It covers building a campus network with a hierarchical design using access, distribution and core layers. It also discusses quality of service (QoS) implementation in the campus network, WAN and wireless LANs to enable unified communications services.
Advances in IPv6 in Mobile Networks Globecom 2011John Loughney
IPv6 is ready, IPv6 is being deployed. This presentation gives an update on how to use IPv6 in mobile and cellular networks. This provides an update on IPv6 usage in mobile networks. It gives recommendations on what areas are under development and references documents for more details.
This document discusses IPv6 deployment in mobile networks. It motivates IPv6 due to growth in mobile subscribers and IP-based services. The main deployment options are dual-stack and IPv6-only transition solutions. Dual-stack is the standard 3GPP approach and favored option. IPv6 impacts all levels from services to modem hardware. Mobile devices increasingly support IPv6, though challenges remain around DNS configuration and queries.
LBS: Where are we? Where are we going? And how do we get there?John Loughney
1) There is growing consumer and developer demand for location-enabled mobile applications. 53% of consumers want navigation on their phones and the top applications desired are location-related.
2) Nokia's location technologies provide an ecosystem for building location-aware applications, with tools for maps, navigation, and location acquisition from various sources like GPS.
3) Nokia Maps and Traffic applications demonstrate use of location for turn-by-turn navigation and collecting anonymous traffic data from GPS-enabled phones.
Converged Communication and IPv6, afrinic-8John Loughney
The document discusses the growth of mobile internet and communication in Africa and the Middle East. It notes that mobile phone users in Africa have surpassed North America and mobile subscription growth in Africa is 39% annually. The document also discusses that IPv4 addresses will run out and IPv6 is needed for continued growth and convergence of mobile services. IPv6 enables long connections without keepalive messages, reducing infrastructure needs and improving battery life for mobile devices.
This document discusses IPv6 support in 2G and 3G networks. It notes that IPv6 addresses some key limitations of IPv4, including limited address space and complexity from practices like NAT. It outlines IPv6 status in various standards bodies and vendor support. It describes how IPv6 enables important applications in 3G networks like IMS and peer-to-peer applications. It also discusses transition challenges, including the need to avoid NATs between PoC clients and servers due to UDP port timeouts.
"Converged Communications -- Impact and Requirements on future handsetsJohn Loughney
"Converged Communications -- Impact and Requirements on future handsets" at IWPC Session: Future Handset Applications vs. Next-Gen Hardware December 4th - 7th 2007.
http://www.iwpc.org/Workshop_Folders/07_12_Handset_Apps/Handset_Nokia.htm
This document discusses the convergence of communication technologies and the importance of IPv6. 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.
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.
Mobile Terminals as a Driver for IPv6 DeploymentJohn Loughney
Mobile terminals are driving the deployment of IPv6 by requiring a huge number of IP addresses and benefiting from IPv6 features like built-in mobility support, autoconfiguration, and an end-to-end communication model. As mobile devices take on more functions like integrated cameras and support new multimedia services, the growth of data traffic will necessitate an all-IP architecture with sufficient address space like IPv6. Transition mechanisms will allow gradual evolution from IPv4 to IPv6 networks.
Update on current state of 3G and IPv6 deployment .
"The State of 3G/GPRS IPv6 Deployment", North American IPv6 Technology Conference, September 20th, 2005.
This document discusses the benefits of using IPv6 in 3G core networks. It notes that IPv6 addresses the limitations of IPv4, such as limited address space and lack of built-in security and mobility support, which will be important for billions of mobile devices on 3G networks. While transition challenges exist due to existing IPv4 infrastructure, the document argues that 3G core networks should be designed using IPv6 from the start to future-proof the network architecture and simplify interoperability.
