The invention is further elucidated with reference to the drawing.
As shown in fig. 1, the present invention provides a multicast data processing method using a default VLAN, which specifically includes the following steps:
s11, obtaining VLAN information identification contained in the joining or leaving message;
s12, searching whether a matched multicast configuration VLAN exists or not according to the VLAN information identifier, if the matched multicast configuration VLAN cannot be found, defining the message as joining or leaving a default group VLAN, and creating a related multicast group table entry in real time;
s13, forwarding the multicast protocol message to a multicast routing port according to the multicast protocol definition;
s14, after grouping by using a default group VLAN, when a multicast data source is forwarded, a VLAN identifier carried by the data source is a default group VLAN identifier;
s15, when using default group VLAN group, when sending query message, the query message uses VLAN mark carried in original request message to query.
The step obtains VLAN information identification contained in the added or separated message, wherein the message is a single-layer or double-layer VLAN message.
The step of obtaining VLAN information identification contained in the joining or leaving message further comprises the following steps:
and S111, when the default group VLAN is used for grouping, the VLAN identification information carried by the user side and whether the VLAN message is a single-layer VLAN message can be ignored.
The step of searching whether a matched multicast configuration VLAN exists or not according to the VLAN information identifier, if the matched multicast configuration VLAN cannot be found, defining the message as joining or leaving a default group VLAN, and establishing a related multicast group entry in real time, and the method further comprises the following steps:
s121, configuring original multicast information configuration and default group VLAN identification of equipment, and when the original multicast information configuration cannot be grouped, grouping by using the default group VLAN;
the step of forwarding the message according to the multicast protocol definition further comprises the following steps:
s131, judging whether the created group uses a default group VLAN group, if so, replacing the VLAN identification of the multicast protocol message with the default group VLAN and then forwarding.
That is to say, the invention provides a multicast data processing method using default VLAN, comprising the following steps:
step S1, the VLAN information identifier carried in the join or leave message initiated by the user is analyzed, and the VLAN information identifier may be a single-layer or double-layer VLAN message.
Step S2, find whether there is a matching multicast configuration VLAN in the device, and if not, consider that the packet is joined or separated from the default group VLAN, thereby grouping the related multicast group entries.
Step S3, after grouping on the device, the multicast protocol defines that the request message needs to be forwarded to the routing port, and at this time, when the default group VLAN is used for grouping, the VLAN identifier of the message should be replaced with the default group VLAN, and then forwarding is performed.
Step S4, after the device uses the default group VLAN to form a group, when forwarding the multicast data source of the routing port to the user port, the VLAN id carried by the data source is the default group VLAN id.
Step S5, when using the default group VLAN to group, the device should use the VLAN id carried in the original request message to query when sending the query message to the user port.
The step S1 specifically includes: when the default group VLAN is used for grouping, VLAN identification information carried by a user side and whether the VLAN information is a single-layer VLAN message can be ignored.
The step S2 specifically includes: the original multicast information configuration can still be configured in the device, when the original multicast configuration cannot be grouped, the device uses the default group VLAN for grouping, and at the moment, the device needs to ensure that the default group VLAN identification is assigned.
The step S3 specifically includes: the default group VLAN is used for identifying the group, and the VLAN identification of the original message content cannot be continuously used on the routing port for transmission due to the characteristics of the information of the added or separated message VLAN identification, so the message VLAN identification needs to be replaced by the default group VLAN identification and then sent to the routing port.
The step S4 specifically includes: the default group VLAN identifications are grouped, when the multicast data stream is forwarded, the VLAN identification carried by the data stream is still the default group VLAN identification, and the data stream does not need to be translated into a user state VLAN. For the user side, what the multicast data goes through is a multicast channel, and the configuration of the multicast channel should be a default group VLAN identifier.
The step S5 specifically includes: the multicast protocol message passes through the unicast channel, so that when the device queries, the device needs to query by using the query message of the user side VLAN identification information. That is, when the default group VLAN is grouped, the original user-mode VLAN identification information needs to be stored for query.
In other words, the switching device operates in a normal multicast configuration environment, where a default multicast VLAN is added to the device. When a new user initiates a join request, the device receives the join message and judges the VLAN of the join message, and if the VLAN is in the original multicast configuration table entry, the VLAN is normally added into the original multicast configuration group; if the user VLAN can not be found in the original multicast configuration table item, the join request is added into the default multicast group VLAN, and the multicast flow is forwarded by the multicast group VLAN. And the user VLAN is recorded in the multicast forwarding table item on the equipment, and is used for carrying out general group and specific group query by using the VLAN when a message is queried.
