Detailed Description

Bundle Cache element, containing information to uniquely identify a bundle on vfs.

Contains the filepath (the node/allocator and service), its expiry time and the (storage internal) duplicate index. With this information a bundle in storage is uniquely identified. The list should be maintained sorted by the expiry DTN time, so that egress can be sped up. A node of 0 is reserved for unused cache elements.

Field Documentation

◆ expiry

uint64_t cache_list_node_t::expiry

expiry time of the bundle

Definition at line 50 of file cache.h.

◆ index

uint8_t cache_list_node_t::index

Index in the storage.

In case the above do not uniquely identify a bundle. It is only an uint8 because we assume that there won't be more than 256 bundles with the same expiry time to the same node at any given time.

◆ node
