Many networking applications require fast state lookups in a concurrent state machine,which tracks the state of a large number of flows simultaneously.We consider the question of how to compactly represent such concurrent state machines. To achieve compactness,we consider data structures for Approximate Concurrent State Machines (ACSMs)that can return false(More)
A counting Bloom filter (CBF) generalizes a Bloom filter data structure so as to allow membership queries on a set that can be changing dynamically via insertions and deletions. As with a Bloom filter, a CBF obtains space savings by allowing false positives. We provide a simple hashing-based alternative based on d-left hashing called a d-left CBF (dlCBF).(More)
— In recent work, the authors introduced a data structure with the same functionality as a counting Bloom filter (CBF) based on fingerprints and the d-left hashing technique. This paper describes dynamic bit reassignment, an approach that allows the size of the fingerprint to flexibly change with the load in each hash bucket, thereby reducing the(More)
—More fundamental than IP lookups and packet classification in routers is the extraction of fields such as IP Dest and TCP Ports that determine packet forwarding. While parsing of packet fields used to be easy, new shim layers (e.g., MPLS, 802.1Q, MAC-in-MAC) of possibly variable length have greatly increased the worst-case path in the parse tree. The(More)
Left ventricular pseudoaneurysms (LVPs) occur as a complication of myocardial infarction, cardiac surgery and, rarely, due to thoracic trauma, infective pericarditis or iatrogenisis due to accidental perforation of the myocardium. Ventricular pseudoaneurysms are acquired by blood-filled spaces outside the cardiac chambers communicating with the ventricle.(More)
Cloud Management Systems (CMS) such as Open Stack are commonly used to manage IT resources such as computing and storage in large data enters. Recently, CMS are starting to offer customers also the possibility to customize their network infrastructure, allowing each tenant to build his virtual network made of elementary blocks such as traffic monitors,(More)
The effect of copper interconnects on memories is investigated. HSPICE simulations indicate a 30% improvement in the access time of a 2K×16 bit SRAM with copper interconnects compared to aluminum. Circuit techniques that utilize the transmission-line effect of copper interconnects for low-power operation are presented. HSPICE simulation results indicate(More)
BACKGROUND Facial cosmetic results are one of the most concerning issues for the parents who get their children operated for cleft lip. Moreover, the postoperative care of the surgical site, the discomfort associated with the suture removal, and additional visit for suture removal are other reasons which encourages one to use any new technologies that may(More)
