Claim 0:
1. A method for managing a system topology of a distributed computing system comprising:
providing a network of clusters with at least a first cluster and a second cluster;
establishing a connection between all clusters from the network of clusters, which for the first and second cluster comprises: for each node of the first cluster, establishing a single outbound connection to a select node of the second cluster; and
managing communication over the system topology between different pairs of origin nodes and receiver nodes of different clusters with dynamic switching between optimistic mode and interest only mode based on traffic volume and interest between pairs of the different clusters, comprising:
at an origin node of the first cluster when in the optimistic mode, transmitting all communications over the connection except interests corresponding to an unfollow-type subscription interest;
at a receiver node of the second cluster when in the optimistic mode, in response to receiving an optimistically received communication from the origin node when there is no interest within the nodes of the second cluster, communicating an unfollow-type subscription interest to the origin node;
at the receiver node of the second cluster when in the interest only mode, communicating a follow-type subscription interest to the origin node;
at the origin node of the first cluster when in the interest only mode, transmitting only communications that correspond to an interest expressed in the follow-type subscription interest.
