Detailed Description
In view of the deficiencies in the prior art, the inventors of the present invention have made extensive studies and extensive practices to provide technical solutions of the present invention. The technical solution, its implementation and principles, etc. will be further explained as follows.
The invention provides a method for realizing seamless switching of video program sources of video users based on an OpenFlow switch, which utilizes a group table and a flow table defined by OpenFlow Spec and defined by unified standards to realize the seamless switching of the video program sources of the video users through the OpenFlow switch.
The Group Table of OpenFlow is a template of behavior set in OpenFlow semantics, and is composed of multiple groups entries, where each Group Entry has the following structure:
| Group Identifier | Group Type | Counters | Action Buckets |
wherein:
1) group Identifier: a 32-bit unsigned integer, the unique identifier of the Group Entry;
2) group Type: the Group type determines the semantics of an action Group and the processing behavior of the data packet;
3) counters: a counter, statistics of packets processed by the Group Entry.
4) Action Buckets: action buckets, an ordered list of Action buckets, each Action Bucket containing a set of Action sets and their parameters.
The OpenFlow Spec defines four Group types in total, wherein the four Group types are All/Select/index/Fast-failure, each Group can comprise one or more Action packet members, each Action packet member can carry a Watch _ port attribute, and the technical scheme of the invention uses the Action Group groups of All types and Fast-failure (FF) types.
A Group Table of the type ALL executes ALL actions in the Action packets without considering the content of the Watch _ port, each packet member forwards the Action packets, and the Group Table of the type is mainly used for multicast or broadcast of a packet, and a Group Entry structure diagram of the Group Table is shown in fig. 2 a.
The Group of type FF is equivalent to a Group of a master/slave mode, which only executes one packet at a time and executes the packet which is arranged at the top, and the Watch _ port attribute is a packet member of Up, if the Watch _ port changes to Down, the next Watch _ port attribute is a Group of Up. The schematic diagram of the Group Entry structure is shown in fig. 2 b.
Fig. 3 is a schematic diagram of switching program sources by a video user according to an exemplary embodiment of the present invention, where a scene is shown in which a user 2 switches from a program source 1 to a program source 2, and the process is as follows:
(1) the OpenFlow switch creates 2 FF-groups which are respectively used for receiving the program source 1 and the program source 2, each FF-Group is respectively nested with two All-groups to serve as a main member Group and a standby member Group, and each All-Group comprises a member user set used for receiving the corresponding program source.
(2) The main member nested ALL-Group1 in the FF-Group1 corresponding to the program source 1 comprises a user 1, a user 2 and a user 3, and the standby member Group ALL-Group2 comprises the user 1 and the user 3 but does not comprise the user 2 of the member to be switched.
(3) The main member nested ALL-Group3 in the FF-Group2 corresponding to the program source 2 comprises a user 4, a user 5 and a user 6, and the standby member Group ALL-Group4 comprises the user 4, the user 5, the user 6 and the user 2 as the member to be switched.
(4) When no switching occurs, both FF-groups execute ALL-Group1 and ALL-Group3 of the main member nest, and program source 1 is received by user 1, user 2, and user 3, and program source 2 is received by user 4, user 5, and user 6.
(5) When switching occurs, the Watch-Port corresponding to two FF-Group main members (buckets) is set to be in a Down state, at the moment, the receiving state of the main member Group is forbidden, and the receiving state of the standby member Group is activated.
(6) After the reception status of the standby member groups ALL-Group2 and ALL-Group4 of the two FF-groups is activated, the program source 1 is received by the user 1 and the user 3, and the program source 2 is received by the user 2, the user 4, the user 5, and the user 6. Thus, the user 2 switches from the reception program source 1 to the program source 2.
It should be noted that, in the process of switching the program source by the video user, the setting of the member user is in a static preset mode, and the main purpose is to enable a person skilled in the art to clearly understand the core idea of the technical scheme of the present invention.
