Wire-speed traffic management in Ethernet switches

چکیده
Price advantage & ease of provisioning of Ethemet over ATM is spurring the deployment of traditional Ethemet switches in Access Networks. Fast Ethemet (FE) and Gigabit Ethemet (GE) switches for enterprise LANs lack traffic management (TM) features making them unsuitable for widespread QoS enabled Access Networks deployment. In this paper, we present efficient hardware architectures for Ethemet switches to implement wire speed packet classification, bandwidth policing and rate shaping. The Packet Classification Engine can support configurable multi-dimensional classification at 15Mpacketds. These hardware StNCtureS have been incorporated into Infineon Technologies’ configurable 8G Ethemet ‘Switch-on-a-chip’ (PLB2800) and fabricated using 0.1 8pm technology.

Queue Management for Shared Bu er Switch Architecture
| In this paper, we present the design of a scalable queue management for shared bu er switch architecture by using non-linked-list implementation. In the traditional switch design, linked-list is the widely adopted implementation to maintain the packet bu er. However, to design a linked-list architecture in hardware increases the size of chip and also limits the operating frequency. By using t...
متن کاملEnhanced ethernet congestion management scheme for multicast traffic
The Quantized Congestion Notification (QCN) is a Layer 2 congestion control scheme for Carrier Ethernet data center networks. The QCN has been standardized as an IEEE 802.1Qau Ethernet Congestion Notification standard. This paper report a results of a QCN study with multicast traffic and proposes an enhancement to the QCN. In fact, in order to be able to scale up, the feedback implosion problem...

A 1,000-fps visual tracking system over a realtime network based on the standard Ethernet and UDP/IP technologies is presented. The system consists of a high-speed vision system, a host PC that executes motor-control tasks on an RTOS, and an easyto-construct configuration for real-time communication to deliver the high-speed visual feature information obtained by the vision system to the host P...
متن کاملIwarp Ethernet: Eliminating Overhead in Data Center Designs Latest Extensions to Ethernet Virtually Eliminate the Overhead Associated with Transport Processing, Intermediate Buffer Copies, and Application Context Switches to Make Multi- Gigabit Ethernet a Better Option for Data Center Designs
Organizations across the planet are experiencing rapid growth in both the volume of data they must process, and the speed at which processing must occur. As a result, the demand for networking throughput is growing faster than CPU clock speeds and memory bandwidth of servers that process data traffic. To keep up IT managers are building new data center infrastructures using a mix of the best av...
