41 What is Managed & Dynamic Connectivity? Merging of software control with optical switching and intelligent ID technology for the management of physical layer networks: Managed means all the optical devices and connections are fully discoverable by the software overseeing the network Managed also means that changes to the network are tracked automatically and documented by the software Dynamic means that point-to-point fiber connection can be instantly connected to any other point in the network through the use of optical hardware and software commands Dynamic also means that the network can be configured to allow built-in tap monitoring of ports and other features such as broadcasting and network provisioning and sequestering 42

45 The Evolution to Managed & Dynamic Physical Layer Connectivity Applications are purpose built solutions that deliver analysis and results to businesses. Communications networks provide reachability to applications. Software control and SDN increase agility and scalability by making the network MANAGED and DYNAMIC: MANAGED network hardware and topology are controlled & discovered via software in real time. DYNAMIC network configurations and reachability can be changed at will via software as needed. Physical layer copper and fiber provides the fundamental connectivity for network switching devices Current solutions are MANUAL and SLOW to change. MANAGED physical layer provides autodiscovery of accurate, real-time physical topology. DYNAMIC physical layer enables software-controlled connectivity reconfiguration and MACs. 46

49 Security & Diagnostics with built-in monitoring & tap Server Server Switch Server Diagnostics There are many use cases for data tap in a network Software automatically discovers the network Troubleshoot for application level issues Every server, switch, router connection is documented Take any server off line or to a dev. Network real-time Point & click data stream in a copy is made non-intrusively and the copied data is delivered to diagnostic servers Instantly quarantine a suspect machine Note: for automated monitor/tap, Layer 1 Switch Features are required in the network. 50

50 Operations & Maintenance with software management The business of running of a data center network operations is very involved. Dynamic and Managed networks are designed to ease day to day operational challenges. Network planning personnel can plan the network in software, OFF-LINE The software then helps the installation process and keeps the documentation of the network current at all times When network ops creates a ticket to move a server from one switch port to another, the system takes over The software system can guide technicians to perform the work. At one level the system can even make the required changes, that s a DYNAMIC solution. 51

51 Pulling it all together.. Installing a software-based Managed & Dynamic Network provides a more flexible and intuitive way to manage a Data Center The network can reside in parallel with the existing network without the need to replace the existing infrastructure Additional benefits of seamless built-in tap monitoring and connectivity tracking are available 52
