☆ Efficient Batched Synchronization

✎

Acting

as a middleware between the user's file storage system and a

cloud storage application (e.g. Dropbox), our proposed UDS (i.e.

update-batched delayed sync) mechanism properly batches updates

from clients to minimize the "traffic overuse problem",

while preserving the rapid file synchronization that users

expect from cloud storage services.

✎efficiently schedules cloud bandwidth into end host peers to

maximize the bandwidth multiplier effect with a fine-grained

model and fast-convergent iterative algorithm ("FIFA").

content distribution)

✎dynamically tracks and integrates various third-party servers,

contents and data transfer protocols all over the Internet into

a large, open and federated P2SP (peer-to-server/peer) platform,

so as to accelerate the content distribution from servers to

clients and among peer swarms. It also facilitates

load-balancing among the involved servers.Please try the large-scale

桃花庵歌(明)唐寅

桃花坞里桃花庵，桃花庵下桃花仙。  桃花仙人种桃树，又摘桃花卖酒钱。

酒醒只在花前坐，酒醉还来花下眠。  半醒半醉日复日，花落花开年复年。

但愿老死花酒间，不愿鞠躬车马前。  车尘马足富者趣，酒盏花枝贫者缘。

若将富贵比贫贱，一在平地一在天。  若将贫贱比车马，他得驱驰我得闲。

世人笑我太疯癫，我笑他人看不穿。  不见五陵豪杰墓，无花无酒锄作田。
