Definitions
- the present invention relates to the field of telecommunications. More particularly, the present invention relates to group policies within a given entity, such as a business or government.
- group policies allow an administrator to configure browsers Web on personal computers (PC), as well as the operating systems of mobile terminals, for the needs of an entity the administrator can thus, for example, designate a proxy server ("proxy" in English) to use compulsorily , disable functions of a web browser (such as synchronizing with an external service of bookmarks and passwords), or impose security rules for the use of mobile devices (such as locking the mobile after a time activity, or the mandatory use of a PIN to unlock the mobile).
- proxy server proxy
- the invention relates, even more particularly, to computer applications.
- computer application means, in the context of the present invention, any Web or mobile service running on a user terminal, such as a PC, a smartphone or a connected object, and in particular real-time communication services.
- Internet of Things Internet of Things
- Internet of Things Internet of Things
- ITU-T Y.2060 June 2012, ⁇ 3.2.2 International Definition
- the computer applications concerned can be for example Skype, Whatsapp, Viber, Messenger, or Youtube, but also solutions of voice communication over IP (Internet Protocol), video conferencing, email, instant messaging, social networks, blogs, web services in general, and especially those that generate multimedia streams potentially important in terms of throughput such as downloads.
- IP Internet Protocol
- Media streams negotiated during an establishment or modification of a multimedia communication session may be processed in a hierarchical manner by a control entity of the network.
- IETF Internet Engineering Task Force
- RFC 4412 "Communications Resource Priority for the Session Initiation Protocol (SIP),” defines a header field in a SIP-compliant request (Session Initiation). Protocol) called Resource-Priority, which allows you to request priority access to certain network resources (such as network gateways, routers, or SIP proxy servers).
- the SIP header field "Resource-Priority" is populated with one or more domain names.
- a network control entity When a network control entity receives a SIP message including the SIP header field "Resource-Priority", it verifies that the message is valid, and identifies the services associated with the domain names of the field. SIP head "Resource-Priority”. When the network resources are saturated, this control entity may preempt the other current communication sessions not associated with an identified domain name, or insert the SIP request with the "Resource-Priority" header field in a queue waiting for requests to be treated first.
- the mechanism described in the document RFC 4412 thus makes it possible to treat a communication session as a priority, and indirectly all the media streams associated with this session.
- US Pat. No. 7,843,843 discloses an arrangement for prioritizing certain data streams relative to others.
- a device located in a router or gateway and involved in the management of the traffic transmitted to a differentiated services network supporting one or more classes of service, performs a classification of the traffic in terms of applications on the network. for example, the network protocol used (TCP, HTTP, and so on), then identifies the service concerned by this traffic based, among other things, on this classification.
- this device comprises: a packet processor adapted to detect data flows in the network traffic traversing a communication path, said data streams each comprising at least one packet;
- a traffic classification engine for identifying one or more applications in the data streams traversing the apparatus
- a network performance control module capable of controlling the performance of the differentiated service network concerning one or more classes of services supported by the differentiated services network
- This device is capable of tagging data stream packets based on the identified network applications and selected service classes, and then forwarding the data packets to the differentiated service network.
- the present invention thus relates, according to a first aspect, to a multimedia stream marking device.
- Said device comprises means for:
- the identification of a multimedia stream is made as close as possible to the application generating this stream, namely at the level of the device (such as a browser or an operator system) that executes the stream. application.
- the data packets are already marked when they leave this device, and therefore the terminal hosting this device.
- the identification of the service concerned and the marking of the stream are carried out in an external device located downstream of the terminals in which the data streams are generated.
- the administrator of an entity such as a company or a public administration can prioritize certain applications compared to other competing applications, by assigning Quality of Service ("Quality of Service”) levels.
- QoS Quality of Service
- the administrator may, for example, decide to assign the highest QoS level to the WebRTC application allowing conference bridges within the group, then a lower QoS level to the instant messaging application, and finally decide that other communication services (such as Skype) will share the rest of the bandwidth available at the routers of the entity. It may also, for example, guarantee employees of the entity a certain rate of image refresh, or some real-time video resolution, even in the presence of concurrent traffic.
- the flows generated by the terminals of the entity will advantageously, during their passage through the routers of this entity, the subject of a differentiated treatment on the basis of said marking.
- This differentiated treatment may for example be carried out, in a manner known per se, by means of a marking and an arrangement of routers complying with the DiffServ standard, described briefly below.
