NFV - Telco Transformation Unfolded
Telco networks are undergoing a transformation driven by factors like increased capacity demands, network and data center convergence, and the need for programmable networks. This is leading telcos to adopt network functions virtualization (NFV), which uses virtualization techniques to virtualize entire classes of network functions into software that can run on commercial off-the-shelf servers rather than proprietary hardware. NFV aims to provide benefits like elastic scaling, faster deployment cycles, network slicing, and lower total cost of ownership. The European Telecommunications Standards Institute established an industry specification group in 2012 with over 50 members to develop NFV standards. NFV allows operators to reduce costs, improve efficiency, and provide opportunities for energy savings, openness and innovation.

The other radio technologies - why GSM/3G can be complementary and profitable when used with PMR systems.
M2M covers a huge variety of applications and technologies. GSM-based M2M gets a lot of publicity these days as it is seen as the ubiquitous solution for large rollouts, but other radio technologies are often used in critical applications.
There are multiple instances where GSM and PMR are bedfellows and largely it is only the PMR industry that has the sophistication and technical expertise to drive these applications. GSM carriers and app developers struggle to think outside of their own niche, whereas LMR system providers have always had to do a large chunk of their own engineering and development, often taking on the true partner role with their customers, developing on and with them in tandem.
When used in applications that have some or all of these criteria, it is as many times essential as nice to have multiple technologies driving your comms:
- where one mode does not provide the coverage that you need
- where critical public or personal safety issues are involved
- where multiple backup overlays are required because the data is very important and timely
Applications designed for areas like:
- mining - where GSM coverage is patchy at best and PMR is much more effective in a pit
- environment - where delays and breakdowns can cost tens of thousands of dollars or more per hour, where remote-controlled machinery is becoming more common
- personal safety - like lone worker devices
- building and home security - where multiple network paths are now required to achieve the best security ratings and therefore the lowest insurance premiums
- are ideally suited to dual- and multimode technologies
The side benefit of these is that GSM/satellite as an add-on can provide an additional income stream to PMR suppliers as the network providers will pay ongoing revenue shares.

Cisco IPv6 Tutorial
This document outlines an IPv6 lab and techtorial that covers IPv6 addressing, neighbor discovery, static routing, OSPFv3, BGP, and tunneling. The agenda includes lectures on these topics as well as corresponding labs to provide hands-on experience. Prerequisites for the session are basic network engineering knowledge and interest in Cisco technologies. The document then goes on to describe IPv6 addressing formats, types of addresses, and how addresses are allocated to interfaces.
Wimax
This presentation provides an overview of WiMAX (Worldwide Interoperability for Microwave Access) technology. WiMAX is a wireless communication standard that can provide broadband access over long distances in a flexible, easy to install way. It works through connections between WiMAX towers and receivers. There are fixed and mobile versions, with mobile WiMAX allowing broadband internet from anywhere. WiMAX offers advantages over traditional broadband and WiFi like lower costs and broader coverage. The presentation predicts that within 5 years, WiMAX will be the dominant wireless technology for both fixed and fully mobile broadband networking.
Wimax / ieee 802.16
The WiMAX MAC encapsulates data packets from higher layers through various sublayers. It adds headers at each sublayer for functions like security, bandwidth allocation, and multiple access control before the data is encoded and transmitted through the physical layer using modulation schemes like OFDM. This ensures efficient transmission of data over the wireless medium according to QoS priorities and security requirements.
IPv6
Overview of IPv6 protocol along with various transition scenarios for the migration from IPv4 to IPv6
IPv6 is the current and future Internet Protocol standard. As anticipated, IPv4 addresses became exhausted around 2012.
The IP address scarcity is the main driver for IPv6 protocol adoption.
IPv6 defines a much larger address space that should be sufficient for the foreseeable future, even taking into account Internet of Things scenarios with zillions of small devices connected to the Internet.
IPv6 is, however, much more than simply an expansion of the address space. IPv6 defines a clean address architecture with globally aggregatable addresses thus reducing routing table sizes in Internet routers.
IPv6 extension headers provide a standard mechanism for stacking protocols such as IP, IPSec, routing headers and upper layer headers such as TCP.
ICMP (Internet Control Message Protocol) is already defined for IPv4. ICMP was totally revamped for IPv6 and as ICMPv6 provides common functions like IP address and prefix assignment.
Lack of business drivers for migrating to IPv6 is responsible for sluggish adoption of IPv6 in carrier and enterprise networks.
Numerous transition mechanisms were developed to ease the transition from IPv4 to IPv6. Many of these mechanisms are complex and difficult to administer.
The transition mechanisms can be coarsely classified into dual-stack, tunneling and translation mechanisms.
IPv4 to IPv6
Various technologies in IPv4 and IPv6.It also includes the relationships between these two and migration from previous to later
WiMAX Basics
Definition:WiMAX is a fourth generation (4G) technology.WiMAX stands for Worldwide Interoperability for Microwave Access.WiMAX is technically also known as “IEEE 802.16”WiMAX is a wireless communications standard designed for creating Metropolitan Area Networks(MANs).A Broadband Wireless Access(BWA) technique offering fast broadband connection.It allows a user, to browse the internet on a laptop without physically connecting it to a router.It involves microwaves for the transfer of data wirelessly.Founded by Ensemble, CrossSpan, Harris & Nokia.
Wimax
WIMAX is a wireless technology that provides broadband connectivity over long distances in a variety of ways. It uses towers to transmit high-speed internet access to receivers within a range of up to 50 km. WIMAX has several advantages over existing wireless technologies like WiFi and 3G, such as higher speeds, broader coverage areas, and lower infrastructure costs. While WIMAX adoption is still in early stages, it promises to deliver wireless broadband to more users at lower prices than current options.

