Download Programming the Network with Perl by Paul Barry PDF

By Paul Barry

It truly is now not sufficient for modern-day software program engineers so that it will application the pc and debug courses - the trendy programmer must understand how to software the community and debug communications. This ebook indicates you ways, utilizing Perl.

initially created as a device for process directors, the Perl Programming languauge has matured right into a strong, but easy-to-use, general-purpose programming language. commonplace on the net, Perl is the programming language of selection in terms of including dynamic content material to web pages utilizing the typical Gateway Interface (CGI). Its strengths - simplicity, energy and flexibility - make it a good motor vehicle with which to check desktop networking and to application machine networks typically.

In Programming the community with Perl, Paul Barry applies Perl to the research of tradiitonal computing device networking themes. After an introductory instructional to the Perl programming language applicable for the non-Perl programmer, 5 key machine networking themes are tested from the viewpoint of the software program engineer utilizing Perl.

  • Snooping information the construction of a successively extra useful set of Ethernet community Analaysers and cumulates within the improvement of The community Debugger, a device for tracking the site visitors generated by way of either ordinary and custom-built networked functions.
  • Sockets information tips to use Perl to create customized networked functions through programming the TCP/IP shipping protocols (TCP and UDP), utilizing the Client/Server version and the normal Berkeley Socket API.
  • Protocols information simply how effortless it's to software the HTTP (web), SMTP (e-mail), NNTP (news) and TELNET (remote login) protocols with Perl. HTML parsing is usually defined.
  • administration makes use of Perl to application the easy community administration Protocol (SNMP), the cornerstone community administration expertise at the glossy net.
  • cellular brokers is a presentation of 1 of the applied sciences that may be extra to Perl to supply for the advance of customized networked functions that may shipping themselves from community machine to community gadget whereas executing.

each one bankruptcy concludes with a suite of Print and net assets, in addition to urged workouts to help additional learn via the reader.

The linked web site presents Perl hyperlinks, downloadable resource code, presentation fabrics (in PDF format), and directions for becoming a member of the pertnetbook dialogue mailing record.

Download Performance Modeling of Communication Networks with Markov by Jeonghoon Mo PDF

By Jeonghoon Mo

This booklet is an advent to Markov chain modeling with functions to verbal exchange networks. It starts with a basic advent to functionality modeling in bankruptcy 1 the place we introduce diverse functionality versions. We then introduce easy rules of Markov chain modeling: Markov estate, discrete time Markov chain (DTMC) and non-stop time Markov chain (CTMC). We additionally talk about how to define the regular nation distributions from those Markov chains and the way they are often used to compute the approach functionality metric. the answer methodologies contain a stability equation procedure, restricting likelihood procedure, and the uniformization. we attempt to lessen the theoretical facets of the Markov chain in order that the publication is definitely obtainable to readers with no deep mathematical backgrounds. We then introduce how one can advance a Markov chain version with uncomplicated functions: a forwarding process, a mobile approach blocking off, slotted ALOHA, wireless version, and multichannel established LAN version. The examples conceal CTMC, DTMC, birth-death technique and non birth-death technique. We then introduce tougher examples in bankruptcy four, that are concerning instant LAN networks: the Bianchi version and Multi-Channel MAC version with mounted length. those versions are extra complicated than these brought in bankruptcy three simply because they require extra complex thoughts akin to renewal-reward theorem and the queueing community version. We introduce those techniques within the appendix as wanted in order that readers can stick to them without problems. we are hoping that this textbook could be beneficial to scholars, researchers, and community practitioners who are looking to comprehend and use mathematical modeling thoughts. desk of Contents: functionality Modeling / Markov Chain Modeling / constructing Markov Chain functionality types / complicated Markov Chain versions

Download Multiple User Interfaces: Cross-Platform Applications and by Ahmed Seffah, Homa Javahery PDF

By Ahmed Seffah, Homa Javahery

A number of consumer Interfaces permit humans utilizing cellphones, lap tops, table tops, palm tops or PDAs to entry and skim info from their vital server or the net in a coherent and constant approach and to speak successfully with different clients who should be utilizing various units. MUIs supply a number of perspectives of the knowledge in keeping with the equipment used and co-ordinate conversation among the users.Multiple person Interfaces: Engineering and functions Frameworks is the 1st paintings to explain consumer interface layout for cellular and hand held units reminiscent of cell phones. Given the proliferation of books on website design within the overdue '90s, this grants to be the forerunner in a brand new wave of books facing the problems particular to small displays, restricted reminiscence and instant transmission. It additionally bargains with difficulties with regards to multi-user performance and sharing an analogous software over quite a few systems. * deals a entire account of state of the art study * Combines human and technical features together with social interplay, workflow, HCI, & procedure architectures. * presents functional toolkits, directions and event studies * contains contributions from major specialists in any respect the foremost associations - Virginia Tech, Concordia college, Lancaster collage, Ericsson & Intel With any such precise and state of the art technique researchers and builders engaged on person interface layout in businesses production handsets and different moveable units, collage HCI teams and corporations delivering web-based details companies for supply to handheld units will locate this vital.
