org.jgroups.protocols.HTOTAL
- public class HTOTAL
- extends org.jgroups.stack.Protocol
Implementation of UTO-TCP as designed by EPFL. Implements chaining algorithm: each sender sends the message
to a coordinator who then forwards it to its neighbor on the right, who then forwards it to its neighbor to the right
etc.

- Description copied from class:
org.jgroups.stack.Protocol
- Configures the protocol initially. A configuration string consists of name=value
items, separated by a ';' (semicolon), e.g.:
"loopback=false;unicast_inport=4444"
down
public void down(org.jgroups.Event evt)
- Description copied from class:
org.jgroups.stack.Protocol
- An event is to be sent down the stack. The layer may want to examine its type and perform
some action on it, depending on the event's type. If the event is a message MSG, then
the layer may need to add a header to it (or do nothing at all) before sending it down
the stack using
passDown(). In case of a GET_ADDRESS event (which tries to
retrieve the stack's address from one of the bottom layers), the layer may need to send
a new response event back up the stack using passUp().
up
public void up(org.jgroups.Event evt)
- Description copied from class:
org.jgroups.stack.Protocol
- An event was received from the layer below. Usually the current layer will want to examine
the event type and - depending on its type - perform some computation
(e.g. removing headers from a MSG event type, or updating the internal membership list
when receiving a VIEW_CHANGE event).
Finally the event is either a) discarded, or b) an event is sent down
the stack using
passDown() or c) the event (or another event) is sent up
the stack using passUp().
forwardTo
private void forwardTo(org.jgroups.Address destination,
org.jgroups.Message msg)
determineCoordinatorAndNextMember
private void determineCoordinatorAndNextMember(org.jgroups.View v)
