about how network downtime impacts
on MSPs, ISPs and SPs budget.

Network downtime is one of the most expensive issues for MSPs, ISPs and SPs network architectures. It’s unavoidable, systematic and often unpredictable.
The most relevant study conducted by Gartner has demonstrated that network downtime can cost on average up to $9,000 per minute.
Organization size is also a key factor. For Fortune 1,000 companies, network downtime could cost as much as $1 million per hour, according to an IDC survey. And while the typical mid-sized company spends $1 million per year on incidents, large enterprises can spend up to $60 million or more, according to a research report from IHS.

Considering the pure math without taking in consideration generic case studies, also Cloudscale has mathematically demonstrated through a computational algorithm the relationship “network downtime = money loss”.

where

LR is the Lost Revenue
GR is the Gross yearly Revenue
BT is the total Business Time (in minutes)
I is the percentage of revenue impacted by the down time (an online retail business could see 100% impact whereas a sole proprietor insurance company could be 60%)
T is the downtime

Today the effects of a downtime have direct consequences on loss of company revenue.
Wherever is the cause of a network downtime, MSPs, ISPs and SPs have to consider implementing solutions to mitigate or prevent network downtime.

What are the causes of network downtime?

The IS-IS protocol (ISO/IEC 10589:2002 – included in the OSI model) classifies network downtime in six classes:

Level 0 – Network is down
Level 1 – Part of the network is down
Level 2 – Most of the network is down
Level 3 – All of the network is down except for a few isolated systems
Level 4 – Most of the network is down, but some systems are still functioning
Level 5 – All systems are functioning, but there are performance issues

These categories are used to help network administrators understand the extent of the network downtime and to identify the root cause of the problem. By understanding the level of downtime, administrators can prioritize their efforts to restore the network and minimize the impact on users.

What are the most common causes for network downtime at OSI Layers?

1) Faults, errors or discards in network devices (Layer 2)
2) Wrong device configuration changes (Layer 2)
3) Operational human errors and mismanagement of devices (Multiple Layers)
4) Link failure caused due to fiber cable cuts or network congestion (Layer 1-2)
5) Power outages (Layer 1)
6) Server hardware failure (Layer 4)
7) Denial of service (DoS) (Multiple Layers)
8) Distributed denial-of-service (DDoS) (Multiple Layers)
8) Failed software and firmware upgrade or patches (Layer 7)
9) Incompatibility between firmware and hardware device (Layer 7)
10) Other external causes (Multiple Layers)

Fing App (now a Tanaza add-on) has precise and updated real-time and historical lists of network downtime, divided by countries, duration, recurrence, severity, impact. Network administrators can read details about each single network downtime or visualize them in bulk thanks to real-time interactive maps:

The importance of an outage detector system integrated in Tanaza WiFi cloud management

An outage detector system is a network management application that allows the monitoring of network infrastructure’s faults and errors, proposing solutions and tips to fix them and checking the ISP status.

Outage detector systems are fundamental for MSPs, ISPs, and SPs that want to reduce and prevent network issues and avoid the aforementioned costs caused by outages.

The activation of the Fing App in the Tanaza cloud platform allows to identify what network endpoint is hurt by the outage.

Network administrators can visually and fastly identify what types of clients (smartphone, laptop, printer, etc) are connected to the networks thanks to an intuitive list of minimal icons.
Depending on the chosen plan for the add-on, each client will show relevant network information including the status and the classification of connection, type and brand of WiFi client, bandwidth values (download and upload mbps) and OS information (name, version, build).

Fing and Tanaza have combined their core technologies to create the advanced outage WiFi notification system. Thanks to Tanaza + Fing add-on, network administrators can understand if the APs are offline for internet outages around the world, improving their efficiency to inform their customers about recovery times and responsibilities. The add-on is compatible with the main ISPs of each country and allows network managers to compare them by rating and reviews in order to identify in real-time the best solution for internet connection.

Fing App is able to register real-time ISP connection status data, including information about the severity of outage (on a scale of 5 values: minor, moderate, considerable, major, critical), outage duration and recurrence, and geographical impacted areas.

For this reason, Tanaza and Fing add-on is based on an AI-algorithm that operates in a fully automatic way, with no need for manual reporting.

the technical guide to 6GHz
for MSPs, ISPs and SPs.

After only two years after the approval by the FCC regulations and Wi-Fi Alliance (and the progressive approval by the national regulatory authorities in Japan, UE, Latin America) to open up the 6GHz band for unlicensed Wi-Fi broadcasting, the main networking OEMs have already launched the first WiFi6E access points.

This technical guide is quite long, but its length is fundamental to explain all the facets of the revolutionary 6Ghz.

Readers can click on the following links to jump to the interested section.

– Features introduced by the 6GHz band
– Airtime efficiency
– Faster passive/active AP discovery
– What is the difference between 2.4 GHz, 5 GHz, and 6 GHz?
– List of Tanaza Powered Devices and Tanaza Compatible Devices that supports 6GHz

Following the same distribution model of the other bands, each country has enabled the spectrum in different sub-bands.

The FCC has designated four sub-bands for the US territory: U-NII-5, 6, 7, and 8.
The EU Commission, instead, allows network operators to exploit the “U-NII-5 equivalent” part of the band, the lower one: 480 MHz after the 20 MHz guard band.

These data are updated at 08/03/2022

This band frequency includes the orthogonal frequency-division multiple access (OFDMA) feature from cellular technologies, which takes advantage of servicing multiple users on sub-channels transmitted simultaneously. 6GHz supports the native orthogonal frequency division.
OFDMA allows the transmission of significant quantities of data over a single noisy channel. This technique works by splitting a single signal into multiple smaller transmitted signals. OFDMA is perfect for medium-far transmissions, while MU MIMO is more indicated for short-range.

Dynamic random spectrum access and contentionbased protocols require access to multiple channels to maintain acceptable performance.

The best frequency among these depends on inherent hardware features and the real-time radio-frequency environment.

Tanaza cloud management dashboard has specific features with which network engineers can easily manage hundreds or thousands of AP frequencies. They can switch from 2.4GHz to 5 GHz (and soon also to 6GHz thanks to the release of new Tanaza Powered Devices and Tanaza Compatible Devices)

For each AP, MSPs, ISPs, and SPs can select the radio mode, the channel and channel width, and the TX power.

To obtain the maximum signal spread and reduce the propagation loss, the technical conformation of each frequency suggests using the 2.4GHz band for 2.4 GHz radio-supported devices and IoT devices. Older 5Ghz may fall into a ‘legacy’ category and be moved to this band to avoid dragging down the performance of preferred clients in the 5 GHz band.

5 GHz becomes the band for mainstream high-performance devices that are not 6 GHz capable, allowing non-preferred devices to be relegated to 2.4 GHz as above.

The 6 GHz band can be used for the latest, highest-performance devices, almost by definition in the first few years of rollout. It benefits not only from the highest rates available but also from the lack of legacy equipment and lower noise levels in the band.
