Method Detail

processInternalRequest

public void processInternalRequest(javax.sip.message.Request request)

Specified by:

processInternalRequest in interface BalancerAlgorithm

Overrides:

processInternalRequest in class DefaultBalancerAlgorithm

processInternalResponse

public void processInternalResponse(javax.sip.message.Response request)

Specified by:

processInternalResponse in interface BalancerAlgorithm

Overrides:

processInternalResponse in class DefaultBalancerAlgorithm

processExternalResponse

public void processExternalResponse(javax.sip.message.Response request)

Description copied from interface: BalancerAlgorithm

Allow algorithms to process responses

Specified by:

processExternalResponse in interface BalancerAlgorithm

Overrides:

processExternalResponse in class DefaultBalancerAlgorithm

processExternalRequest

public SIPNode processExternalRequest(javax.sip.message.Request request)

Description copied from interface: BalancerAlgorithm

When a request comes it is passed to the algorithm. The algorithm must add the Route headers to the node or nodes where the request should go. The actual proxying is done at the LB. Allowing the algorithm to add headers allows more flexibility for example when you need to pass some information to the AS or the application to make further LB decisions or multiprotocol cooperative load balancing. It is very little effort for great flexibility.

Returns:

init

public void init()

Description copied from interface: BalancerAlgorithm

Lifecycle method. Notifies the algorithm when it's initialized with properties and balancer context.

assignToNode

public void assignToNode(java.lang.String id,
                         SIPNode node)

Description copied from interface: BalancerAlgorithm

Assign callid to node

Specified by:

assignToNode in interface BalancerAlgorithm

Overrides:

assignToNode in class DefaultBalancerAlgorithm

jvmRouteSwitchover

public void jvmRouteSwitchover(java.lang.String fromJvmRoute,
                               java.lang.String toJvmRoute)

Description copied from interface: BalancerAlgorithm

Move load from one node to another to follow mod_jk/mod_cluster

Specified by:

jvmRouteSwitchover in interface BalancerAlgorithm

Overrides:

jvmRouteSwitchover in class DefaultBalancerAlgorithm
