Techniques are disclosed for configuring a physical computing system (e.g., in a cloud computing network) to connect a network bond with a virtual multilayer switch. An operating system process executing in the physical computing system receives a selection of one or more network interfaces. The process aggregates the selected network interfaces into a bonded network interface having a first port. The process creates a network bridge having a second port. The process associates the first port with the second port. The process connects the network bridge with an integration bridge of the virtual multilayer switch via the second port.

A process for selecting a least weight path between two nodes in a data communication network uses partial trees created and cached in prior route selection operations. All root nodes on possible paths between the two nodes are identified. Any cached tree having a root matching one of the identified root nodes is retrieved from storage. If necessary, each retrieved tree is extended until it includes all possible destination nodes. The extended and/or retrieved trees are used to select the least weight path between the two nodes. The extended tree is then cached for possible use in future route selection operations.

A method and apparatus for interconnecting multiple data processing networks, each data processing network including: multiple network nodes having routing and functional capability within a data processing network; and, multiple endpoint nodes, each including only local address capability. Each network node may be connected to multiple endpoint nodes and other network nodes; however, connection is only permitted to network nodes within the same data processing network. A border node is established for interconnection between two data processing networks. The border node includes a network node interface having routing and functional capability within a first data processing network and an endpoint node interface having local address capability. When interconnected between the first data processing network and a network node within a second data processing network, the border node emulates a network node within the first data processing network while appearing as an endpoint node within the second data processing network, permitting full connectivity between the two networks. The border node then maintains routing information for communication between the two data processing networks in two segments. A first segment details the route between the first data processing network and the border node while a second segment details the route between the border node and a node within the second data processing network.
