Onesource date March 2009 Namespace based Validation Dispatching Language NVDL is an XML schema language for XML Validation validating XML documents that integrate with multiple XML Namespace namespaces . It is an International Organization for Standardization ISO International Electrotechnical Commission IEC standard, and it is Part 4 of the Document Schema Definition Languages DSDL schema specification. Much of the work on NVDL is based on the older NamespaceRoutingLanguage . Validation Most XML languages are based on a single XML namespace. The expectation in these cases is that XML elements in a particular namespace belong to that language, and elements in another namespace belong to another language. Many XML languages allow the use of arbitrary elements from other namespaces. The problem arises during the attempt to validate these hybrid documents. Each language is defined by a specific XML schema, but there is no linkage between the schemas. The purpose of NVDL is to provide that linkage, based on namespaces.

A Global Namespace is a heterogeneous, enterprise wide abstraction of all file information, open to dynamic customization based on user defined parameters. This becomes of particular importance as multiple network based file systems proliferate within an organization the challenge becomes one of effective file management. A Global NameSpace GNS has the unique ability to aggregate disparate and remote network based file systems, providing a consolidated view that can greatly reduce complexities of localized file management and administration. For example, prior to file system namespace consolidation, two servers exist and each represent their own independent namespaces e.g. server1 share1 & server2 share2. Various files exist within each share respectively, however users have to access each namespace independently. This becomes an obvious challenge as the number of namespaces grows within an organization. With a GNS, an organization can access a virtualized file system namespace e.g. files now exist under a unified structure, such as company.com share1, share2 where the files exist in multiple physical server share locations but appear to be part of a single namespace. Some of the main reasons behind a GNS is to open up more storage pools for larger working pools of disk, migrate data transparently, and reduce number of mount points shares in an environment. Vendors implement this technology in different ways, but the client view is designed to be the same.

No footnotes date March 2010 In Windows shell Windows Shell programming , the Windows Shell namespace is an organized tree structured hierarchy hierarchical representation that Windows Explorer facilitates to graphically present file system contents and other objects to the end user. Conceptually, the Shell namespace may be regarded as a larger and more inclusive version of the file system. The Shell namespace is a hierarchical tree that consists of the wide variety of objects that make up the system. Specifically, the Shell namespace consists of two basic types of objects, namely files and folders. Folder objects, which are containers for file objects and other folders called subdirectories, are the nodes of the tree, while file objects are the leaves of the namespace tree. Objects in the Shell namespace can represent physically stored file system objects such as files and folders, or can be virtual objects such as the My Network Places and Recycle bin computing Recycle Bin virtual folder virtual folders . The folders and data files that reside on physical computer disk drives are the most numerous and familiar of these objects although, through Windows Explorer Extensibility extensions the Shell also provides access to various virtual objects that may not involve physical storage at all. Consequentially, there are folders that do not reside on the physical file system, which are referred to as virtual folder virtual folders . Likewise, there are virtual file objects that do not reside on the physical file system. Virtual Shell objects are used throughout the Windows Shell.

Refimprove date December 2009 Adaptive routing describes the capability of a system, through which routes are characterized by their destination, to alter the path that the route takes through the system in response to a change in conditions. ref http www net.cs.yale.edu publications XQYZ04.pdf ref The adaptation is intended to allow as many routes as possible to remain valid that is, have destinations that can be reached in response to the change. People using a transport system can display adaptive routing. For example, if a local railway station is closed, people can alight from a train at a different station and use another method, such as a bus, to reach their destination. Another example of adaptive routing can be seen within financial market s. For example, ASOR or Adaptive Smart Order Router developed by Quod Financial , takes routing decisions dynamically and based on real time market events. The term is commonly used in data networking to describe the capability of a network to route around damage, such as loss of a node or a connection between nodes, so long as other path choices are available. There are several protocol computing protocols used to achieve this Routing Information Protocol RIP OSPF IS IS IGRP EIGRP Systems that do not implement adaptive routing are described as using static routing , where routes through a network are described by fixed paths statically . A change, such as the loss of a node, or loss of a connection between nodes, is not compensated for. This means that anything that wishes to take an affected path will either have to wait for the failure to be repaired before restarting its journey, or will have to fail to reach its destination and give up the journey.

