== 9/17/2013 == * Shrikanth presented a comparison across 3 prominent !OpenFlow controllers: [http://www.opendaylight.org/ OpenDaylight], Floodlight, and [http://osrg.github.io/ryu/ 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 [http://www.alexa.com/topsites 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 == 9/24/2013 == * Yi presented the city/PoP based network topology * Ray suggested the geo-distance based network topology model would be a useful full length talk * Could also get Jim Kurose's input on the model * Next steps include modifying GNRS simulation for locality and adopting the above PoP model * Chao presented slides summarizing EIR - maybe from reading the paper? * Ray: look at messaging protocol incl. message fields in implementation for correctness and completeness * Ray: look to implement active fine-grain (per-client) protocol to query link/path quality at the edge to decide among multiple paths * Need to address reviewer doubts whether inter-domain is the right place to address issues at the edge * Francesco presented an update on the host stack implementation and demo plans for GEC-18 * Stack and API code restructured for cleaner layering - e.g., pluggable alternate transport * API reflects basic ops defined in MobiArch paper - missing 'get', content and service ops * Demo at NYU poly will be a breadcrumb or geo-tagged message drop app * Ray/Akash suggest that the use of QR codes for geo-tagging (location to GUID) could be confusing - need further discussion on appropriate fine-grain geo-tagging
