Definitions
- TITLE Control of the transmission of at least one content from supplier equipment to an ingestion node.
- the field of the invention is that of “quasi-live” data transfer, that is to say with a very short delay, of the order of a few seconds to about ten seconds between the acquisition of the content and viewing it on third-party equipment, or streaming content. More specifically, the invention relates to the field of transferring content from an access device to an ingestion node of a content distribution network with a view to broadcasting the content thus transferred.
- terminals such as cell phones or other mobile terminals
- CDN Content Delivery Network in English
- These terminals are called content provider terminals and can be user terminals generally used to receive, view, listen to content in other circumstances.
- content servers managed by a content provider, transmit content to ingest nodes, or CDN servers belonging to a CDN content distribution network, in accordance with supply contracts and delivery of pre-established content in which there is notably information relating to the data transmission rate, transmission quality parameters as well as information relating to the volume of data to be transmitted by the content provider to the ingest node.
- Such architectures based on the existence of a signed contract between the content provider and an operator of a CDN content distribution network, are not suitable for the distribution of content, and dynamically by terminals whose users have not, a priori, signed content supply and delivery contracts with the operator of a CDN content distribution network to which the ingest node belongs.
- the equipment providing the content i.e. the camera or the mobile terminal, as content source, is configured in such a way as to transmit data encoded with the highest resolution that this provider equipment is capable of transmitting.
- a drawback associated with these uplink content transmission techniques lies in the fact that the provider equipment does not always know the bit rate available for the uplink established with the ingest node, that is to say the node responsible for recording the content elements (packets, images, GoP, chunk, etc.) transmitted by the supplier equipment and distributing them to user terminals or to one or more other nodes for ingesting or distributing the CDN content delivery network.
- the provider equipment may find itself in a situation where it provides content at a lower rate and quality than the uplink could actually handle.
- the supplier equipment could also find itself in a situation where it transmits content at too high a rate, which can cause data loss during transmission.
- the supplier equipment may find itself in a situation where it supplies content containing gaps (“freeze”) or degraded portions of the content (“blockiness”) and degraded sound.
- the invention meets this need by proposing a method for controlling the transmission of at least one content from a supplier equipment to an ingestion node of a content delivery network.
- Such a method for controlling the transmission of at least one content is particular in that it comprises the following steps implemented by control equipment:
- a content delivery network operator wishes to obtain rewards, such as payments or services performed on its behalf by the supplier equipment, in return for the ingestion of content through an uplink, it must ensure that the content distribution network it operates is capable of satisfying the transmission conditions required by the user of the supplier equipment at the origin of the transmission and conforms to the type of content to be broadcast.
- the user who originally ingested the content is offered more certainty as to the quality of the content that will be broadcast by an equipment of the content delivery network since the quality of the transmission is guaranteed .
- the conditional reward relates to the transaction of a given content and a given supplier equipment.
- the transmission of new content by the same supplier equipment or the transmission of the same content by another supplier equipment triggers the creation of a new conditional reward associated with new expected telemetry data values.
- the telemetry data being directly linked to the quality of the transmission of the content, they constitute the data of choice for determining whether the conditions for triggering the payment transaction are satisfied.
- the reward can be graduated. Indeed, if only part of the negotiated transmission conditions is fulfilled, the reward can be allocated but this corresponds to a lesser consideration since the expected service has not been rendered. Thus, by way of example, if the reward is an amount to be paid for the service rendered, the amount may be revised downwards since all the transmission conditions could not be complied with.
- the latter comprises a prior step of negotiation between said control equipment and the supplier equipment during which said one value of at least least one expected telemetry data is determined.
- the content distribution network transmits transmission offers to the supplier equipment such as tariffs associated with transmission conditions in terms of speed, transmission duration, certain services that the equipment supplier could supply, etc. so that the user of the supplier equipment can select an offer that suits him with regard to the transmission constraints related to the nature of the content to be transmitted and the location of the supplier equipment at the time of transmission. Indeed, the location of the supplier equipment, outdoors or indoors for example, can have an impact on the quality of the transmission. It is then possible to offer visibility to the user on the conditions of transmission of his content.
- control equipment and the supplier equipment also exchange data relating to the type of reward for the implementation of said reward relating to the transmission of said content.
- the validity of the reward takes place immediately and transparently for the user of the supplier equipment.
- the data exchanged during the negotiation step can be included in the data packets constituting the content, taking advantage in particular of the numerous “padding” packets present in the QUIC type streams.
- the reward can be of cyclic type, as described in the document published at https://interledger.org/rfcs/0019-glossarv/#cyclic-transaction, in order to avoid repetitions and to resist packet loss , a cyclical reward applying to other data packets than the one which carried the data relating to the reward.
- the verification of the negotiated transmission condition(s) triggering the reward is based on obtaining by calculation from the actual and expected telemetry data of the same pre-image, described in the document published at the following address https:/ /interledger.org/rfcs/0019-glossary/#conditional-transfer, than the pre-image obtained by a hash of the negotiated transmission condition(s).
- PoT proof of passage
- intermediate nodes as specified in the referenced document https://tools.ietf.org/html/draft-ietf-sfc-proof -of-transit-01#section-3.2.1 further comprising the insertion into data packets of information relating to a reward whose triggering is conditional on the verification of proof of passage triggering the validity of the reward .
- a simple verification condition is the reception by the ingestion node of the same pre-image of a constant of a Lagrange polynomial configured during the negotiation step. The size of the pre-image can be reduced here.
- said at least one telemetry datum belongs to a group comprising among others:
- the identifier can advantageously include the identifier of an operator ensuring the management of the intermediate node
- this quality of service being able, according to an example, to be represented by a qualitative indication of the processing of the packet during its routing towards the ingestion node,
- said comparison step consists in determine a wander delay, and when a value of the wander delay is less than the threshold negotiated between the supplier equipment and the control equipment, the effective transit delay and the expected transit delay correspond.
- said comparison step consists in determining a difference between a effective transmission schedule of said at least one data packet constituting said content, and an expected transmission schedule of said at least one data packet, and when the difference is less than a threshold negotiated between the supplier equipment and the control equipment , the actual transmission schedule and the expected transmission schedule match.
- said comparison step consists in verifying the presence of at least one datum introduced into said content by said at least one intermediate node and comprising the identifier of said at least one intermediate node.

