Mobile Backhaul: Overview
The exploding number of wireless customers using data-intensive smart phones poses a significant challenge for wireless providers. Legacy TDM circuits that connect base stations to regional network controllers are now overloaded. Meeting the additional demand by provisioning more TDM circuits is cost-prohibitive, motivating providers to implement Carrier Ethernet solutions designed to transport wireless data-intensive traffic over mobile backhaul.
Moving to Ethernet transport from TDM transport requires significant technology additions to traditional Ethernet deployments. Ethernet wasn’t designed with ultra-high reliability, voice quality, and accurate timing in mind – a mainstay of TDM circuits. However, recent additions to the Ethernet standard allow it to match TDM features. For example, a TDM level of reliability can be attained using Ethernet operation, administration and maintenance (OAM ) protocols and failover techniques. Also, voice and video quality can be obtained by using quality of service (QoS) methods and parameters.
Ixia accelerates Ethernet-based mobile backhaul adoption and migration by providing a comprehensive testing solution. Ixia emulates link OAM and service OAM protocols. Ixia can also test both IEEE 1588v2 and ITU-T Sync-E Ethernet synchronization protocols. Additionally, Ixia can run Carrier Ethernet data plane capacity tests, verify QoS handling algorithms, and characterize maintenance and fault handling recovery of the carrier network.
Ixia evaluates your mobile backhaul and answers such critical questions as:
- Is my Carrier Ethernet network capable of supporting voice, video, and data traffic?
- Do my link and service OAM implementations allow full monitoring of my network?
- How can I test to MEF 9, 14, and 21 certification standards?
- How can I guarantee that my mobile backhaul migration follows the MEF 22 Mobile Backhaul Implementation Agreement?
- How will my network handle clock synchronization and clock recovery?
- Can my network handle IEEE 1588v2 and Synchronous Ethernet?
- If 1588v2 is used, how many slaves can the master support?
- How many subscribers can I support at high quality?
Ixia provides the most complete industry test solution by covering performance, conformance, and scalability testing for your mobile backhaul network.
