The present invention relates to several techniques for managing the contents of proxy tables in ways that optimize performance, latency, and reliability for communication networks, while ensuring a certain number of early-acting proxies per restricted device. An entity is allowed to keep a required number of proxies per resource-restricted device by removing or adding proxy table entries. Furthermore, the entity is allowed to keep track of early-acting proxies based on forwarding strategies, reporting strategies and/or polling strategies. Thereby, proxy table entries can be controlled to optimize overall system performance and reliability characteristics.