- the general principle of the solution proposes, in order to improve the transmission of "quasi-live” content, that is to say with a very short delay, of the order of a few seconds to about ten seconds between the acquisition of the content and its viewing on third-party equipment, or of “streaming” content, from equipment supplying the content to an ingestion node of a content delivery network, or ingestion of the content, from condition a reward, such as for example a payment, for the service rendered, that is to say the ingestion of the content by the ingestion node, to the respect of certain transmission conditions.
- the provision of service is not rewarded.
- Such a reward can be made for the benefit of one or more entities such as a management entity of the content distribution network CDN, a content provider entity, an operator of a communications network, etc.
- the [fig. 1] schematically represents an example of a system in which the methods which are the subject of the present invention are implemented.
- the system 1 thus represented comprises at least one user equipment, called provider equipment 10, such as a smartphone, a camera, a tablet, etc.
- provider equipment 10 acquires content, such as a video promoting a product or a sporting or cultural event, which the user of the supplier equipment 10 wishes to broadcast to a large number of people.
- the supplier equipment 10 transmits the content to an ingestion node 11 of a CDN content distribution network.
- the content Once the content has been ingested by the ingest node 11, it is prepared, possibly stored or even adapted in a cache server of the content delivery network CDN, and broadcast to other user equipment such as smartphones, stream decoders video or Set-Top-Boxes, personal computers, connected televisions, etc.
- the content delivery network CDN also includes control equipment 12 whose operation will be described in more detail later in this document.
- the ingestion node 11 and the control equipment 12 are included in the same equipment belonging to the content distribution network CDN.
- the content is transmitted either through an uplink communication link established directly, that is to say without an intermediate node, between the supplier equipment 10 and the control node 12, or, as shown in FIG. 1, through an uplink established between the supplier equipment 10 and the control node 12 and comprising a plurality of intermediate nodes 13-15.

