Abstract: A method may include (1) identifying a set of prefixes that (A) facilitate forwarding traffic within a network and (B) are organized as a tree data structure in connection with a table stored on a network device, (2) identifying, in the set of prefixes organized as the tree data structure, a parent prefix and a child prefix that corresponds to the parent prefix, (3) determining that the parent prefix and the child prefix share a certain number of most-significant bits in common with one another, (4) determining that the parent prefix and the child prefix share a forwarding behavior in common with one another and then, in response to determining that the parent prefix and the child prefix share the certain number of most-significant bits and the forwarding behavior in common with one another, (5) compressing the table stored on the network device by merging the child prefix with the parent prefix within the table. Various other apparatuses, systems, and methods are also disclosed.

Abstract: In general, the disclosure describes techniques for distributing processing of routes among multiple execution threads of a network device. In some examples, a method includes identifying, with a thread of a plurality of execution threads, a first route processing thread of the execution threads to process a first route of a routing protocol, the first route received by the network device; identifying, with the thread, a second route processing thread of the execution threads to process a second route of a routing protocol, the second route received by the network device; processing, by the first route processing thread executing on a first core of the plurality of processing cores, the first route; and processing, by the second route processing thread executing on a second core at least partially concurrently with the first route processing thread executing on the first core of the plurality of processing cores, the second route.
