Project: To define, design, and implement a comprehensive network administration access control system for the DFAIT worldwide network between Ottawa and Embassies worldwide.
Service: Used data normalization to define a login control scheme based on security clearances with access to worldwide devices centrally controlled, restricted and monitored. Verified operation on a locally configured test system prior to worldwide rollout. Completed a total TACACS system upgrade without disruption or compromise of the secure login system
Project: To define the technical requirements for the integration of communications networks between Ottawa HQ, Area Control Centres, Flight Service Stations, and Navigational aids.
Service: Define network configuration, integration objectives, and performance requirements for multiple existing and planned networks and services.
Project: To define the technical requirements for WAN test equipment for the international communications network between Ottawa HQ and Canadian embassies worldwide.
Service: Define test requirements, test equipment specifications, rfp
documents, prepare for bid evaluation and provide procurement assistance.
Project: To design and develop a secure local and wide area network to connect remote users to their office LAN and to connect branch office LANs to the HQ LAN using the public Internet.
Service:
Prime resource for all matters related to secure Wide Area Networking.
Open-source Linux applications (samba, ipsec, and pptpd) were employed to
provide a seamless end-to-end Virtual Private Network as a service feature for
the Newlix SmartRouter. Final deliverables included an auto-configuring firewall
with port and address forwarding, windows/unix interworking for MS Networks,
support for MS VPN, encrypted LAN-LAN connectivity via the public internet, and
web-based configuration tools.
Project: To define a systematic upgrade plan for the Transport Canada national data network provided by GTIS, including equipment selection, cost and project schedule.
Service: Examined the existing national network, reviewed service
requirements and identified upgrade options. The proposed upgrade plan provided
a detailed schedule, and cost projection for the installation of 30 cisco 2600
series routers at various locations across Canada.
Project: To define how Virtual Private Network (VPN) capability could be added to the Newlix Office Server using FreeSWAN, MS PPTP and Samba for linux network servers interworking with Windows and UNIX local and remote clients.
Service: Identified the configuration parameters and options
for the use of Linux FreeSWAN to set up a secure VPN between multiple Private
IP address sub-nets over an Internet connection. Installed and tested a
demonstration system to confirm encryption, implemented and verified MS
browsing capability over the full VPN with multiple subnets and multiple
workgroups. Identified samba limitations for WAN browsing, and defined the VPN configuration options for use in a GUI configuration utility.
Project: To define the service level expectations for an international, integrated voice and data network that interconnects 85 countries for communication between Ottawa and Canadian Embassies around the world. The service level expectations addressed network performance and operational procedures.
Service: The service level expectations are an integral part
of the procurement process for new service contracts. The Service Level
Agreements provide a clear statement of expected performance for both system
users and service providers.
Project: To design and install a BBS that can be used to collect and distribute information and files to various Canadian Forces bases across Canada. The BBS will reside on a local LAN in NDHQ and will be used to collect monthly base statistics and various reports as required.
Service: This system was made operational in May of '96 and eliminated
the need to transfer data files via postal services. Improved delivery
times and inter-base communications were achieved.
Project: To determine user requirements and preliminary network planning for a telemedicine network in rural Chile for the Ministry of Health and Ministry of Telecommunications and Transportation in Chile. Co-Sponsored with the ITU as part of the Beunos Aires Action plan for improved telecommunication services in rural areas (Programme 9).
Service: Established user requirements, preliminary system design,
budget and schedule for a multimedia telemedicine pilot project in the
Coquimbo region of Chile (Region IV) between a total of 6 hospitals. The
proposed network provided the capability for multimedia wideband teleconferencing
and diagnostics as well as narrowband (64 kbs) and voiceband telemedicine
sessions from 4 rural hospitals and a mobile clinic to two larger hospitals
located within the region.
Project: Install and commission a Automated Building Control system control terminal at a remote location on a dedicated TCP/IP LAN using dial-up routing for event notifications, alarms and control commands.
Service: Analysed the network addressing and router installation
requirements and prepared the installation plan and performed the installation
of the Telebit TCP/IP routers. Standardized approach to this configuration
was documented for similar installations at numerous other locations controlled
by similar systems for Public Works Canada.
Project: To define the potential services that could be provided on a mesh connected, ATM based, European VSAT system and to identify the Layer 1 and 2 interfaces that could be encountered for those services. These interfaces would form the basis of the VSAT system design.
Service: Compiled a comprehensive list of private and public
services that are used in Europe and identified that the 85% of all present
interfaces on private networks include SNA, DNA, and ISO based standards.
Report concluded that some provision for hierarchical services, especially
interactive applications, should be included in the design criteria.
Project: To Provide Technical Engineering and Project Management Services for the Technical Services Branch of Transport Canada - Aviation. Preparation of the Technical Specification, Project Schedule, RFP to Industry, and Cost Benefit Analysis for the Interfacility Satellite Telecommunication Network (ISTN).
Service: ISTN system design optimized for requirements of Transport
Canada and for minimal recurring costs. Recommended the use of DAMA for
the proposed network. Economic analysis of the proposed network completed
and draft technical specification and project schedule completed.
Project: To evaluate satellite communications options for the collection of seismographic data from more than 100 remote stations across Canada to Vancouver and Ottawa.
Service: Technology options were identified and an economic evaluation
of the alternatives was completed. The results and the recommendations
were presented in a report and presentation. The resulting Network was
based on the use of the X.25 protocol, modified to adapt to the large volumes
of traffic generated during seismic events.
Project: To examine the applicability of Local Area Network (LAN) topology to the Telecom Canada telecommunications network, and to examine and compare the relative merits of ring, bus and star topologies.
Service: The services that would be provided by future networks were identified and defined. Based on the definition of these services, the characteristics of the required networks were examined and compared to existing LAN standards for ethernet and token ring and the topologies of existing networks. Recommendations for the future development of the Telecom Canada network were formulated and a report and presentation were prepared and delivered to Stentor members.
