In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Fig. 1 is a flowchart illustrating a method for updating a role of a DR device according to an embodiment of the present disclosure, where the method is applied to a distributed aggregation system, the distributed aggregation system including two DR devices, and the method includes:
step S1, when the IPL link fails, each DR device receives a role negotiation packet sent by an opposite DR device, where the role negotiation packet includes role information of the DR device that sent the role negotiation packet.
In a possible implementation manner, when the roles of two DR devices in the distributed aggregation system are the same (or a master and a slave are not already separated), both DR devices may send a role negotiation packet to a DR device of an opposite end. For example, when the Keepalive link is not configured in the distributed aggregation system and the IPL link fails, after the Keepalive link is established, roles of two DR devices in the distributed aggregation system are both master devices (or both slave devices), and both DR devices may send a role negotiation packet to a DR device of an opposite end.
The role negotiation message may use an existing message format, for example, the role negotiation message may use a format of a Keepalive message.
In one possible implementation, the role information includes role priority and/or bridge MAC. The role negotiation message sent by each DR device may include its own role priority and/or bridge MAC.
Each DR device may send a plurality of role negotiation messages, or may continuously send role negotiation messages, so as to ensure that the DR device of the opposite end can receive the role negotiation messages.
Step S2, each DR device sends a role negotiation response message according to the received role negotiation message, where the role negotiation response message includes role information of the DR device that sent the role negotiation response message.
In a possible implementation manner, after each DR device receives a role negotiation message sent by a DR device of an opposite end, a role negotiation response message is sent to the DR device of the opposite end. The role negotiation response message may use an existing message format, for example, the role negotiation response message may use a format of a Keepalive message.
And each DR equipment receives the role negotiation response message sent by the opposite end DR equipment and analyzes the role negotiation response message to obtain the role priority and/or the bridge MAC of the opposite end DR equipment.
In a possible implementation manner, after each DR device receives a role negotiation response message sent by an opposite-end DR device, sending of the role negotiation message may be stopped.
Step S3, each DR device determines its updated role according to its own role information and the role information of the peer DR device.
In a possible implementation manner, each DR device determines its updated role according to its own role priority and/or bridge MAC and the role priority and/or bridge MAC of the peer DR device obtained through analysis. For example, if the role priority value of the current DR device is smaller than that of the peer DR device, the updated role of the current DR device is determined to be the master device. If the role priority value of the current DR equipment is equal to the role priority value of the opposite-end DR equipment, and the bridge MAC value of the current DR equipment is smaller than that of the opposite-end DR equipment, the current DR equipment determines the updated role as the main equipment. The correspondence between the updated role and the value of the role priority and/or the value of the bridge MAC can be set as required.
In this embodiment, when the IPL link fails, each DR device sends a role negotiation packet to the peer DR device, and analyzes the received role negotiation response packet sent by the peer DR device to obtain role information of the peer DR device. And the two DR devices determine the updated roles of the two DR devices according to the same role judgment rule. By sending the role negotiation message and the role negotiation response message, each DR device determines the updated role of the DR device, and when the IPL link is recovered, each DR device can recover to work according to the updated role, so that the problem of secondary shutdown of the device caused by different roles is solved.
In one possible implementation, the method further includes:
and determining that the updated role of the slave device is that the DR device of the slave device closes the ports except the reserved port.
In a possible implementation manner, if the updated role determined by the current DR device is a slave device and the updated role of the peer DR device is a master device, the current DR device closes (MAD DOWN) other ports except the reserved port.
And if the updated role determined by the DR equipment at the opposite end is the slave equipment and the updated role of the current DR equipment is the master equipment, closing (MADDOWN) other ports except the reserved port by the DR equipment at the opposite end.
In this embodiment, the updated role is that the DR device of the slave device closes the ports except the reserved port, so that the problem of secondary closing of the device due to different roles when the IPL link is restored can be avoided.
In a possible implementation manner, the role negotiation packet and the role negotiation response packet further include type information, where the type information includes a type that supports role update and a type that does not support role update.
