SERVER NODE DISCOVERY MECHANISM APPLIED IN CLOUD ENVIONMENT CAPABLE OF SEARCHING SERVER NODE WITHIN CLOUD SERVICE CLUSTER

摘要

A packet sending node is employed in a network segment. The packet sending node includes a packet storage module, a packet sending module and a packet accepting module. The packet storage module is configured to store an encryption packet including a network address of the packet sending node. The packet sending module is configured to send the encryption packet to a packet receiving node in the network segment based on the user datagram protocol. The packet accepting module is configured to receive a response packet sent by the packet receiving node according to the network address of the packet sending node in the encryption packet. A server node discovery mechanism and a packet receiving module are also provided.
