    Abstract: A method of improving BGP convergence in a packet-switched network comprises receiving, at a router in the packet-switched network, an advertisement of a first route that includes alternate route information indicating that an alternate route is available; storing the alternate route information in association with the first route; detecting a change in network reachability of the first route, and in response thereto, determining if the alternate route information is stored for the first route, and if so: awaiting, for a particular time, an advertisement of an alternate route; storing and using the alternate route in place of the first route.

    Abstract: Approaches are disclosed for switching transport protocol connection keys. In a transport protocol module configured to use a first key for signing messages associated with a transport protocol connection, a second key is configured for the transport protocol connection. A first message that is associated with the transport protocol connection is received. The first message includes a first signature. A first and a second message digests are computed for the first message, where the first message digest is based on the first key and the second message digest is based on the second key. The first message is validated if the first signature in the first message matches any one of the first message digest and the second message digest.

    Abstract: A method, apparatus and computer program product for scaling hierarchical route reflectors (RRs) using automated Outbound Route Filtering (ORF) is presented. A first route reflector identifies other route reflectors configured as Route reflector clients within a route reflector hierarchy. The first route reflector then builds a common set of route target filters received from the client route reflectors and sends the common set of route target filters to client route reflectors.
