3 IP Networking Presents Choices
Network-based IP VPN Integrated VPN Storage Web / App Server MPLS VPN AT&T Global MPLS Network Network Based Firewall VPN is delivered over MPLS-enabled backbone and is built in the network cloud. Data Center Internet Premises-based IP VPN Branch Office Remote Offices and Workers Remote Workers Suppliers/Distributors Headquarters VPN is delivered over the Internet, Public IP or Private IP backbone networks, and requires premises devices and utilizes tunneling protocols such as IPSec, Secure Socket Layer (SSL), L2TP and PPTP. Enterprise networking often demands a combination of VPNs with flexible access, levels of management, continuity choices and enhanced features. These technologies are complementary, not competing.

6 AT&T Global Enhanced Network
Plus 600+ US POPs $300M Investment Fully Integrated Supports All Services Common Management Platform Global Processes In-country Personnel This is a map of AT&T’s global Frame and ATM services. This network is also the underlying infrastructure for our Global IP network outside the US (within the US all IP traffic is carried on the AT&T IP Backbone). This is a seamless global network. This network reaches 60+ countries and has 209 nodes and is predominantly frame relay with an ATM core. This network is supported by extensive, in-country support personnel who will now be turning their attentions to supporting the AT&T Enhanced Global Network also. AT&T’s global strategy is to be the number one provider of communications services worldwide. We will drive the speed and creation of innovative new services. We will provide services on a global basis—from customer premises to customer premises. We are building upon our existing global capabilities by to create a new, state of the art, global network using Multiprotocol Label Switching (MPLS). AT&T Global Network is a seamless, ubiquitous network that has been designed on the same state of the art equipment as in the AT&T Frame/ATM network in the US. Use of the same platform and equipment makes it easy to maintain the network and makes it possible for AT&T to quickly deploy services and technologies consistently any where in the world. This network allows us to offer a seamless suite of VPN solutions on a global basis, with MPLS at the core with the ability to offer Class of Services. To provide excellent service to our customers, AT&T uses our extensive staff of in-country personnel and relationships, and select best-in-class management tools and automated processes to create a consistent global network management platform.

7 Leveraging AT&T’s Global Network Strength
AT&T Global Network Strength *Protected by AT&T’s robust Disaster Recovery Program Remote Access from more than 147 countries covered through more than 7,000 POPs and dedicated data access from over 800 POPs in more than 50 countries. *Enables delivery of full breadth of services from a single platform *More than 1,000 nodes supporting MPLS based services *A leading global carrier of IP and data traffic, carrying 4.3 petabytes of traffic per business day *Industry leading SLAs for global IP performance, including best in class assurances for packet delivery, latency, and offering a % e2e assurance *Investment of over $200m to develop AT&T’s integrated Global Enterprise Management System (iGEMS) which provides monitoring of customer networks *Unprecedented visibility & control available through AT&T BusinessDirect R customer portal. Over 400,000 companies, with over 600,000 users now employ the portal to conduct e-sales and servicing transactions The AT&T Global IP Network has been designed with a regional autonomous system structure for scalability and stability; it is considered a wise practice to have regional autonomous systems with very large networks, in order to reduce the size of the routing table in the routers and ensure stability. In addition, in many regions of the world there are communities of countries where the same language as spoken, such as Latin America, and a regional autonomous system structure supports efficient routing for intra-region traffic. The US region of the AT&T Global IP network consists of 34 nodes interconnected by OC48/192 circuits, along with 100 additional nodes connecting smaller cities. We have massive quantities of peering traffic and dedicated IP services can be obtained by any of AT&T’s 600+ US POPs. We were the first ISP to deploy and announce working OC192 link carrying customer traffic. We are also the only ISP with the PeerMon routing stability tool (AT&T Labs has applied for a patent for this tool), which helps keep our network stable and always “reachable” throughout the Internet. The US regional network is MPLS-enabled. Outside the US, we’ve begun a massive upgrade project to upgrade our nodes to an architecture, platform and supporting infrastructure which is consistent with that in the US. This project began in 4Q with our building of our EMEA “core” (8 nodes) and AP “core” (8 nodes). Throughout 2003 and into early 2004 we will continue to upgrade nodes; we expect to complete this project by mid Outside the United States the network consists of several regional autonomous systems, which is considered the best design for network stability and performance. The global regions of the AT&T Global IP Network are also MPLS-enabled. Global MPLS-enabled IP Network at the Core and at the Edge Industry-leading performance: end-to-end reliability, jitter and latency Protected by AT&T’s robust Network Disaster Recovery Program More than 147 countries covered through 7,000+ Remote Access Points
