Abstract: A method and system of improving TCP performance by offloading TCP processing to a protocol acceleration module is provided. For example, one or more in-sequence data packets being transmitted between a protocol sender and a protocol receiver is observed, and either the protocol sender or receiver resides within a virtualized host. A determination is made whether the protocol packet buffer within the protocol acceleration module is full. In further examples, one or more in-sequence packets are processed in an accelerated mode, where the processing includes copying the in-sequence data packets into the protocol packet buffer.

Abstract: Example embodiments described herein provide systems and methods for transmitting data packets between a protocol sender and a protocol receiver in a cloud environment, having either the protocol sender or the protocol receiver residing within a virtualized host. A protocol acceleration module may observe the data packets transmitted along the data path between the protocol sender and the protocol receiver using protocol stack configuration information of the protocol sender. The protocol acceleration module may override the protocol stack configuration information with policy-based protocol stack configuration information such that data packets transmitted from the protocol acceleration module to the protocol receiver use the policy-based protocol stack configuration information. For various embodiments, the protocol stack configuration information of the protocol sender is not modified.

Abstract: A combined hash table/bucket trie technique facilitates fast, deterministic, memory-efficient exact match look-ups on extremely large tables. A limited number of hash keys which collide on the same location can be stored in the hash table. If further keys collide on the same location, a bucket trie is formed, the colliding keys are stored in the trie, and trie traversal information is stored in the hash table. Regardless of the number of buckets in the trie, an input key need only be compared with the keys in one bucket to detect a stored key identical to the input key or conclude that no stored key is identical to the input key.
