In the method, a transmission data unit is transmitted from the source node to the proxy node and to the other nodes. A confirmation is selectively transmitted from the proxy node to the other nodes based on whether a reception data unit corresponding to the transmission data unit is correctly received at the proxy node. Based on whether the confirmation is received at one of the other nodes, a negative acknowledgement is selectively transmitted from the one of the other nodes to the source node. Other methods and devices are also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Network retransmission protocols using a proxy node","description":"One embodiment relates to a method for communicating over a transmission medium shared between a plurality of nodes including a source node, a proxy node, and other nodes.
