Figure 1. Outlining dissemination based on country reports on census activities

User groups are dimensioned the traditional way, user needs relate to census information, primary data are obtained through censuses and surveys and, finally, contents and media are linked together. Any dissemination strategy could then be considered as a realization of a subset of users, needs, contents and media, and with the time dimension added.

If the national statistics office considers its web site as the primary target for disseminating activities, as is the case in many countries, users will naturally be categorized in accordance with what has been discussed earlier in chapter 2.1.

1.3.1        Conventional methods

We will not elaborate on conventional methods for disseminating statistical information since this is outside the scope of this paper. It should be mentioned though that most national statistics offices have in the past installed printing offices to provide for printed output, e.g., reports, press releases, yearbooks and so forth, with often high costs for acquisition and maintenance of equipment.

Today the needs for in-house publishing capacity are diminishing since there are dissemination alternatives now available that were not available in the past. Outsourcing printing when called for has also often proved to be cost-effective.

Other ways of disseminating information have been and still are workshops, seminars and conferences as well as through regional and interregional projects.

1.3.2        Using electronic media

Electronic media have been a first choice for dissemination for a number of years. We could say that this was becoming a true alternative with the introduction of personal computers and networking, even if data had been transferred via magnetic tape between mainframe installations since the 1950s.

Exchanging data on floppies (5 1/4 “, 3 ½ “) and in the most popular PC formats became common during the 1980s. In 1989 a process was developed with which a CD could be directly written by means of a laser beam. The way for the self-creation of CDs was opened. The CD is an ideal medium for distribution of informationof any kind (text, images, sound, data and programs). Equipment for burning CD-ROMs is becoming more and more inexpensive and this method is therefore within reach even for national statistics offices on a very low budget, as well as for customers. Along with relatively low production costs, it provides high memory capacity with direct access and a long lifespan, and is still without competition, even when you only have low production numbers. (For this reason, a majority of all PCs today are already equipped with a CD-ROM drive).

Thus CDs are frequently used for dissemination of statistics since not only can (compressed) data be stored but also retrieval applications, e.g., for tabulation, drill-down analysis and GIS.

1.3.3        Internet: a mix of both?

In the mid-1990s national statistical agencies started to create their first web sites. In the beginning, and with the still undeveloped software available, the ambition was often limited to “being noticed” and this was accomplished through static HTML pages organized in strict hierarchical navigations structures. Pages were often arbitrarily updated except for statistics that were published on a regular basis, such as price indices or short-term business indicators.

One common characteristic was that the information provided on the web site was primarily what had been decided by the producers. The web site was not user-driven in the first place. The reasons behind this were often scarce staff resources and a “wait-and-see” view on the new technique.

With the unprecedented growth of the Internet during the last half-decade it has become obvious that it will be the main channel for dissemination for any statistical agency. The Internet will encompass both the conventional methods and the new ones and will change the strategies of dissemination in a substantial way[14].

1.4         Choosing the Internet as the main platform for disseminating statistics

1.4.1        Deciding on an Internet policy

1.4.1.1       What should be part of an Internet Policy?

It must be remembered that establishing and maintaining a web site as the main dissemination platform for a statistical agency will be a long-term undertaking. It is therefore important that an Internet Policy be outlined well in advance of implementing any kind of web infrastructure.

First, we refer to chapter 3.1 where the dissemination strategy is discussed. The answers to questions A (on contents) and C (on interventions and assumptions) will form the cornerstone of the agency’s Internet policy.

In the next step security issues should be addressed. You should not go for web-site hosting prior to a thorough security assessment, since this will decide on, e.g., if the hosting should be outsourced with an ISP (Internet service provider) or done in-house and what security layers should be implemented in order to secure your data.

Following these steps a plan for implementing the web site should be designed. It will now be decided what resources will be needed, how funds should be provided and so forth.

Furthermore, you must decide on how the web-site support should be organized and how staff training should be done.

Finally, production rules must be set wherein updating, upgrading and maintenance are covered.

