Efficient Use of Memory Bandwidth to Improve Network Processor Throughput: This paper considers the efficiency of packet buffers used in packet switches built using Network Processors NPs. Packet buffers are typically implemented using DRAM, which provides plentiful buffering at a reasonable cost. The problem addressed in this paper is that a typical NP workload may be unable to utilize the...; Tags: Processor, Bandwidth, DRAM, Network, Memory Bandwidth, Packet Buffer, Memory, Routers & Switches, Semiconductors, Hardware, Components, Networking; White papers 2008-01-01

An Efficient Buffer Management in a Network Interface Card: This paper proposes a dynamic packet buffer management algorithm for a protocol processor in a network terminal. The protocol processor is to handle high-speed data streams, more than 10 Gb/s, in a Network Interface Card NIC. There are two types of packet buffer management algorithms, static and dynamic. In general,...; Tags: Network, Network Interface Card, Management Algorithm, Protocol Processor, Engineering, Networking; White papers 2006-07-01
Packet Buffer Management for a High-Speed Network Interface Card: Packet buffers in a smart network interface card are managed in a way to reduce any packet losses from high-speed burst incoming data. Currently, two types of packet buffer management techniques are used. They are static buffer management and dynamic buffer management techniques. Dynamic buffer management techniques are more efficient...; Tags: Technique, Packet Loss, Management Technique, Buffer Management Technique, Productivity, Networking; White papers 2007-05-30
Achieving 100% Throughput in TCP/AQM Under Aggressive Packet Marking With Small Buffer: This paper investigates the performance of TCP/AQM systems with ECN marks under the aggressive scale for packet marking and a buffer of size smaller than O(?N). Under such a scale, the paper demonstrates that randomness both in packet arrivals and in packet marking must be taken into account and developed...; Tags: Packet, Buffer, North Carolina State University, Performance Management, Human Resources, Workforce Management; White papers 2006-08-01
Design and Performance of FDL Buffers in Optical Switches: A key technique for reducing packet blocking in optical switches is by temporarily buffering packets in Fiber Delay Lines FDLs. The packet blocking probability depends on the FDLs design as well as on how packets are scheduled to the FDL buffers. This study compares between the blocking probabilities of the...; Tags: Performance, Fiber, Network Technology, Networking; White papers 2007-07-05

TCP WestwoodVT: A Novel Technique for Discriminating the Cause of Packet Loss in Wireless Networks: Conventional TCP in wireless environment cannot differentiate packet losses caused by network congestion from those caused by wireless link errors, thus, resulting in severe performance degradation. Accordingly, efficient operation of TCP in wireless networks is a critical issue in the context of differentiation between packet loss. Towards this issue, the...; Tags: Technique, Network, TCP, Wireless Network, Packet Loss, Tcp/Ip, Networking, Wi-Fi, Wireless; White papers 2007-08-28
Dynamic Input Buffer Allocation (DIBA) for Fault Tolerant Ethernet Packet Switching: This paper describes a new fault-tolerant architecture to realize an Ethernet layer-2 switch. This architecture includes a memory buffer scheduler to assign memory buffers dynamically to the input ports of the switch. To evaluate this architecture and produce throughput and latency projections, the paper has developed a switch simulator called...; Tags: Fault-tolerance, Northeastern University; White papers 2008-01-01
Buffer Overflows for Beginners: So what is a buffer overrun and why should you care? The SANS institute a few months back released a list of the 10 most commonly used methods to break into servers. Of these ten a large number can be attributed to buffer overrun vulnerabilities. They are a major problem....; Tags: Buffer-overrun, Next Generation Security Software Ltd., Buffer-overflow; White papers 2000-07-07
Modern Network Security: The Migration to Deep Packet Inspection: The evolution of network and application-layer security threats has significantly altered the requirements for modern network security architecture. Three years ago, a simple Stateful Packet Inspection SPI Firewall was sufficient to stop basic attacks such as port scans and DoS attacks. Now, application-layer buffer overflow attacks, Spam, Spyware, Polymorphic Trojans,...; Tags: eSoft, Network, Migration, Security, Networking, Network Security, Viruses And Worms; White papers 2005-07-14
Optimal Choice of the Buffer Size in the Internet Routers: The paper studies an optimal choice of the buffer size in the Internet routers. The objective is to determine the minimum value of the buffer size required in order to fully utilize the link capacity. There are some empirical rules for the choice of the buffer size. The most known...; Tags: Router, Internet Router, Computer Science, Size, Routers & Switches, Networking; White papers 2007-01-01
Combinatorics of TCP Reordering: This paper studies a combinatorial problem motivated by a receiver-oriented model of TCP traffic from, that incorporates information on both arrival times, and the dynamics of packet IDs.

An Experimental Study of Router Buffer Sizing for Mixed TCP and Real-Time Traffic: Recent research results on Internet router buffer sizing suggest that when TCP traffic is well-paced, Internet routers need as few as 20-30 packet buffers to realise near maximum link throughputs, independent of link capacities and number of TCP flows. However, these studies have ignored non-TCP traffic, on the grounds that...; Tags: Router, Traffic, TCP, Tcp/Ip, Routers & Switches, Networking; White papers 2006-07-12
