed, data communication has evolved since the inception of IPv4 in the 70s. IPv4 has some deficiencies that make it unsuitable for the fast growing Internet, including the following:

  • Despite all short term solutions,such as subnetting, classless addressing, and NAT, address depletion is still a long term problem in Internet
  • The Internet must accommodate real time audio and video transmission. This type of transmission requires minimum delay strategies & reservation of resources not provided by IPv4 design.
  • The Internet must accommodate encryption & authentication of data for some applications. No encryption or authentication is provided by IPv4.

To overcome these, IPv6 also known as IPng (Internet Protocol next generation) was proposed and is now a standard.In IPv6, the Internet protocol was extensively modified to accommodate the unforeseen growth of the Internet. The format and the length of the IP addresses were changed along with the packet format. Related protocols such as ICMP were also modified. Other protocols in the network layer, such as ARP, RARP, IGMP were either deleted or included in ICMPv6 protocol. Routing protocols such as RIP and OSPF were slightly modified to accommodate these changes.

The adoption of IPv6 has been slow. The reason is that the original reason for its development, depletion of IPv4 addresses, has been slowed down because of 3 short term remedies

  • Classless addressing
  • Use of DCHP for dynamic address allocation
  • NAT

However, the fast spreading use of Internet and new services such as mobile IP, IP telephony, and IP-capable mobile telephony, may require the total replacement of IPv4 by IPv6.

Advantages os IPv6

Larger address space-An IPv6 address is 128 bit long. Compared with the 32 bit long IPv4 address, this is huge increase in address space.

Better Header format-IPv6 uses a new header format in which options are separated from the base header and inserted when needed, between the base header and the upper layer data. This simplifies and speeds up the routing process because most of the options do not need to be checked by routers.

New Options-IPv6 has new options to allow for additional functionalities.

Allowance for extension-IPv6 is designed to allow the extension of protocol if required by new technologies or applications.

Support for resource allocation-In IPv6, the type-of-service field has been removed, but mechanism called Flow label has been added to enable the source to request special handling of packet. This mechanism can be used to support traffic such as real-time audio and video.

Support for more security-The encryption and authentication options in IPv6 provide confidentiality and integrity of the packet.

To IT or Not to IT

This post is for all the people who want to make a career in IT industry.

Well, if you guys think IT industry is an easy source of income, then just remove the thought from your mind because it is the most stressing sector.

IT industry has one simple motto-PERFORM or PERISH.

You don’t work extra time to earn more money but you do so to keep your job intact. The competition is so intense and cut throat that performance matters a lot. Hence there is an inherent pressure on every employee to perform since there are many others standing in the queue to take up the same position.

So a lot of stress is generated because of this pressure of performance and the insecurity of job.

It’s like a mirage that a thirsty traveler sees in the desert. It calls you towards itself and you jump to it like anything.

The Flytrap that looks beautiful in appearance but when a fly goes near it, it traps it. Well not in complete literal sense but IT industry can be compared to the Flytrap and the employee to the Fly. It does not kill the employee but the burdens of work do lead to a similar state.

I am not saying that it is the worst industry in the world but what I want to say here is that its not where you think that you would go at 9 in the morning and come back at 7 in the evening keeping work at the office. Its an industry where you might have to work whole night at office or at home.

Every penny you get from an It Firm should earn at least 5-10 times for the firm. Like for example if you are getting 2000Rs a day from an IT firm then the firm expects you to earn 10000Rs a day for it from the Client.

Well, last week I was at my brother’s place in Pune. He and his friends all work for IT industry and they all work like hell to earn their salaries. His friend works in a big MNC in the support side. This guy goes to office at 8a.m comes back at 7p.m, eats his dinner at 8p.m and starts work again at 9p.m with a meeting with the client. This meeting takes sometimes 4-5 hours thus resulting in only a meager of 5 hours of sleep.

Still this guy is happy about this because he enjoys his work. My brother also has a somewhat similar routine but not this hectic but he also enjoys his work.

Thus here I just want to say that IT industry is only for those who enjoy what they do and are ready to adjust with the demands of the industry. It’s not for those who want to earn just a big fat salary Its for those who have a dream about it and not just a simple dream but a dream which is long seen and craved for.

In short I just want to say that don’t choose IT because it gives good salary and that it is booming, but choose it if you think its your dream to be in it. Before you make your choice ask yourself a few questions-

“Is IT for me?”

“Am I ready to face the challenges it throws at me?”

“Will I survive?”

And go for it if and only if you get a positive response from your heart.

Well then Best of Luck!!
