Software Defined Networks 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~ 引用[1]

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 • 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 • 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
Meridian Implementation How it works?

For Any cloud-based applications. G1{web1,web2} G2{APP1,APP2} G3{db1,db2} {G1,G2,LB} {G2,G3,bandwidth} {APP1,APP2,SPF} {db1,db2,broadcast}
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.
Future work • Performance • Recovery failed plans
