US10855609B2	Interconnect and method of operation of such an interconnect An interconnect is provided that has a plurality of nodes, and a ring network to which each of the nodes is connected to allow packets to be transmitted between nodes. For an ordered sequence of packets one of the nodes is arranged as a source node to add each packet of the ordered sequence on to the ring network, and another of the nodes is arranged as a destination node to remove each packet of the ordered sequence from the ring network. The source node is enabled to add a packet of the ordered sequence on to the ring network without waiting for a previously added packet of the ordered sequence to be removed from the ring network by the destination node. When the destination node is unable to accept a given packet of the ordered sequence that is currently being presented to the destination node by the ring network, that given packet remains on the ring network and continues to be transmitted around the ring network such that after a respin period that given packet will be presented again to the destination node. The destination node is then arranged to prevent acceptance of at least any other packets of the ordered sequence subsequently presented to the destination node by the ring network until the destination node has accepted the given packet following at least one respin period. This can improve the efficiency of the ring network in the handling of ordered sequences of packets, whilst still ensuring the ordering constraints are met.

US10855580B2	Consistent route announcements among redundant controllers in global network access point Systems and methods are described to enable management of redundant route announcements in an access point including multiple packet processors. Route controllers are described that can generate routing information distributing incoming packets to the access point among the packet processors. The route controllers can operate redundantly, such that a failure of a single controller does not cause a complete failure of the access point. To avoid different announcements by different route controllers (particularly under partial failure scenarios), the route controllers utilize a strongly consistent data store to store routing information. So long as a record within the data store contains valid information, it is considered authoritative and routing information from the record is announced by all route controllers. If the information is invalid, the route controllers attempt to overwrite the information with new, higher priority routing information. A single write succeeds, resulting in new authoritative routing information.
