| comcast business vpn setup: The Book of Broken Promises Bruce Kushnick, 2015-02-20 Broken Promises is the third book in a trilogy spanning 18 years. Bruce Kushnick, author, senior telecom analyst and industry insider, lays out, in all of the gory details, how America paid over $400 billion to be the first fully fiber optic-based nation yet ended up 27th in the world for high-speed Internet (40th in upload speeds). But this is only a part of this story. With over four million people filing with the FCC to 'Free the Net', one thing is abundantly clear -- customers know something is terribly wrong. Every time you pay your bills you notice that the price of your services keeps going up, you don't have a serious choice for Internet (ISP), broadband or cable service, much less competitors fighting for your business, or maybe you can't even get very fast broadband service. Worse, over the last few years, America's ISPs and cable companies have been rated the most hated companies in America. While Net Neutrality concerns (detailed in Broken Promises) are important, the actions are only a first step and will most likely be tied up in court for the next few years. More importantly, it does not resolve most of the customer issues and there is nothing else on the horizon that will fix what's broken. Broken Promises documents the massive overcharging and failure to properly upgrade the networks, the deceptive billing practices, the harms caused from a lack of competition, the gaming and manipulating of the regulatory system, from the states to the FCC, and exposes the companies' primary strategy: How much can we get away with? There has been little, if any, regard for the customers they serve.--From http://newnetworks.com/bookbrokenpromises/ --(viewed on June 12, 2015). |

| comcast business vpn setup: Switching to VoIP Theodore Wallingford, 2005 More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowersbusinesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O'Reilly's Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you're a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You'lldiscover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed and projects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directoryservices retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium.You'll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices. Switching to VoIP remains vendor-neutral and advocates standards, not brands. Some of the standards explored include: SIP H.323, SCCP, and IAX Voice codecs 802.3af Type of Service, IP precedence, DiffServ, and RSVP 802.1a/b/g WLAN If VoIP has your attention, like so many others, then Switching to VoIP will help you build your own system, install it, and begin making calls. It's the only thing left between you and a modern telecom network. |

| comcast business vpn setup: Coordinating the Internet Fredrik Lindeberg, 2019-12-10 Många självklarheter i vårt digitala samhälle är beroende av Internet för att fungera. Allt från smarta dörrar för hemtjänster, till självscanningsapparaterna på ICA, till nyare bilar, moderna tillverkningsrobotar, telefoner och affärssystem. Den här licentiatavhandlingen reder ut vad Internet är, hur det styrs och vad det har för praktiska konsekvenser. Tidigare forskning finns bland annat inom telekommunikation där Internet liknas vid andra telekommunikationstjänster, så som kabel-TV eller mobiltelefoni, och inom digitalisering både inom management och informationssystem där Internet i det närmaste tas för givet som teknisk infrastruktur. Här tar jag en ansatts där jag förklarar Internet ur ett kombinerat tekniskt och organisatoriskt perspektiv. Studien är principiellt uppdelad i tre delar. Den första delen fokuserar på att begreppsmässigt hitta ett sätt att diskutera Internet utan att essentiella aspekter faller bort, såsom styrningen eller konsekvenser av den tekniska designen. Jag landar i att Internet är både ett tekniskt och ett organisatoriskt fenomen. Tekniskt i bemärkelsen att det handlar om digital paketbaserad kommunikation (dvs att olika paket kan ta olika väg och att det inte finns ett beroende på en viss specifik väg, eller “krets”), vilket kan särskiljas från exempelvis kretskopplad kommunikation (dvs en specific väg från sändare till mottagare) eller rent analog kommunikation. I denna tekniska dimension är Internet förhållandevis likt klassisk telekommunikation såsom kabel-TV och mobiltelefoni, och förlitar sig på best-effort paketbaserad kommunikation. I den andra dimensionen, styrning och organisation, är Internet ett explicit bottom-up fenomen som styrs med andra principer och ideal än klassisk telekommunikation. Till sin utformning är denna minsta möjliga koordination som krävs för att möjliggöra koordinering av de tekniska unika identifierare som behövs för att Internet ska fungera (dvs idag DNS- och BGP-flororna av protokoll för användning av namn och nummer på Internet). Båda dimensionerna, de organisatoriska och tekniska, följer samma designprinciper, och generellt är det meningsfullt att se Internet som en ekologi av aktörer snarare än en organisation i strikt teoretiska termer (exempelvis finns ingen tydlig övergripande strategi, organisationsnummer eller löneutbetalare). Det är dessa designprinciper, som ligger väl i linje med systemarkitektursprinciper för datorsystem, som är orsaken till Internets lager-design där man (generellt) inte ska bry som om vad som händer på andra lager än sitt eget (beskrivet som “separation of concerns” eller i dubbel negation “high cohesion” i texten) samt att ha en minimalistisk ansatts till koordinering och enbart koordinera eller skapa beroenden mellan enheter (både tekniskt och organisatoriskt) när det verkligen behövs (beskrivet som “minimum coordination” eller “low coupling” i