Packet Network Synchronization
Industry Leading Timing Solutions for Packet Microwave Networks
Microwave mobile backhaul networks are rapidly evolving to packet networking driven by the evolution to LTE/4G. This evolution to packet is also having an impact on how network time distribution, or synchronization, is being implemented as the backhaul network transitions from a synchronized TDM network to an asynchronous Ethernet one.
Aviat Networks provides a variety of proven solutions for network synchronization over Ethernet. Layer 1-based Synchronous Ethernet (SyncE) was added to Aviat’s Eclipse platform in 2010, and was also showcased at the 2010 CEWC- EANTC interoperability demo. Eclipse also supports Layer 2-based IEEE 1588v2 packet synchronization transport, which was rigorously tested as part of Symmetricom’s SyncWorld™ Ecosystem Program, launched in early 2011. Aviat Networks and Symmetricom jointly completed extensive performance and interoperability tests to verify the performance of 1588v2 timing over various complex microwave backhaul network configurations under real-world deployment scenarios, including a 10-hop microwave backhaul network supporting Adaptive Coding and Modulation (ACM).
Webinar: Synchronization in the Mobile Networks
Aviat Networks speaker:
MEF representative and Senior Network Architect at Aviat Networks
This topical webinar replay talks about legacy sync, a summary of packet sync standards (SyncE, IEEE 1588 v2) and proprietary approaches. This is followed by a detailed look at clock sync in next-generation mobile networks.
Deploying IEEE 1588v2 Synchronization over Packet Microwave Networks
Joint Application Note with Symmetricom and Aviat Networks.
Mobile Backhaul Networks are evolving to packet, driven by 4G evolution, requiring high data and video traffic and growing number of apps, users, smartphones and tablet devices. 1588v2 and microwave are a perfect match for Mobile Backhaul evolution.
Synchronization over Microwave Mobile Backhaul Networks
Synchronization is creating quite a stir in the mobile backhaul industry as operators are wrestling with a variety of synchronization technology options including Synchronous Ethernet (SyncE) and Precision Time Protocol (PTP) a.k.a IEEE 1588v2. This paper reviews unique microwave backhaul characteristics that need to be taken into account in support of synchronization, and how each particular synch approach can be addressed.

Aviat Networks and Symmetricom Advance 1588v2 Network Synchronization over Microwave Backhaul
Aviat announced that it is one of the first members to join Symmetricom’s SyncWorld™ Ecosystem Program for delivering tested solutions for mobile backhaul network synchronization over packet microwave networks. Collaborating with Symmetricom strengthens Aviat Networks’ solution portfolio for IP network migration by adding IEEE 1588v2 synchronization capability, which enables the smooth introduction of 4G/LTE. This solution capability is in addition to Synchronous Ethernet (SyncE), which was added to Aviat’s Eclipse platform in late 2010.
Aviat Networks and Symmetricom jointly completed extensive performance and interoperability tests to verify the performance of 1588v2 timing over various complex microwave backhaul network configurations under real-world deployment scenarios, including a 10-hop microwave backhaul network supporting Adaptive Coding and Modulation (ACM). The successful result provides assurance to mobile operators currently deploying or planning to deploy IEEE 1588v2 timing over packet microwave.
