Topo2: Refactored NavigateToRegion events

There was duplicated logic in Topo2Breadcrumb|SubRegion|PeerRegion. This has been refactored out so
all the logic for navigating to a new region is handled in a single place (Topo2RegionNavigationService).

Topo2RegionNavigationService is a pub/sub class. There are two reasons for this choice;
1. Topo2Layout needs to create the new force layout simulation for the region that is about to enter.   Then it creates a transition between the old and new.
2. This will allow application developers to hook into the region:navigation event incase they need
   to update the topology for the new region displayed.

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.
