Abstract: Systems and techniques for distributed broadband network gateway for maximizing IPv4 address utilization. A dynamic host configuration protocol (DHCP) offer message is received by a distributed broadband network gateways (BNG) connected to a network. The DHCP offer message may have been forwarded from a DHCP server. The DHCP offer message is modified to replace an option 1 subnet mask with a 32-bit subnet mask and replace an option 3 router address with an internet protocol address of the distributed BNG to create a modified offer message. The modified offer message is transmitted to a user computing device. A route with a 32-bit subnet mask for the user computing device is advertised to other routers internal to the network of the broadband service provider.

Abstract: A method and apparatus are provided for split-terminating a secure client-server communication connection when the client and server perform mutual authentication by exchanging certificates, such as within a Lotus Notes environment. When the client submits a certificate to the server, an intermediary device intercepts the certificate and submits to the server a substitute client certificate generated by that intermediary. A certificate authority's private key is previously installed on the intermediary to enable it to generate public keys, private keys and digital certificates. With the private key corresponding to the substitute certificate, the intermediary extracts a temporary key from a subsequent server message. The intermediary uses the temporary key to read a session key issued later by the server. Thereafter, the intermediary shares the session key with another intermediary, and together they use the session keys to access and optimize (e.g., accelerate) messages sent by the client and the server.

Abstract: A simulator simulates routing system protocols to build routing tables corresponding to a modeled network, and a comparator compares the routing tables in the actual network to these simulator-created routing tables. Because the modeled system represents a fault-free version of the actual system, and assuming that the modeled routing system protocols are representative of the algorithms used in the actual routers, these simulator-produced routing tables can represent steady-state routing tables that should be present in the routers of the actual network at steady state. By querying each router in the actual network for its routing table and comparing each routing table to the corresponding simulator-produced routing table, any differences from the steady state can be identified.

Abstract: Transparent network devices intercept messages from non-transparent network devices that establish a connection. Transparent network devices modify these messages to establish an inner connection with each other. The transparent network devices mimic at least some of the outer connection messages to establish their inner connection. The mimicked messages and any optional reset messages are intercepted by the transparent network devices to prevent them from reaching the outer connections. Transparent network devices modify network traffic, using error detection data, fragmentation data, or timestamps, so that inner connection network traffic inadvertently received by outer connection devices is rejected or ignored by the outer connection network devices. Transparent network devices may use different sequence windows for inner and outer connection network traffic. To prevent overlapping sequence windows, transparent network devices monitor the locations of the inner and outer connection sequence windows and may rapidly advance the inner connection sequence window as needed.

Abstract: A method for identifying peptides using tandem mass spectrometry takes the spectrum for a peptide to be analyzed and uses a scoring function to score a match between the spectrum and each candidate peptide in a peptide database. The scoring function has a value corresponding to a number of fragment peaks in the spectrum that match fragment peaks in a spectrum of the candidate peptide. Using the match scores, a generating function of the spectrum is computed to determine the number of peptide reconstructions at each value of the scoring function. The generating function is then used to determine the number of candidate peptides for each match score and the probability of a peptide having a given match score to the spectrum. A spectral probability can be determined by calculating the total probability of all peptides with scores equal to or larger than the given match score.

Abstract: Relatively small capacity solid-state storage devices (SSD) are combined with larger capacity magnetic disk storage devices for storing storage block write data to ensure data consistency. Write operations are stored in a sequential write buffer in an SSD to guarantee the storage of write data and then copied from the sequential write buffer to the destination address in a magnetic disk storage device. The sequential write buffer store write data in locations corresponding to the order of receipt of write operations. Write data from the sequential write buffer is transferred to the magnetic disk storage device in the same order and a checkpoint index is frequently updated to indicate the completion of some transfers. During system initialization, the most recent value of the checkpoint index is retrieved and used as a starting location for transferring write data from the sequential write buffer to the magnetic disk storage device.

Abstract: Solid-state storage devices (SSD) are combined with larger capacity magnetic disk-based RAID arrays for storing write data to ensure data consistency across multiple RAID disks. Write operations are stored in a sequential write buffer in at least one SSD to guarantee their storage and then copied from the sequential write buffer to the destination address in RAID array. The sequential write buffer stores write data in locations corresponding to the order of receipt of write operations. Write data from the sequential write buffer is transferred to the RAID array in the same order and a checkpoint index is frequently updated to indicate the completion of some transfers. During system initialization, a copy of the sequential write buffer and its associated checkpoint index are retrieved and used as a starting location for transferring write data from the sequential write buffer to the magnetic disk storage devices in the RAID array.

Abstract: A network stack includes a packet loss analyzer that distinguishes between packet losses due to congestion and due to lossyness of network connections. The loss analyzer observes the packet loss patterns for comparison with a packet loss model. The packet loss model may be based on a Forward Error Correction (FEC) system. The loss analyzer determines if lost packets could have been recovered by a receiving network device, if FEC had been used. If the lost packets could have been corrected by FEC, the loss analyzer assumes that no network congestion exists and that the packet loss comes from the lossy aspects of the network, such as radio interference for wireless networks. If the loss analyzer determines that some of the lost packet could not have been recovered by the receiving network device, the loss analyzer assumes that network congestion causes these packet losses and reduces the data rate.
