Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
The method for synchronizing STP protocols in a switching device of a dynamic heterogeneous redundant architecture of this embodiment is used for solving the problem of protocol behavior synchronization between heterogeneous executors in the switching device using the dynamic heterogeneous redundant architecture, and particularly when a certain executor is restarted due to a failure or a new executor is added, the protocol operation on the restarted/newly added executor is not synchronized with the protocols on other executors. As shown in fig. 1, the method includes:
step S101, using a scheduler in a dynamic heterogeneous redundancy architecture as an STP proxy;
step S102, the dispatcher simulates BPDU messages from different ports, sends the BPDU messages to a restarting/newly added heterogeneous executive body, trains the STP protocol on the heterogeneous executive body and leads the state to be consistent with the STP protocol state on other heterogeneous executive bodies;
step S103, synchronously refreshing the timers of the STP protocols on all the heterogeneous executors to ensure that all the protocols run to achieve time synchronization.
The scheduler, as an STP agent, needs to have the capability of grasping basic information of the switching device, where the basic information includes basic information of the root bridge, basic information of the home bridge, role information of the home bridge port, and state information of the home bridge port.
The basic information of the switching equipment can be acquired by the scheduler sending a protocol state query to the heterogeneous executors in the service set, or by the scheduler computing using the BPDU messages actually received by the switching equipment.
The method for the scheduler to train the STP protocol on the heterogeneous executive body is consistent with the method for the switching equipment to calculate in the spanning tree calculation, and the training content comprises the following steps: training the protocol to elect a root bridge; a training protocol elects a root port and establishes association with a root bridge; training protocol elects appointed bridge and appointed port; receiving and processing a TCN message sent by a protocol due to the change of the port state; the inter-protocol timer is synchronized.
When the training protocol elects the root bridge:
the election basis of the root bridge is the priority of the bridge ID, and the smaller the bridge ID is, the higher the priority is;
if the switching equipment is the root bridge, at this stage, the scheduler sends BPDU messages from different ports to the restarting/newly added STP protocol simulation, and the priority of the root bridge provided by the messages is lower than that of the local bridge;
if the bridge is not the root bridge, the root bridge is elected, the scheduler needs to send the BPDU message from the root port to the restarting/newly added STP protocol simulation, and the content of the message is consistent with the content of the root bridge BPDU actually received by the bridge.
When the training protocol elects a root port:
only when the bridge is a non-root bridge, the root port is elected according to the priority: the priority of the connected root bridge, the path cost of reaching the root bridge, the ID of the bridge at the opposite end connected with the port, the ID of the port at the opposite end connected with the port and the ID of the port;
the scheduler simulates and sends a BPDU message from a root port to a restarting/newly added STP protocol, and the content of the message is consistent with the content of a root bridge BPDU actually received by the network bridge;
the scheduler sends BPDU messages from the blocked ports to the restarting/newly added STP protocol in a simulation way, the root bridge information of the BPDU messages is consistent with the actual information, but the path cost is larger than the cost from the root ports, or under the condition of consistent cost, the ID of the opposite end bridge is smaller, and other judgment conditions are analogized in turn;
in this way, the restart/newly-added STP protocol compares BPDU messages sent from different ports, and sets the corresponding port as the root port after calculation, where the corresponding port refers to a port set as the root port in other working protocols.
When the training protocol elects a designated port:
after the above two training steps, the restart/newly added STP protocol (if it is a non-root bridge) has already determined the root bridge and root port information, and will forward the BPDU message from the root bridge to other ports, some of these ports are designated ports, the basis for selecting the designated bridge and designated ports by the spanning tree algorithm is, in order of priority: path cost to root bridge, ID of connected bridge, ID of port connected to LAN;
the scheduler sends BPDU messages from the appointed port to the restarting/newly added STP protocol in a simulation way, the cost of the BPDU messages to the root bridge is larger than that of the BPDU messages sent out from the appointed port by the protocol to the root bridge, and other judgment conditions are analogized in sequence;
the scheduler sends BPDU messages from the blocked ports to the restarting/newly added STP protocol in a simulation mode, the root bridge path cost carried in the BPDU messages is smaller than the root bridge path cost in the BPDU message sent from the port, but larger than the root bridge path cost in the BPDU message received by the root port, and other judgment conditions are analogized in sequence.
When receiving and processing a TCN message sent by a protocol due to the change of the port state:
the dispatcher receives a TCN message sent by a protocol layer because the port state is converted into a forwarding state, and simulates and sends a response message TCA of the TCN, and other information of the message is consistent with the content of the root bridge BPDU actually received by the network bridge and is only at the TC and the response position 1.
The scheduler simulates a root bridge BPDU message with the transmission belt TC;
the scheduler simulates sending a root bridge BPDU message without TC.
Inter-protocol timer synchronization time:
the synchronous timer can adopt a method of refreshing all STP protocol timers on heterogeneous executors in a service set at the same time, namely, a scheduler sends a timer reset message to all the executors at the same time, the STP protocol on the executors sets own identification variables after receiving the message, and the absolute waiting time used in the timeout judgment of the timers is determined according to the identification variables.
As shown in fig. 2, the present invention further provides an apparatus for synchronizing STP protocols in a switching device of a dynamic heterogeneous redundant architecture, which includes a plurality of heterogeneous executors 21 and a scheduler 22;
a plurality of heterogeneous executors 21 on each of which an STP protocol is run;
the scheduler 22, as an STP agent, simulates the BPDU packets from each port, sends the BPDU packets to the restarted/newly added heterogeneous executer, and trains the STP protocol on the heterogeneous executer to make the state of the STP protocol consistent with that of the STP protocols on other heterogeneous executers.
The STP protocol synchronization method and device in the switching equipment of the dynamic heterogeneous redundant architecture are a scheme which does not affect the protocol implementation, do not need to modify the protocol implementation code, can well solve the protocol synchronization problem and have higher use value.
Meanwhile, the invention can also be applied to the cleaning and recovering process of other two-layer protocols consistent with the STP principle, such as RSTP and MSTP protocols, after being modified properly, and the scheme obtained without creative labor still belongs to the protection scope of the invention.
