- New Wi-Fi chipsets promise up to 2x throughput of current 802.11n devices
- A couple of weeks ago I did a post on the Home Theater blog about Celeno Communications' wireless chip that the company claims can support four different HD streams simultaneously. Now another company has announced its own Wi-Fi technology that promises significant performance improvement over the 802.11n spec. Quantenna's QHS...

- Gnort: High Performance Network Intrusion Detection Using Graphics Processors
- The constant increase in link speeds and number of threats poses challenges to Network Intrusion Detection Systems NIDS, which must cope with higher traffic throughput and perform even more complex per-packet processing. This paper presents an intrusion detection system based on the Snort open-source NIDS that exploits the underutilized computational...

- The Hidden Cost of Overhead in MIMO Wireless LANs
- Multiple Input Multiple Output MIMO communication, enabled by the presence of multiple transmit and receive antennas in the communication link, is a physical layer technology that can improve throughput in WLANs. The cost of MIMO in terms of additional overhead, unfortunately, is often overlooked. Using representative physical and MAC models,...

- CDMA Channel Parameters Maximizing TCP Throughput
- A single TCP session traversing a wireless channel is considered in this paper, with a constant SIgnal to Noise Ratio SINR at the receiver. The problem of determining the optimal transmission energy per bit is considered, to maximize TCP throughput. Specifically, in the case where direct sequence spread spectrum modulation...

- Optimum Number of RLC Retransmissions for Best TCP Performance in UTRAN
- As far as transfer reliability is concerned, the wireless segment of UTRAN is the weakest part of an Internet session. To overcome this imperfection, the RLC protocol features a link-level retransmission mechanism. This paper shows by analytical means and computer simulations that for a given Block Error Rate BLER, the...

- Throughput and Transmission Capacity of Ad Hoc Networks With Channel State Information
- This paper develops a general framework for deriving the spatial throughput and transmission capacity of spatially Poisson distributed ad hoc networks for random (e.g., fading) channels, and random transmission distances. In both of these scenarios the randomness of the channels and ranges invariably lowers both throughput and transmission capacity assuming...

- Optimizing WAN Performance for the Global Enterprise
- To enhance Wide Area Network WAN throughput, Intel IT conducted a Proof of Concept PoC study to investigate new WAN optimization technologies and products. This paper achieved significant benefits to WAN throughput in their test network and in a pilot production network using devices that incorporated a variety of optimization...

- TCP NewReno: Slow-But-Steady or Impatient?
- This paper compares the throughputs of two different TCP NewReno variants, namely Slow-but-Steady and Impatient. The paper develops analytic throughput models of these variants as a function of round-trip time, loss event rate, and the burstiness of packet drops within a loss event. The models build upon prior work on...

- 802.11 Wireless Networks - A Peek Ahead at 802.11n: MIMO OFDM
- 802.11 Task Group N TGn has an interesting goal. Most IEEE task groups focus on increasing the peak throughput, making data fly as fast as possible during the time it is being transmitted. TGn's goal is to achieve 100 Mbps net throughput, after subtracting all the overhead for protocol management...

- Is SATA capped at 1.5Gbps on the 13" MacBook Pro
- For some, the pride of owning a brand new 13" MacBook Pro was shortlived as they discovered that the speed of their SATA hard drives are capped at 1.5Gbps, well below the expected 3.0Gbps. The difference between 1.5Gbps and 3.0Gbps makes little difference when you're dealing with...
