Title:
Huawei PTN Leased Line Solution Performance Evaluation
Publication date:

Abstract:
With telecom carrier networks’ evolution to all-IP, service network and network
edge client side’s migration to be IP-based is accelerating. This trend makes the
Synchronous Digital Hierarchy (SDH) circuit switching technology, which has
been used for more than 20 years, to be stretched to its limit. Therefore, the all-IP
trend and bandwidth growth requirements are driving end-to-end transport
network migration from circuit switching SDH to packet switching Packet-Based
Transport Networks (PTN).
Huawei SPTN series’ Ethernet Private Line (EPL) leased line service provides a
variety of port speeds, adjustable bandwidth granularity, ultra-low delay
forwarding, and similar performance as SDH/MSTP devices’. Meanwhile, with
GUI-based end-to-end service deployment and maintenance, Huawei PTN
products are easy to manage.
Tolly engineers verified that the delay of the EPL service with PTN devices was
less than 110μs after 3 hops and less than 220μs after 6 hops for all tested frame
sizes. The jitter was less than 1μs after 3 hops and less than 1.5μs after 6 hops for
all tested frame sizes. Overall, PTN devices’ performance was on the same level as
SDH/MSTP devices’.