- content such as a video
- Such content consists of a plurality of data packets.
- the user of the supplier equipment 10 wishes to broadcast or “stream” content being acquired to his followers.
- the content is of the real-time type.
- the content must be transmitted to an ingestion node 11 of a content distribution network CDN so that the content is prepared for its distribution.
- the content may be assembled with other content prior to its distribution.
- Once the content to be broadcast has been prepared, and possibly stored in a cache server (not shown in the figures) of the CDN content delivery network, it is broadcast by one or more equipment of the CDN content delivery network to the equipment of the followers. wishing to access said content.
- the user of the supplier equipment 10 is a natural person, he does not necessarily have a pre-established content ingestion contract with the managing operator of the CDN content distribution network in which the transmission conditions such that, for example, the throughput of the uplink between the provider equipment 10 and the ingestion node 11, the latency time, the round trip time (or Round Trip Time RTT in English) and the pricing conditions of ingestion according to these transmission conditions are specified according to a location of the supplier equipment 10 at the time of acquisition and ingestion of the content, as opposed to a content supplier, which has such contracts to transmit its content to an ingestion node 11 of the CDN content distribution network.
- the transmission conditions such that, for example, the throughput of the uplink between the provider equipment 10 and the ingestion node 11, the latency time, the round trip time (or Round Trip Time RTT in English) and the pricing conditions of ingestion according to these transmission conditions are specified according to a location of the supplier equipment 10 at the time of acquisition and ingestion of the content, as opposed to a content supplier, which has such contracts to transmit
- the supplier equipment 10 prior to the transmission of the content to the ingest node 11, the supplier equipment 10 implements a step E2 of negotiating the conditions for transmitting the content with a control equipment 12 belonging to the content distribution network CDN depending on the location of the supplier equipment 10, in particular by specifying whether the latter is located indoors or outdoors because this impacts the quality of the transmission.
- Telemetry data belongs to a group comprising among others:
- the identifier can advantageously include the identifier of an operator ensuring the management of the intermediate node 13 - 15,
- this quality of service being able, according to an example, to be represented by a qualitative indication of the processing of the packet during its routing towards the ingestion node 11,

- the user of the supplier equipment 10, or a content delivery application previously installed in the supplier equipment 10, selects the offer that suits him, that is to say he selects one or more conditions of transmission which correspond to its situation, for example the indoor or outdoor location of the supplier equipment 10, the nature of the connection of the supplier equipment 10 with a communication network, ie wired or wireless, Wi-Fi, Bluetooth, etc and its budget.
- Such transmission conditions are materialized by values of one or more telemetry data described above and associated with a reward.
- the supplier equipment 10 transmits a message MGS1 intended for the control equipment 12 identifying the selected set of transmission conditions received during the negotiation step.
- the supplier equipment 10 and the control equipment 12 also exchange, during step E2, data for the implementation of a reward, such as by example the implementation of a payment transaction, relating to the transmission of content.
- data are, for example, bank details of the user of the supplier equipment 10 and of an operator of the CDN content distribution network, or even a customer identifier of the user of the supplier equipment 10 allowing the operator of the CDN content distribution network to pass on the amount of the content transmission service to a telephone bill for the user of the supplier equipment 10.

- other means of carrying out the payment transaction can be considered as part of this solution.
- the content delivery application installed in the supplier equipment 10 is a browser
- the content delivery application continuously inserts conditional transactions by using application programming interfaces or APIs (for Application Programming Interface in English ) say "web payment” such as those defined by the W3C or that the conditional transactions inserted are transferred in accordance with the “Interledger” protocol (https://interledger.org/rfcs/0003-interledger-protocol/) in ILP type packets for “InterLedger packets”.
- the condition linked to the conditional transactions is, in this case, a cryptographic key created by the content delivery application from the set of transmission conditions selected during the negotiation step E2.
- the cryptographic condition is also transmitted in the MGS1 message.
- the transaction will be carried out following a verification step E6, described later, implemented by the control equipment 12, if during this verification step, the control equipment 12 obtains an identical cryptographic key value or equivalent. If not, then the transaction is aborted.
- the provider equipment 10 can, in return for the ingestion of the content by the ingestion node 11, ensure a provision of connectivity, data storage, intermediate node function for a service implemented by the operator of the CDN content distribution network to which the ingestion node 11 belongs. In this case, there is no payment transaction as such but an exchange of services between the user of the provider terminal 10 and the operator of the CDN content distribution network to which the ingestion node 11 belongs.
- the supplier equipment 10 and the control equipment 12 exchange the data for the implementation of a reward relating to the transmission of the content during a step E3.
- These data are, for example, bank details of the user of the supplier equipment 10 and of an operator of the content distribution network CDN, a client identifier of the user of the supplier equipment 10 allowing the operator of the CDN content distribution network to pass on the amount of the content transmission service to a telephone bill for the user of supplier equipment 10, or else an identifier of the supplier equipment 10 such as an IMEI number or a MAC address.
- IMEI number IMEI number
- MAC address identifier of the supplier equipment 10
- other means of realizing the reward such as those specified above, can be envisaged within the framework of the present solution.

