Hybrid-Access: A New and Ultrafast Path for bringing Broadband to Underserved Customers

Hybrid-Access: A New and Ultrafast Path for bringing Broadband to Underserved Customers

What can you achieve by integrating an industry standard protocol with a powerful telecom network server node and powerful Intel Home Gateway network processor?

How about a fast path to enhanced broadband access for underserved customers? Intel DSLTE_illustration_1 and Ericsson are using standards-based technology to improve the broadband experience of consumers and optimize carrier network utilization. The collaboration will help telecom carriers meet requirements for fast broadband services on the edge of widely distributed network service regions.

In demonstrations at Broadband World Forum 2015, the two companies are showing an end-to-end access solution based on Multipath Transmission Control Protocol (MPTCP). The hybrid solution aggregates the bandwidth of both DSL and LTE transmission links to multiply data rates and create a single, powerful broadband pipe between the network service node and customer’s Broadband gateway / router.

Benefit for User and Telcos

The global average broadband access speed is 3.9 Megabit per second. A growing number of network operators face the challenge to upgrade these underserved regions and customers in a cost-effective way to higher broadband speeds. Use case scenarios show that for example a “20 UP / 20 Down Mbps data pipe” would perfectly serve the broadband needs of today’s cloud based services, IPTV or modern office scenarios. The combination of fast VDSL and LTE enables operators to reach this performance goal with minimum investment as they smartly re-use their existing network infrastructure. Carriers combining mobile and fixed line network access can even create one broadband pipe that reaches up to 300 Mbps aggregated data throughput with high reliability.

The Intel / Ericsson hybrid access approach adds an LTE link to a DSL gateway, allowing operators to boost broadband access performance. At the same time operators significantly increase their network reliability for fallback scenarios. As a result, combining DSL and LTE opens up new business opportunities for Operators.DSLTE_Illustration_2_V2

For the broadband subscriber, the benefits are obvious: Superfast broadband connection on existing infrastructure, without any construction works. Users simply need to plug in their new broadband routers at home and are ready to go.

Technology helps to bring Broadband to Underserved Regions

The MultiPath Transmission Control Protocol (MPTCP) is a Linux kernel protocol that is currently in the standardization process with the Internet Engineering Task Force (IETF) (RFC6824). Ericsson is adding the protocol to the feature set of its MultiService Proxy (MSP) network node. Concurrently, Intel is incorporating the technology in a new DSLTE™ Home Gateway reference design based on the AnyWAN™ GRX 350. Intel AnyWAN platforms can be easily configured to support any incoming WAN data link, including all variants of Cable, DSL, FTTx and LTE. That simplifies design and implementation of product families for OEM/ODM customers and helps ensure that carriers can source solutions from multiple Customer Premises Equipment (CPE) vendors.

“With three years of experience as a provider of DSLTE gateways, we know that telecom providers recognize the importance of improving the experience of end-users on the network edge,” said Dan Artusi, Vice President and General Manager of Intel’s Connected Home Division. “The Intel DSLTE reference design enables suppliers to quickly develop products to fill this need for carriers. Developing this Hybrid Access platform with Ericsson as a world leader in communications technology brings tremendous value to carriers. They can optimize the performance of their network assets and finally offer best user experience and ultrafast broadband connection to the subscriber.”

Hybrid DSL and LTE is a cost-effective way to upgrade DSL for subscribers that only have access to low data rates today and live in areas where it is too expensive for the operator to upgrade network infrastructure (using VDSL, bonding, vectoring, or fiber). It’s a superb complement to the broadband mix of network operators as it extends the reach of broadband service with no new investment in existing DSL or LTE infrastructure.

Ericsson’s Multiservice Proxy (MSP), a part of the Media Delivery Network solution, is the link between mobile networks and Internet services and gives the operator a rich suite of tools with which to optimize and assure data delivery. Ericsson is the leader in video and data delivery solutions. The Ericsson MSP is deployed with over 150 Media Delivery customers to date.

The Intel/Ericsson collaboration is the first open, software-based end-to-end hybrid solution to increase broadband capability and optimize carrier network utilization using existing infrastructure. Development projects with select customers are starting now, with general commercial availability planned for the first half of 2016.

About Christoph von Schierstaedt

I am Communications Manager for Intel. I started at a Radio Station in Bavaria where I learned a lot about journalism, I worked for agencies and newspapers. Later (2003) I entered the "other side" of Media and Communications, when joining Infineon Technologies AG as Manager Internal Communications. After that I joined the Media Relations Department and became Spokesperson for Infineon. In 2009 I joined a fast and nimble Company for Broadband Semiconductors: Lantiq! For five years I was responsible for Communications at this great company, which recently got acquired by Intel. And here I am :-)
