This document discusses the need for and drivers towards IPv6 adoption. It notes that new mobile applications and services require more bandwidth than IPv4 allows. IPv6 provides a much larger address space and allows for always-on services without network address translation. The document outlines a phased approach to introducing IPv6 in mobile networks beginning with IPv6 in the user layer and terminal, followed by internal network upgrades. Initial IPv6 deployment is expected in 2003-2007 with a transition period before IPv6 is used mainly from 2014 onwards.
Your media everywhere, anytime. This summarizes end-user expectations when ever-wider broadband and ever-lower flat-rate tariffs combine with users’ thirst for digital content.
The authors describe Ericsson’s end-to-end solution for remote access services, which builds on the IMS and UPnP families of standards, along with the Home IMS Gateway (HIGA), which serves as an intermediary gateway for connecting the device-centric consumer electronics space with the user-centric telecommunications world. The gateway approach leaves
the consumer electronics and telecommunications business models unaffected, while at the same time creating synergies between the two.
The document outlines competencies in mobile and wireless communications including network architectures, network protocols from layers 1-5, the physical layer, and cross-layer design. It provides examples of network architectures like access networks, mesh networks, and sensor networks. It also discusses topics in network protocols, the physical layer including signal propagation and radio technologies, and cross-layer optimization across the protocol stack.
Every once in a while a new technology changes the game. Some benefit from it while others fail to adapt. Long Term Evolution, or LTE for short, is on the surface ,just yet another fast wireless standard bringing us faster mobile networking. But just like the freeway was much more than just a faster road, LTE actually has a chance to change the rules for app developers and create new possibilities.
This document summarizes a presentation about web traffic acceleration solutions from Internap and Jolokia Networks.

Currently, there are number of extensions that are being specified for extending this protocol to support various mobility features. This document provides a brief overview of the protocol features and the deployment scenarios behind these features. Additionally, this document also identifies the developmental efforts within Cisco for building the interfaces based on Proxy Mobile IPv6 on Cisco’s mobile gateway products.
The document discusses the transition from centralized wireless LAN (WLAN) architectures (WLAN 1.0) that rely on controllers to distributed architectures (WLAN 2.0) without controllers. It argues that the rise of high-bandwidth 802.11n networks, increased user mobility, and real-time applications are making centralized control inefficient and a single point of failure. WLAN 2.0 adopts a distributed cooperative control model similar to wired Ethernet with autonomous access points that provide scalability, redundancy and better performance without controllers.
The document discusses the need for unified MPLS networks to efficiently support increasing packet transport demands. It notes that service and revenue models are shifting from circuit-based to packet-based as traffic demands explode. It also discusses how events like cloud computing and LTE deployment are driving adoption of intelligent packet-based networks. Unified MPLS allows for a single end-to-end network that simplifies operations through protocol reduction and separation of transport from service operations. Leading network operators are adopting this approach to build more cost-effective networks that can improve return on investment.

The document discusses IPv6 and mobility protocols. It introduces IPv6 as an updated version of IPv4 that supports more addresses and improved security. Mobile IPv6 (MIPv6) allows devices to change locations while maintaining connectivity using temporary addresses. Hierarchical MIPv6 further improves efficiency for devices that change anchors frequently within the same area. While MIPv6 and HMIPv6 work for many applications, they may not be reliable for real-time applications due to address changes. IPv6 is positioned to support the growing mobile internet.

A presentation given at APRICOT 2016’s Opening Ceremony and APRICOT Plenary 1 session on 22 February 2016.
T-Mobile USA is pursuing an IPv6 deployment strategy to address IPv4 address exhaustion and prepare for continued growth. Their strategy involves deploying dual-stack with NAT44 initially, but targeting an IPv6-only network with NAT64/DNS64 to transition users. They conducted a friendly user trial of IPv6-only which showed most applications working but identified areas like Skype and video chat that were broken. Their lessons emphasize making the business case, engaging enthusiasts, and creating a roadmap while being mindful of security and digital divide considerations.

The transition involves migrating networks to MPLS in phases, starting with aggregation and eventually supporting all technologies over a common MPLS infrastructure.
NTT Communications provides an overview of their IPv6 services and deployment:
- They launched a pre-commercial IPv6 service in 2003 with limited dual-stack routers and tunnels across their backbone. This allowed them to gain experience and prepare for commercial launch.
- Their commercial IPv6 service launched in late 2003 included native IPv6, manual tunnels, and dual-stack options. Since then they have added features but still have gaps in statistics monitoring and firewall/load balancing support for IPv6.
- Their dual-stack backbone has performed well but full IPv6 adoption remains limited due to issues with routing policies, multi-homing, and lack of demand from customers who are primarily early adopters. The drivers for full

Nice presentation by Nokia talking about 5G network and radio enhancements such as 5G Quality of Service, Netowrk Slicing, Latency Reduction and architecture issue. Thanks Benoist for this and your work in 3GPP RAN2.
This document discusses IPv6 transition strategies for service providers. It begins by noting that the IANA pool of IPv4 addresses has been exhausted and regional registries will soon run out as well. While existing IPv4 networks will continue to function, many devices and applications only support IPv4, creating an "IPv4 long tail" that will be challenging to transition to IPv6. The document then evaluates options for service providers, including dual-stack, translators, and tunnels. It provides more detail on implementing a dual-stack infrastructure in the core network using protocols like IS-IS, OSPF, and BGP. 6PE and 6VPE are introduced as options to provide IPv6 connectivity over an IPv4 MPLS

It notes that voice will remain the dominant mobile application in the near future but mobile internet usage is growing rapidly. It also discusses that IPv4 addresses are finite and will run out by 2010, forcing networks to increasingly rely on IPv6. IPv6 allows for long-lived connections without keepalive messages, improving battery life for mobile devices, as converged communication shifts to an all-IP model.
Quality of Service at the Internet Engineering Task ForceJohn Loughney
"Quality of Service at the Internet Engineering Task Force" Workshop on "End-to-End Quality of Service. What is it? How do we get it?" Geneva, 1-3 October 2003.
The document discusses how Nokia is working to enhance communication methods beyond traditional voice calls. It notes that while the mobile phone allows universal connectivity, the ways people communicate are expanding through SMS, instant messaging, email, VoIP and more. However, access to these services is not as universal as voice calls. Nokia's Technology Collaboration Center is working with operators and internet providers to integrate richer content and styles of communication to make connections more natural. The goal is to deploy these enhanced communication technologies more widely to improve interoperability globally.
IP QoS signaling in the IETF:Past, Present and FutureJohn Loughney
The document summarizes the past, present, and future work of the IETF related to QoS signaling. It describes the early work on RSVP and IntServ in the late 1990s. It then outlines the various working groups formed to develop differentiated services, resource allocation protocols, policy frameworks, and sub-IP technologies. Finally, it discusses the Next Steps in Signaling working group, which aims to standardize a new IP signaling protocol to simplify and generalize RSVP signaling, along with its goals and deliverables.
DIANA: Scenarios for QoS based integration of IP and ATMJohn Loughney
This document discusses several approaches for integrating IP and ATM networks to provide quality of service (QoS). It summarizes the Resource Reservation Protocol (RSVP), Scalable Reservation Protocol (SRP), and Simple Integrated Media Access (SIMA) approaches. It also outlines initial experiments on the DIANA platform to evaluate these approaches over ATM networks, including RSVP over ATM signaling, SRP control behavior, and the impact of dynamic SIMA marking. The conclusion is that RSVP over ATM peering has issues while SRP over ATM and SIMA/DiffServ seem more promising for further testing on DIANA in year 2 of the project.
