20170310574 | COMPILER FOR AND METHOD OF SOFTWARE DEFINED NETWORKING, STORAGE AND COMPUTE DETERMINING PHYSICAL AND VIRTUAL RESOURCES - Method of and a compiler for controlling a network based on a logical network model. The compiler determines physical and/or virtual resources, comprising of physical nodes and physical links, against which the logical model can be compiled. The network has known physical nodes, unknown physical nodes and logical nodes. The known physical nodes are “physical nodes” which are existing or still to be setup (virtual) nodes in the network. The known physical nodes are interconnected by physical links in accordance with a physical network layout. The logical network model has logical nodes indicated with a logical node name which refers to at least one known physical node or one unknown physical node in the network. The method uses a depth-mapping relation defining how the logical nodes are mapped to the known physical nodes and the unknown physical nodes. The term “unknown physical node” is used to define an imaginary physical node to which logical nodes can be mapped through depth-mappings and which are to be substituted by a physical node of the network of which the physical node name is stored. The method includes creating logical links between the logical nodes in dependence on the paths between the known physical nodes and/or the unknown physical nodes and on the depth-mapping relation. Known physical nodes are determined for unknown physical nodes and known physical paths are determined for unknown physical paths between unknown physical nodes by performing a search. The method uses edge-relationships between logical link, logical path, physical link, physical path and depth-mapping relations. Logical paths in the logical network are transformed into a physical path comprising of physical links between the physical nodes through recursive calculation and forwarding instructions are created for the physical nodes, in dependence on the edge-relationships and point-of-attachment names between physical links and physical nodes. | 2017-10-26 |

According to the hostname, a first IP address that addresses a server identified by the hostname is determined. A second IP address is also determined as the second IP address of the specific network service. Finally, a message is sent to the user's network that specifically instructs the user's network to route data addressed to the first IP address to the second IP address. The message causes configuration of a router on the user's network to route data on the first network service. System and computer program product embodiments are also disclosed. | 2017-10-26 |
