• SDH is PCM communication system that using synchronous clock to deliver traffic

• SDH (Synchronous Data Hierarchy) and Why SDH?• High transmission rates

• Disadvantages inherent in PDH

Network Synchronization

2/20/2016 26

Clocking Terminology

• Synchronization is required in order to meet network performance and availability requirements.

• Poor network synchronization will lead to large amounts of Jitter and Wander.

• This Jitter and Wander can lead to transmission errors and buffer under/overflow.

2/20/2016 32

Packet Based Clock Synchronization

• Ethernet is inherently an asynchronous networking system.

• Differences in timing at nodes within a network cause the receiving node to either drop or reread information sent to it.

• Achieve the required synchronization of the TDM nodes across the asynchronous Ethernet network, a clock recovery mechanism must be employed at the receiver side of a CESoETH connection.

2/20/2016 33

Packet Based Clock Synchronization (2)

• There are three categories of Clock solutions:• External source – GPS or TDM network. This is outside the scope of the Carrier Ethernet

domain.

• Synchronization of packet network – elaborated in the following sections.

• Synchronization over physical Ethernet – Synchronous Ethernet or SyncE

2/20/2016 34


• Technique for Sync:

1. Adaptive Clock Recovery (ACR)2. Network Time Protocol (NTP)3. IEEE-1588 v2 (PTP)4. Synchronous Ethernet (Sync-E)

2/20/2016 35


• Adaptive Clock Recovery (ACR)• Adaptive Clock Recovery (ACR) is

used in conjunction with circuit emulation services.

• adaptive methods adjust a local frequency reference to ensure that the rate of data being transmitted by the packet to TDM IWF matches the rate of data reception at the TDM to packet IWF.

2/20/2016 36


• Adaptive Clock Recovery (ACR)(2)

2/20/2016 37


• Network Time Protocol (NTP)• The main issue with NTP is that its accuracy can degrade substantially during periods of

network congestion

• defined in RFC 1305, including a recovery algorithm

• protocol uses four timestamps

• It was not designed for highly accurate frequency distribution, as is now being considered for telecommunication applications, nor for the highly accurate phase requirements of the TDD mobile technologies.

2/20/2016 38


• Network Time Protocol (NTP) (2)

2/20/2016 39


• The Precision Time Protocol (PTP)• IEEE1588v2 and its Precision Time Protocol (PTP) message exchange is another

mechanism that can be used to synchronize time and timing within a network

• Providing the highest level of accurate frequency, phase, and time of day to wireless backhaul networks.

• Similar with NTP but enhance some hardware-based time-stamping

2/20/2016 40


• The Precision Time Protocol (PTP)(2)• PTP Component

2/20/2016 41


• The Precision Time Protocol (PTP)(3)• Transparent Clock Type

End to End Peer to Peer

2/20/2016 42


• Synchronous Ethernet• The Synchronous Ethernet (SyncE) approach provides a mechanism to deliver a

network traceable physical layer clock over IEEE 802.3 PHYs with Ethernet Equipment Clock (EEC) as specified in ITU-T G.8262.

• The architectural aspects of Synchronous Ethernet are defined in ITU-T G.8261. SyncEprovides the capability to provide an Ethernet clock that is traceable to a primary reference clock (PRC) as defined in ITU-T G.811

• It should be noted that SyncE requires all network elements in the network to be upgraded to support SyncE. Therefore SyncE might only be practical for use in small network domains, while a hybrid solution complemented by a packet-based synchronization method would be required to extend its reach.

2/20/2016 43


• Synchronous Ethernet (2)• Synchronous Status Message (SSM)

• Determine the quality level of the clock sourcing a given synchronization trail

• Allow a network element to select the best of multiple input synchronization trails

• Avoid the creation of timing loops.

• SSM of Synchronous Ethernet uses an Ethernet OAM PDU that uses the slow protocol subtype (ITU-T G.8264)

• SSM of Synchronous Ethernet uses an Ethernet OAM PDU that uses the slow protocol subtype.

2/20/2016 44


• Synchronous Ethernet (3)• Synchronous Ethernet (Sync-E)

• Ethernet Port can derive the physical layer transmitter clock

• Not influenced by impairments introduced by the higher levels of the networking technology (packet loss, packet delay variation).
