2 MACRO TRENDS IMPACTING NETWORKING The cloud is fundamentally changing wide area networks 93% 93% of businesses are using cloud technology in one form or another 1 The definition of a network endpoint is changing There will be 50 billion connected devices by Global IP traffic is growing exponentially Sources: 1 CIO Magazine 2 Statista.com 3 Cisco 3x Traffic to expand 3x by

3 DRIVING INNOVATION IN THE NETWORK Edge WAN Data Center Network Function Virtualization (NFV): instantiate network functions (e.g. routing, firewalls, etc.) as virtual devices From physical to virtual: reduces capital, increases agility and improves turnaround Software-Defined WAN (SD-WAN): SDN implementation in the WAN allows policy-based routing of traffic Optimizes the use of expensive bandwidth while addressing security and SLA concerns Hybrid Cloud Connectivity: secure, dynamic connectivity to connectivity Provides agile connectivity to CSPs without compromising security, aligns bandwidth to cloud service use Move from three-tiered fabrics to two-tiered spine and leaf SDN controllers (e.g. Nuage, NSX) orchestrate and segment data center environments

4 AT THE EDGE NETWORK FUNCTION VIRTUALIZATION Network Function Virtualization (NFV) decouples network functions from dedicated hardware devices and allows these network functions to be hosted on virtual machines (VMs) Traditional Network Appliance Approach Network Function Virtualization Approach Session Border Controller WAN Acceleration Content Distribution Virtual Appliances Orchestrated, automatic, remote installation of VNF PE Router DNS Firewall Standard Servers Standard Storage Specialized, non-commodity hardware Physical install per appliance per site Software-based deployment using common hardware Multiple roles using the same hardware

5 AT THE EDGE DNX NextGen networks VirtualEdge, powered by AT&T FlexWare BENEFITS VIRTUAL EDGE, POWERED BY AT&T FLEXWARE Business Agility Cost Control Reduce CAPEX Replaces H/W appliances with Virtual Network Functions Improved total cost of ownership vs. existing proprietary equipment Future-proofs investment as business evolves Provisioned on a Utility Service Agreement Simplify and Streamline Designed and deployed on the AT&T Integrated Cloud platform that utilizes SDN technologies Uses a standard x86 platform Simplifies your network infrastructure Reduced Complexity Rapid Deployment Agile Networks Addresses need to reduce data center investments and modernize applications Allows network to be as responsive as needed Quick Implementation Uses standardized NFV technology to deploy and manage network infrastructure, devices, and applications faster and more simply