The configuration of the VLAN of the user side can be ignored, and only the multicast group VLAN of the video source which is configured by the equipment is the default multicast VLAN. Moreover, unnecessary multicast group configuration in the device can be reduced, and the device can be ensured to be successfully added into the multicast group only by configuring the default multicast group VLAN in engineering application.
In summary, a method for processing multicast data using a default VLAN is provided, which includes the following steps:
step S1, analyzing VLAN information identification carried in the join or leave message initiated by user, which can be single layer or multi-layer VLAN message
Step S2, searching whether there is matching multicast configuration VLAN in the device, if it can not be found, then considering the message is joining or leaving default group VLAN, thereby making related multicast group table item group
Step S3, after grouping on the device, the multicast protocol defines that the request message needs to be forwarded to the route port, at this time, when the default group VLAN is used for grouping, the VLAN identification of the message should be replaced by the default group VLAN, and then forwarding is carried out
Step S4, after the device uses the default group VLAN to form the group, when the multicast data source of the route port is forwarded to the user port, the VLAN mark carried by the data source is the default group VLAN mark
Step S5, when using default group VLAN group, when the device sends query message to user port, it should use VLAN mark carried in original request message to query
When configuring the related multicast group configuration on the device, the default group VLAN of the device needs to be designated at the same time, so as to ensure that the device can use the designated default group VLAN to perform grouping when the device cannot normally join the VLAN group used by the user.
Compared with the prior art, the invention has the beneficial effects that: the configuration of a plurality of unnecessary multicast groups in the equipment can be reduced, and the equipment can be ensured to be successfully added into the multicast group only by configuring the default multicast group VLAN in engineering application. The configuration of the VLAN of the user side can be ignored, and only the multicast group VLAN of the video source which is configured by the equipment is the default multicast VLAN.
Specifically, in the embodiment of the present invention, as shown in fig. 2 to 3, the user has three ways of requesting to join from left to right, the first two ways are existing practical applications, and the third multicast default VLAN is the subject content of this time.
It can be seen that on the OLT device, two modes can be configured:
the first is that the device uses the VLAN information carried by the join message to perform multicast group configuration, at this time, the VLAN identifier carried by the join message needs to be ensured to be the VLAN identifier configuration allowed on the device, and the VLAN identifier is ensured to be consistent with the multicast group VLAN identifier of the uplink multicast source server, and the application is a basic application mode in the multicast protocol;
the second is based on the special application of the first configuration, that is, when the VLAN identifier carried by the added message is ensured to be the VLAN identifier configuration allowed on the device, the VLAN identifier carried by the added message is inconsistent with the multicast group VLAN identifier of the uplink multicast source server, and the device needs to replace the group VLAN identifier with the VLAN identifier of the added message when forwarding the multicast group of the uplink multicast source server according to the VLAN identifier carried by the added message;
both of the above applications have their limitations, and this embodiment describes a more adaptable application mode. The VLAN identification carried in the adding process is not required to be configured, and for the adding message which is not added into the first or second configuration normally, the adding message is directly added into the multicast group according to the multicast default VLAN identification configured on the equipment, and the multicast group message is directly forwarded to the adding port without modifying any VLAN identification.
In general, the principle of the present embodiment is as follows:
in a multicast environment, it is necessary to ensure that a unicast link is clear, which is to ensure the transmission of multicast protocol messages, that is, what the multicast protocol messages go is the unicast link. Therefore, for part of engineering applications, the configuration of some unicast lines is fixed, that is, on the premise that a unicast VLAN cannot be changed and a multicast group VLAN of an uplink video source cannot be changed, at this time, a situation that the unicast VLAN is different from the multicast VLAN may occur, and if a device uses different user VLANs and multicast VLANs to perform multicast port configuration, the result may become the second configuration mode, and the multicast stream VLAN is translated into a multicast stream of the user VLAN, so that the multicast stream VLAN is different from a multicast link VLAN configured by a user end, and a result that multicast is not available is caused. In this embodiment, according to the default VLAN id configured on the device, the join packet is directly added to the multicast group, and the multicast group packet is directly forwarded to the join port without modifying any VLAN id. So that the downstream device can directly receive the multicast data stream with the default VLAN identification.
The embodiment can be applied to multicast communication engineering, is an effective method and can bring certain benefits. The invention belongs to a multicast VLAN data processing mode of a multicast communication protocol, in the application of the existing communication engineering, when a user joins in a multicast group, the user needs to join in the multicast group by using a VLAN added with a message, or after the user appoints a user VLAN, a video stream of the multicast group VLAN is translated into the user VLAN. However, in practical engineering application, the problem that a user terminal cannot use a multicast group VLAN or select a user VLAN to join in multicast and translate is solved by the present invention, that is, a unicast VLAN of a user terminal cannot be kept the same as a multicast VLAN, which results in that the user terminal cannot normally join in a multicast group.
