Abstract: A method for reducing the number of IP addresses used by VRRP includes creating a VRRP control packet at a router of a plurality of physical routers configured in parallel in a data pathway. The physical routers are configured as a virtual router and the VRRP control packet is configured as an IPv6 control packet. The method includes inserting an IP address of the virtual router in a router address field of a control packet header. The IP address is formatted as an IPv4 address. The method includes inserting, in a reserved field of the control packet, a first value. The first value differs from a default value for the reserved field signifying that IP addresses in the router address field are formatted as IPv6 addresses for IPv6 control packets and the first value signifies that the IP addresses in the router address field are formatted as IPv4 addresses.

Abstract: The predictive overlay network architecture of the present invention improves the performance of applications distributing digital content among nodes of an underlying network such as the Internet by establishing and reconfiguring overlay network topologies over which associated content items are distributed. The present invention addresses not only frequently changing network congestion, but also interdependencies among nodes and links of prospective overlay network topologies. The present invention provides a prediction engine that monitors metrics and predicts the relay capacity of individual nodes and links (as well as demand of destination nodes) over time to reflect the extent to which the relaying of content among the nodes of an overlay network will be impacted by (current or future) underlying network congestion.
