Fix for ONOS-3183

Stream processes by Lambda queries in collection objects has a known performance bottleneck. For each create and update link data operations, this  kind of queries are frequently used and this causes inefficient topology discovery operation. For to solve that problem i analize thread dump during discovery process and i saw that especially getAllProviders method uses high cpu. than i change the provider search operation with additional map data which holds linkkey and its providers. by this way provider search operation not only gets faster but also uses minimum resource. Before that change, i can discover only 4XX number of switches at one controller, but later number grows to 15XX switches

ONOS : Open Network Operating System

What is ONOS?

ONOS is a new SDN network operating system designed for high availability, performance, scale-out.

Top-Level Features

  • High availability through clustering and distributed state management.
  • Scalability through clustering and sharding of network device control.
  • Performance that is good for a first release, and which has an architecture that will continue to support improvements.
  • Northbound abstractions for a global network view, network graph, and application intents.
  • Pluggable southbound for support of OpenFlow and new or legacy protocols.
  • Graphical user interface to view multi-layer topologies and inspect elements of the topology.
  • REST API for access to Northbound abstractions as well as CLI commands.
  • CLI for debugging.
  • Support for both proactive and reactive flow setup.
  • SDN-IP application to support interworking with traditional IP networks controlled by distributed routing protocols such as BGP.
  • IP-Optical use case demonstration.
