SIP-IETF Internet is willing to eat its own children as well as the children of others. It isnt apparent that any telco/cablecos innovations are eating any Internet children. 1.Telco/Cable co's physical connectivity 2.Internet services 3.Upper layers: highlight the Telco/Cable co struggle at services. 4.Lower Layers: Telecom industry innovation has been centered on basic transmission technologies (e.g., DWDM, EDFA, DSL, GSM) 5.Sometimes innovation stays within an eco-system and can be quite successful within it: SMS (what about IM), SIP (what about non-SIP) 6.Things change over time. -> AOL -> Gmail P2P

Via existing standardized lower networking layers, anyone can now download and install the software needed to use such new innovations driving concepts such as social networking and P2P. That's a key reason new innovations can reach critical mass so quickly. A recent example is SIP IMS BitTorrent XMPP Skype Gnutella Defacto Joost Will SIP cross-over? IMS possibilities? Moving this way?

Consider an evolution about relationships Mashups P2P Encryption People technology Creating: Blogs, user generated content, podcasts Connecting: Social networks, virtual worlds Collaborating: Wikis and Open Source Reacting to others: Forums, Ratings, Reviews Organizing content: Tags Staying aware: RSS, widgets and Twitter Cloud computing (XMPP) Traffic Scattering Network coding Many of these technologies have demonstrated considerable end-user value (for example, Bit Torrent, Skype, etc.) but many areperceived to provide little or no value to the restrictive competition eco-system. Other related issues: 1.Infrastructure costs! 2.Privacy concerns! 3.Missing services/functions? MashupsP2P

Centralized: delivered and controlled by a server Distributed: Built on demand, distributed and controlled by the end user devices Is current core network controlled thinking about applications becoming obsolete? e.g. IMS, SIP and DPI technologies are designed around an application infrastructure supporting paradigm Mashups and P2P technologies

All other product or service names are the property of their respective owners. © Motorola, Inc Technology Trends: Titan vs. Titan 11 P2P (edge to edge) Anyone can offer a service to anyone else! Mainly Involves: Sharing of resources by direct exchange (NO man in the middle!), Ability to self organize (NO control from the middle!), Deal with intermittent connectivity (NO state maintained or master data base in the middle!), …of the peers, for the peers, by the peers

Centralized: IMS and SIP Distributed: P2P and IM We are moving from an early technology world where we had to talk to machines in their language to an emerging world where machines will talk to us in our language Will IM be the future control paradigm? If so? …should we run language parsers underneath?

Centralized: Circuit Switched network is easy Data network: Session Border Controller (SBC)* as the point of convergence for VoIP packets. Implementing LI on SBC is the VoIP equivalent of wire tapping on a circuit switched network. *SBC is typically a VoIP session aware device that governs the manner in which VoIP calls are initiated, conducted and terminated in a network. Distributed: VoIP IP provides numerous methods to ensure data security. no standardized manner to distinguish voice packets no telling which path the IP packet will take what headers get added. Decentralization is effecting LI too! BTW: this is all true for any kind of traffic

NFC What could STBs see? Bluetooth(R) a b/g GSM/GPRS CDMA IR RFID GPS UWB WiMAX UMTS TV / Radio Etc. NFC The world is increasingly connected What could end-users see? Traffic scattering

15 MOTOROLA and the Stylized M Logo are registered in the US Patent & Trademark Office. All other product or service names are the property of their respective owners. © Motorola, Inc Technology Trends: Titan vs. Titan 15 Network Coding Network coding is a field of information theory and coding theory and is a method of attaining maximum information flow in a network The core notion of network coding is to allow and encourage mixing of data at intermediate network nodes. In contrast to traditional ways to operate a network that try to avoid collisions of data streams as much as possible A receiver sees these data packets and deduces from them the messages that were originally intended for the data sink. This is an elegant principle that implies a plethora of surprising results Is current core network controlled thinking about packets becoming obsolete?

