	Social Network Analysis
		Social network researchers measure network activity for a node by using the concept of degrees -- the number of direct connections a node has.
		The good news is that she plays a powerful role in the network, the bad news is that she is a single point of failure.
		Since individuals' networks overlap, peripheral nodes are connected to networks that are not currently mapped.

	What is Social Network Analysis?
		Network analysis is the study of social relations among a set of actors.
		Complete network analysis is where you try to obtain all the relationships among a set of respondents, such as all the friendships among employees of a given company.
		A real problem with network analysis in the past has been the inability to test hypotheses statistically, because the data are by their very nature autocorrelated, violating assumptions of independence (random sampling) built-in to most classical statistical tests.

	Microsoft TechNet: Network Analysis and Optimization Techniques
		During the network baseline study, the analyst should be familiar with the internetwork architecture and aware of the throughput typically achieved in the particular internetwork architecture.
		After the trace analysis data has been saved and the detail trace opened, it is then possible to view the data and locate the low EFT occurrence within the data by cross-mapping the statistical absolute time or hotkey filtering to a low effective throughput event.
		Because the transport layer is essentially in place to establish a network channel for data port communication and, at times, to maintain the communication channel in a consistent and reliable state, it is critical to monitor this area through a network baseline process to ensure connectivity.

	Social Network Analysis
		Social network analysis has emerged as a set of methods for the analysis of social structures, methods which are specifically geared towards an investigation of the relational aspects of these structures.
		Network analysis (or social network analysis) is a set of mathematical methods used in social psychology, sociology, ethology, and anthropology.
		Network analysis is based on the intuitive notion that these patterns are important features of the lives of the individuals who display them.

	Quantitative Methods in Public Administration: Sociometry & Network Analysis
		The term network analysis has largely supplanted the earlier term sociometry, but both refer to the analysis of social networks in part utilizing graphical methods.
		Path diagrams, not necessarily based on actual path analysis, represent variables or groups as circles, relationships (which may be correlations, communications, formal associations, or other interactions) as arrows, and, often, magnitude of relationship by thickness of the arrow.
		Graph theoretic spectra (eigenvalues and eigenvectors allows the researcher to rotate any axis, change any axis, color nodes by categories, and examine the network in 1, 2 and 3-dimensions, and to define new node variables based on eigenvectors and induced partitions, which may be used to examine the network for group structures.

	Amazon.com: Network Analysis, Architecture and Design, Second Edition (The Morgan Kaufmann Series in Networking): ... (Site not responding. Last check: 2007-10-26)
		Network Analysis, Architecture, and Design, 2e, uses a systems methodology approach to teaching these concepts, which views the network (and the environment it impacts) as part of the larger system, looking at interactions and dependencies between the network and its users, applications, and devices.
		Network architecture takes the input from network analysis and provides a high-level view of the network, focusing on the relationships between major functions of the network, such as security, network management, performance and addressing and routing.
		Network engineers who throw capacity at the problem with little analysis should read the book to understand the risks associated with this "methodology." As McCabe states, delay may be as important as capacity; and reliability, maintainability, and availability are often more important than overall throughput.

	Network Analysis
		Network Analysis or Critical Path Analysis (CPA) or the American “Program, Evaluation and Review Technique” (PERT) is one of the classic methods of planning and controlling the progress of projects.
		The next part of the analysis of the network is to find the CRITICAL PATH.
		In such a simple network, it is easy to calculate the amount of slack available for each task, but in a complicated network, it is not easy to 'see' which tasks have slack and which have none.

	Network Analysis
		Content analysis of speeches and written documents is used to clarify the political ideologies and issue positions of different fractions of the power elite.
		For those unfamiliar with the method of network analysis, the basic logic of this approach is quite simple (for an easy to follow introduction, see John Scott, Social Network Analysis: A Handbook).
		In more complex forms of network analysis the links among nodes may be directed (e.g., from A to B) and/or they may be given a value other than one (e.g., to measure the number of shared directors or the amount of money transfered).

	White Papers- Network General - Application and Network Analysis Solutions
		Network management systems separately approach “fault” management, whether something is up or down, from “performance” management, which is a measure of how well something is working.
		Given the convergence of risk factors – more applications and traffic, network sprawl and lower levels of institutionalized network knowledge – it is clear that new management approaches and tools for network analysis are required.
		Traditional tools and methods – which are oriented toward the “point-in-time” capture and analysis of network data or simple “best effort” monitoring of data – are simply no longer powerful enough to address the complexity of today’s network performance challenges.

	How the NSA does "social network analysis." - By Alexander Dryer - Slate Magazine
		In a basic analysis, people are seen as "nodes" and the relationships between them are "links." By studying the links—in the case of the NSA program, telephone calls—it's possible to determine the importance (or "centrality") of each node.
		It's not clear whether such analysis could have been performed in advance, when researchers wouldn't have been certain which links were significant connections to another terrorist and which were casual connections to an acquaintance.
		Google's PageRank system is based on network theory and the concept of "centrality." Doctors use network analysis to track the spread of HIV.

	Network Analysis Infrastructure (Site not responding. Last check: 2007-10-26)
		An analysis infrastructure has the objective to operate beyond the means of network measurements, as it is not good enough to create large data silos containing alot of measurement data that is hardly ever been looked at.
		A non-real-time analysis assumes staggered data collection and data analysis phase, presumably followed by a phase where the analyzed data be transferred to a central location, and the data collection be restarted.
		The analysis infrastructure itself is supported by miscellaneous monitors which collect data, with possibly some local analysis, and results sent to a centralized collector for further analysis and storage.
