Abstract: In order to facilitate efficient and scalable lookup of current hop limits of transmitted packets, a communications device embeds hop limit values along with other connection parameters in a connection data structure. To transmit a packet for a particular connection, the communications device retrieves the data structure for the particular connection and applies the hop limit value embedded in the data structure to the packet for transmission. To keep track of the hop limits being embedded in different data structures of different connections, the communications device use a binary search in which each node of the search tree correspond to a different connection. The communications device maintains one such search tree per communications interface.
