Data Centre Networks

The data centre (DC) is the place where central compute and storage reside to enable key applications to operate in the organization. The network at these locations is required to provide very high speed connectivity. In the same way, this is the central location for secure ingress into the corporate network and the Internet. Data centre security segmentation is a typical need.

Retis is aware of the challenges required to enable connectivity to different components in this place like standalone or chassis servers, storage controllers or hyper-converged / unified solutions that contain both. In the same way, this applies to all virtualization hypervisors (VMWare and other) and container solutions deployed on top of the compute resources.

Key network resources are also typically integrated into these solutions like load balancers, high capacity next generation firewalls, central Wi-Fi controllers, management, visibility and surveillance nodes and obviously all network devices strictly focused on packet forwarding like switches and routers.

The architecture of the network can be done in a traditional way or also following a “Software Defined” approach (SDN) that paves the road for application micro-segmentation as well as new automation and orchestration solutions.

Retis architects have vast experience dealing with data centres of different sizes. It is also good to mention the new approach to create a hybrid solution with some components in the Cloud and some on premise.  


Campus and Branch Networks

The edge of the network is also a key component to provide access to all end users.

Retis consultants have experience starting from the network foundation all the way to the end user application experience. We know all environmental and cabling requirements and standards (fibre or copper) needed to create a multitier network.

We have deep knowledge about all access, distribution and core switching technologies and industry trends. These can include PoE, multi-gigabit Ethernet, WiFi access points, IoT building systems nodes, QoS, VoIP - PBX, Video, and other collaboration end point requirements. Network access control (NAC) and client zone segmentation are also a typical security requirement included in this part of the network.


Wide Area Corporate networks

A large distributed organization in the same province or state, country or at an international level has a strong business dependency on a WAN.

Retis consultants experienced the challenges involved in deploying various sizes of WAN networks. First we start by being aware of the application constrains like capacity, priority, latency and jitter. If these are not satisfied, several remote business users will be affected.

We know the different connectivity products typically offered by service providers in our area. These can go from MPLS, VPLS, DWDM, dark fibre all the way to simple Internet access circuits. We are also aware and able to integrate VPNs and SD-WAN alternatives that can be used to lower cost and migrate locations away from expensive private circuits to simply use multiple Internet links.

Finally, the architecture is complete by gluing all circuits together and adding the right routing protocols (OSPF/EIGRP/BGP) to provide the right resiliency and availability to meet the organization priorities.


Unified Communications, Voice, Video and Collaboration Networks

It is clear today’s requirement is to transport voice, collaboration data and even video within organizations. This can be either in the same site, campus or building (LAN) or between different sites; these sites can be located in the same city, country or even in a different continent (MAN/WAN).

Retis consultants have the experience to architect these type of networks. A solution design can be created using proven technologies like Video and Voice over IP (VoIP).

PSTN access is also being migrated away from traditional analog or PRI interface types to SIP trunks. Personal DID numbers and long distance become something with no boundaries at a country level.

Organizations benefit by using their existing data network and allowing users using diverse endpoint types (from a home phone, smartphone, tablet, desktop, office phone all the way to large video conferencing rooms) to all experience a similar voice, video and content collaboration experience. 


Customer Contact and Call Centres

Times change and the form by which an organization contacts its customers is also changing. We live in cities that are wide and in constant expansion. At the same time, we must analyze and make efficient use of our time. As time passes, it becomes more and more difficult to establish a face-to-face contact with our customers. Alternatively, we could let our voice, our image or our data, travel instead of our bodies when contacting a customer; let us build a Customer Contact Centre.

Retis consultants have the experience to build customer contact centres. Traditionally, these solutions have used telephony as the typical channel for contacting customers. Typical elements like a VoIP PBX assisted by an Automatic Call Distributor or ACD can now be interfaced with newer solutions or “pieces in the puzzle”. Client server applications, Internet and WWW interfaces, audio response menus contained in IVRs, predictive dialers, email or chat campaigns, integrated messaging solutions (FAX to email to voicemail) can now all be integrated together.

