Scalable Network Configuration with Consistent Updates in Software Defined Networks |
摘要 |
Mechanisms are provided for configuring a data flow between a source device and a destination device in a network. The mechanisms receive, from a network control application, a request to establish a network configuration corresponding to a data flow between the source device and the destination device. The request comprises a fine grained header field tuple for defining the data flow. The mechanisms allocate, from a shadow address pool, a shadow address to be mapped to the fine grained header field tuple. The shadow address pool comprises addresses not being used by devices coupled to the network. The mechanisms configure a network infrastructure of the network to route data packets of the data flow from the source device to the destination device based on the shadow address. |

1. A method, in a data processing system comprising a processor and a memory, for configuring a portion of network corresponding to a data flow between a source device and a destination device in a network, the method comprising:
receiving, from a network control application, a request to establish a network configuration corresponding to a data flow between the source device and the destination device, wherein the request comprises a fine grained header field tuple for defining the data flow; allocating, from a shadow address pool, a shadow address to be mapped to the fine grained header field tuple, wherein the shadow address pool comprises addresses not being used by devices coupled to the network; and configuring a network infrastructure of the network to route data packets of the data flow from the source device to the destination device based on the shadow address. |
