Abstract:
1. An apparatus comprising: a first network interface to receive packets from a local wireline network using a packet filter component that only passes multicast packets with a particular time-to-live (TTL) parameter value destined for a node on a wireless network; a duplicate component that duplicates packets that pass through the packet filter component; a packet delay component to delay packets received from the local wireline network and provides a varying amount of delay to different packets, and comprises a network emulator having a quality of service (QoS) component to delay and jitter the packets in time; a component to modify the TTL parameter value to a known value, of the delayed packets to prevent further reception and duplication; and a second network interface to transmit the delayed packets onto the local wireline network as duplicate packets to effect forward error correction through duplicate, delay, and spread (DDS) of multicast packets destined for the node on the wireless network.
