Abstract
According to an aspect of an embodiment, a method of managing packets in a communication network including multiple communication nodes is described. The method may include receiving a packet including a packet header. The packet header may include a packet identifier uniquely identifying the packet. The method may also include determining a packet type of the packet received by a first communication node based on the packet identifier. The method may also include dropping the packet when the packet is determined to be a duplicate packet or routing the packet to a neighbor communication node in a manner that prevents the packet from being caught in a loop when the packet is determined to be a returned packet or a new packet.