Retis offers consulting services for the creation of traditional telephony call centres as well as enhanced contact centres. In this case, Retis consultants deliver the classic voice traffic architecture required to determine the necessary resources (lines, agents, trunks) to include in the design. As a complex distributed solution, our services cover all aspects of an integrated solution.

As a result, customers expand their sales and support efforts and streamline the flow of information among company's departments and its customers.


Network Security

The questions Retis consultants often ask the customer are: “What is the price of the information exposed to the Internet and also included in the corporate network? How much money and credibility will the company lose if this information is altered, compromised or lost? How many productive hours of your staff will be wasted and at what price (cost of lost business, lost labor)? And finally, how are these events going to affect the final customer perception about the company (loss of customer trust, damage to reputation)? “

With this information in mind, it is easy for a CIO or CFO to calculate the Return of Investment (ROI). Benefits for investing in Network Security are increasingly clear.

Retis offers a series of services to allow customers to keep on being “connected to the world” but in a much safer way.

These services may go from a basic Firewall implementation to more robust security techniques like network segmentation, the creation of Virtual Private Networks (VPN), the installation of Intruder Detection Systems (IDS/IPS), network anti-virus software, deep threat analysis authentication servers, etc.


Wireless networks

With the advent of laptops, smartphones and tablets, users have the expectation to always stay connected. Wi-Fi / WLAN networks have become ubiquitous as organizations are now expected for these to be available.

Architecting a great WLAN is not an easy task. Retis architects know how to create the right radio frequency (RF) design and plan the locations for all access points and the type of antennas to use. All depends on the type of clients, applications and physical space. Then, they define the channel and power for all radios. Next, the logical configuration of different networks (SSIDs) and the security requirements associated to each. Some SSIDs go to a guest portal, some remain hidden and some are used by the organization internally.

A Wi-Fi network is then subject to a final assessment which is followed by adjustments and then full operation with the right surveillance.

We can also include the use of mobility networks (4G, LTE and 5G in the near future) as a WAN alternative to provide resiliency for branch access or simply as the alternative to enable connectivity at odd locations or to meet the timelines of a project.





Retis offers services that can be part of different phases in the life of a network. All previously described technology solutions are used to deliver the following services.


Network Architecture

This is our main service targeted to satisfy the need to build a new network or part of it.

Retis Architecture Methodology

Retis has managed to integrate different ideas and to develop an efficient methodology for network design.

Network Architecture Plan Elements

As a proof of how solid and mature our methodology for network architecture and assessment is, we share the main phases and activities we cover as part of these projects.


·         Gathering organization’s vision, timelines and budget perceived by project stakeholders.

·         Network Design requirements and constrains gathering

o   Technical requirements 

§  Functional: connectivity, capacity, performance, Internet access, dynamic routing and QoS.           

§  Security: security and routing segmentation, encryption and authentication.   

§  Resiliency: WAN and Internet, automatic failover to alternate DC / POP. HA, DR and BCP expectations.     

§  Equipment and circuit’s lifecycle.           

§  Operational requirements: surveillance,   management, visibility, security policy management, event management and backups.

§  Existing and new applications assessment and baseline.

·         Design phase. The network architecture is divided into modules / building blocks. Each block design validates all associated constrains. We then present multiple options that can equally apply. Options include single or multiple vendor products and their associated cost. A matrix presents all options for decision makers to see in one place. Finally the Retis architect suggests one alternative. The decision makers and all stake holders reach agreement and the cycle continues for all other components.

o   Typical network architecture modules / building blocks (DC network used as a reference):

§  DC switching fabric.     

§  Fabric cabling and optics.  

§  Layer 3 and routing design.   

§  Internet, edge networks and DMZ access.

§  Security elements: Network segmentation and firewalls, VPN service, IDS/IPS inspection and other security elements, distributed denial of service (DDoS) solution, etc.

§  Load balancing solution.  

§  Wireless controllers.      

§  Share network services for servers and end users (DNS/DHCP/IPAM).     

§  Network management and surveillance. This includes: configuration management, network device inventory, network surveillance, availability, capacity and environmental management, event management, network flow management, network authentication, network visibility (packet capture and analysis) and out-of -band secure connectivity.

