- All Implemented Interfaces:
- LogicalLink.Receiver
- public class WANPIPE
- extends Protocol
- implements LogicalLink.Receiver
Logical point-to-point link. Uses multiple physical links to provide a reliable transport. For example,
if there are 2 physical links over different networks, and one of them fails, the WAN pipe will still be
able to send traffic over the other link. Currently traffic is sent over the physical links round-robin,
but this will be made configurable in the future. Example: 70% over first link, 30% over second, or
packets are split and sent across both links (increasing the available bandwidth).

- Description copied from class:
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()
.
