Timely delivery of blockchain data traffic (frequent and low-speed p2mp)with bounded latency and packet loss is the major requirement for the underlying network, I understand some priority-based strategies in the upper levels could also to some degree achieve this fully or partly at least. The mechanisms designed in detnet (congestion protection/explicit route/service protection) should be the best among the available solutions as I can see. Thanks for your comments.

Reading through the mailing I have read about “retransmission” what means for me that dealing with loss and unbounded latency is part of blockchain technology. Is that correct? If I read it correctly the ultimate goal is to optimize “service delivery delay” to be as minimum as possible. One can achieve this via minimizing loss and delay. That points for me more towards strict priority + strict bandwidth reservation. Please correct me if I have missed something.

The onging process is far from real-time, although real-time or at least as low latency as possible is going to be the dominant requirement as far as the service is concerned. Apart from the application-level process optimization, it also would be greatly helpful if the underlying network provides some deterministic network services to reduce the network-level latency to the minimum. In general, the data & information delivery efficiency (in terms of latency in particular) of blockchain could be critical. The network might support this with detnet servces. Thanks.

To use TSN, each transmitter would require a bandwidth reservation for some specific bandwidth. As an example, let's say that each reservation is for 50kbps. Then, 1. Every transmitter must constraint itself to transmit no more than its contracted 50 kbps. To the extent that it transmits any faster than its contract specifies, the packets in excess of the contract WILL be dropped. 2. The network will never oversubscribe a link. If the network is configured to accept a maximum of 800 kbps on a given physical link, then the network will accept at most 16 reservations that pass through that port. 3. A transmitter whose reservation is rejected cannot get the DetNet service. In other words, reserved bandwidth that is not used by a reserved flow is available to best-effort traffic, but not to other reserved flows. If those conditions are acceptable to this application, then it is suitable to be added to the use cases document. -- Norm -------------------------------------------------------------------------------- From: huang.guangping@zte.com.cn [huang.guangping@zte.com.cn] Sent: Monday, July 10, 2017 7:06 PM To: Norman Finn Cc: maseewal@cisco.com eagros@dolby.com detnet@ietf.org pwetterw@cisco.com Subject: 答复: Re: [Detnet] 答复: Re: 答复: Re: 转发: New Version Notification fordraft-blockchain-as-detnet-use-case-00.txt Hi Norm, In the case of blockchain application p2mp communication, the highly frequent delivery of the data (transactions, records, etc.) is low speed traffic (in the magnitude of 10-100kbts), so the bandwidth shall not be the dominant latency contributor. Ensure the traffic be delivered in a bounded latency, and most important of all to reduce the retransmission (would incur extra latency) with both buffer revservation and PREF, would be quite helpful for the real-time blockchain delivery.

Apart from the application-level process impacting the delivery time, it would be greatly beneficial for the supporting network to treat the blockchain flows with deterministic latency and packet loss guarantees, because its highly frequent point to multi-point transport (inherent in blockchain) in which the wild latency and packet loss from best-effort services contributes significant portion of the service delivery delays. As for specific boundacy of blockchain, the industry has yet to specify and quantify other than expect the network play a role to provide latency and packet loss guarantees. Blockchain extends beyond its original meaning as a technical term to stand for an emerging industry. I agree and am ok if it's called blockchain-based applications. Thanks for your comment.

As far as I can see, the blockchain application is a valid use case for DetNet, and it is different enough from the other use cases in terms of its application that I it would be interesting to include it in the Use Cases draft. Regarding the ask for “Layer 3 Multicast”, my understanding is that this is already implied by the Use Case Common Theme “L2 and L3 Integration”, which says the following: 8.1.4. L2 and L3 Integration A DetNet network is intended to integrate between Layer 2 (bridged) network(s) (e.g. AVB/TSN LAN) and Layer 3 (routed) network(s) (e.g. using IP-based protocols). One example of this is "making AVB/TSN- type deterministic performance available from Layer 3 applications, e.g. using RTP". Is that sufficient, or do we need to add something more specific about L3 multicast? Also, before adding it to the Use Cases draft, I would like to see some technical review input from the list members, since I myself am not an expert in the area of blockchain. Thanks again, Ethan.

Generally speaking, blockchain is both a technical term and a blockchain-based industry, which is spreading into a wide range of industries other than the thriving bitcoin. Blockchain would have to require the supporting network offer deterministic networking service rather than the ongoing best-effort, because of its inherent p2p and frequent multicast working mechanism. Blockchain working process, its current network mechanism and challenges ahead, as well as requirements to detnet will be illustrated in the draft.