§  LAN-WAN design and integration: Internet access, private circuits and even potential SD-WAN integration.        

·         Prototype phase. If leading edge technology is part of the design, this phase tests its functionality to demonstrate the solution feasibility (prepared in a laboratory). A typical current case is SDN integration.

·         Generation of the bill of materials (BoM) and procurement.

·         Implementation.

o   Pilot section of the network to test the prototype with real servers / users.

o   Final roll-out of other components.

·         Monitoring and evaluation of new network’s performance and stability.

·         Documentation and knowledge transfer.

·         Delivery to client’s operations area.


Existing Networks Assessment, Analysis and Audit

Even if the organization is proud of their network, there is nothing like having a consultant with fresh eyes to validate its operational objectives, cost and functionality. Retis consultants offer an impartial point of view in terms of vendor dependency.

The benefit of the network analysis and audit is to show customers how efficient and cost effective their existing network is.

A series of interviews, information gathering and tests are applied. Tests use various existing or additional tools and equipment to specific local or remote segments in the network. After the analysis Retis delivers a document containing diverse metrics (graphic and numeric) indicating the degree of network efficiency and a series of recommendations to modify the network so it will match the client’s needs.

The purpose of this service is to:

·         Lower operational costs if possible.

·         Allow customers to improve their network functionality without always requiring big investments.

·         Proactively identify and resolve design issues.

·         Increase availability and performance.

·         Establish baselines to measure future improvements or changes.

At the end of a network audit, Retis may offer additional services to redesign and implement the required changes to the network as a consequence of this analysis.


Network Audit Plan Elements

·         Introduction to various key players and subject matter experts – SMEs: Stakeholders, network management and operations teams, other infrastructure important players and application and business personnel to explain priority applications, criticality and flows at all production and administrative locations.

·         Assessment of network documentation: diagrams, standards, locations and topology.

o   WAN inventory: Internet and private circuit list, service providers, cost, contract duration, capacity, QoS and SLAs.

o   LAN inventory: Switches, routers, firewalls, load balancers. Lifecycle and support validation.

·         Technical assessment.

o   Inventory of high level network IP addressing and routing.

o   Network configuration and activity information collection.

o   Traffic analysis - general and detailed (mix of applications and top talkers)

o   Latency and QoS analysis.

o   Equipment Performance Analysis

o   Access to key network elements configuration.

·         Operational cost analysis of existing LAN/WAN elements.

·         Improvement analysis

o   WAN: Circuit capacity changes, topology changes, high level analysis of other service provider options in the market for private and Internet circuits.

o   LAN: Removal, consolidation, virtualization or replacement of different elements.

o   Exploration of new available technologies and high level analysis of total cost of ownership and performance expectations.

·         Conduct infrastructure team meetings.

·         Stakeholder and technical presentations.

·         Final documentation is produced and delivered. Includes diagrams and detailed recommendations organizations can follow.



Retis consultants have a wide experience in training in both professional or academic, national and international areas. It is of great satisfaction for Retis consultants to be able to transmit this knowledge.

Training is usually offered to the customer as a consequence of the conclusion of a complex project or audit. Customer’s engineers receive this benefit and are therefore capable of configuring and administering the new technologies.




About Retis

History and Company Resume

In 1996 the idea was conceived to create a group of consultants entirely focused on the delivery of professional services in the field of computer networks.  The new group led by Enrique Waizel and composed by Mexican consultants then focused on the architecture and auditing of voice and data networks and distributed applications covering all different layers typically present in this kind of environments.

By the end of 1998, in order to create an identity and give to the group more formality Retis was born. Retis means “Networks” in Latin. This confirms the group’s objective. Mexico was the geography first covered.

During 2001 an effort was made to expand the company; a new office is opened in Canada. The new office originally covered Western Canada and potentially the US Pacific Coast.



Retis Mission can be summarized as follows:

To offer competitively superior professional services in the field of voice and data communications and related fields. These services can be offered in different areas of expertise with customer satisfaction being the main priority.
