Industrial Ethernet is trending to be the principal infrastructure choice for mission-critical industrial automation and control applications. Industrial Ethernet is built on the same standards-based networking platform as enterprise Ethernet, which has long reigned as the universal network solution.
Architecting Low Latency Cloud Networks
[ Source: Arista Networks ]
June 2009-
As data centers transition to next generation virtualized & elastic cloud architectures, high performance and resilient cloud networking has become a requirement for delivering always-on, always-available applications.
Over the last decade response time requirements have been rigorously tightened, toward fractions of a second, and both network and compute latencies need to be reduced in parallel. An architectural approach is needed so that response times are consistently and measurably enhanced across a wide set of ....

Cloud computing is a compelling way to deliver web-based and non-web-based applications that better utilize the physical infrastructure, while lowering costs by moving from silos of expensive customized servers to racks of cost-effective ones. Due to the elastic nature of clouds, a particular application may be delivered from one physical location at a given moment but from a different, potentially far-away location in the same cloud at a later moment. Performance and scaling of cloud ....

Zero latency is the optimal trading speed that all firms hope to achieve at some point. But until that can become a reality, there is a race to keep reducing latency from all aspects of the trading process. From the server to the messaging to the sending and receiving of data, each piece must be optimized to reach the goal of zero latency. There are many avenues companies are looking at to reduce variables and ....
Cisco Service-Oriented Network Architecture: Support and Optimize SOA and Web 2.0 Applications
[ Source: Cisco ]
April 2008-
Both Web 2.0 and SOA create highly distributed composite applications that unite components or subsystems to form higher-level functional systems or target applications. Each may require several cross-network traversals, increasing the potential for inconsistent performance or security problems. This paper describes how a pervasive, reliable network assures that all elements of highly distributed composite applications operate quickly, efficiently, and securely. The network helps create an optimal foundation for Web 2.0 and SOA composite applications, enabling ....
Drivers and Applications for the Power Over Ethernet Solution

January 2008-
This paper from Cisco Systems explains drivers and applications for the power over ethernet solution as the network has become an integral part of the enterprise and small-to-medium business, a plethora of new applications has driven new devices onto the network infrastructure. PoE (Power over Ethernet) is the ability of the LAN switching infrastructure to provide power over the Ethernet copper wire to an endpoint. Cisco delivers both 10/100 and 10/100/1000 PoE ports, enabling use ....
MPLS AToM - Ethernet Over MPLS
[ Source: Cisco ]
January 2008-
This feature of MPLS AToM - Ethernet Over MPLS allows the user to connect two VLAN networks that are in different locations, without using expensive bridges, routers, or switches at the VLAN locations. The user can enable the MPLS backbone network to accept Layer 2 VLAN traffic by configuring the Label Edge Routers (LERs) at both ends of the MPLS backbone. Adding a point-to-point Virtual Circuit (VC) requires the user to configure the two VC ....
Buffers, Queues and Thresholds on Catalyst 6500 Ethernet Modules
[ Source: Cisco ]
January 2008-
With the wide variety of Ethernet modules currently available on the Catalyst 6500 series switches, determining the size of the port buffers, the number and type of the receive and transmit queues, and the number of tail-drop or Weighted Random Early Detect (WRED) thresholds can be a daunting task. Provides a brief discussion of how the port buffers, queues, and thresholds are used in the Catalyst 6500 series switch Ethernet modules, and it also describes ....
10-Gigabit Ethernet Switch Applications in ATCA

January 2008-
To help standardize building practices for future platforms, the telecom market is moving toward adopting the Advanced Telecom Computing Architecture (ATCA). The availability of silicon solutions for 10-Gigabit Ethernet creates a wealth of opportunities for system developers who can leverage these solutions in ATCA products. 10-Gigabit Ethernet provides the cost-effective bandwidth needed to open existing throughput bottlenecks as well as fuel a variety of emerging applications.
Monitoring Ethernet Connectivity

January 2008-
Although the Ethernet promises high probability packet delivery between all pairs of hosts, defects in the installation can sometimes prevent some pairs of hosts from communicating very well. This paper published by HP describes a method that was developed and used at Carnegie Mellon University during 1984-1985 to monitor the connectivity between all pairs of hosts on the Ethernet. The method is based on sending test packets from a central station through various cyclic routes ....