- the "Traffic Management” (“Traffic Management” or “Queuing Discipline” in English), such as “Hierarchical Token Bucket” (HTB), Codel FQ, "Proportional Integral Controller Enhanced” (PIE ) or “Stochastic Fairness Queuing” (SFQ), consists, for a network administrator, to configure the allocation of network resources such as buffer memory and transmission capacity according to predetermined criteria.
- the invention applies preferentially to routers located in the same administrative domain as the terminals that carry out the marking according to the invention, because the administrators / network operators do not generally trust the markings made by another administrative domain. ; the invention thus aims, in particular (but not exclusively), for a given entity, its local area network (LAN), its secure virtual tunnels ("Virtual Private Network” or "VPN” in English), and its Internet access.
- LAN local area network
- VPN Virtual Private Network
- the invention also relates, according to a second aspect, to a system for prioritizing computer applications implemented by a group of users.
- the system is remarkable in that it comprises:
- At least one router capable of taking into account said marking to apply to the multimedia flows traversing said router differentiated service levels according to the computer applications generating these multimedia streams.
- the invention also relates to a computer program downloadable from a communication network and / or stored on a computer readable medium and / or executable by a microprocessor.
- This computer program is notable in that it includes instructions for managing the operation of the media flow marking device succinctly set forth above, when executed on a computer.
- the invention also relates, according to a third aspect, to a process for marking multimedia streams.
- the method comprises the following steps:
- FIG. 1 represents a network architecture able to implement the invention
- FIG. 2a represents, at the output of a Web browser, a list of interactive real-time streams generated by a non-prioritized application, and
- FIG. 2b represents, at the output of a Web browser, a list of interactive real-time streams generated by a prioritized application.
- DiffServ https://en.wikipedia.org/wiki/Differentiated_services
- the DiffServ mechanism can, for example, be used to provide low latency to critical network traffic, such as voice or streaming media, while providing a simple "best effort" service ( “Best effort” in English) to non-critical services such as web traffic or file transfers.
- the DiffServ mechanism For classification of data packets, the DiffServ mechanism uses a 6-bit "Differentiated Services Code Point” (DSCP) value in the "Differentiated Services” field ("Differentiated Services”). "Or DS in English) of 8 bits contained in the header of IP packets.
- DSCP Differentiated Services Code Point
- the DiffServ mechanism operates in accordance with the traffic classification principle of placing data packets in a number of traffic classes, rather than differentiating traffic based on the characteristics of each stream.
- Each router in the network is configured to handle the traffic differently depending on its class; this treatment consists, for example, of transferring the packets of a class in priority over those of other classes of traffic, to guarantee a minimum bit rate for a class of traffic, or to put the packets of a certain class in a queue active waiting time whose length is managed (by deleting packets) so as not to exceed durably a target transit time in the router.
- the DSCP marking can be done at the source by an application installed on a terminal dedicated to this application; on the contrary, the present invention relates to multimedia streams (for example from a microphone or a camera) received by a device such as a web browser or an operating system, this device then implementing a packaging of these multimedia streams in the form of data packets, said data packets including a specific marking; moreover, the devices according to the invention carry out this marking, generally, to hierarchize the multimedia streams coming from a plurality of applications;
- a developer could in principle encode a web application so that the streams are marked with a certain DSCP value (for example https://qroups.qooqle.com/forum/?fromqroups#!topic/discuss- webrtc / 96TvhNJkYqs), but this possibility is not used in practice because the application developer should query the administrator of each company to whom he provides such an application to determine if the flows of his application, for this company , must be marked with a particular DSCP value; this would obviously pose a scalability problem for application developers; in addition, this would require the administrator to replace their applications following each change in the company's traffic policy.
- DSCP value for example https://qroups.qooqle.com/forum/?fromqroups#!topic/discuss- webrtc / 96TvhNJkYqs
- Figure 1 represents a company 100.
- a group of employees of this company uses terminals such as personal computers, mobile terminals or connected objects; these terminals are designated 200a, 200b, 200c, in Figure 1.
- the streams generated by these terminals go through routers of a LAN or Wide Area Network (WAN) of the enterprise.
- a Customer Premises Equipment (CPE) gateway denoted CPE in FIG. 1, serves as an interface between said terminals 200a, 200b, 200c, and said network of the company.
