yes, in the hubs.

network monitored for management purpose and provide QoS/QoE to end users, network monitoring is subset or one parameter of network management.

Thanks sir

I would recommend replacing your "Configuration Management" keyword with "Network Management" and change the title of your query accordingly. That will attract the needed experts.

Dear Abdullah Bin Zarshaid,

the use of the SDN concept for the management of LLN networks in the IoT is a currently important topic. In particular, this topic is of great importance for deterministic networking. My list of literature sources can help you.

Hi,

Are you talking about prioritizing Network Management Functions, or ranking industrial products (NMS)?

In the latter case, I am not aware of such studies, but maybe you might be willing having a look at the results of the European Network of Excellence Flamingo focusing on Network and Service Management.

Some good piece of information is available.

The fact to define the complexity of the network from the perspective of the Network Administrator. For me I considered network complexity  as a tool or mechanism to ensure good security system when dealing with device configuration. A complex network architecture and implementation determine how securely you can relied on the  networks infrastructure against internal and external attacks. In most cases security mechanism in a network is not form with a simple rules when one wanted to make them both computationally and un-computationally secured. Hence, sometimes complexity of network can be seen from incapacity of one to understand or provide solution to the challenges faced by his networks and that can be  look from the knowledge based problem and experience  in the field. There so many ways to explore complexity of the network just like what "Rudra" has explained in above.

Hello Nuno,

There are a couple of clarifications that are needed in order to answer your question.

1. As Ryan was asking, do you have access to this network? 

- If you have, please look at the other two questions.

2. Are you allowed to do passive measurements ? In other words are you allowed to  use something like Wireshark ? (many of the enterprise or ISP networks consider passive monitoring a type of attack)

- If you are, you might want to take a look at:  MRTG ( http://oss.oetiker.ch/mrtg/ ) or cacTi ( http://www.cacti.net/ )

3. Are you allowed to do active measurements ? In other words, insert traffic in these networks ? ( *Note: Active measurements are typically used in isolated network environments)

- If you are, you can use tools like: iperf ( https://iperf.fr/ ) or D-ITG ( http://traffic.comics.unina.it/software/ITG/ )

Dear Andreas,

Comments from Matthias are broad and apply all across the mobile internet service providers. I would like to build upon this.

In my research, We deployed several measurement nodes across states of India to evaluate mobile internet service providers (ISP). The data acquisition took place for four consecutive years without a break. We surely found latencies going as high as several minutes, especially in case of TCP. We observed that just before a connection stall, the sender sent a packet which was lost somewhere b/w the cellular base stations. This resulted in an unacked packet due to which all the packets with higher sequence numbers were stalled. After an average delay of 60 seconds, the transmission went under a slow start. This has been further explained "Revisiting the State of Cellular Data Connectivity in India".

This problem was recurring everywhere, we did the measurements. Moreover, we now know this happens due to following two issues:

1. The providers are certainly misconfiguring their infrastructure. E.g. Misconfigured buffers.

2. The base stations  are not strategically located. The data analysis proved that there is a strong correlation b/w poor signal strength and geography of the area.

In the end, the latencies can go very high (I am not saying up to 10 minutes as it depends on the dominant factors which I just mentioned).

You should read the publication I have attached.

Cheers,

Hello Ms Kuhne,

I chanced to come by, or on to your questions and they  intrigued me. At the outset I must admit that I am not a food scientist;   I am an innovator.  I also happen to be an academic who  has been involved in teaching  innovation and technology, innovation and entrepreneurship, or  courses that were variations on those themes. Thus,  your questions were  a source of puzzlement to me. And my response may well be unusual. Your questions which I quote were:

“a) How should a network be structured in order to facilitate innovation and knowledge exchange of (food) SMEs?

b) Which methods could be applied to enrich our understanding of SMEs' needs for innovation and knowledge exchange? “

The first one seem to implicitly suggest that innovation  ( and perhaps knowledge exchange amongst food SMEs) is not occurring to the extent that you would like. If this is indeed the case, there is a tacit acceptance on your part that networks may well  or could help

The second question seems to suggest that we need methods “to enrich our understanding of SMEs’ needs for innovation and knowledge exchange”. Is that correct? Is that what you  are seeking to achieve?

If innovation is not occurring, this is what I would suggest by way of innovation, again  not through the lens of a food scientist but as an innovator of sorts with a general interest in all things innovative. We know for a  fact that  with the long period of drought in  some parts of Africa, there is food shortage. 1) Why not work on developing crops that  do not need much water?  2) Why not develop crops that can grow quickly when the rains come, albeit over just a few days? 3)  Why not develop methods to conserve water that comes  incessantly and unexpectedly? 4) Why not develop crops that can cope with long periods of drought and still produce a healthy yield?   Those obviously apply to Africa. 

But here are a few more: Why not develop crops that  are pest resistant? Why not develop crops that are not affected by the use of pesticide, and  if  used, do not affect those who consume such food? – I assume that food treated with pesticides may have undesirable effects on humans. Please correct me if I am wrong.

Moving away from Africa to  the rich West, I notice that many food items  being sold in our supermarkets  contain all kinds of preservatives such as, for instance, nitrites and other chemicals , including phosphoric acid, alcohol  supposedly used to preserve them, to enhance taste like MSG,  to raise sweetness levels like additive sugar, aspartame, stevia, and  all those additive substances that run the gamut from A-numbers to Z-numbers  including E-numbers. They may extend shelf-life and endow the food with  all sorts of desirable characteristics. Personally speaking, aspartame and stevia cause a bad taste in my mouth and  even nausea.  Is it not possible to  come up with some innovative processes that do not require the use of such  factory-produced chemicals, or synthetic chemicals to act as shelf-life extenders or as taste enhancers or as appearance modifiers ( colouring agents)  so that  they look fresh, appetizing, etc? 

Again, putting on my technology hat, why not develop some form of technology that shows how much longer the food can be consumed, once the sell-by, eat-by dates have actually been reached.  In that suggestion, I can see that food  suppliers, the last in the supply chain,  may not be happy as it might be inimical to their financial interests. Nonetheless, in that  way, we will be able to reduce food wastage. There are a whole range of social actions, often innovative,  that can reduce food waste, I am certain of that. That said, would supermarkets and their suppliers or all parties in the food supply chain be happy to  help?

Coming to your question b) which I take at face value, I am wondering if SME’s still do not understand the need for innovation.  As for knowledge exchange, a Master’s degree student of mine studied  the effects on innovation of  SME’s participating in EU-funded consortia, and the results were not always beneficial to the SMEs when consortia members also included larger parties. Coming to methods, I am at loss to understand what you are driving at. Perhaps you meant something else but articulated in a  manner that resulted in a misinterpretation, particularly by this present writer.  Do feel free to contact me here  or preferably by email to discuss any statements I have made that do not resonate with you. I am of course willing to help you from a  technologist’s viewpoint, should you so desire. I do know something about networks.

My own experience, finally,  is that knowledge-sharing is unlikely to occur between distant actors in the same company; perhaps in other industries -- I worked in the computer industry - it may happen. But, when I was able to bring them  together by inviting them  them  to come to the place I was located (in The Netherlands), with of course my manager's blessing and approval, there was a free flow of information, and yes, knowledge exchange of a a high quality. And this exchange continued when they went back to the UK, USA, Israel,  Italy, Germany, France, etc, or wherever they came from..

I could go on, but shall  go for that period or full stop right now.

Best wishes.
