Interface ProtectionConfigBehaviour

All Superinterfaces:

@Beta
public interface ProtectionConfigBehaviour
extends HandlerBehaviour

Behaviour for configuring Device triggered protection mechanism.

Protected transport entity model

 
 - ProtectedTransportEndpoint
    +- TransportEndpoint - working transport entity/path
    |
    +- TransportEndpoint - standby transport entity/path
    ⋮
 
 

ProtectedTransportEndpoint is the entity representing the transport entity endpoint. Traffic flowing into the protected transport endpoint will flow through one of it's underlying TransportEndpoint, (=active transport entity). After successful creation of ProtectedPathEndpoint, implementation is expected to advertise virtual Port corresponding to the ProtectedPathEndpoint created.

Method Detail

createProtectionEndpoint

CompletableFuture<ConnectPoint> createProtectionEndpoint(ProtectedTransportEndpointDescription configuration)

Creates protected path endpoint.

Parameters:

configuration - ProtectedTransportEndpointDescription

Returns:

ConnectPoint for the virtual Port added on success, or exceptionally return ProtectionException as cause on error.

updateProtectionEndpoint

CompletableFuture<ConnectPoint> updateProtectionEndpoint(ConnectPoint identifier,
                                                         ProtectedTransportEndpointDescription configuration)

Updates protected path endpoint configuration.

Parameters:

identifier - ConnectPoint for the virtual Port representing protected path endpoint

configuration - ProtectedTransportEndpointDescription

Returns:

identifier on success, or exceptionally return ProtectionException as cause on error.

deleteProtectionEndpoint

CompletableFuture<Boolean> deleteProtectionEndpoint(ConnectPoint identifier)

Deletes protected path endpoint.

Parameters:

identifier - ConnectPoint for the virtual Port representing protected path endpoint

Returns:

true if successfully removed, false otherwise.

getProtectionEndpointConfigs

CompletableFuture<Map<ConnectPoint,ProtectedTransportEndpointDescription>> getProtectionEndpointConfigs()

Retrieves ProtectedTransportEndpointDescriptions on the Device.

Returns:

ProtectedTransportEndpointDescriptions on the Device

getProtectionEndpointConfig

default CompletableFuture<ProtectedTransportEndpointDescription> getProtectionEndpointConfig(ConnectPoint identifier)

Retrieves ProtectedTransportEndpointDescription with specified ID.

Parameters:

identifier - ConnectPoint for the virtual Port representing protected path endpoint to retrieve

Returns:

ProtectedTransportEndpointDescription found or null

getProtectionEndpointStates

CompletableFuture<Map<ConnectPoint,ProtectedTransportEndpointState>> getProtectionEndpointStates()

Retrieves ProtectedTransportEndpointStates on the Device.

Returns:

ProtectedTransportEndpointStates on the Device

getProtectionEndpointState

default CompletableFuture<ProtectedTransportEndpointState> getProtectionEndpointState(ConnectPoint identifier)

Retrieves ProtectedTransportEndpointState on the Device.

Parameters:

identifier - ConnectPoint for the virtual Port representing protected path endpoint to retrieve

Returns:

ProtectedTransportEndpointState found or null

getProtectionEndpoint

default CompletableFuture<Map.Entry<ConnectPoint,ProtectedTransportEndpointState>> getProtectionEndpoint(String fingerprint)

Retrieves ProtectedTansportEndpoint information (=virtual Port ConnectPoint and ProtectedTransportEndpointState pair) on the Device.

Parameters:

fingerprint - of the protected path endpoint to retrieve

Returns:

ProtectedTansportEndpoint information found or null

switchToForce

default CompletableFuture<Void> switchToForce(ConnectPoint identifier,
                                              int index)

Attempts to forcibly switch to the one specified path by index.

Parameters:

identifier - ConnectPoint for the virtual Port representing protected path endpoint

index - path index to switch to

Returns:

Completes if request was accepted, fails exceptionally on error. Note: completion does not always assure working path has switched.

switchToManual

CompletableFuture<Void> switchToManual(ConnectPoint identifier,
                                       int index)

Attempts to manually switch to the one specified path by index. This operation would be rejected if the specified path is a fault path.

Parameters:

identifier - ConnectPoint for the virtual Port representing protected path endpoint

index - path index to switch to

Returns:

Completes if request was accepted, fails exceptionally on error. Note: completion does not always assure working path has switched.

switchToAutomatic

default CompletableFuture<Void> switchToAutomatic(ConnectPoint identifier)

Attempts to set the device to automatic protection mode.

Parameters:

identifier - ConnectPoint for the virtual Port representing protected path endpoint

Returns:

Completes if request was accepted, fails exceptionally on error.