IPv6 Adoption --- Acceleration
IPv6 adoption is accelerating due to growing challenges with IPv4 addresses and the increasing number of internet devices. Carrier grade NAT (CGN) solutions are being used to share public IPv4 addresses but negatively impact user experience. IPv6 deployment avoids these issues by providing each user with a unique IP address and allows the "full spectrum" internet. Global IPv6 deployment is now doubling every 9 months with some networks seeing 10-15% of users on IPv6. Full deployment is forecast within the next 5 years and will be required to support continued internet growth.

Introduction
Internet Protocol from 6 (IPv6) is the late conformity of the Internet convention and the fundamental model of the convention will be thoroughly utilized. IPv6 is genuinely a new drawing nearer closer tradition made to join all the possible needs associated with prospective web that apparent as Internet shape 2. This convention has its herald IPv4, limits for the framework level .3. In addition to their giving of a huge amount of sensible location region, this protocol offers sufficient attributes to address the disadvantage of IPv4.
As of recently, IPv4 has confirmed independent from anyone else like a capable routable tending to convention and offered every one of us for a long time upon their best-exertion conveyance framework. It had been produced in the before 80s and would not acquire any imperative alteration later. Amid the season of their introduction to the world web has been confined essentially to some instructive establishments for their examination and to the division of assurance. Alongside IPv4's location zone weakness, IPv6 is as of now tackling the administration or supervision of web, which is some of the time called Internet form 2. On June 06, 2012 the web organization formally discharged IPv6. Today numerous ISPs have been giving IPv6 upon open site and need to keep up this executed. Each of the device makers likewise partook to give IPv6 naturally permitted on items. This is a stage to persuade web organization to move to IPv6.
IPv6 Variations
· By completing this new tradition the area degrees get extended, which can help to convey plus or minus three hundred and forty trillion stand-out IP addresses.
· To grow the guiding efficiency the header is more made strides.
· Extension and decisions support are fused to engage all around sorted out sending.
· Also develop the affirmation and payload embodiment.
Why is IPv6 Required?
As everyone is careful that the IPv4 convention is missing the mark on its area space. Since one another day over the world, there is an augmentation in the use of PC's, mobile phones, tablets, gaming structures, and diverse machines which expected to join with the web. With its 128-bit area position, IPv6 can reinforce 3.4 x 1038 or 341,283,365,92,1938,464,465,372,608,432,764,212,459 novel IP addresses. Moreover, differentiating and the IPv4 convention the area range is adequately broad to plan an intriguing area on every contraption.
Impact of Migrating to IPv6
The move has begun in perspective of the essential and the requirement for improvement of area space for inevitable applications. Fig.2 identifies with the development-organizing model. Early on step is to get ready for IPv6 to ensure business movement. Game plan step should be all that much organized, so that layout and assembling doesn't end up being pointlessl ...

IPv6: Early Mover Advantage?
1. Tata Communications has been an early adopter of IPv6, with its acquired companies Teleglobe and Tyco providing some of the first IPv6 connections in the late 1990s.
2. IPv6 adoption has not taken off as quickly as expected, with only minimal IPv6 traffic currently, but Tata Communications believes early IPv6 support provides them an advantage over competitors.
3. Further catalysts are still needed for widespread IPv6 adoption, such as improved DNS and network management support, as well as more IPv6-enabled applications and content. The growth of mobile internet may be the trigger that drives more rapid IPv6 deployment.

Non symbolic base64 an effective representation of ipv6 address
The document discusses the transition from IPv4 to IPv6 due to the depletion of IPv4 addresses. It proposes a new scheme called Effective and flexible representation Of IPv6 with Base64 to represent IPv6 addresses in a more compact notation of 28 bytes instead of the standard 39 bytes. This is done using the period as a delimiter instead of the colon in IPv6 addresses and using Base64 in a non-symbolic way. The scheme aims to address issues with long IPv6 addresses like memory usage, bandwidth and latency. Cloud computing will benefit from the more compact and user-friendly representation of IPv6 addresses.
