| PSync version 0.1.0 |
| ------------------- |
| |
| Release date: January 25, 2019 |
| |
| Version 0.1.0 is the initial release of PSyncPSync library implements the `PSync protocol <https://named-data.net/wp-content/uploads/2017/05/scalable_name-based_data_synchronization.pdf>`_. It uses Invertible |
| Bloom Lookup Table (IBLT), also known as Invertible Bloom Filter (IBF), to represent the state |
| of a producer in partial sync mode and the state of a node in full sync mode. An IBF is a compact data |
| structure where difference of two IBFs can be computed efficiently. |
| In partial sync, PSync uses a Bloom Filter to represent the subscription of list of the consumer. |
| PSync uses `ndn-cxx <https://github.com/named-data/ndn-cxx>`_ library as NDN development |
| library. |

| |
| PSync supports the following features: |
| |
| - **Partial Synchronization** |
| |
| + Allows consumers to subscribe to a subset of a producer's offered prefixes. |
| + Consumer can sync with any replicated producer in the same sync group. |
| + A PartialProducer class to publish prefixes and updates. |
| + A Consumer class to subscribe to the producer (hello) and listen for updates (sync). |
| |
| - **Full Synchronization** |
| |
| + Similar to ChronoSync, allows full synchronization of names amongst all the nodes in the sync group. |
| + FullProducer class can be used start syncing with a sync group. |
| |
| - **Miscellaneous** |
| |
| + Uses ndn-cxx **SegmentFetcher** to segment hello and sync data. |
| + Provide a SegmentPublisher that can be used by other NDN applications. |
| + Examples are provided in `examples` folder to show how to use the library. |
