摘要： To reduce the dependency of overlay networks on underlay networks to route messages, a virtual ring routing architecture may be formed that leverages the design of the overlay network to achieve their desirable scaling and robustness properties but also reduce the dependency on any underlay network to setup and maintain connectivity. More particularly, each node may have a single, fixed, location independent node identifier, to organize the nodes into a virtual ring. The connectivity between nodes through the actual network topology may be formed by a plurality of nodes in the virtual ring by maintaining connectivity to those nodes identified as virtual neighbor nodes within the virtual ring. The path segments defining communication connections between virtual neighbor nodes may be used to route messages between any pair of nodes in the network and may reduce route discovery overhead, reduce delay in transmission, and reduce or eliminate flooding to setup or maintain the path segments.

摘要： A method for optimized route caching includes comparing a destination address of a network packet to a first set of prefixes in a routing cache, and comparing the destination address to a second set of prefixes in a full routing table when a longest matching prefix for the destination address is not found in the routing cache. The method further includes copying the longest matching prefix and a set of sub-prefixes of the longest matching prefix from the full routing table to the routing cache, and forwarding the network packet.

摘要： A system is provided for migrating a VM over a WAN. A first server has a VM. The first and second servers are operatively connected over the WAN by a virtual private local area network service. The first server migrates the VM to the second server by coping files and state of the VM to the second server without interrupting the interactive software on the VM. During a last round of migrating the VM, for packets intended for the VM on the first server, the first server buffers the packets in a buffer as buffered packets. Instead of delivering the buffered packets to the VM, the first server transmits the buffered packets to the second server. The second server plays the buffered packets to the VM migrated to and operating on the second server, such that buffered packets are played before current packets currently received from the clients are played.