texten). Den andra delen fokuserar på hur Internet kan socialt påverkas eller förändras till något annat, eller till något med en annan funktion sett som en styrd organisation. Jag använder begreppet social robusthet, som motpol till teknisk robusthet som i hur man tekniskt kan förstöra Internet, för att diskutera dessa aspekter. Slutsatserna här mynnar ut i att Internets explicita bottom-up och problemsuppdelnings-design gör det märkbart svårt för någon att medvetet påverka Internet för att ändra dess beskaffenhet, och dessutom visar jag att även om man praktiskt lyckas ta över de formellt beslutande råden (exempelvis ICANNs och IETFs styrelser) så finns det inga formella eller praktiska hinder för att bara ignorera dem (dvs switching costs för just ICANN eller IETF är låga, om än tekniskt omständligt med att konfigurera om rötter och routing-tabeller, och betydligt enklare än att gå från IPv4 till IPv6 då utrustning kan behöva ersättas och därmed en betydligt högre switching cost). Med andra ord, det är enklare att byta ut Internets koordinerare än att byta ut Internet mot något som fungerar annorlunda. Däremot är den rådande politiska världsordningen ett hot mot Internet, eftersom den regelstyrda och koordinerade världsordningen inte längre är lika självklar som den varit tidigare. Den tredje och sista studien fokuserar på nätneutralitet, dvs rätten nätverksoperatörer har att fånga värde i andra dimensioner än trafikmängd, som en praktiskt effekt av hur Internet styrs och fungerar. Det primära praktiska bidraget är att nätneutralitet inte får ses som enbart en reglerings och lagstiftningfråga utan det är mer relevant att prata om i termer av nätneutralitet i praktiken. I den bemärkelsen är lagstiftningens vara eller inte vara mindre intressant än praktisk nätneutralitets vara eller inte vara och en tyngdpunktsförskjutning i den offentliga debatten hade fört diskussionen närmare hur Internet fungerar. Sammanfattningsvis ger Internets designprinciper att marknadskrafter, och ej direkt reglering, ska möjliggöra nätneutralitet. För att förtydliga, tanken är att det ska finnas konkurrens inom de flesta nivåer eller lager, och att det är av vikt att det finns konkurrens rakt igenom så att en kundvilja för paketneutralitet på tjänstenivå även påverkar nätägar- och infrastrukturnivå, så att det är användarnas efterfrågan som leder till nätneutralitet (om den användarviljan finns). Dock kan det mycket väl vara så att man som användare inte är intresserad av nätneutralitet och då ska tjänsteleverantörer, nätägare och infrastrukturoperatörer inte heller tvingas vara neutrala genom lagstiftning då det går stick i stäv med designprinciperna. Inte heller ska en grupps vilja kring nätneutralitet påverka andras möjligheter att välja. Genomgående identifierar jag två kolliderande världsbilder, den distribuerade regelstyrda och koordinerade ordningen i sitt perspektiv med sina förkämpar, och den mer integrerande och suveräna världsordningen med sitt perspektiv och sina förkämpar. Rent praktiskt uppfyller Internet en önskad funktion i den tidigare men ej i den senare, då Internet designmässigt är byggt för att tillåta snarare än kontrollera och bestämma. Exempelvis finns det inte inbyggda (tekniska) mekanismer i Internet för att till exempel möjliggöra statlig övervakning eller kontroll av material som finns tillgängligt, och då ligger det mer i statens intresse att ha kontrollerade telekommunikationstjänster, såsom kabel-TV, mobiltelefoni och liknande lösningar där man inte helt enkelt kan lägga på ett “extra lager” för att uppnå kryptering, anonymitet eller tillgång till andra tjänster. I texten använder jag perspektiven tillsammans med teknologi, marknader och byråkrati för att fånga upp dynamiken och strömningarna i Internet-ekologin och jämför med tekniska samhällsförändringar, som exempelvis järnvägsnät, postverk och finansiella marknader. Jag konstaterar att Internet har varit styrt av teknologiskt baserade värderingar, till skillnad från de andra exemplen som i huvudsak har utformats av dynamiken mellan byråkrati och marknad. I denna mån förelår jag att teknologi kan användas som strömning och motperspektiv till den klassiska uppställningen med byråkrati och marknad för att beskriva fenomen i digitaliseringens tidsålder. Avhandlingen sätter även pågående trender i ett bredare perspektiv mot både organisation och teknik, och trycker på vikten av att förstå delarna var för sig och tillsammans för att på ett rikare sätt måla upp helheten. The modern society is to a large extent Internet-dependent. Today we rely on the Internet to handle communication for smart doors, self-scanning convenience stores, connected cars, production robots, telephones and ERP-systems. The purpose of this thesis is to unbundle the Internet, its technology, its coordination, and practical and theoretical consequences. Earlier research has, in telecommunications, focused on the Internet as one of many potential telecommunications services, such as cellphones or cable-TV, and the management and information systems field has by and large treated the Internet as black-boxable infrastructure. This thesis explains the Internet from the combined perspectives of technology and coordination. This text contains three empirical studies. The first is focused on conceptualizing and discussing the Internet in a meaningful way using both technology and coordination frameworks. I unceremoniously conclude that the Internet is both a technological and a coordination phenomenon and neither of these aspects can be ignored. The Internet is technological in that it concerns digital packet switched digital communication (as opposed to circuit switched) or purely analog communications. The technological dimension of the Internet is similar in its constituency to classical