1.4.1.2       A dissemination strategy: the case of Statistics Sweden in brief

At the end of 1999 a board decision was taken, stating that from 1 April 2000

q       All official statistics produced under the responsibility of Statistics Sweden should be stored at the macrolevel in Sweden’s Statistical Databases. These statistics should then be made available to the public. One of the information channels for this purpose should be the Statistics Sweden web site;

q       All official statistics under the responsibility of Statistics Sweden and printed in Statistiska Meddelanden (a series of reports) should be available on the web site. They should be standardized by the use of templates and print-on-demand should be offered (through download over the web);

q       All other press releases and a set of the most wanted statistics should also be published on the web site by subject matter area/product in a standardized form; and

q       Under conditions outlined above, official statistics may also be disseminated in publications and yearbooks.

Statistics Sweden’s Internet Policy sets out to achieve these goals by maintaining a dynamic web site and engaging staff at all organizational levels in keeping the site up to date. Strong measures have been taken in order to secure the in-house environment and the statistical databases. Extensive training schemes have been introduced and the agency applies mainstream technology and methods. See also chapter 3.2.3.4.

1.4.1.3       Contents

What should be published on the web site is first and foremost an issue for the top-level management of the national statistics office even if, e.g., the subject-matter departments will be the executing units. It must also reside with the leaders to decide on data integrity, security matters related to data transfer and what rules to be followed while authorizing the site.

1.4.1.4       Infrastructure

The infrastructure for the web site is to a great extent dependent on what your ambitions are. In a modest situation you might well be satisfied by outsourcing everything with an ISP, retaining control only over updating the web site remotely. This is not uncommon for small agencies that cannot afford either the equipment (server, firewall) or the backup and 24-hour availability. In any case, before starting to establish a complete in-house environment for your web site you should always make a cost-benefit analysis not excluding such important things like the needs of redundancy (e.g., backup servers) and staff competence.

There are two hardware architectures:

Figure 1-1 Centralized architecture

Figure 1-2 Open extended architecture

The AR161FW-P-M5, AR169-P-M9, AR169W-P-M9 and AR169RW-P-M9 use the open extended architecture, and other models use the centralized architecture.

The multi-core CPU_2 used as the open platform that has customers' applications developed and provides audio, video, and IoT interfaces. The multi-core CPU_2 of the AR161FW-P-M5 is the ARM CPU running Android OS and supports APK application integration. The multi-core CPU_2 of the AR169-P-M9, AR169W-P-M9 and AR169RW-P-M9 uses X86 architecture and support VM deployment. It can be configured with more memory high-capacity hard disk.

The multi-core CPU_1 and CPU_2 are connected and communicate through the 1000M Ethernet link.

The software architecture of the open platform is unified.

Figure 1-3 Software architecture of the AR open platform

There are two systems: Versatile Routing Platform (VRP) GW system and host Linux OS. The two systems communicate through the Ethernet. The VRP GW system runs in the same Linux OS.

The two systems provide different functions:

1. The VRP GW system manages all network interfaces including Wi-Fi, 3G, and Ethernet interfaces. With capabilities including routing, security, AAA, VPN, multi-core forwarding of the VRP protocol stack, the VRP provides secure and high-performance network channels with various functions.
2. The Linux or Android open platform manages multimedia interfaces (HDMI/AUDIO/BT/GPS) and storage devices, and provides support for open source applications of customers.

From the perspective of network communication, the open platform is a phone or server, and the VRP GW is a router gateway. That is, there are two devices logically. The Linux or Android open platform and applications communicate with external devices through the VRP GW system.

For the extended hardware architecture, the multi-core CPU has no VRP GW system. It provides only the Linux or Android open platform and connects to the VRP GW system of CPU_1 through a physical Ethernet link. For the centralized hardware architecture, the two systems are connected through a virtual Ethernet link.

For the extended hardware architecture, two systems can be enabled in CPU_1. That is, two open platforms connect to the VRP GW system. However, resources in CPU_1 are limited. Generally, customers' or open source applications are deployed in CPU_2.

The host Linux OS and VRP GW system share device resources such as the CPU, memory, and flash memory.
