New scenarios for services and applications

Applications and services in IPv6: Current situation

IIP project: IMS and IPTV

IIP project: IMS and VoIP

Conclusions

New scenarios

Advantages of IPv6 for new applications and services:

Address spaceNumber of devicesRe-establishment of an end-to-end communication architectureBetter network management and routing efficiency (larger subnet space) as well as hierarchical route aggregationNo need for Network address translation -NAT

Auto-configuration

Multicast

Mobility

Security

4

Cloud Computing

Source: Forrester Research Inc.

The network goes towards the cloudFrom the beginning: users and serversShare of server resources Grid computingPublic access to the services Service Oriented Architecture

5

Cloud Computing

Limits to the cloudClient server connectionLack of QoSLack of self-managed SOA

Result: Lack of cooperation between elements in cloud computing. Efficiency decreases. We stay in grid!

IPv6 may help since:cooperation protocols for distributed cloud computing requires auto-configuration and self-management (self-managed SOA)simple removal of client-server obligation is not possible in environment with NAT

6

Scenario: Distributed management p2p

Even when P2P networks are distributed networks, their management is centralizedIt results in*:

Need for registration of usersAlso small user groups, which want to share files, must be registered in a service providerLack of integrity in contents

Self-managed distributed management of P2P networks will be acquired only with end-to-end communication and self-managed networks

* We do not consider legal issues (the most important in p2p networks)

7

Internet of Things

In this moment we have „Islands of Things” instead of Internet of Things (e.g. sensor networks)The original business model of IoT included that whatever wherever whenever may have connectivity

Hans Vestberg, CEO of Ericsson, predicted the growth in the number of connected devices to rise from 5 billion to 50 billion by 2020. Much of this connectivity is fuelled by innovative new devices in areas such as e-health and logistics

IPv6 provides connectivity, security, auto-configuration and eliminates NAT barrierThere are thousands of new scenarios for Internet of Things in next fields:

Home networksVehicular networksE-Health networksEducational networksEtc.

8

E-Health

Wireless medical sensor technologies + IPv6 (connectivity + security)= delivering healthcare services at a distance

Remote monitoring of the patients’ health condition and remote care for the elderly and handicapped (wherever they are, whatever they do) significantly improve standards of living

Sensors for real-time physiology (blood sugar, pulse, temperature, galvanic skin response and many others) - systems used to monitor such diseases as cardiac, diabetic, rehabilitation or monitor general health or wellnessAmbient monitoring (e.g. air pollution and humidity) - systems designed for monitoring e.g. patients with allergy or asthma

The removal of NAT allows for easy access for service or/and devices, to perform remote configuration and maintenance – it is important issue for the elderly and handicapped which are living alone

9

Vehicular services

Vehicular networks will provide three types of services:

Road safety (e.g. detection potentially dangerous situations in advance and extending the drivers' awareness of the surrounding environment)Traffic efficiency (e.g. thanks to V2V communication cars can detect an obstacle or traffic jam and avoid it by rerouting)Others (infotainment, fleet control etc.)

IPv6: mobility support and large address space

Approximately number of vehicles exceeds 800 million in the world today. Those vehicles travel billions km:

Let’s them connect together (Vehicle-to-Vehicle V2V) and with devices installed along the roadside (Vehicle-to-Infrastructure V2I), to improve safety and traffic efficiency

10

Current situation: Network operators becoming Content providers

The example of Comcast: Big network operator that tries to integrate users and content servers in seamless end-to-end communicationComcast moved to IPv6 because it was in need of over 100 million addresses (estimations were that within a few years, Comcast would have some 20 million video customers, an average of 2.5 set-top boxes per customer, and 2 IP addresses per box)IPv6 may help the integration of network providers, content providers, service providers (as CDN) thanks to possibility of end-to-end communication More efficiency in content streaming, control of traffic (e.g. load balancing)

Current situation

Google: one unique domain

Telefonica networkProblems with IPv6 users

Closed environment in applications, in opposite of network services

Commercial applications

12

Current situation: Fitness of legacy IPv4 apps&services to IPv6

Changes in IPv6-running apps:Larger IP headers must be considered when computing maximum payload sizeDNS records include, among others: AAAA record typeFunctionalities related to NAT can be ignoredNew socket options:

New functions for passing addressesNew functions for returning addressesNew address structures for API

Changes in „checksum” for TCP and UDP protocolsMemory units for storing addresses (vectors, arrays)New formats for URLs: http://[IPv6_addr]:port/

Increasing popularity of multimedia services

IIP project: Motivation for Multimedia platform

14

IIP project: IPTV scenario

Real Time Protocol (RTP) was designed for IPTV and VoD communicationWhy RTP does not run in the Internet?

NAT breaks end-to-end connectivity, especially in connectionless protocols as UDP (RTP uses UDP)Many NAT traversal techniques exist, but no single method works in every situation since NAT behavior is not standardized

Results: the most of video traffic is sent by http or similarthere is no open IPTV platforms correctly working in the InternetIPTV systems are implemented only on the last mile network (ISP)

IPv6 allows the use of protocols specialized in IPTV and live transmission

15

IPTV scenario

The communication between Service provider and Set-Top-Box is not possible in IPv4IPv6 offers new business models for IPTVBetter QoE, Awareness of User preferences, Optimized advertisingCompanies interested in the investigation of this issue: youtube, BCS global…

16

IPTV scenario

Multicast is mandatory for IPTV in the Internet

In IPv4 Multicast requires additional mechanisms, which generally do not collaborate with network level mechanisms

mechanisms as network level adaptation cannot be provided in Multicast IPv4only application level mechanisms (Scalable Video Coding - SVC, Dynamic Adaptive streaming over HTTP - DASH) are valid in IPv4 scenarios

Results: Application level mechanisms are the unique used within the networkdynamic adjustment of multicast trees could offer better QoE

17

IPTV scenario

In IPv6 there is dynamic adjustment of multicast trees at the network layerNew streaming adaptation may be provided for multicast flows as e.g., network level adaptationThe adaptation may be provided in many points of the network and not only in edge points (better adaptation in multi-domain scenario)

It is easier to provide network awareness for tree adjustment (since multicast is responsibility of the network provider)All the implementations of the IPv6 protocol contain natively Multicast service, so no more hardware is necessary

Conclusions

The current applications and services require no limits in IP layer. IPv6 overcomes some of these limits Current solutions are fully fitted to the IPv4 protocol and, currently, all new scenarios must be adapted to this protocol

Users will acquire more control of the communications, better QoE, more simplified use of the networkNetwork providers will reach more control of traffic, self-management, possibility of expanding to other business modelsContent providers will acquire integrity thanks to end-to-end communication