Fig. 2 is a flowchart illustrating a method for updating a role of a DR device according to an embodiment of the present disclosure, where the method is applied to a distributed aggregation system, as illustrated in fig. 2, and the distributed aggregation system includes a master DR device and a slave DR device, and the method includes:
step S10, when the IPL link fails, the master DR device sends a first role negotiation packet to the slave DR device, where the first role negotiation packet includes role information of the master DR device.
In a possible implementation manner, when two DR devices in the distributed aggregation system are respectively a master device or a slave device, for example, when a Keepalive link is configured in the distributed aggregation system, and roles of the two DR devices are one master device and one slave device, the IPL link fails, and the master DR device sends a first role negotiation message to the slave DR device. The first role negotiation message may use an existing message format, for example, the first role negotiation message may use a format of a Keepalive message.
In one possible implementation, the role information includes role priority and/or bridge MAC. The first role negotiation message sent by the master DR device may include the role priority and/or the bridge MAC of the master DR device itself.
The master DR device may send a plurality of first role negotiation messages, and the master DR device may also continuously send the first role negotiation messages to ensure that the slave DR device can receive the first role negotiation messages.
Step S20, the master DR device receives a first role negotiation response packet sent by the slave DR device, where the first role negotiation response packet is sent by the slave DR device after receiving the first role negotiation packet, and the first role negotiation response packet includes role information of the slave DR device.
In a possible implementation manner, after receiving the first role negotiation message sent by the master DR device, the slave DR device sends a first role negotiation response message to the master DR device. The first role negotiation response message may use an existing message format, for example, the first role negotiation response message may use a format of a Keepalive message. The first role negotiation response message transmitted from the DR device may include the role priority and/or bridge MAC of the DR device itself. And the master DR equipment receives the first role negotiation response message sent by the slave DR equipment, and analyzes to obtain the role priority and/or the bridge MAC of the slave DR equipment.
In one possible implementation manner, after the master DR device receives the first role negotiation response message sent from the DR device, the master DR device may stop sending the first role negotiation message.
Step S30, the master DR device determines its updated role according to the role information of the slave DR device and its own role information.
In one possible implementation, the master DR device determines its updated role according to its role priority and/or bridge MAC and the role priority and/or bridge MAC of the slave DR device obtained through parsing. For example, if the role priority value of the master DR apparatus is smaller than the role priority value of the slave DR apparatus, the master DR apparatus determines the updated role thereof as the master. If the role priority value of the master DR device is equal to the role priority value of the slave DR device, and the bridge MAC value of the master DR device is smaller than the bridge MAC value of the slave DR device, the master DR device determines that the updated role is the master.
And the slave DR equipment determines the updated role of the slave DR equipment by using the same rule as the master DR equipment according to the role priority and/or the bridge MAC of the master DR equipment and the role priority and/or the bridge MAC of the slave DR equipment obtained by analysis. For example, if the role priority value of the slave DR apparatus is greater than the role priority value of the master DR apparatus, the slave DR apparatus determines that the updated role thereof is a slave. And if the role priority value of the slave DR equipment is equal to the role priority value of the slave DR equipment, and the bridge MAC value of the slave DR equipment is larger than that of the slave DR equipment, determining the updated role as the slave equipment by the slave DR equipment. The corresponding relation between the value of the role priority and/or the value of the bridge MAC and the determined updated role can be set according to the requirement.
In this embodiment, when the IPL link fails, the master DR device sends the first role negotiation packet to the slave DR device, so that the slave DR device obtains role information of the master DR device after parsing the first role negotiation packet, the slave DR device sends the first role negotiation response packet to the master DR device according to the received first role negotiation packet, and the master DR device parses the first role negotiation response packet to obtain role information of the slave DR device. And the master DR equipment and the slave DR equipment determine the roles updated by the master DR equipment and the slave DR equipment according to the same role judgment rule. By sending the first role negotiation message and the first role negotiation response message, the master DR device and the slave DR device respectively determine updated roles of the master DR device and the slave DR device, and when the IPL link is restored, the master DR device and the slave DR device can restore work according to the updated roles, so that the problem of secondary closing of the devices caused by different roles is solved.
