IPv4 - Addressing

IPv4 supports three different types of addressing modes.:

Unicast Addressing Mode:

In this mode, data is sent only to one destined host. The Destination Address field contains 32- bit IP address of the destination host. Here the client sends data to the targeted server:

Broadcast Addressing Mode:

In this mode, the packet is addressed to all the hosts in a network segment. The Destination Address field contains a special broadcast address, i.e. 255.255.255.255. When a host sees this packet on the network, it is bound to process it. Here the client sends a packet, which is entertained by all the Servers:

Multicast Addressing Mode:

This mode is a mix of the previous two modes, i.e. the packet sent is neither destined to a single host nor all the hosts on the segment. In this packet, the Destination Address contains a special address which starts with 224.x.x.x and can be entertained by more than one host.

Here a server sends packets which are entertained by more than one servers. Every network has one IP address reserved for the Network Number which represents the network and one IP address reserved for the Broadcast Address, which represents all the hosts in that network.

Hierarchical Addressing Scheme

IPv4 uses hierarchical addressing scheme. An IP address, which is 32-bits in length, is divided into two or three parts as depicted:

A single IP address can contain information about the network and its sub-network and ultimately the host. This scheme enables the IP Address to be hierarchical where a network can have many sub-networks which in turn can have many hosts.

Subnet Mask

The 32-bit IP address contains information about the host and its network. It is very necessary to distinguish both. For this, routers use Subnet Mask, which is as long as the size of the network address in the IP address. Subnet Mask is also 32 bits long. If the IP address in binary is ANDed with its Subnet Mask, the result yields the Network address. For example, say the IP Address is 192.168.1.152 and the Subnet Mask is 255.255.255.0 then:

This way the Subnet Mask helps extract the Network ID and the Host from an IP Address. It can be identified now that 192.168.1.0 is the Network number and 192.168.1.152 is the host on that network.

Binary Representation

The positional value method is the simplest form of converting binary from decimal value. IP address is 32 bit value which is divided into 4 octets. A binary octet contains 8 bits and the value of each bit can be determined by the position of bit value '1' in the octet.

Positional value of bits is determined by 2 raised to power (position – 1), that is the value of a bit 1 at position 6 is 26-1 that is 25 that is 32. The total value of the octet is determined by adding up the positional value of bits. The value of 11000000 is 128+64 = 192. Some examples are shown in the table below:

Agile - Primer

Agile is a software development methodology to build a software incrementally using short iterations of 1 to 4 weeks so that the development process is aligned with the changing business needs. Instead of a single-pass development of 6 to 18 months where all the requirements and risks are predicted upfront, Agile adopts a process of frequent feedback where a workable product is delivered after 1 to 4 week iteration.

Roles in Agile

Scrum Master

A Scrum Master is a team leader and facilitator who helps the team members to follow agile practices so that they can meet their commitments. The responsibilities of a scrum master are as follows −

• To enable close co-operation between all roles and functions.
• To remove any blocks.
• To shield the team from any disturbances.
• To work with the organization to track the progress and processes of the company.
• To ensure that Agile Inspect & Adapt processes are leveraged properly which includes
  • Daily stand-ups,
  • Planned meetings,
  • Demo,
  • Review,
  • Retrospective Meetings, and
  • To facilitate team meetings and decision-making process.

Product Owner

A Product Owner is the one who drives the product from business perspective. The responsibilities or a Product Owner are as follows −

• To define the requirements and prioritize their values.
• To determine the release date and contents.
• To take an active role in iteration planning and release planning meetings.
• To ensure that team is working on the most valued requirement.
• To represent the voice of the customer.
• To accept the user stories that meet the definition of done and defined acceptance criteria.

Cross-functional Team

Every agile team should be a self-sufficient team with 5 to 9 team members and an average experience ranging from of 6 to 10 years. Typically, an agile team comprises of 3 to 4 developers, 1 tester, 1 technical lead, 1 product owner and 1 scrum master.

Product Owner and Scrum master are considered to be a part of Team Interface, whereas other members are part of Technical Interface.

How an Agile Team Plans its Work?

An Agile team works in iterations to deliver user stories where each iteration is of 10 to 15 days. Each user story is planned based on its backlog prioritization and size. The team uses its capacity − how many hours are available with team to work on tasks − to decide how much scope they have to plan.

Point

A Point defines how much a team can commit. A point usually refers to 8 hours. Each story is estimated in points.

Capacity

Capacity defines how much an individual can commit. Capacity is estimated in hours.

What is a User Story?

A user story is a requirement which defines what is required by the user as functionality. A user story can be in two forms −

• As a <User Role> I want <Functionality> so that <Business Value>
• In order to <Business value> as a <User Role> I want <Functionality>

During release planning, a rough estimate is given to a user story using relative scale as points. During iteration planning, the story is broken down into tasks.

Relationship of User Stories and Tasks

• User story talks about what is to be done. It defines what a user needs.
• Task talks about how it is to be done. It defines how a functionality is to be implemented.
• Stories are implemented by tasks. Each story is a collection of tasks.
• User story is divided into tasks when it is planned in current iteration.
• Tasks are estimated in hours, typically from 2 to 12 hours.
• Stories are validated using acceptance tests.

When a Story is Done

The team decides what done means. The criteria may be −

• All tasks (development, testing) are completed.
• All acceptance tests are running and are passed.
• No defect is open.
• Product owner has accepted the story.
• Deliverable to the end-user.

What is Acceptance Criteria?

Criteria defines the functionality, behavior, and performance required by a feature so that it can be accepted by the product owner. It defines what is to be done so that the developer knows when a user story is complete.

How the Requirements are Defined?

Requirements are defined as

• A User Story,
• With Acceptance Criteria, and
• Tasks to implement the story.
