Huawei announced the launch of its standard-based H-MPLS
(Hybrid-Multiprotocol Label Switching) prototype.
Huawei’s prototype is a lightweight unified bearer solution that can
simplify VLAN (Virtual Local Area Network) planning within an access network
and extend service scalability to the network at large.
Hybrid MPLS is based on Huawei’s SingleFAN broadband access solution and
it provides a unified bearer platform for ATM (Asynchronous Transfer Mode), TDM
(Time Division Multiplexing), Ethernet and IP (Internet Protocol) with MPLS
encapsulation. The technologies within Huawei’s H-MPLS solution have been
accepted under the ITU-T standard for GPON/XG-PON (Gigabit-capable Passive
Optical Network/10G Passive Optical Network).
As networks and services increasingly converge, MPLS is favored by many
operators worldwide as a unified bearer technology. Enterprise VPN, mobile backhaul,
and wholesale services require MPLS to extend from the metro to the network
edge.
However, native MPLS is designed for router platforms, which are
comprised of powerful hardware. Supporting native MPLS on edge devices
therefore increases both operational and capital expenses, impeding the ability
of operators to deploy MPLS to the network edge and limiting operators’ network
capability and service scalability.
Huawei used its access network
expertise to develop an innovative H-MPLS solution. Unlike traditional MPLS,
H-MPLS does not require direct configuration of network edge devices. As a
result, the number of nodes that needs to be managed can be reduced by up to 99
percent.
Using H-MPLS, there is no need to configure IP addresses and routing
protocols on edge devices, and this reduces configuration workloads by up to 90
percent. H-MPLS is also a cost-effective solution since it neither increases
the hardware cost of edge devices within the current access network nor the
cost of deploying MPLS widely.
“H-MPLS uses the existing OMCI(ONU Management and Control Interface)
management protocol to distribute MPLS labels over multiple PON systems,” said
Frank J. Effenberger, Huawei’s leader of optical access research.
H-MPLS further enhances the capability of Huawei’s SingleFAN broadband
access solution. A leading IP and optical access solution, SingleFAN has
enriched the lives of more than one-third of the world’s broadband users by providing
them with ultra-broadband access.