As a preferred embodiment of the technical solution of the present invention, the dynamic switching process includes member user editing operations, and specifically includes:
as shown in fig. 3, after the OpenFlow switch receives the switching request of the user 2, the control system of the switch correspondingly edits the member users in the standby member groups ALL-Group2 and ALL-Group4, so that the standby member Group ALL-Group2 includes the user 1 and the user 3, but does not include the member user 2 to be switched; the standby member Group ALL-Group4 includes user 4, user 5, user 6, and user 2, which is the member to be switched. And after the editing is finished, setting the Watch _ port state value corresponding to the main member corresponding to the FF-Group to Down, and activating the receiving state of the standby member Group, thereby finishing the switching. Wherein Watch _ port may be controlled using a software virtual interface.
Since the FF-Group type can change the forwarding behavior of the switch by itself without requesting a remote controller in advance, packet loss hardly occurs when packet switching occurs in SDN data exchange in this mode. And before the switching action occurs, the user to be switched already exists in the member group to be switched, and compared with the prior art, the time delay of leaving the member group and joining a new member group by the user does not exist when the switching occurs. And the process from the switching request of the user to the adjustment of the user to the new member group does not generate time delay influence on the switching, and video blockage or screen blackness cannot be caused. Therefore, the technical scheme of the invention adopts the nested All-Group in the FF-Group and can achieve the effect of seamless switching when the video user switches the program source to the greatest extent by adopting the FF-Group master-slave switching mode.
Correspondingly, the invention also discloses a system for realizing seamless switching of the program source of the video user based on the OpenFlow switch, which comprises a program source management module, a monitoring module and the OpenFlow switch.
The program source management module is configured to manage a receiving relationship between a program source and a user member group, for example, in a case that switching does not occur in fig. 3, the program source 1 is received by the user 1, the user 2, and the user 3, and the program source 2 is received by the user 4, the user 5, and the user 6;
the monitoring module is used for notifying the OpenFlow switch when monitoring that a program source switching request occurs;
the OpenFlow switch comprises more than two Fast-Failover type action groups at least used for receiving different program sources, two All type action groups are nested in the Fast-Failover type action groups and respectively used as a main member group and a standby member group, and the main member group and/or the standby member group comprise member users for receiving corresponding program sources; when the main member group is in a receiving activation state, the corresponding standby member group is in a receiving prohibition state; when the standby member group is in a receiving activation state, the corresponding main member group is in a receiving prohibition state;
and after the OpenFlow switch acquires the program source switching notification sent by the monitoring module, editing the member users of the member group in the reception prohibition state in the Fast-Failover type action group receiving the related program source, and switching the receiving states of the main member group and the standby member group corresponding to the related program source after the editing is finished so as to complete the program source switching of the users.
The system also comprises a user editing module which is used for adding member users which receive the related program sources after the program sources are switched into the member group in the receiving prohibition state.
When an OpenFlow switch receives a request for switching a member user to be switched from a first program source to a second program source, if a first main member group corresponding to the first program source and a second main member group corresponding to the second program source are in a receiving and activating state, the OpenFlow switch edits a first standby member group corresponding to the first program source and member users of a second standby member group corresponding to the second program source, wherein the first standby member group comprises member users except the member to be switched corresponding to the main member group, and the second standby member group comprises all member users corresponding to the main member group and the member users to be switched;
after the member users of the first standby member group and the second standby member group complete editing, the OpenFlow switch sets the corresponding first main member group and the second main member group in a receiving forbidden state, sets the first standby member group and the second standby member group in a receiving activated state, receives the related program source by the users of the standby member groups, and switches the member users to be switched from receiving the first program source to receiving the second program source.
When the OpenFlow switch receives a request for switching the user to be switched from the first program source to the second program source, if the first standby member group corresponding to the first program source and the second standby member group corresponding to the second program source are in the receiving activation state, the processing process is vice versa.
It should be understood that the above-mentioned embodiments are merely illustrative of the technical concepts and features of the present invention, which are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and therefore, the protection scope of the present invention is not limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