telecommunications networks, and has best-effort mechanisms for packet delivery. In the other dimension, coordination, the Internet is an explicit bottom-up phenomenon minimally coordinated (or governed) by other ideals than classical telecommunications networks and systems. At its core this least necessary coordination concerns technical unique identifiers necessary for inter-network communication (in practice today manifested as naming with the DNS protocol suite, and numbering with the BGP protocol suite). Both dimensions follow similar design characteristics; the design of the technical Internet is similar to the design of the coordination of the Internet. These design principles, which are well aligned with software design principles, is the cause of the Internet’s layered design (“separation of concerns” in practice) and minimal view of coordination (the “least coordinated Internet”). In general terms it is fruitful to view the Internet and involved actors as an ecology, rather than one organization or entity in need of governance or control. The second study looks at the social resilience of the Internet. That is, is it possible through social means to change what the Internet is or can be viewed as. I use social resilience as a counterpart to technical resilience, i.e. resilience to technical interference. In essence, the bottom-up and separations of concerns design of the coordination aspect of the Internet minimizes possible influence of actors intent on mission disruption. I also practically show that even a take-over of the central councils have little effect the constituency of the Internet, since these councils are not invested with formal powers of enforcement. This thesis suggests that the cost of switching from ICANN and IETF to another set of organizations is quite low due to the nature of the coordination of the Internet, compared to for example, switching all equipment to IPv6 capable equipment. However, the current political situation is a threat to the current Internet regime, since an international and rule-based world order is no longer on all states’ agendas. The final empirical study focus on the practical and theoretical implications of the Internet on the case of net neutrality. The primary contribution is that de facto and de jure net neutrality differ in practice, and as such de facto net neutrality deserves more attention. Also, I suggest that any regulation, either for or against net neutrality, is problematic, since such regulation would interfere with the inherent coordination mechanisms of the Internet. As such regulation should focus on providing the necessary markets for Internet function given the coordination and design of the Internet. As a net neutrality example, net neutral Internet access options should exist as part of a natural service offering if wanted by customers, not due to direct regulation. Throughout the thesis I identify two colliding world orders, both in terms of digital communication networks and terms of organizing society in general: the rule-based and coordinating order with its champions, and the integrated or sovereign order with its champions. In practical terms, the Internet can be considered a want in the former (the distributed perspective), but not the later (the integrative perspective), since the Internet lacks inherent (technical) controls for surveillance and content control which are necessary in a world order where borders are important. Regardless of if that importance stems from state oversight or intellectual property rights legislation. I use these perspectives together with technology, markets and bureaucracy to catch the dynamics of the Internet ecology. I then compare these dynamics with other technological and societal phenomena, such as railway networks, postal services and financial markets. And conclude that the Internet (as conceptualized in this thesis) can best be explained by technological values, in opposite to the other examples which can best by explained by the dynamics of markets and bureaucracies without any real influence of the values of technology. As such, I suggest that the classical frame of markets and bureaucracy can fruitfully be expanded with technology to better explain the Internet and similar digitization phenomena. This thesis puts current trends in a broader perspective based on technology and organization, where the two perspectives together better can draw the full picture in a rich fashion. |

| comcast business vpn setup: Tcl/Tk in a Nutshell Paul Raines, Jeff Tranter, 1999-03-25 The Tcl language and Tk graphical toolkit are simple and powerful building blocks for custom applications. The Tcl/Tk combination is increasingly popular because it lets you produce sophisticated graphical interfaces with a few easy commands, develop and change scripts quickly, and conveniently tie together existing utilities or programming libraries.One of the attractive features of Tcl/Tk is the wide variety of commands, many offering a wealth of options. Most of the things you'd like to do have been anticipated by the language's creator, John Ousterhout, or one of the developers of Tcl/Tk's many powerful extensions. Thus, you'll find that a command or option probably exists to provide just what you need.And that's why it's valuable to have a quick reference that briefly describes every command and option in the core Tcl/Tk distribution as well as the most popular extensions. Keep this book on your desk as you write scripts, and you'll be able to find almost instantly the particular option you need.Most chapters consist of alphabetical listings. Since Tk and mega-widget packages break down commands by widget, the chapters on these topics are organized by widget along with a section of core commands where appropriate.