16 MOTOROLA and the Stylized M Logo are registered in the US Patent & Trademark Office. All other product or service names are the property of their respective owners. © Motorola, Inc Technology Trends: Titan vs. Titan 16 QoS How can QoS work today and in the future? ….when you consider… Emerging future: overlay techniques (P2P), mashups, traffic scattering, network coding. Encryption or use packet-obfuscation Lowest prioritization for all encrypted traffic? – Privacy is systematically discriminated against. Most of the time the SERVERS ARE SLOW and NOT the network. Low Utilization is a fundamental part of network design Redundancy for reliability. Capacity for peak loads. What does it mean to run a link/box at 10%? Race with Moore's Law Link queue can empty faster than you can run instructions to make QoS decisions. QoS adds complexity Fiber capacity shifts bottlenecks from pipes to nodes and because of the enormous fiber speeds available, adding node queues to the mix of things that need to be QoS configured and managed doesn't appear to simplify the QoS challenges. Where is the ROI? etc. QoS is NOT an adequate substitute for capacity and potentially makes a bad situation much worse

All other product or service names are the property of their respective owners. © Motorola, Inc Technology Trends: Titan vs. Titan 17 L1 L2 L3 L4 L6 L7 L8 L9 L10 Restricted CompetitionOpen Competition Finance Politics Religion System-Based Innovation Component-Based Innovation Networking Protocol Layers L5 Why this fixation about control? It is rooted in scarcity concerns about the capacity of the physical layer infrastructure...and desires by some to control end user behavior Other related issues: 1.Infrastructure costs 2.Missing services/functions 3.Privacy concerns Is the real challenge managing scarcity and end user behavior? …or simply keeping up with technologys ability to satisfy growing demand. Evolution driven by Moores Law Twisted light: excess of 560 Gbps on a single wavelength in a DWDM system today In the near future it is expected that data rates in excess of 1000 Gbps per wavelength will be possible Optical Orbital Angular Momentum (OOAM) has the potential to add an almost infinite number of phase states to the modulated signal and further increase the capacity to thousands of terabits. The number of wavelengths (colors) on a fiber is currently around 80 and climbing The number of fibers between Internet peering points is approx 200. OK …you do the math! …looks like the optical to electronic bottleneck makes it impractical to practice network management in the core networkhttp://www.iop.org/EJ/article/ /9/9/328/njp7_9_328.html#nj250899s1http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber= This results in a quest to manage all the traffic at the higher layers to prevent network resource depletion To avoid a network wide meltdown Irrational fear? – I see this perspective hidden in the termNetwork Management which is a code word for control

18 MOTOROLA and the Stylized M Logo are registered in the US Patent & Trademark Office. All other product or service names are the property of their respective owners. © Motorola, Inc Technology Trends: Titan vs. Titan 18 At the Heart of the thing known as The Internet Its an environment that fosters experimentation Clearly "the place" for innovation of communication services Seems to be about the absence of impediments The lack of impediments seen in one eco-system and not the other appears to be making a huge difference in where innovation (and the associated wealth it generates) will be most successful. More experimentation then more luck! More $$$! A major part of innovation is what we can call unexpected usage (or luck). However, the luck seems to be on the Internet side these days. Application-independent, TCP/IP or UDP are the backbones of the end-to-end nature of the Internet. If history is any guide, a betting man would probably look for the next large market cap company to be about services and come from the Internet eco-system.

19 MOTOROLA and the Stylized M Logo are registered in the US Patent & Trademark Office. All other product or service names are the property of their respective owners. © Motorola, Inc Technology Trends: Titan vs. Titan 19 A Major Challenge for those stuck in the past of Networking…. How can any technology which relies on extensive core network control and takes an application focus and consider packet information invariant, adapt to overlay techniques found in P2P networks, traffic scattering, network coding, the increasing use of encryption, the emergence of cloud computing, as well as trends related to dynamically composed and instantiated concoctions (formally known as applications) at the edge of the network? The web is becoming THE programming development platform. Now, many view the web as the ultimate programming platform that helps all of humankind

You should ask for: …the serenity to accept the things I cannot change (attempts to control the Internet), the courage to change the things I can (business cases that ignore reality), …..and most importantly… …the wisdom to know the difference!