In one possible implementation, the method further includes;
and when the updated role of the main DR equipment is determined to be the slave equipment, the main DR equipment closes the ports except the reserved port.
In one possible implementation, when the updated role determined by the master DR device is the slave device and the updated role of the slave DR device is the master device, the master DR device closes (maddown) the other ports except the reserved port.
And when the updated role determined by the slave DR equipment is the slave equipment and the updated role of the master DR equipment is the master equipment, closing (MADDOWN) other ports except the reserved port by the slave DR equipment.
In this embodiment, when the updated role of the master DR apparatus is the slave apparatus, the master DR apparatus closes the ports except the reserved port, so as to avoid the problem of secondary closing of the apparatus due to different roles when the IPL link is restored.
Fig. 3 is a flowchart illustrating a DR device role updating method according to an embodiment of the present disclosure, where, as shown in fig. 3, step S10 in the DR device role updating method includes:
step S11, when the IPL link fails, the master DR device updates its own role information according to the role change information.
In a possible implementation manner, when the IPL link fails, the role of the DR device may update its own role information according to the received role change information. For example, the master DR device and/or the slave DR device may update their own role priorities or bridge MACs according to the received role change information.
Step S12, the master DR device sends the first role negotiation packet to the slave DR device according to the updated role information.
In a possible implementation manner, the master DR device sends a first role negotiation packet to the slave DR device according to the updated role information. The first role negotiation message comprises role information updated by the main DR equipment. And the main DR equipment determines the updated role of the main DR equipment according to the updated role information of the main DR equipment and the role information of the auxiliary DR equipment obtained by analysis.
The slave DR apparatus may determine its own updated role based on the updated role information of the master DR apparatus and the role information of the slave DR apparatus itself.
In a possible implementation manner, when the IPL link fails and the main DR device does not receive role change information, the main DR device sends a first role negotiation packet according to its own role information, and determines an updated role. When the main DR equipment receives the role change information, the main DR equipment sends a first role negotiation message according to the updated role information and determines the updated role of the main DR equipment again.
In this embodiment, after the master DR apparatus receives the role change information, the master DR apparatus updates its own color reference information; and sending the first role negotiation message to the slave DR equipment according to the updated role information. According to the embodiment, when the role information of the master DR equipment changes, the slave DR equipment can be informed in time, and the master DR equipment and the slave DR equipment can obtain more accurate updated roles.
Fig. 4 is a flowchart illustrating a DR device role updating method according to an embodiment of the present disclosure, and as shown in fig. 4, the DR device role updating method further includes:
step S40, the master DR device receives a second role negotiation packet sent by the slave DR device, where the second role negotiation packet includes role information of the slave DR device, and the role information of the slave DR device is determined according to the role change information of the slave DR device.
In one possible implementation, the second negotiation packet may have the same format as the first negotiation packet. The second role negotiation packet may use an existing packet format, for example, the second role negotiation packet may use a format of a Keepalive packet.
When the IPL link fails, the slave DR device may update its own role priority or bridge MAC according to the received role change information. After the slave DR device updates its own role information, the slave DR device may send a second role negotiation packet to the master DR device. The second negotiation packet may include role information updated by the slave DR device according to the role change information.
The slave DR device may send a plurality of second negotiation messages, or may continuously send the second negotiation messages, so that the master DR device can receive the second negotiation messages.
Step S50, the master DR device sends a second role negotiation response message to the slave DR device according to the second role negotiation message, where the second role negotiation response message includes role information of the master DR device.
In a possible implementation manner, after the master DR device receives the second role negotiation message sent from the slave DR device, the master DR device sends a second role negotiation response message to the slave DR device. The second role negotiation response message may have the same format as the first role negotiation response message. The second role negotiation response message may use an existing message format, for example, the second role negotiation response message may use a format of a Keepalive message.
After receiving the second role negotiation response message sent by the master DR device, the slave DR device may stop sending the second role negotiation message.
