The UOC Network. Descriptive Layer. Mirador

Introduction

The UOC network is currently segmented into 6 sub-networks differentiated by their functions and the services offered, and by the different security levels required. Each sub-network has its own back-up system.

The following diagram shows the division of the UOC Network into the 7 sub-networks. By clicking on each one, you will be shown the different characteristics they have and the services they offer.

The diagram also shows the 7x24 service, whose aim is to monitor the communications and services offered by the University 7 days a week, 24 hours a day.

Diagram of the UOC Network

Internal Network

This is the network to which all UOC staff workpoint PCs are connected, as well as the printers and file servers* and printer servers*.

From the physical point of view, the internal network includes the following facilities:

		Tibidabo I,II,III
		Diputació
		Drassanes
		World Trade Center
		Support Centres

And it has the following resources:

		File and printer servers (Windows 2000)
		Work point PCs (Windows 98) and peripherals (scanners, readers, CDs...)
		Telework service (Web access via CITRIX tool and Terminal Server)

Resources accessible to the user from the internal network (UOC staff):

Workpoint PC and printer, and departmental scanners

Base software (Windows 98, Office 2000, Web browsers, McAfee anti-virus, Outlook)

Disk spaces

	M User's own unit
	N Unit shared by areas
	G Unit shared by faculty or operating group
	P Unit shared by everyone

Telework service through which the user may obtain access to these disk units via Web (connection by means of UOCNet)

Workpoint support service:

This is a service given to all UOC staff in a centralised manner. The service offers the following functions:

		Maintenance of users access to the different disk spaces.
		PC, printer and peripheral maintenance and incident solution.
		Base software maintenance and incident solution.
		Daily back-up copies of users' data. Information restoration on request by users. These copies do not, in any way, include the hard disk* of the users' PCs and, consequently, it is strongly advised not to save important information on the hard disk, as it would not be possible to retrieve it.
		Laptop loan service.
		Computer in the meeting room.

Notifications of incidents by users of the internal network are made by a management application.

Campus Network

This is the network to which the servers providing the intranet and the extranet services offered by the University are connected.

The services are the following:

		Educational Intranet
		Portal
		Name server
		Internet mail server
		Distribution lists server (lists of users to whom a user can send messages)

The Educational Intranet service is made up of the following elements:

		Servers with identical configuration which work as web server* and distribute the workload among themselves.
		Database server* which contains the dabatase of the Educational Intranet, where users, profiles, preferences, assignations and privileges are defined. It has an historical record of messaging, connections, sessions, and actions relating to the Educational Intranet.
		Disk server containing all the messages, Web documents, didactic materials, and any other content which may be accessible from the Educational Intranet.

The UOC portal is made up of three Web servers with identical configuration which distribute the workload among themselves.

The Internet mail server* centralises both incoming and outgoing mail. It also has the role of being the UOC's primary dominions server*.

There is another mail server whose function is to route messages sent from the UOC, but not through the Educational Intranet. In addition, it carries out the distribution lists service.

Others Network

This is where the servers providing the intranet and the Internet service are connected. These servers require a less stringent security level, or contain applications developed by third parties.

The services that should be singled out here are:

		Internet applications server (the portal's part in which information is not of a fixed type, but rather is looked for at the time of presenting the Web page).
		The Virtual Library service, which is made up of a database server and a Web server.
		Automatic translation service (automatic translation system by SAIL-LABS).
		Server containing applications from websites depending on the portal.
		POP* service server, BSCW (a public tool for group work online), and initiatives or third party websites.

Management Network

This is where the management application servers are connected. It is the network under the greatest degree of protection, given the more confidential nature of the data with which work is done.

The services which should be singled out here are:

		Telematic academic management server.
		Continuing education academic management server.
		Finance management server.
		Human resources management server.
		Server of small management applications.
		Server of pre-exploitation of management applications, and Data Manager.

Development Network

The servers where in the new developments of the University's applications are carried out are connected to this particular network.

The following are the servers:

		Servers for the development of the Educational Intranet (one for the new versions and another for the maintenance of current versions).
		Servers for the development of the management applications.
		Servers for the Idea-Solutions product.
		Servers for systems development and tests.

Lab Network

This is the network to which the servers devoted to teaching or experimental practice or tests are connected.

The following are the most notable services:

		Laboratory for the faculties
		Computing, communications and systems practices and tests.
		Applications used by the teaching staff.

Contributing Staff Network

This is the network to which the servers devoted to contributing staff are connected through a switch.
