architecture
network management

the platform management system enables operators manage on-board network elements. interfaces , interoperates airborne network management system enable operators manage remote network elements in airborne network. network management system monitors health of network passively testing network faults , latency. system actively troubleshoot faults probes identify , isolate faulty connections, , enables operators apply network parameters , security changes systems based on status of network.


routing/switching

routing , switching enables data dynamically transmitted on network other nodes. routing protocols must able identify nodes transmitted within own platform , data sent other platforms regardless of current topology. routing protocol must provide seamless roaming ensuring no routed packets lost when node changes point of attachment network. maintaining scalability important in routing network changing. network must able function numerous levels of platforms, varying numbers of fast moving platforms, , varying amounts of traffic per platform. routers , switches use metrics determine best paths take when routing data. routing protocol utilized an adaptive quality of service routing protocol.


gateways/proxies

gateways , proxies enable connection numerous technology types regardless of age communicate across ip-based network. gateways , proxies essential in operation of network because many different technologies used communicate in each domain. these systems facilitate transition of legacy on-board infrastructure, transmission systems, tactical data link systems, , user applications objective airborne network systems. therefore, temporary until platforms use standardized ip radio transmission.


performance enhancing proxies

performance enhancing proxies improve performance of user applications running across airborne network countering wireless network impairments, such limited bandwidth, long delays, high loss rates, , disruptions in network connections. proxy systems implemented between user application , network , can used improve performance @ application , transport functional layers of osi model. techniques can employed include:



compression: data compression or header compression can used minimize number of bits sent on network.
data bundling: smaller data packets can combined (bundled) single large packet transmission on network.
caching: local cache can used save , provide data objects requested multiple times, reducing transmissions on network (and improving response times).
store , forward: message queuing can used ensure message delivery users become disconnected network or unable connect network period of time. once platform connects, stored messages sent.
pipelining: rather opening several separate network connections pipelining can used share single network connection multiple data transfers.
protocol streamlining: number of transmissions set , take down connections , acknowledge receipt of data can minimized through combination of caching, spoofing, , batching.
translation: translation can performed replace particular protocols or data formats more efficient versions developed wireless environments.
embedded acknowledgments: acknowledgements can embedded in header of larger information carrying packets reduce number of packets traversing network.

the original shake shack located in madison square park in 2000, new york city began rebuilding of madison square park, had fallen state of disrepair , misuse. part of redevelopment, restaurateur danny meyer helped spearhead creation of madison square park conservancy redevelop it. 1 of first things conservancy did in goal improve park host art exhibit called <3 taxi inside of park raise awareness of renewal effort. meyer s director of operations, randy garutti, established hot dog cart run out of kitchen of eleven madison, 1 of meyer s union square hospitality group (ushg) operations. on time cart became extremely successful, , remained in operation 3 years. in 2004, city began taking bids operate new kiosk-style restaurant within park; meyer outlined idea space, , opened first shake shack in july 2004. beginning restaurant not designed chain; intended single shop location designed new york city. however, original location s sales continued grow, group realized there market expan...
