RSS sonetMaking Ethernet Over SONET Fit a Transport Network Operations Model
White Paper With the emergence of the Internet and data traffic, the North American network, which is mostly based on SONET technology, will have to adapt and ubiquitously support Ethernet with the same OAM capabilities as today's legacy DS1 and DS3 services. [20 Jul 2004]
The Broad (and Surprising?) Future of SONET
White Paper The advancement of SONET technology, embodied in what are known today as MSPPs, continues to promise future substantial benefits for network providers by extending the life of familiar operations methods and procedures, thereby leveraging existing... [20 Jul 2004]
Quad-Port Gigabit Ethernet Over SONET/SDH
White Paper The Quad-Port Gigabit Ethernet (GbE) over SONET/SDH design is a system solution for transporting GbE frames over existing SONET/SDH rings or point-to-point connections. It is provided using a combination of SONET/SDH and GbE standard products... [10 Apr 2008]
Accurate High-Speed SONET/SDH Jitter Measurement
White Paper Learn the principal sources of SONET/SDH jitter, the reasons previous testers gave such widely differing measurements, and the new ITU-T 0.172 process for accurately calibrating jitter signals. [10 Apr 2008]
Grooming of Arbitrary Traffic in SONET/WDM BLSRs
White Paper SONET add-drop multiplexers (ADMs) are the dominant cost factor in the SONET/WDM rings. They can potentially be reduced by optical bypass via optical add-drop multiplexers (OADMs) and traffic grooming. [10 Apr 2008]
Hitless Network Engineering of SONET Rings
White Paper This paper explores the challenges in engineering SONET rings to support higher traffic volumes. The paper presents an efficient algorithm called MobiRing that accounts for the unique constraints imposed by the SONET standard. [07 Dec 2006]
Traffic Delay in Ethernet Over SONET/SDH
White Paper Ethernet over SONET/SDH (EoS), or the combination of Virtual Concatenation (VCAT), Link Capacity Adjustment Scheme (LCAS), and Generic Framing Procedures (GFP), enables legacy transport networks to evolve into data-friendly environments... [21 Oct 2004]
Fibre Channel over SONET/SDH
White Paper This white paper is an introduction to Cisco Systems optical and storage product offerings, with a focus on the new SL-Series Fiber Channel/FICON over SONET/SDH interface card for the Cisco ONS 15454, and the Cisco MDS 9000 Family. [10 Apr 2008]
Detecting Configuration Errors in Operational SONET/SDH Networks
White Paper Large operational SONET/SDH networks have a significant amount of incorrectly configured equipment that affects network reliability and performance. These configuration errors cause latent errors and are hard to detect because they are dormant... [07 Dec 2006]
Minimal Cost WDM SONET Rings That Guarantee No Blocking
White Paper Minimal cost networks are presented when SONET UPSR and BLSR networks are deployed over a WDM fiber ring. The primary cost is the number of SONET ADMs, and a secondary cost is the number of wavelengths. [21 Oct 2004]
PESO: Low Overhead Protection for Ethernet Over SONET Transport
White Paper This paper addresses the issue of reliable transport of emerging data services in Ethernet over SONET (EoS) networks that require protection guarantees beyond standard best effort delivery. It argues that the current consensus of using Ethernet... [21 Oct 2004]
A Novel Efficient Technique for Traffic Grooming in WDM SONET With Multiple Line Speeds
White Paper SONET rings remain the dominant optical transport architecture in the metropolitan area. To support traffic growth on these rings, WDM technology is used to provide multiple SONET rings on the same fiber, each SONET ring running on a separate... [21 Oct 2004]
A New Efficient Integrated Routing Scheme for SDH/SONET-WDM Multilayer Networks
White Paper This paper presents and evaluates the new Weighted Integrated Routing scheme to solve the problem of dynamic routing and traffic grooming in meshed SDH/SONET-WDM multilayer networks. In optical networks, transmission rates have dramatically... [21 Oct 2004]
Improving Performance of SDH/SONET-WDM Multilayer Networks Using Weighted Integrated Routing
White Paper This paper deals with routing schemes in SDH/SONET-WDM multilayer networks applying Synchronous Digital Hierarchy (SDH) or Synchronous Optical Network (SONET) on top of a dynamic photonic network in Wavelength Division Multiplex technology (WDM). [21 Oct 2004]
Efficient Transport of Storage and Ethernet Across Hybrid DWDM and SONET/SDH Networks
White Paper This paper describes an innovative solution to efficiently transport Gigabit Ethernet and Storage Area Network (SAN) protocols from Multiple Dense Wavelength-Division (DWDM) access rings across the core SONET/SDH network. [06 Oct 2006]
