Volume 1, Section 5.1: Managed Tiered Security
Enterprise SM VOLUME 1, SECTION 5.1: MANAGED TIERED SECURITY SERVICES Enterprise SM 5.1 MANAGED TIERED SECURITY SERVICES [C.2.7.4, M.2.1.3] Level 3 will support the GSA’s Multi-Tier Security Profiles (MTSP) initiative in accordance with Tier-2 – Protected Service specifications. We teamed with one of the world’s leading Managed Security Services providers, , to offer one of the most complete and reliable Managed Security Solutions available. Our solution is designed to meet or exceed the Government’s requirements for MTSP Tier 2 service, as defined in RFP Section C.2.7.4.1.1.2. A description of our offering is provided below. Responses to the requirements of RFP Section L.34.1.6 follow. The Level 3 MTSP Tier 2 solution includes the Help Desk function specified for Tier 1 service, and additional technical and management components to support security needs of Sensitive but Unclassified (SBU) mission functions and information. Our Managed Tiered Security Service (MTSS) offering will provide a vehicle for agencies to order individual managed security services a la carte or in a bundle. The components include: Volume 1, Section 5.1 Page 667 Rev. 3-5-2007 Managed Tiered Security Services TQC-JTB-05-0002 © 2007 Level 3 Communications, Inc. All rights reserved. Use or disclosure of data contained on this sheet is subject to the restric ions on the title page of this proposal. Enterprise SM Agencies will gain efficiencies and cost savings through service bundling, versus ordering any of the Managed Security Services a la carte. -

They both have the position as ‘mainport’; an international gateway for physical products and passengers. This importance of these mainports for the Dutch economy is on two levels. First, they have a direct impact on the economy, for instance through employment of people working at the container terminals in Rotterdam or at Schiphol airport. In addition, there is also an indirect effect as these mainports attract various -

The Great Telecom Meltdown
4 The Internet Boom and the Limits to Growth Nothing says “meltdown” quite like “Internet.” For although the boom and crash cycle had many things feeding it, the Internet was at its heart. The Internet created demand for telecommunications; along the way, it helped create an expectation of demand that did not materialize. The Internet’s commercializa- tion and rapid growth led to a supply of “dotcom” vendors; that led to an expec- tation of customers that did not materialize. But the Internet itself was not at fault. The Internet, after all, was not one thing at all; as its name implies, it was a concatenation [1] of networks, under separate ownership, connected by an understanding that each was more valuable because it was able to connect to the others. That value was not reduced by the mere fact that many people overesti- mated it. The ARPAnet Was a Seminal Research Network The origins of the Internet are usually traced to the ARPAnet, an experimental network created by the Advanced Research Projects Agency, a unit of the U.S. Department of Defense, in conjunction with academic and commercial contrac- tors. The ARPAnet began as a small research project in the 1960s. It was pio- neering packet-switching technology, the sending of blocks of data between computers. The telephone network was well established and improving rapidly, though by today’s standards it was rather primitive—digital transmission and switching were yet to come. But the telephone network was not well suited to the bursty nature of data. 57 58 The Great Telecom Meltdown A number of individuals and companies played a crucial role in the ARPAnet’s early days [2]. -

Importance of Ixps to Development of the Internet in the Caribbean White
White Paper (DRAFT) on Internet Exchange Points Importance of IXPs to Development of the Internet in the Caribbean By Bevil M. Wooding Importance of IXPs to Development of the Internet in the Caribbean White Paper (DRAFT) by BEVIL M. WOODING (Internet Strategist, Packet Clearing House) Executive Summary Accelerating the spread of the Internet, encouraging development of Internet-based economic activity and reaping consequent social benefit in the Caribbean is dependent on reducing Internet connectivity and bandwidth costs and improving quality of service. The Internet Exchange Point (IXP) is an internationally recognised mechanism for achieving cost and service gains and ICT sector growth. An IXP is a location at which Internet Service Providers (ISPs), in country or locality, exchange domestic Internet traffic domestically between their customers on a cost-neutral basis. By so doing ISPs avoid having to send domestic-bound traffic across expensive international transit providers. At present there are only three relatively small IXPs in the Caribbean region, all activated within the last 6 months. As a result, nearly every Caribbean ISP must rely on expensive international transit providers for connectivity. Among the central inhibitors to IXP deployments in the Caribbean are: 1) Dominant Telecom Operators & ISPs - misguidedly seeking to obstruct effective competition 2) Legal Provisions - ranging from burdensome tax treatments to prohibitions on non-regulated telecommunications facilities and restrictive licensing regimes. 3) Regulatory -
