Synchronous Ethernet Technology Brief (Europe) REF: SyncE /Tech Brief/__032012 TECHNOLOGY BRIEF Synchronous Ethernet Standard Enables Mobile Operators to Cope with Explosive Growth of Smartphone Applications Synchronous Ethernet (SyncE), a standard for distribution of frequency over Ethernet links, is the ability to provide PHY-level frequency distribution through an Ethernet port. This is particularly important for mobile networks that need accurate and stable frequency reference. Previously, Synchronous Digital Hierarchy (SDH) and Synchronous Optical Networking (SONET) equipment were used in conjunction with external timing technology (Primary Reference Clock (PRC) or Primary Reference Source (PRS)) to provide accurate and stable frequency reference. Using similar external references as a source, SyncE, aims to achieve the same function without needing to rely on Cesium oscillators and/or Global Positioning System (GPS) as the clock source like in earlier systems. Following the birth of mobile internet, there has been tremendous growth in smart device usage, including smart phones and tablets. Consequently, the demand for mobile data has grown exponentially, placing great demand on mobile networks that were originally designed to cope with voice data only. Most industry observers believe this demand for mobile data will continue to spike upwards in an exponential fashion over the next decade, especially as 4G- and LTE-ready devices become commonplace. And with more and more data services coming on stream, mobile network operators are going to need networks that can handle larger and larger amounts of traffic. In most mobile networks, Ethernet is still the only connection from hub to remote nodes, so it must provide a means to distribute frequency to these remote sites for the base stations to be synchronized. This synchronization allows efficient use of the radio spectrum, thus improving usage and utilization, enhancing customer experience, and reducing costs. In carrier and Metro Ethernet networks, IP voice and Metro Ethernet appear likely to be the two strongest areas for potential growth in the near future. This means more traffic will be transferred to Metro Ethernet networks, with voice continuing to remain a key factor affecting revenue. Of course, Service Providers want to continue servicing existing customers on these "legacy" networks, even as they enhance their access and core networks to handle the huge surge in traffic and the change in traffic patterns. This situation translates to increased importance of applications such as mobile backhaul. Physical layer SyncE provides the best technical option for guaranteed frequency accuracy and stability. For backhaul requirements where an Ethernet network interfaces with traditional Time-Division Multiplexing (TDM) networks, SyncE can provide the clocking input required for TDM links at the endpoints as well as for next-generation Ethernet-based base stations. Although it is also possible to place reliable PRS capability at each node, hub, and remote site, a primary benefit of SyncE is the ability to eliminate this need and thus reduce network capital expenditures (CAPEX) and ongoing maintenance and operating costs (OPEX). In addition, it allows Service Providers to keep existing revenue streams alive and create new ones while simplifying the network design and reducing Total Cost of Ownership (TCO). The Edge-Core Networks Layer 2 Gigabit Ethernet carrier-grade ECS4810-12M, with Synchronous Ethernet (SyncE) support, flexible combination Gigabit ports, comprehensive Quality of Services (QoS), advanced operation, administration, and maintenance (OAM), and continuous availability architecture is ideal for the demanding, high-performance requirements of both today and tomorrow’s mobile and Metro Ethernet networks.

  • Synchronous Ethernet Solutions with Altera Fpgas and Silicon Labs Jitter-Attenuating Plls
    Synchronous Ethernet Solutions with Altera FPGAs and Silicon Labs Jitter-Attenuating PLLs Hoss Rahbar, Product Marketing Manager, Altera Han Hua Leong, Design Engineer, IP and Device Software Engineering, Altera Bill Simcoe, Marketing Manager, Silicon Labs WP-01257-1.0 White Paper Introduction Synchronous clock signals are required for proper operation of voice communications, cellular wireless networks, passive optical networks (PONs), and a variety of other time-critical networking applications. Traditional time division multiplexed (TDM) telecom equipment—to support standards like Synchonous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH)—operate with synchronized clock signals. Nodes in these networks are synchronized to a primary reference clock (PRC) or primary reference source (PRS) with long-term frequency accuracy better than 1 part in 1011. The PRS/PRC clocks in TDM networks are provided by highly accurate and stable atomic clocks, or signals from the global positioning system (GPS). The clocks are then distributed to all the nodes in the network over the same connections that transport clients’ voice and data. The network nodes then synchronize their locally generated clocks to the PRS/PRC clock. Ethernet has become the network interface of choice in enterprise, metro, and some core networks. Ethernet networks can be used to transport voice, data, and video at high data rates for substantially lower equipment and service costs than traditional networks. Large capital savings can be realized by using Ethernet for synchronizing network nodes instead of using a more expensive specialized synchronous network. The IEEE 802.3 Ethernet standard is not specified to accurately transfer a clock from the transmitter to the receiver.

    WHITEPAPER Joan d’Austria, 112 - Barcelona - SP - 08018 Chalfont St Peter - Bucks - UK - SL9 9TR www.albedotelecom.com Synchronous Ethernet explained 1. FROM ASYNCHRONOUS TO SYNCHRONOUS ETHERNET Synchronous Ethernet is an ITU-T standard that provides mechanisms to trans- fer frequency over the Ethernet physical layer, which can then be made trace- able to an external source such as a network clock. On this case Ethernet links are part of the synchronization network (see Figure 2). The proposal to specify the transport of a reference clock over Ethernet links was brought by operators to ITU-T Study Group 15 in September 2004. The aim of Synchronous Ethernet is to avoid changes to the existing IEEE Ethernet, but to extend to work as a proper synchronous network. On many respects the evolution to a synchronous Ethernet network is equiva- lent to the one that occurred from PDH/T-Carrier to SDH/SONET and the causes are similar. The higher bit rates are the most important is to keep transmission synchronized by a unified clock in order to keep clock fluctuations and offsets under control as they are a main cause of errors a poor QoS. Despite being an IEEE standard, Ethernet architecture has been described in ITU-T G.8010 as a network made up of an ETH layer and a ETY layer. Written in simple terms, the ETY layer corresponds the physical layer as defined in IEEE 802.3, while the ETH layer represents the pure packet layer.

  • A RAD White Paper Abstract Worlds Apart – SONET/SDH and Ethernet
    Synchronous Ethernet – A RAD White Paper Yaakov (J) Stein, Chief Scientist, RAD Data Communications, Ltd. Alon Geva, Timing specialist, RAD Data Communications, Ltd. Abstract As more and more traffic is being delivered in Ethernet format, carriers are realizing the advantages to converging on a pure Ethernet infrastructure, but are not able to do so with Ethernet as presently defined. New ITU-T Recommendations, such as Y.1731 for Ethernet OAM and G.8031 for Ethernet protection switching, provide features essential for operational maintenance of Ethernet networks. Recently proposed mechanisms for configuring point-to-point connections in Ethernet networks close another gap between Ethernet and SONET/SDH networks. The final difference between conventional TDM-based networks and Ethernet is that the former also transport frequency information, needed for some applications, while Ethernet does not. Numerous methods have been suggested for augmenting Ethernet to distribute frequency and/or timing information, such as IEEE 1588, IETF’s NTP, and methods developed for use of TDM pseudowires. In this article I will talk another method for transport of synchronization over Ethernet networks, for those applications that need it. This method locks the timing of the Ethernet physical layer, much the same way that SONET/SDH does. This enables simple recovery of the physical layer timing, which can be used directly by locking downstream networks and applications, or indirectly by using the physical layer timing as a common reference. Worlds apart – SONET/SDH and Ethernet Ethernet is by far the most widely deployed network technology, being used for transport over local and metro area networks, and the demand has been steadily increasing for it to become the standard handoff interface for network interconnection.
