High Performance Fibre Channel Solution With SONET/SDH
White Paper This paper discusses the factors that need to be considered when extending FC SANs over existing MAN/WAN infrastructures, and summarizes the three options in extension technologies: IP/Ethernet networks, Wavelength Division Multiplexing (WDM... [10 Apr 2008]
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]
OC-192c/STM-64c and 10 Gigabit Ethernet WAN PHY
White Paper Both of these interfaces support transmission at 9.6 Gbps, support SONET/SDH framing, and can be connected to SONET/SDH ADM or DWDM gear. The introduction of 10 Gigabit Ethernet (10 GbE) WAN PHY into the IP/Ethernet networking community has led to... [07 Feb 2008]
Operation, Management and Performance Issues of LAN Technologies Applied to WAN Architecture
White Paper Emerging technologies, like RPR, POS and GE, are being pushed to replace the traditional SONET/SDH and ATM in WAN. This paper evaluates performance issues of RPR, POS and GE on a testbed, including fault recovery, network stress, QoS and multicast... [05 Dec 2007]
Optimizing for Network Intra-POP Interconnections With Very Short Reach Interfaces
White Paper Cisco Systems has developed VSR-1 technology, the first functional 10-Gbps SONET/SDH interface that provides a low-cost, standard solution optimized for Very Short Reach (VSR) optical interconnections. [22 Feb 2007]
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]
SAN Over SDH/SONET for Business Continuity and Disaster Recovery
White Paper This white paper describes the business case for using SDH/SONET as the WAN between SAN islands. These solutions provide data connectivity between separate SAN islands within the enterprise using the Wide Area Network (WAN). [18 Aug 2006]
Ethernet Over SONET
White Paper The communications landscape is dominated by two differing technologies: Ethernet in the LAN for internal business communications; and SONET/SDH in the Telco/PTT WAN. To interface the LAN to the WAN provided by the Telco/PTT, historically, has... [01 Nov 2004]
The Status of the 10-Gigabit Ethernet Standard
White Paper Ten-gigabit Ethernet is designed for use in two major applications: firstly, local area networks (LAN) and, secondly, connection to SONET/SDH-based wide area networks (WAN). The four port types being specified for LAN applications and the three for... [01 Nov 2004]
Optical Storage Connectivity: Storage Over SONET/SDH
White Paper Nortel Networks has created solutions, which focus the power and proven capabilities of SONET and SDH on the current and pressing business problem of extending mainframe and open system traffic across WAN distances. [01 Nov 2004]
Cost-Effective Networking of Mission-Critical Storage Over Distance
White Paper Nortel Networks storage over SONET/SDH solution enables the transport of storage traffic over WAN distances (up to thousands of km) by using an innovative flow control scheme to ensure that there is no impact on the performance of active FC or... [25 Oct 2004]
Regional Networks for Broadband Cable Television
White Paper One of the outcomes of these trends has been a shift toward using standards-based digital transport (SONET and SDH) for the backbone interconnections within these regional networks. Simultaneously, the broadband communications operations that once... [24 Feb 2004]
Internet Protocol (IP) Internetworking Transport
White Paper Two of the most frequently considered options for providing IP transport include IP over point-to-point protocol (PPP) over synchronous optical network/synchronous digital hierarchy (SONET/SDH) (sometimes referred to as packet over SONET/SDH [PoS... [24 Feb 2004]
Global Optical Communication: RPR for Metro Networks
White Paper SONET)/synchronous digital hierarchy (SDH) circuit-switched layer. Metropolitan area network (MAN) plays a vital role in connecting users to wide area networking (WAN) services. Traditionally, MANs have been circuit-switched networks that are... [24 Feb 2004]
MPLS: The icing on the networking cake?
Comment An MPLS network will run over whichever mix of networking technologies it faces, including Ethernet, ATM and Synchronous Digital Hierarchy (SDH). In the metropolitan and wide area networks (MAN and WAN) MPLS has a bright future. [28 Nov 2001]
