2. The IBM Environment The IBM Network • 20,000 Routers, switches, firewalls • 14,000 wireless LAN access points • 365,000 wireless LAN subscribers • 350,000 remote access users • 2099+ Terabytes WAN traffic per month Network Drivers • 500,000+ employees globally • 800+ Office locations • Presence in 170 countries • Security Controls • 1.3M laptops/desktops in total • 30,000 Blackberry smart phones via enterprise BES • 225,000 IP hard phones at 337 sites • 2.4B minutes of audio conferencing annually • 10,000 shared networked printers • 600M printed pages annually • Bandwidth to support 100 immersive video conf rooms 2

3. EXECUTIVE SUMMARY: NETWORK STRATEGY FOR 2011-2015 Mission: Maintain IBM’s global network as a foundational element of a Globally Integrated Enterprise. Enhance alignment with global strategic data centers and meet access requirements of a global workforce as well as partners, suppliers, and customers. Respond to increasingly sophisticated security threats while reducing overall security costs. State of Network in 2011 State of Network in 2015 Top Core Infrastructure Services Initiatives • Deploy High Speed Core and Server Access and implement network virtualization as a part of the replacement of End of Life LAN equipment. • Upgrade Wireless LAN for greater capacity, addition of 802.11n, and migrate to controller-based technologies for enhanced security, reliability, and capacity. • Deploy IPv6 to meet industry requirements for customer/partner access and product support. • Deploy WAN Acceleration technology to improve performance and reduce demand growth. Top Metrics Describing the End State • LAN hardware refreshed in the core, server, and wireless access areas for improved capacity and stability • WAN traffic grows to over 5000 Terabytes per month with expanded coverage to meet expansion into GMU • Operational service levels improved through equipment refresh and completion of Blue Sky transition • New services can be introduced to the network through better technology and process integration with AT&T Top Metrics Describing the Initial State • Global LAN network with aged devices - 20K Routers, switches, firewalls - 14K Wireless Access Points - 16K End of Life by 2015 • Global WAN carries 2099+ Terabytes of traffic per month • Operational service levels generally meeting needs • Deployment of new services delayed by Blue Sky transition Top Underlying Beliefs and Assumptions • The Network infrastructure is a key foundation for IBM as a globally integrated enterprise, and must meet the diverse needs for connecting employees, customers, and suppliers/partners to IBM services and applications. • The network provides integrated security services as a component in the enterprise security architecture through access control, authentication, flow management, and malware prevention. • Network traffic growth will continue, driven by increases in customers and employees, richer media, and the addition of smarter devices to the network. • Network service rates will continue to decline to partially offset growth in demand, based on cost improvements in hardware/software components as well as bandwidth. 3

4. Wireless Focus for Client Growth • Smartphones outpacing laptops for new purchases in consumer market • Enterprise Smartphone offerings being established to support secure access to IBM applications and Internet - Notes Traveler (iNotes), Sametime Web, W3 • 250K Smartphone Offering users expected • Smartphones in IBM offices will naturally connect to the IBM WLAN first (instead of cellular), if available IBM Wireless enhancements in support of Client Growth... • Complete dual-band 802.11n coverage using newer Controller based technology • Dual-band for improved performance in mixed environments – 802.11b/g, 802.11a, 802.11n • 802.11n for up to 300 Mbps throughput • Controller wireless for fast roaming, improved setting management and optimization • Automatic RF interference detection and adjustment • Increase IP address capacity • New site surveys for optimal WAP placement and settings • Internet Connect (wireless Internet hotspot) in conjunction with IBM Wireless • May require User Access layer upgrades for Power over Ethernet (PoE) and 1G WAP uplinks Simplify Wireless / Improve Client Experience • Sunset B radio and WEP and WPA-TKIP encryption support • Migrate to digital certificates leveraging IBM internal certificate authority for client authentication As market solutions mature, incorporate newer protocols and settings voice and real-time applications

5. IBM Voice and Communications Strategy

6. Voice Comparison – Strategic Considerations Voice Landscape Will Change Significantly Over Next 24 Months • Voice (and video) integral to wide range of user capabilities • Well integrated, seamless and must be globally available • Significant new vendor UcaaS cloud based offerings: UC applications Team Collaboration service Conference scheduling Social Networking service Phone presence e-mail and Calendaring service Unified Messaging IM and Presence service Phone presence UC integration Web Conferencing service Ad-hoc conferencing Tablets Integrated Video Desktop Video Conferencing service Unified Messaging service Integrated Audio and Presence Enterprise Telephony service Audio Conferencing service People and Devices Real Time Infrastructure Integrated UC and Social Applications

7. Business requirements, have been distilled into over-arching strategic principles and mapped onto our framework Simplified work place services framework • Unifiy communications and collaboration • Voice (and video) integral to wide range of user capabilities • Well integrated, seamless and must be globally available • Support social collaboration applications • Information-Centric Infrastructure Management • Manage and optimize current service offerings; forecast future conditions; model and predict the impact of changes • Minimise IBM Infrastructure • Shift to mobile technology enables reduction of fixed infrastructure in IBM sites • Shift to use services in cloud model can reduce fixed infrastructure • Limit IBM infrastructure to high value add capabilities • One Phone / Identity Concept • Match the IT tools to the work that the employee needs to perform • Increase employee ease of use and productivity • Reduce Total Cost of Ownership (TCO) Key strategic principles