In computer networking , source routing allows a sender of a data packet packet to partially or completely specify the Routing route the packet takes through the network. In contrast, in non source routing protocols, router computing router s in the network determine the path based on the packet s destination. Source routing allows easier troubleshooting, improved traceroute , and enables a node to discover all the possible routes to a host. It also allows a source to directly manage network performance by forcing packets to travel over one path to prevent congestion on another. In the Internet Protocol , two IPv4 Header header options are available which are rarely used strict source and record route SSRR and Loose Source Routing loose source and record route LSRR . Because of security concerns, packets marked LSRR are frequently blocked on the Internet. If not blocked, LSRR can allow an attacker to IP address spoofing spoof its address but still successfully receive response packets. ref cite web url http www.microsoft.com technet archive community columns security netdef sourcead.mspx title Source Address Spoofing author Rik Farrow work TechNet publisher Microsoft Corporation ref Policy based routing can also be used to route packets using their source addresses.

Hierarchical routing is method of routing in networks that is based on hierarchical addressing. Background Most Transmission Control Protocol Internet Protocol Internet protocol suite TCP IP routing is based on a two level hierarchical routing in which an IP Network address address is divided into a computer network network portion and a Server computing host portion. Gateways use only the network portion until an IP datagram reaches a Gateway computer networking gateway that can deliver it directly. Additional levels of hierarchical routing are introduced by the addition of subnetworks. Description Hierarchical routing is the procedure of arranging routers in a hierarchical manner. A good example would be to consider a corporate intranet . Most corporate intranets consist of a high speed backbone network . Connected to this backbone are routers which are in turn connected to a particular workgroup. These workgroups occupy a unique local area network LAN . The reason this is a good arrangement is because even though there might be dozens of different workgroups, the span maximum hop count to get from one host to any other host on the network is 2. Even if the workgroups divided their LAN network into smaller partitions, the span could only increase to 4 in this particular example. Considering alternative solutions with every router connected to every other router, or if every router was connected to 2 routers, shows the convenience of hierarchical routing. It decreases the complexity of network topology , increases routing efficiency, and causes much less congestion because of fewer routing advertisements. With hierarchical routing, only core routers connected to the backbone are aware of all routes. Routers that lie within a LAN only know about routes in the LAN. Unrecognized destinations are passed to the default route.

Unreferenced date December 2009 Orphan date February 2009 In connectionless routing , each Packet information technology packet is treated separately, making its way through the computer network network independently. Each individual packet may take different routes through the network depending on the type of routing protocol used and the amount of traffic on the network. As the packets travel along varying routes, they may not necessarily arrive at the designated location in sequence. To overcome this problem, the sending computer will assign a sequence number to each of the packet along with information regarding the message stream to which the packet belongs. The network layer on the receiving computer would then reassemble the packets in the correct sequence prior to passing the packets to the application layer .

Cleanup date May 2011 Deflection routing is a routing strategy for networks based on packet switching which can reduce the need of buffering packets. Every packet has preferred outputs along which it wants to leave the router computing router , and when possible a packet is sent along one of these outputs. However, two or more packets may want to leave along the same output which is referred to as a contention among packets , and then only one of the packets may be sent along the link, while the others are sent along available outputs, even though the other links are not preferred by the packets because, for instance, those links do not yield shortest paths . Depending on the rate of incoming packets and the capacity of the outgoing links, deflection routing can work without any packet buffering . Of course, it is always possible to simply drop packets in a network with a best effort delivery strategy. See also Dynamic Alternative Routing Category Routing ... more details
