  • In the last two years, optical networking has risen into the public consciousness in many different ways. It has become the next great technological thing — businesses want it, service providers want to sell it, device manufacturers want to provide equipment, and component manufacturers are scrambling to supply pieces and parts to all of them. At the time of this writing, an 18-month backlog on optical fiber and some optical amplifiers exists because of the enormous and unanticipated demand for highbandwidth optical connectivity.

  • Vertical relationships between government and society still do exist, but almost everywhere they are becoming the exception, rather than the rule. During the last two decades developments in public administration have tended to replace hierarchies. Both in and between organisations, by all kinds of - more or less horizontal - networks, through which the governmental authorities have realised their dependency on the other actors in society.

  • Many researchers have attempted to predict the Enron corporate hierarchy from the data. This work, however, has been hampered by a lack of data. We present a new, large, and freely available gold-standard hierarchy. Using our new gold standard, we show that a simple lower bound for social network-based systems outperforms an upper bound on the approach taken by current NLP systems.

  • This document is intended to help students understand what types of information would be required to pass the CCNA test. This is only intended as a review and additional training and knowledge would be needed in order to take and pass the CCNA exam. This document does not help with the simulation portion of the test.

  • This module provides students with the details about how class inheritance works in C# and explains how to derive new C# classes from existing classes. It explains how to use the method types virtual, override, and new. It briefly explains sealed classes, and then describes interface concepts. Students will learn how to declare an interface and how to implement the two types of interface methods. Finally, the module introduces abstract classes and discusses how to implement abstract classes and methods in a class hierarchy....

  • Objectives: Describe how a hierarchical network supports the voice, and data needs of a small- or medium-sized business. Describe the functions of each of the three levels of the hierarchical network design model, the principles of hierarchical network design (aggregate connectivity, network diameter, and redundancy), and the concept of a converged network. Provide examples of how voice and video over IP affect network design. Select appropriate devices to operate at each level of the hierarchy, including voice and video components.

  • This module provides students with detailed information about reference types. It defines reference types and how they relate to classes. It explains the differences between reference-type and value-type variables. It explains the string type in detail as an example of a built-in reference type. This module also covers the System.Object class hierarchy and the object type in C#, showing the relationships between the various types. An overview of common namespaces in the Microsoft® .NET Framework is provided....

  • JDK 1.5 introduces several extensions to the Java programming language. One of these is the introduction of generics. This tutorial is aimed at introducing you to generics. You may be familiar with similar constructs from other languages, most notably C++ templates. If so, you’ll soon see that there are both similarities and important differences. If you are not familiar with look-a-alike constructs from elsewhere, all the better; you can start afresh, without unlearning any misconceptions. Generics allow you to abstract over types.

  • Microsoft® Windows® 2000 Active Directory™ provides administrators with control over who has access to information in Active Directory. This module identifies strategies for planning the hierarchy of an Active Directory structure that best supports the delegation needs of an organization. The module also discusses how to manage permissions on directory objects and properties. By directly managing permissions, administrators can specify precisely which accounts can access the directory and the level of access that they can have....

  • The routing algorithm of OSPF maintains a complex database of topology information, which routers use to maintain full knowledge of distant routers. OSPF is a classless, link-state routing protocol that is widely deployed in many networks. This chapter will introduce OSPF technologies. OSPF load-balances across four equal metric paths by default on Cisco routers.