Step S60, the master DR device determines its updated role according to the role information of the slave DR device and its own role information.
In a possible implementation manner, the master DR device may determine an updated role thereof according to the role information of the master DR device and the role information of the slave DR device obtained through analysis.
In a possible implementation manner, the slave DR device may obtain role information of the master DR device through parsing according to the received second role negotiation response message sent by the master DR device. The slave DR device may determine its own updated role according to the updated role information of the slave DR device and the role information of the master DR device obtained through analysis.
In this embodiment, after receiving role change information from the DR apparatus, the DR apparatus updates its own role information; and sending a second role negotiation message to the main DR equipment according to the updated role information. And the master DR equipment sends a second role negotiation response message to the slave DR equipment according to the received second role negotiation message. The master DR apparatus and the slave DR apparatus can obtain more accurate updated roles.
In a possible implementation manner, the first role negotiation packet, the second role negotiation packet, the first role negotiation response packet, and the second role negotiation response packet further include type information, where the type information includes a type that supports role update and a type that does not support role update.
Fig. 5 is a schematic diagram illustrating a Keepalive message in a DR device role updating method according to an embodiment of the present disclosure, and as shown in fig. 5, the Keepalive message includes:
the Keepalive Header comprises a version field and a reserved field, wherein the version field and the reserved field can respectively occupy one byte.
Global Information TLV Global Information field, which carries system mac, system priority, system number.
Local Device Information TLV Local Information field, Local Device Information TLV carries Keepalive's transmission time interval, role priority, Device bridge mac.
The type information may be represented by a value of a version field in the keepalive message. The version field may support 2 values, for example, a value of the version field is 1, which indicates that an existing Keepalive message does not have a role update capability, and a value of the version field is 2, which indicates that a Keepalive message applicable to the embodiment of the present disclosure has a role update capability.
The value of the reserved field in the keepalive message can be used to indicate whether the message is a first role negotiation message or a second role negotiation message, or a first role negotiation response message or a second role negotiation response message. The value of the reserved field in the keepalive message can support 3. For example, when the version field value is 1, the existing packet may be represented by a reserved field value of 0, and no role update may be triggered. When the version field value is 2, the message can be represented as a first role negotiation message or a second role negotiation message by using the value of the reserved field as 1; the message may be represented as a first role negotiation response message or a second role negotiation response message by setting the value of the reserved field to 2. With the value of the reserved field being 1 or 2, a role update result error caused by a change in role priority of the DR device or a bridge MAC during a role update can be avoided.
In one possible implementation, if one of the DR devices does not support the role update function in the embodiments of the present disclosure, the distributed aggregation system is configured without role update capability. In this case, keepalive message version sent by the DR device that supports the role update function in the embodiment of the present disclosure may be filled to 2, and the DR device that does not support the role update function in the embodiment of the present disclosure may process as a common keepalive message after receiving the keepalive message whose version is 2. When the IPL link is down, the DR device supporting the role update function in the embodiment of the present disclosure may determine, according to the keepalive message received before, that the DR device of the opposite end does not support the role update function in the embodiment of the present disclosure, and may not send the first role negotiation message to the DR device of the opposite end.
In this embodiment, through the type information, it may be distinguished whether the DR device in the distributed aggregation system supports the role update function in the embodiment of the present disclosure, and the application range of the DR device role update method of this embodiment is wider.
In a possible implementation manner, when no role takes effect in the distributed aggregation system, the establishment of the keepalive session, the role priority change and the bridge MAC change do not trigger the DR device to send the first role negotiation message, the second role negotiation message or the role negotiation message, so as to avoid role election conflict of the DR system.
In a possible implementation manner, under the condition of the IPL link UP, the DR device does not send the first role negotiation packet, the second role negotiation packet, or the role negotiation packet, thereby avoiding role election conflict of the DR system.
Fig. 6 is a block diagram illustrating a DR device role updating apparatus according to an embodiment of the present disclosure, and as shown in fig. 6, the apparatus is applied to a DR device of a distributed aggregation system, and includes:
