Re: [tcmtf] Answers to possible questions in the BOF

In the space of "more ideas" ...

Internet of Things devices are likely to send a lot of little packets, infrequently.  Some of those things will have time-sensitive information - but a whole lot of those things will send information that is not very time sensitive. For example, consider the sensor reporting the present temperature inside my home  freezer where even 500ms or more delay is acceptable.

With many IoT devices, it can be helpful to aggregate those small not-too-delay-sensitive packets.

Question 4: Is TCM-TF interesting for the Industry? Should the IETF standardize this?

Answer:

1) TCM-TF intends to update RFC4170, which optimizes RTP VoIP traffic. So if RFC4170 was interesting, why not updating it?

2) TCM-TF can be useful in order to save bandwidth in many cases:

- Aggregation network of *network operators*: We are saving bandwidth by optimizing and putting together traffic flows. Is this interesting for a network operator? What about overprovisioning? The idea is that there are places and moments in which a number of flows based on small packets are in the same place and at the same moment. Then, TCM-TF can be applied in order to provide flexibility. We are not optimizing the overall Internet traffic, we are optimizing specific flows with very tight delay requirements, which network operators have to take care of in a special way.

- *End to end* optimization: Nowadays, many appliances are used to connect remote offices of the same company (creating a VPN). So if a tunnel exists, why not optimizing this traffic when possible? We would save bandwidth in the access network, where it can be scarce.

- Wireless and satellite scenarios.


Any other thoughts? Any other scenarios in mind? Potential beneficiaries?

Asunto: [tcmtf] Answers to possible questions in the BOF

I would like to start a thread about possible questions people may ask in the BOF. Obviously, we also need answers, so we should cooperate.

This is different from the "questions to ask in the BOF". This will be discussed separately.

Thanks!
