Abstract: Techniques for a hub node, provisioned in a site of a hub and spoke overlay network, to receive, store, and/or forward network routing information associated with a spoke, and send packets directly to spoke(s) that are remote from the hub node. A first hub node may receive a network advertisement including a border gateway protocol (BGP) large community string from a first spoke local to the first hub node. The first hub node may send the BGP large community string to a second hub node remote from the first hub node. The second hub node may decode network routing information from the BGP large community string and store the network routing information locally. The second hub node may send a packet from a second spoke local to the second hub node directly to the first spoke without the data packet being routed via the first hub node.

Abstract: The invention relates to a method of processing data frames arriving on a network interface, comprising the following steps implemented in the network interface: storing a set of target positions (tgtPOS), positions in a frame at which are expected at least one parameter characterizing a subframe (ETH_TYPE) and parameters (SRC_IP, DST_IP) characterizing a client-server session; storing an expected value (xpVAL) for the subframe parameter; receiving a current frame and comparing the value (xtVAL) received at the position of the subframe parameter to the expected value; if equal, calculating an index (IDX) from the values received at the positions of the session parameters; and routing the current frame to a processing resource associated with the index.
