我系統都寫好也測試好了可以麻煩你幫我正式佈署上線嘛?

OK~ 我已經幫你灌了 5個在機架上 ,系統參數都設定好,也幫你把DB都灌好了,等下就幫你把程式佈署上去~

喔對了系統會需要用到 8080,63382,3233...port,然後會必須要…….

沒問題~我已經幫你把Juniper 的VPN Gateway 連線設好了

喔這個等下你直接跟NAdmin講,網路設定是由他們負責的~

ok~這簡單Security Group 我已經幫你開這幾個Port了…..blablabla

ALL INONE

abstract api layer
Abstract API layer
  • Present application with a network model
  • Associated APIs that expose only the information needed to interact with the network
  • Logical view of the network using high-level APIs.
network orchestration platform
Network Orchestration platform
  • Logical-to-physical translation of commands issued through the abstraction layer
  • Convert API calls into the appropriate series of commands on the underlying network
  • Network-wide service to application.
  • Global annotated view of the data center topology for applications
  • Different routing algorithms
  • Planner module that can schedule network configuration

or control task

network driver layer
Network driver layer
  • Consists of plug-in or drivers enable the controller to interface with various network technologies or tools.
  • The orchestration layer uses these drivers to issue commands on specific devices or collect information from the network.
  • Implemented a logical driver that interfaces to OpenFlow devices
  • Drivers to enable virtual network creation
  • Topology data gathered

summary
Summary
  • Meridain, an SDN-based controller framework for cloud networking.
  • A network service model for users to construct and manage logical topologies for their complex workloads.
  • Current system is only an initial prototype.