- CPE Customer Premises Equipment
- Enterprise 100 has determined a certain business policy of associating certain computer applications (denoted Web App ID X, Web App ID Y, and so forth, in Fig. 1) respectively, used by the terminals of said group. employees, respective QoS levels.
- This association according to the invention is, consequently, integrated by a network administrator of the company into a tool describing the company policy, for example the directory management tool "Active Directory” called GPME (Group Policies Management Editor) in a Windows environment.
- GPME Group Policies Management Editor
- This association according to the invention is then recorded in one or more database (s) accessible to the computer devices embedded in the terminals 200a, 200b, 200c, said group such as Web browsers personal computers and / or the operating systems ("operating systems") of mobile terminals or connected objects.
- database accessible to the computer devices embedded in the terminals 200a, 200b, 200c, said group such as Web browsers personal computers and / or the operating systems ("operating systems") of mobile terminals or connected objects.
- these devices comprise means for marking the data packets transmitted by these terminals. For example, it is possible, for this purpose, to use a DSCP type marking as described above.
- Such a device receives a multimedia stream generated by an application executed by this device, it implements the following steps (it will be noted that there is generally a plurality of applications executed simultaneously by this device).
- the device identifies the application that generated said multimedia stream by means of an application identifier, such that, in the case of the company's Web browsers, the Uniform Resource Identifier (URI) of the application, or, in the case of mobile terminal operating systems, a downloadable classic downloadable application identifier, for example the naming of a "java package” (in the format net.name-of-developer.name- du-package ") or the" Bundle ID "(in the format com.username.application-name) of an application under Apple's IOS.
- an application identifier such that, in the case of the company's Web browsers, the Uniform Resource Identifier (URI) of the application, or, in the case of mobile terminal operating systems, a downloadable classic downloadable application identifier, for example the naming of a "java package” (in the format net.name-of-developer.name- du-package ”) or the" Bundle ID "(in the format com.username.application-name) of an
- a browser can thus determine that a given stream, in HTTPS format, was generated by the Whatsapp application, and that another given stream, also in HTTPS format, was generated by the Skype application, these two applications being executed by the browser at the moment considered.
- the device consults a database as mentioned above, ie indicating which applications are to be marked, and which are the application / value pairs of marking. Note that this database can be contained in the terminal hosting the device, or in an external module connected to said terminal.
- the device accordingly marks the data packets that it transmits.
- This marking (denoted DSCP X, DSCP Y, and so on, in FIG. 1) is therefore representative of the level of QoS associated with each application (denoted Web App ID X, Web App ID Y, and so on) in accordance with FIG. corporate policy.
- Figures 2a and 2b show, at the output of a web browser, a list of interactive real-time streams obtained with a network analysis tool, such as Wireshark.
- FIG. 2a corresponds to the case where said streams are generated by an unscheduled application. We see that the field "Differentiated Services Code Point" is valued at "Default”. These streams will therefore be handled by the enterprise routers with a default QoS level.
- Figure 2b corresponds to the case where said flows are generated by a prioritized application.
- the field "Differentiated Services Code Point” is valued at "Expedited Forwarding". These streams will therefore benefit from a quick transfer to the level of the routers of the company.
- the invention can be implemented in web browsers of personal computers, operating systems of mobile terminals or connected objects, using software and / or hardware components.
- the software components can be integrated into a typical network node management computer program. Therefore, as indicated above, the present invention also relates to a computer system.
- This computer system conventionally comprises a central processing unit controlling signals by a memory, as well as an input unit and an output unit.
- this computer system can be used to run a computer program with instructions for managing the operation of a multimedia stream marking device according to the invention.
- the invention also relates to a downloadable computer program from a communication network comprising instructions for managing the operation of a multimedia stream marking device according to the invention, when it is executed on a computer.
- This computer program may be stored on a computer readable medium and may be executable by a microprocessor.
- This program can use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any another desirable form.
- the invention also relates to an information carrier, irremovable, or partially or completely removable, readable by a computer, and comprising instructions of a computer program as mentioned above.
- the information carrier may be any entity or device capable of storing the program.
- the medium may comprise storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM, or a magnetic recording medium, such as a hard disk, or a USB key. (“USB flash drive" in English).
- the information medium may be a transmissible medium such as an electrical or optical signal, which may be conveyed via an electrical or optical cable, by radio or by other means.
- the computer program according to the invention can in particular be downloaded to an Internet type network.
