• Shrikanth presented a comparison across 3 prominent OpenFlow controllers: ​OpenDaylight, Floodlight, and ​RYU
  • Only Floodlight doesn't support OF version 1.3 (ipv6, MPLS, multiple flow tables). Other differences minor. Programming effort not very different(?) Since RYU is python and other 2 are Java-based, migrating current MF controller code (Java) is simpler mirgating to OpenDaylight.
  • Shrikanth will clarify if MF header matching is better served any better by v1.3
• Sugang presented a summary of MF design for M2M application domain and implementation for sensor data dissemination to subscribers using mobile phone gateways
  • Outstanding items include:
• Yi presented evaluation of locality-aware scheme enhancements to GNRS
  • goal: establish a geo model to map routers/PoPs/networks, requests, mobility events to specific geo-location
  • will use a path-inflation parameter to determine routing latencies between geo-locations
  • Rocketfuel data used to establish AS-to-geolocation, inter-AS latencies (or inter-pop), and intra AS distances
  • Presented GNRS query and update models extracted from ​Alexa popularity index data and vehicular mobility traces
• Feixiong presented MF content approach using GNRS with some focus on edge-caching
  • Ray points out exploring mobile edge caching - small-cell caching - may be interesting
  • CDN requests data will be useful for evaluation - Ray might check with Akamai
