1. A method of configuring a set of conversation identifiers (IDs) at a network device in a link aggregation group, wherein each conversation ID is to identify a conversation, wherein the network device and a neighbor network device are included in a portal of the link aggregation group, and wherein each of the network device and the neighbor network device includes an aggregator and a gateway of the portal, the method comprising:

  • initializing the set of conversation IDs at the network device, wherein the initialization includes setting entries of a Boolean vector associated with the set of conversation IDs to be a sequence of zeroes, and wherein the Boolean vector includes values indicating processing the set of conversation IDs through the gateway or the aggregator of the network device;

    determining that distribution of the set of conversation IDs is in need of update;

    setting a variable indicating that the distribution of the set of conversation IDs is in need of update; and

    setting values of an operational vector indexed by the conversation IDs, wherein the operational vector lists which network device of the portal processes each of the set of conversation IDs.
