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

Riverbed is continuing to enhance its Whitewater cloud storage gateways with goal of replacing tape storage with third-party, offsite solutions. The Whitewater platform ingests back-up data into its local data cache that scales to multiple terabytes in size. Whitewater performs deduplication, compression, encryption and other optimization techniques before delivering the back-up traffic over the WAN to a cloud-based storage service. Riverbed said its clients often achieve 10-30x reduction in backup traffic over the WAN, thereby making cloud-based back-ups a faster, easier and lower-cost alternative to tape with offsite warehousing. Data restoration is much faster too since the local cache typically stores a majority of the previous 30 days of backed up data.
Fujitsu has developed new optical amplifier technology with the potential to quadruple the number of splits and double the transmission distance for PON optical access systems.




Research in Motion suffered a third day of disruption to its BlackBerry service with outages and slowdowns expanding to the United States, Canada and corporate networks. RIM's CIO Robin Bienfait began posting regular updates on the crisis, stating that traffic is now moving through the network and that the company hope to restore normal service levels soon. No technical details on the cause of the disruption has been confirmed apart from a switch failure on Tuesday at a data center in the UK.

The network, which uses Ciena's 6500 Packet-Optical Platform, now has 100 Gbps optical backbone connections operational between New York, Washington D.C., Cleveland, Chicago, Kansas City, Denver, Salt Lake City, and Sunnyvale spanning a distance nearly 4000 miles.
