Abstract: An emergency call data relay includes a frame buffer and a frame handler. The frame buffer stores data frames received from a central system (e.g., a central CPE host). The data frames include call data associated with an emergency call being handled at a remote system (e.g., a PSAP) connected to the central system. The frame handler receives a data frame from the frame buffer, identifies a remote system handling the emergency call associated with the call data based on a network address in the data frame, extracts the call data from the data frame, and generates an output packet for a data gateway. The output packet has a header indicating a particular data gateway profile associated with the identified remote system handling the emergency call.

Abstract: Techniques for amortizing metadata updates due to data delete operations in data storage systems that implement log structured storage of data from virtual volumes. The techniques employ a segment database (DB) and a deleted chunk DB. The segment DB is implemented as a key-value store.

Stored segments of log structured data can also be effectively “cleaned” in a background process that involves ordered traversals of the segment DB and the deleted chunk DB, allowing for more efficient recovery of storage space consumed by the deleted data chunks.
