Huawei introduced its H-MPLS (Hybrid-Multiprotocol Label Switching) prototype unified bearer solution for simplifying VLAN (Virtual Local Area Network) planning within an access network and extending 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, TDM, Ethernet and IP with MPLS encapsulation. Huawei said that unlike traditional MPLS, its 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. Moreover, 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 Dr. Frank J. Effenberger, Huawei’s leader of optical access research, “The label distribution method is already standardized, and has negligible impact to the cost or complexity of PON access systems.�?
Huawei noted that the technologies within Huawei’s H-MPLS solution have been accepted under the ITU-T standard for GPON/XG-PON. http://www.huawei.com