- the supplier equipment 10 generates at least one data stream comprising data packets constituting the content, data packets transporting data for the implementation of a reward relating to the transmission of the content and data packets carrying a value of one or more expected telemetry data intended to be used by the control equipment 12 to verify that the conditions for triggering the reward are verified.
- the data packets carrying a value of one or more expected telemetry data are inserted on the fly into the data stream thus generated.
- the supplier equipment 10 In a second implementation, the supplier equipment 10 generates a first data stream comprising the data packets constituting the content, a second data stream comprising the data transporting a value of one or more telemetry data expected, and in the case where they have not been transmitted during step E2, a third data stream comprising the data for the implementation of a reward relating to the transmission of the content.
- These three data streams are then multiplexed with a view to their transmission to the ingest node 11.
- each of these three data streams can take the form of a “stream” conforming to the QUIC protocol (Quick UDP Internet Connections), currently being standardized at the IETF (Internet Engineering Task Force) which are then multiplexed.

- control equipment 12 verifies the conformity of the actual transmission conditions of the content with the expected transmission conditions of the content negotiated during the step E2.
- the control equipment 12 determines a wandering time representative of a difference between an actual transit time of the data packet in question, and an expected transit time negotiated during step E2.
- control equipment 12 determines that the value of the wander delay is less than the threshold negotiated between the supplier equipment 10 and the control equipment 12 during step E2, the effective transit delay and the delay expected transit match. The actual transmission conditions are then considered to conform to the expected transmission conditions.
- the control equipment 12 measures a difference between an effective transit schedule of a data packet constituting content through an intermediate node 13-15, and an expected transit time of a data packet constituting the content through an intermediate node 13-15.
- the difference thus determined is less than the threshold negotiated between the supplier equipment 10 and the control equipment 12
- the effective transit schedule and the expected transit schedule correspond.
- the actual transmission conditions are then considered to conform to the expected transmission conditions.
- the control equipment 12 verifies the presence of data packets introduced into the content by at least one of the intermediate nodes 13-15 and comprising an identifier of the intermediate node 13-15. If such an identifier of the intermediate node 13-15 is present, then the actual transmission conditions are then considered to conform to the expected transmission conditions.
- the intermediate nodes 13-15 can also insert time information such as, for example, crossing times, crossing times, processing times of a previous sequence of data packets, etc., into the data packets that they introduce into the content in order to allow the control equipment 12 to verify compliance with other transmission conditions.
- time information such as, for example, crossing times, crossing times, processing times of a previous sequence of data packets, etc.
- the control equipment 12 determines a "effective" cryptographic key from the effective telemetry data. If the “effective” cryptographic key thus obtained corresponds to the cryptographic key created by the content delivery application, then the effective transmission conditions are then considered to comply with the expected transmission conditions.
- control equipment 12 triggers the reward relating to the ingestion of the data content in a step E7.
- the control equipment 12 transmits an acknowledgment message ACK intended for the supplier equipment 10 indicating that the content has been ingested in accordance with the expected transmission conditions.

- control equipment 12 does not trigger the reward relating to the ingestion of the data content.
- the control equipment 12 transmits, in a step E9, a NACK failure message intended for the supplier equipment 10 indicating that if the content has been ingested by the ingestion node 11, this ingestion has not been not carried out in accordance with the expected transmission conditions.
- a lesser reward can be a remuneration lower than the maximum remuneration that can be collected when all the transmission conditions are respected, or the performance of a lesser service by the supplier equipment 10, for example the latter can store a volume lower data.
