IENCE C • •S T S E C Small world for dynamic wireless cyber-physical N O H I N systems S O I V Dissertation L • O S 142 G T Y H • R Industries and consumer markets are today increasingly using G I E L VTT SCIEN CE S H E G services exposed from wireless sensor and actuator networks, A I R H C cyber-physical machine-to-machine systems. The motivation for H the research arises from problems detected in the remote 1 4 2 interaction with embedded devices over dynamic wireless networks in such systems. The selected approach is based on the application of the small- world paradigm to cyber-physical systems. It is here assumed that the concept of small world, "six degrees of separation", can be expanded to also cover communication with wireless embedded devices in cyber-physical systems context. The main contributions are the technical enablers referred to as dynamic communication spaces, dynamic M2M service spaces, configuration and remote use of services, communication overlay, access systems selection, integrated mobility, secure ad hoc networking, situated opportunistic communication, hierarchical networking for small-world networks, and short-cuts for network optimization. The enablers have been evaluated as separate technical methods and means by means of experiments and/or simulations. According to the evaluations, the enablers seem to work well as separate building blocks and that they can be combined to expand the concept of small world to also cover communication with embedded devices. Wireless short-cuts can improve the scalability and efficiency of dynamic wireless networking and weak links are essential in the neighbour discovery process. -

Well Known TCP and UDP Ports Used by Apple Software Products
Well known TCP and UDP ports used by Apple Languages English software products Symptoms Learn more about TCP and UDP ports used by Apple products, such as OS X, OS X Server, Apple Remote Desktop, and iCloud. Many of these are referred to as "well known" industry standard ports. Resolution About this table The Service or Protocol Name column lists services registered with the Internet Assigned Numbers Authority (http://www.iana.org/), except where noted as "unregistered use." The names of Apple products that use these services or protocols appear in the Used By/Additional Information column. The RFC column lists the number of the Request For Comment document that defines the particular service or protocol, which may be used for reference. RFC documents are maintained by RFC Editor (http://www.rfc- editor.org/). If multiple RFCs define a protocol, there may only be one listed here. This article is updated periodically and contains information that is available at time of publication. This document is intended as a quick reference and should not be regarded as comprehensive. Apple products listed in the table are the most commonly used examples, not a comprehensive list. For more information, review the Notes below the table. Tip: Some services may use two or more ports. It is recommend that once you've found an instance of a product in this list, search on the name (Command-F) and then repeat (Command-G) to locate all occurrences of the product. For example, VPN service may use up to four diferent ports: 500, 1701, 1723, and 4500. -

References 30 2 A Review of HTTP Live Streaming Andrew Fecheyr-Lippens 1.Introduction to streaming media In the early 1990s consumer-grade personal computers became powerful enough to display video and playback audio. These early forms of computer media were usually delivered over non-streaming channels, by playing it back from CD-ROMs or by downloading a digital file from a remote web server and saving it to a local hard drive on the end user's computer. -

Chapter 6 - Windows 2000 DNS Page 1 of 65 Windows 2000 Server Chapter 6 - Windows 2000 DNS Microsoft® Windows® 2000 DNS is compliant with the standard Domain Name System (DNS) as described in the Request for Comments (RFC) documents of the Internet Engineering Task Force (IETF). DNS is the de facto naming system for Internet Protocol (IP)–based networks and the naming service that is used to locate computers on the Internet. Because Windows 2000 DNS is RFC- compliant, it interoperates with most of the other DNS server implementations, such as those DNS servers that use the Berkeley Internet Name Domain (BIND) software. This chapter describes the new features and enhancements of Windows 2000 DNS and explains how to set up and configure some of the features. For more information about DNS-related RFC standards that are supported by Windows 2000, see "Introduction to DNS" in this book.
