The National Lambda Rail is a US national distributed facility that is based on leased optical fiber and was deliberately designed and developed not as a network but as an infrastructure that could support multiple different types of networks, including experimental research networks. A key characteristic of the NLR is its ability to support many distinct networks for the US research community with the same core infrastructure. Using the NLR, experimental and productions networks can be implemented within the same facilities but can be kept apart physically and operationally. For some communities, the NLR provides production-level services for advanced applications, with guaranteed levels of reliability, availability, and performance. For other communities, the NLR provides researchers with capabilities for implementing experimental networks, including national-scale testbeds, and deploying and testing of new networking technologies, without the usual restrictions of production networks.

The method for the determination of limiting molar conductivities of electrolytes KI was discussed in Section 7.1. The limiting molar conductivities of individual ions kI can be obtained by the following methods. i

The basic principle behind HARQ for HSUPA is the same as that for HSDPA. After each transmitted TTI the Node B indicates to the transmitting UE whether the packet was received correctly or not. In the event of incorrect reception the UE will retransmit the packet. The Node B tries to recover the packet by combining the energy of the retransmission with previous transmissions until the packet is received correctly or the maximum number of retransmissions is reached. The HSUPA HARQ may either use Chase combining where each retransmission is an exact copy of the initial transmission, or incremental redundancy where retransmissions contain additional redundancy bits for the initially transmitted bits. The main di erences between HARQ with HSUPA and HARQ with HSDPA are that HSUPA HARQ is fully synchronous and, with incremental redundancy, even transmitted redundancy versions can be predetermined; it also operates in soft handover. HARQ for HSUPA is discussed in more detail later in this chapter.

DOWNSIZING: WHEN IT DOES AND DOES NOT WORK Downsizing at its worst perhaps is best represented by Albert Chainsaw Al Dunlap, who had a penchant for a clear-cut approach to job cuts and undertook his final downsizing effort at Sunbeam Corporation. Dunlap s goal was to lift the
