El documento describe la historia y características de IPv4 e IPv6. Explica los problemas con IPv4 como la escasez de direcciones IP disponibles y las soluciones propuestas como CIDR y NAT. También compara las cabeceras y características de IPv4 e IPv6, y resume las fases de implementación de IPv6 según el Plan de Transición de Internet. Finalmente, resume varios proyectos y experimentos de despliegue de IPv6.
Internet Protocol version 6 (IPv6) is the latest version of the
Internet Protocol (IP), the communications protocol that
provides an identification and location system for computers
on networks and routes traffic across the Internet.
IPv4 & IPv6 are not designed to be interoperable, complicating
the transition to IPv6. However, several IPv6 transition
mechanisms have been devised to permit communication
between IPv4 and IPv6 hosts.
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.

Cisco ACI: A New Approach to Software Defined NetworkingZivaro Inc
Cisco ACI: A New Approach to Software Defined Networking, presented by Michael Edwards from GTRI. Learn more about Cisco's Application Centric Infrastructure (ACI). As a policy-based automation solution, Cisco ACI is a different approach to Software Defined Networking (SDN). This presentation uncovers what makes it simple, agile and application centric, and how it can reduce errors and accelerate application deployment from weeks to minutes.

Esta es una presentación que explica en detalle el funcionamiento de STP... de esta hice una traducción, pero el contenido, el modelo en fin la mayoría de información en ella no es de mi autoria.
Solo hice traduccion y algunos retoques.
Espero la disfruten!

This Slides were exposed on XII Jornadas de Ingeniería de Telecomunicaciones, UCAB 2014 (Caracas, Venezuela), and show what is the new protocolo IPv6, and what are the mechanism designed for transition to the new Internet (IPv6) from the actual with IPv4.
IP Versión 6 (IPv6) o IP Next Generation (IPng). IP versión 6 (IPv6) es una versión de IP (Internet Protocol), diseñada para ser la sucesora del protocolo IP que conocemos actualmente (IP versión 4 o IPv4).
Como consecuencia del crecimiento exponencial en el número de usuarios de Internet, los proveedores de servicio se han enfocado en la búsqueda de soluciones para lograr que sus arquitecturas de red satisfagan la creciente necesidad de servicios, terminales y aplicaciones. Con tal fin se diseño la versión 6 del protocolo de Internet (Ipv6), la cual ha permitido un nuevo sistema de direccionamiento basado en una mayor cantidad de direcciones. Ipv6 prevé un aumento comercial del internet alrededor del mundo y permite que cada dispositivo cuente con su propia dirección de internet, lo que facilita la comunicación móvil, mejora la seguridad de extremo a extremo y la calidad de servicio.
En el presente ensayo, analizaremos algunos informes internacionales que hacen referencia al cambio de protocolos en los diferentes países del mundo y tratar de sacar conclusiones y ver la diferencia acerca de IPv4 e IPv6.

IPv4 market ¿Se va a crear un mercado financiero para el espacio de direcciones IPv4? * ¿Va a demorar la transición a IPv6 porque se dispone de más direcciones IPv4? * ¿Se realizarán las transferencias de direcciones IPv4 del núcleo de Internet con routers de la tabla de rutas de los ISP? Stanford retornó más de 16 millones de direcciones IPv4 en el año 2000.
