Session B: How do we manage heterogeneous networks including those at the tactical edge ?

1. Network Management Interoperability Technical Exchange Session B: How do we manage heterogeneous networks including those at the tactical edge? Session Facilitator: Bruce Patterson Principal Network Systems Engineer MITRE 1 1

2. Network Management Interoperability Technical Exchange • Breakout Session B: How do we manage heterogeneous networks including those at the tactical edge (*disadvantaged users)? • What are the middleware requirements to make all of this come together? • Is true multi-vendor interoperability attainable? If so to what degree? • What is the impact in limited bandwidth and dynamic tactical networks? Do different rules need to apply there? • Who controls and enforces service level agreements and monitors performance metrics? • What are industry best practices for managing heterogeneous networks, that could also be adopted by the DoD? 2

3. Network Management Interoperability Technical Exchange • Breakout Session B: How do we manage heterogeneous networks including those at the tactical edge (*disadvantaged users)? • What are the middleware requirements to make all of this come together? • Inputs: • Service Management vs Element Management vs. Resource Management • Standards identification – SOA? • QOS Management Profile – may be different on different networks • Identification of critical/relevant info to the right end point based on available network capacity and type of user/type of equipment available (DIL User) • Manager of manager vs. manger of elements – what does the NMS need to be? • Common situational awareness capability incorporating a tactical and enterprise cross-domain solution 3

4. Network Management Interoperability Technical Exchange • Breakout Session B: How do we manage heterogeneous networks including those at the tactical edge (*disadvantaged users)? • Is true multi-vendor interoperability attainable? If so to what degree? • Inputs: • Central authority guiding common standards and context in which those standards are intended to be used • Ontology as the context • Enforcement? • Acquisition community involvement • Tools come and go, so some level of multi-vendor interoperability will be necessary – already happing on some levels • Provisioning and activation more difficult than gathering information • How to include processes that will never be automated? • Financial incentive to DoD specific application development? 4

5. Network Management Interoperability Technical Exchange • Breakout Session B: How do we manage heterogeneous networks including those at the tactical edge (*disadvantaged users)? • What is the impact in limited bandwidth and dynamic tactical networks? Do different rules need to apply there? • Inputs: • Complete information on network is not always available • Bandwidth • Latency • Intermittent connectivity • Minimize the amount of information required to traverse the network depending on availability, bandwidth, etc. • Self-healing capabilities • How do you know the configuration when rejoining after being disconnected? • How to tailor the views depending on the echelon/user requirements • Network nodes are mobile • Event based reconfiguration • End-to-end visibility of assets 5

6. Network Management Interoperability Technical Exchange • Breakout Session B: How do we manage heterogeneous networks including those at the tactical edge (*disadvantaged users)? • Who controls and enforces service level agreements and monitors performance metrics? • Inputs: • SLA contractual obligations don’t apply to military model in the same way – or at all • SLAs will be different as network capabilities vary • Is a military “SLA” really an expectation of service to meet mission requirements? • End-to-end SLA may be different from a single service/interim service provider – coordination required at different levels to provision, operate and deactivate, ensure spectrum available • Using performance metrics to monitor SLAs • Can they be enforced in the DoDtactical environment? 6

7. Network Management Interoperability Technical Exchange • Breakout Session B: How do we manage heterogeneous networks including those at the tactical edge (*disadvantaged users)? • What are industry best practices for managing heterogeneous networks, that could also be adopted by the DoD? • Inputs: • TM Forum • ITIL • OPNET type simulations • SNMP, WMI, NetFlow, etc. • Better configuration control • Some companies merge, but maintain autonomy in NM operation. Different DoD entities may have valid reasons as well in separate, but interoperable systems • Ontology development • Participation in standards bodies • Security standards 7
