DISPATCH-57 - Fixed balanced forwarding so it a) wont involve "full" links, and
b) will honor
the valid-origin for messages when choosing a path to the destination, and c)
uses the router
cost as a threshold for using inter-router links.
> Balance deliveries adaptively across all competing consumers in the network

>
> When there are multiple competing consumers on an address across a network,
> the network should balance deliveries to those consumers adaptively. This
> will cause more messages to be delivered to faster consumers and fewer
> messages to slower consumers.
> The basic idea is that each router tracks the deliveries and can know how
> many outstanding (unacked) deliveries have been sent via each outbound link.
> It can then choose a link based on the smallest number of outstanding
> deliveries. Faster links will tend to have fewer deliveries and will get
> preference in the balancing.
> This feature makes use of the route-cost to remove router nodes. The
> cost-to-remote-consumer is used as a threshold for forwarding deliveries to
> that node. For example, if the cost to a remote consumer is 100, then the
> local router that takes in deliveries to the address will only start
> forwarding messages to the remote node once local consumers have a backlog of
> at least 100 outstanding (unsettled) deliveries.
