What is a parallel gateway
William Taylor
Published Mar 17, 2026
Parallel Gateways. Definition. A parallel gateway splits the sequence flow into two or more parallel flows and joins the parallel flows again. The synchronizing gateway waits until all incoming sequence flows have arrived. Only then is the flow continued.
What is a parallel gateway BPMN?
A parallel gateway is very different than the previous gateways because you don’t evaluate any condition or event. Instead, a parallel gateway is used to represent two concurrent tasks in a business flow. It is the same as a fork in a UML activity diagram.
What does inclusive Gateway mean?
An Inclusive Gateway is one of the most common gateways used in BPMN and is depicted as a diamond with a circle within it. When used as a diverging gateway (splitting the sequence flow into many paths), an inclusive gateway can have 2 or more outgoing paths.
When would you use a parallel gateway?
Parallel gateways are used to represent two tasks in a business flow. A parallel gateway is used to visualize the concurrent execution of activities. A parallel gateway models a fork into multiple paths of execution, or a join of multiple incoming paths of execution.What is the difference between exclusive gateway and inclusive gateway?
The Exclusive Gateway represents the need to make a decision where only one of the paths can be taken. The Inclusive Gateway is used to create both alternative and parallel paths within a Process flow. The Inclusive Gateway represents the need to make a decision where all conditions must be evaluated.
What is parallel gateway in Camunda?
A parallel gateway (or AND-gateway) allows to split the flow into concurrent paths. When a parallel gateway with multiple outgoing sequence flows is entered, all flows are taken. The paths are executed concurrently and independently.
How do I show parallel process in BPMN?
To express parallel flow in BPMN, you use a parallel gateway. A splitting parallel gateway multiplies the incoming sequence flow into several outgoing sequence flows that run simultaneously. A joining parallel gateway waits for all incoming sequences to terminate before combining them all in one outgoing flow.
How many types of gateway are there?
Types of Gateways Unidirectional Gateways − They allow data to flow in only one direction. Changes made in the source node are replicated in the destination node, but not vice versa. They can be used as archiving tools. Bidirectional Gateways − They allow data to flow in both directions.What are the types of gateway?
- VoiP Trunk Gateway.
- Network Gateway.
- Internet-To-Orbit Gateway.
- Media Gateway.
- Payment Gateway.
- Default Gateway.
- IoT Gateway.
- Cloud Storage Gateway.
Complex Gateway. This type of gateway allows you to selectively accept (or restrict) incoming paths and evaluate rules to determine outgoing paths. For example, you can restrict the node to accept only the first three out of four incoming paths, or require input from certain nodes before continuing.
Article first time published onWhat is the gateway that is used to Synchronise combine parallel flows and to create parallel flows?
Definition. A parallel gateway splits the sequence flow into two or more parallel flows or synchronizes or merges the parallel flows again.
What is Gateway in Visio?
BPMN Gateway is a kind of flow objects which is used to direct sequence flows within a process, based on certain condition(s). It acts like a gate that either allows or disallows passage, and possibly control the selection of outgoing flow that pass through the gateway.
What is the difference between exclusive OR and inclusive or?
Inclusive OR allows both possibilities as well as either of them. So, if either A or B is True, or if both are True, then the statement value is True. Whereas Exclusive OR only allows one possibility. So if either A or B is true, then and only then is the value True.
What is the gateway that can be used to create alternative but also parallel paths within a process flow?
A diverging Inclusive Gateway (Inclusive Decision) can be used to create alternative but also parallel paths within a Process flow. Unlike the Exclusive Gateway, all condition Expressions are evaluated. The true evaluation of one condition Expression does not exclude the evaluation of other condition Expressions.
What is an event based gateway?
The Event-Based Gateway represents a branching point in the Process where the alternative paths that follow the Gateway are based on Events that occur, rather than the evaluation of Expressions using Process data (as with an Exclusive or Inclusive Gateway).
What are a pool and a Swimlane in a BPMN diagram?
In BPMN, swimlane is divided into types, pool and lane. A pool represents a participant who takes part in a process. It is a rectangular container that can contain flow objects vertically or horizontally, such as task and activity. On the other hand, a lane is a graphical sub-division in a pool.
What is the basic form of parallel processing?
There are multiple types of parallel processing, two of the most commonly used types include SIMD and MIMD. SIMD, or single instruction multiple data, is a form of parallel processing in which a computer will have two or more processors follow the same instruction set while each processor handles different data.
How do you show parallel processes in a flowchart?
The horizontal bars with diamonds is found in the flowchart menu. The parallel mode symbol of two horizontal lines is a flowchart notation used to indicate a set of processes that can be done in parallel.
Can BPMN have two starts?
The BPMN standard allows for multiple start and end events to be used at the same process level. There a few reasons why the business analyst may use multiple start or end events, but caution must be used to avoid mistakes.
What is Camunda workflow?
Camunda Platform is an open-source workflow and decision automation platform. Camunda Platform ships with tools for creating workflow and decision models, operating deployed models in production, and allowing users to execute workflow tasks assigned to them.
What are the three types of activities within a process?
The types are Start, End and Intermediate. An event is something that happens during a business process.
What is bidirectional gateway?
In a bidirectional database, helpdesk, or other gateway configuration, changes made to the alerts in a source ObjectServer are replicated in a destination application, and the destination application replicates changes to its alerts in the source ObjectServer.
What is the difference between router and gateway?
A Router is a networking layer system used to manage and forward data packets to computer networks. A gateway is simply a device or hardware that acts as a “gate” between the networks. It could also be defined as a node that acts as an entry for other network nodes.
What is difference between hub and switch?
KEY DIFFERENCES A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.
Is firewall a networking device?
A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. … A firewall can be hardware, software, or both.
What is gate way used for?
A computer that sits between different networks or applications. The gateway converts information, data or other communications from one protocol or format to another. A router may perform some of the functions of a gateway.
Which gateway provides to the network?
If you have a wireless network at home that gives your entire family access to the Internet, your gateway is the modem (or modem-router combo) your ISP provides so you can connect to their network.
What is the gateway that can be used to model complex synchronization behavior?
A Complex Gateway can be used to model complex synchronization behavior. An Activation Condition is the Complex Gateway’s property, which is used to describe precise behavior.
What is sequence flow in BPMN?
A sequence flow is the connector between two elements of a process. After an element is visited during process execution, all outgoing sequence flows are followed. This means that the default nature of BPMN 2.0 is to be parallel: two outgoing sequence flows create two separate, parallel paths of execution.
What is a call activity in BPMN?
A BPMN Call Activity references an Activity defined in a process that is external to the current process definition. It allows you to create a reusable process definition that can be reused in multiple other process definitions.
What is the role of decision gateways in process automation?
Gateways control the flow of a process. They can merge multiple process flows together or split one process flow into multiple process flows when a decision is made in the process.
