This disclosure provides a computer-implemented method. The method may comprise obtaining a character of first-direction communications and a character of second-direction communications in a network environment, the first-direction communications being network communications from a first node to a second node, and the second-direction communications being network communications from the second node to the first node. The method may further comprise determining a dependency between the first node and the second node based on the character of first-direction communications and the character of second-direction communications, the dependency between the first node and the second node indicating whether the first node depends on the second node or the second node depends on the first node.

Dependency determination in network environment

Embodiments of the present disclosure relate to methods, systems, and computer program products for managing a distributed system. In one embodiment, a computer-implemented method is disclosed. In the method, packets that are to be transmitted among a group of nodes in a distributed system may be collected into a queue of packets, here a packet in the queue is associated with a source node and a destination node in the group of nodes. A snapshot in the group of snapshots may be obtained from a node in the group of nodes, therefore a group of snapshots may be obtained from the group of nodes. A snapshot of the distributed system may be generated based on the queue of packets and the group of snapshots. In other embodiments, a computer-implemented system and a computer program product for managing a distributed system are disclosed.
