Engenharia de Redes e Serviços

A unidade curricular Engenharia de Redes e Serviços (ERS) visa fornecer conhecimento especializado na engenharia de redes e serviços de comunicações, promovendo o conhecimento, capacidades e competências na definição, desenvolvimento e gestão de serviços de rede quer sobre plataformas de comunicação fixas quer móveis. É dada atenção especial a tópicos importantes como a segurança e a gestão de redes, o desenvolvimento e suporte de aplicações e serviços envolvendo conteúdos multimedia.

Coordenação Científica

• Joaquim Macedo
• Bruno Dias
• António Duarte Costa
• Maria João Nicolau

Esta unidade curricular tem a seguinte estrutura básica:

• Segurança em Redes
• Gestão de Redes e Serviços
• Programação Distribuída e de Tempo-Real
• Serviços e Sistemas Multimédia
• Seminários

Education/ERS Web Preferences

The following settings are web preferences of the Education.ERS web. These preferences overwrite the site-level preferences in TWiki.TWikiPreferences and Main.TWikiPreferences, and can be overwritten by user preferences (your personal topic, eg: TWikiGuest in the Main web).

Web Preferences Settings

These settings override the defaults for this web only. See full list of defaults with explanation. Many of the settings below are commented out. Remove the # sign to enable a local customisation.

Natural Skin configuration

• Set SKIN=nat

• Set SKINSTYLE = Plain
• Set STYLEBORDER = thin
• Set STYLEBUTTONS = off
• Set STYLESIDEBAR = left
• Set STYLEVARIATION = none
• Set STYLESEARCHBOX = off

• Set PAGETITLE = Engenharia de Redes e Serviços

• Set NATWEBLOGO = Engenharia de Redes e Serviços

• Set WEBCOPYRIGHT = Copyright © by the contributing authors. Ideas, requests, problems? Send feedback.

• List of topics of the Education/ERS web:
  • #Set WEBTOPICLIST = Changes | Index | Search | Go

• Web-specific background color: (Pick a lighter one of the StandardColors).
  • Set WEBBGCOLOR = #D0D0D0
  • Note: This setting is automatically configured when you create a web

• Image, URL and alternate tooltip text of web's logo.
  Note: Don't add your own local logos to the TWikiLogos topic; create your own logos topic instead.

• Set WEBLOGOURL = WebHome
• Set #WEBLOGOIMG =
• Set WEBLOGOIMG =
• Set WEBLOGOALT = Engenharia de Redes e Serviços

• List this web in the SiteMap. If you want the web listed, then set SITEMAPLIST to on, do not set NOSEARCHALL, and add the "what" and "use to..." description for the site map. Use links that include the name of the web, i.e. Education/ERS.Topic links.
  Note: Unlike other variables, the setting of SITEMAPLIST is not inherited from parent webs. It has to be set in every web that is to be listed in the SiteMap
  
  • Set SITEMAPLIST = on
  • Set SITEMAPWHAT = Engenharia de Redes e Serviços
  • Set SITEMAPUSETO =
  • Note: Above settings are automatically configured when you create a web

• Exclude web from a web="all" search: (Set to on for hidden webs).
  • Set NOSEARCHALL =
  • Note: This setting is automatically configured when you create a web

• Prevent automatic linking of WikiWords and acronyms (if set to on); link WikiWords (if empty); can be overwritten by web preferences:
  • #Set NOAUTOLINK =
  • Note: You can still use the [[...][...]] syntax to link topics if you disabled WikiWord linking. The <noautolink> ... </noautolink> syntax can be used to prevents links within a block of text.

• Default template for new topics for this web:
  • WebTopicEditTemplate? : Default template for new topics in this web. (Site-level is used if topic does not exist)
  • TWiki.WebTopicEditTemplate: Site-level default topic template

• Comma separated list of forms that can be attached to topics in this web. See TWikiForms for more information.
  • Set WEBFORMS =

• Users or groups who are not / are allowed to view / change / rename topics in the Education/ERS web: (See TWikiAccessControl). Remove the # to enable any of these settings. Remember that an empty setting is a valid setting; setting DENYWEBVIEW to nothing means that anyone can view the web.
  • #Set DENYWEBVIEW =
  • #Set ALLOWWEBVIEW =
  • #Set DENYWEBCHANGE =
  • #Set ALLOWWEBCHANGE = PauloCarvalho
  • #Set DENYWEBRENAME =
  • #Set ALLOWWEBRENAME = PauloCarvalho

• Users or groups allowed to change or rename this WebPreferences topic: (e.g., TWikiAdminGroup)
  • #Set ALLOWTOPICCHANGE = PauloCarvalho
  • Set ALLOWTOPICRENAME = PauloCarvalho

• Web preferences that are not allowed to be overridden by user or topic preferences:
  • Set FINALPREFERENCES = NOSEARCHALL, ATTACHFILESIZELIMIT, WIKIWEBMASTER, WEBCOPYRIGHT, WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE, DENYWEBRENAME, ALLOWWEBRENAME

Help on Preferences

• A preference setting is defined by:
  3 or 6 spaces * Set NAME = value
  Example:
  • Set WEBBGCOLOR = #FFFFC0
• A preferences setting can be disabled with a # sign. Remove the # sign to enable a local customisation. Example:
  
  • #Set DENYWEBCHANGE = UnknownUser
• Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
  • When you write variable %WEBBGCOLOR% , it gets expanded to #D0D0D0
• The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
• You can introduce your own preferences variables and use them in your topics and templates.
