Huawei Demos SDN Virtual Transport Service

Huawei demonstrated a transport SDN prototype capable of delivering Network on Demand (NoD) services.

Huawei's SDN virtual transport service solution is based on its Path Computation Element (PCE) architecture.

The goal of the virtual transport service platform is to provide users with multiple modeled virtual topologies through programmable interfaces to meet on-demand virtual network service (such as NoD service) user requirements in real time.

Huawei said its platform can help carriers deliver customized services and deploy value-added services efficiently and flexibly. An intelligent Transport Path Engine (TPE) algorithm ensures dynamic network resource optimization.

The announcement follows Huawei's demonstration of a transport SDN controller prototype launched last year.

SoftCOM is Huawei's end-to-end ICT network architecture based on concepts such as cloud computing, SDN, NFV, and network openness.

The demonstration occurred at the recent Layer123 conference in Bad Homburg, Germany.  In a keynote address at the conference, Justin Dustzadeh, Huawei's CTO & VP Technology Strategy, said Carrier SDN ultimately will be an end-to-end framework spanning Last Mile, Access, Aggregation, Metro & Core, and Data Center equipment. He presented several SDN use cases, including:

  • SDN-based Mobile Backhaul
  • Virtualized Residential Gateways with virtual set-top boxes
  • Traffic Steering for Gi-LANs
  • Cloud IMS
  • SDN-based Transport Network Virtualization

Huawei is also continuing work on its Protocol-Oblivious Forwarding (POF) technology, which is a software-defined networking (SDN) forwarding implementation.  The goal is to leverage the OpenFlow protocol in a programming model where forwarding devices are no longer limited by pre-defined packet protocols or forwarding rules.  Data plane hardware would not be limited by hard­-wired protocol implementations. POF has been prototyped on Huawei's NE5000E Core Router

ETSI's NFV Group Publishes Update

ETSI's Industry Specification Group for Network Functions Virtualisation (NFV ISG) has published its second white paper highlighting progress to date.

The NFV ISG, which will be meeting this week in California, currently has four working groups: Infrastructure Architecture, Management & Orchestration, Reliability & Availability, and Software Architecture.  Altogether, the NFV ISG has grown to over 150 companies, including 28 Service Providers.

The new whitepaper provides an overview of the following topics:

  • NFV Use Cases document describes initial fields of application.
  • NFV Requirements document describes the high level business and technical requirements for an NFV framework including service models. It is a key reference document for the NFV ISG.
  • NFV Architectural Framework document describes the high-level functional architecture and design philosophy for virtualised network functions and the underlying virtualisation infrastructure. By delineating the different constituents and outlining the reference points between them, it paves the way for fully interoperable multi-party NFV solutions.
  • NFV Terminology document is a common repository for terms used within the NFV ISG documents.
  • NFV Proof of Concept Framework document. The NFV ISG has launched a global call for multi-party NFV Proof of Concepts (PoC) to validate NFV approaches. 

The 16-page whitepaper is available online.

IBM Awarded Patent for Cloud Security Technique

IBM has been awarded U.S. Patent #8,539,597: Securing sensitive data for cloud computing.  The technique enables clients to use cloud-based services without risking the release of sensitive data into cloud environments, alleviating security and privacy concerns due to information disclosure or attribution.

IBM said its invention helps overcome security concerns by redacting, removing or replacing sensitive data from records that are being sent to the cloud for processing. It then restores the sensitive data when the records are returned from the cloud.

"Patents like this help to solve real-world security challenges that are inhibiting cloud computing growth," said Josyula Rao, IBM Director of Security Research. "IBM's investment in research and development is producing innovations that will advance the company's cloud computing and security leadership."

CommScope Completes IPO -- Nets $437 Million for Debt Repayment

CommScope completed its initial public offering of 38,461,537 shares of its common stock at $15.00 per share, raising $577 million.

The shares, which are listed on NASDAQ under the ticker symbol "COMM", closed at $14.99 on the first day of trading (Friday, October 25).

The company expects to net approximately $437.3 million after underwriting costs. The company intends to use the net proceeds it receives from the offering, plus cash on hand, to redeem approximately $399 million in aggregate principal amount of its 8.25% Senior Notes due 2019 and to pay related premiums, expenses and accrued interest. J.P. Morgan, Deutsche Bank Securities and BofA Merrill Lynch were lead book-running managers.
