E-VPN and PBB-EVPN Take Data Center Interconnect to the Next Level

Tina-lamBy Tina Lam, Product Manager

MPLS based Layer 2 VPN has been around for over 10 years since the inception of IETF Pseuduowire Edge to Edge (PWE3) Working Group. Many drafts and standards have been added, since then, to address different applications and to improve scale and convergence in different topologies. L2VPN as a whole is widely deployed in both service providers and enterprises, from Ethernet services, to fixed and mobile convergence, to enterprise campus layer-2 transport.

Recently, one emerging driver that has been picking up a lot of momentum is to use L2VPN for Data Center Interconnect (DCI). Data centers are often situated in different locations, to be geo-redundant for the purpose of workload mobility and business continuity. At the same time the physical location of the data center has to be transparent to users and to applications. Hence the need for layer-2 connectivity between sites. While Ethernet over MPLS (EoMPLS) and Virtual Private LAN Service (VPLS) have been used for this purpose, DCI presents new requirements and challenges not fully addressed today.  To keep the data center always on, and to utilize all the resources and links as efficiently as possible, data centers need all-active redundancy and load balancing. The technology should be as simple as possible to provision and manage Read More »

Cisco CPAK Helps Win Best 100G Optical Product

Cisco CPAK 100G LR-4 Transceiver

Although we introduced the Cisco CPAK 100G pluggable transceiver back in March at OFC/NFOEC, many people hadn’t yet seen our CMOS photonics technology from our acquisition of Lightwire back in 2012. As a result we had a lot of interest at the WDM Monaco event this week to learn more about the solution capable of lowering the space, power, and complexity of deploying 100 Gbps interfaces by up to 70%. So much interest in fact that we won the “Best Optical Product – 100G” award!

The March of the IPv6 Internet

gunter_vandeveldeBy Gunter Van de Velde, Sr Technical Leader, NOSTG Engineering

It has been a year since the World IPv6 Launch and in that year the global usage of IPv6 has more than doubled. Where traditionally it is believed that there is no IPv6 traffic on the Internet is now shown differently! The reality of real existing user traffic demonstrates the progress of the next generation of the Internet. During the World IPv6 Launch a year ago there was about 0.64% of Internet traffic carried over IPv6, while right now about 1.35% of the Internet traffic is carried over IPv6. That is nearly double and experts believe exponential growth is expected over the next couple of years.

Another data-point is the readiness of the service providers regarding IPv6. On the Internet there are about 44,470 Autonomous networks announcing one or more IPv6 prefixes into the global routing system. A year ago only about 13.7% of them were announcing IPv6 prefixes. That number increased to 16.1% resulting in 7.168 networks out of the 44.470 that are announcing IPv6 prefixes right now.

How Are You Weathering Industry Storms? Five Ways To Help SPs Turn Disruption into Transformation

Service providers (SPs) have been wracked by wave after wave of disruption, creating new winners and losers on every front. Traditional carriers continue to look for ways to make up for lost voice revenues; over-the-top (OTT) players have redefined the ways video is delivered and consumed; exponential growth in mobile data traffic devours network capacity without creating comparable revenue; and new cloud services are transforming IT consumption and challenging old operating models. The industry is changing with whiplash speed—leaving service providers scrambling to get ahead of the next wave.

For years, the Cisco Internet Business Solutions Group has engaged with global and regional service providers to help them navigate and seize the opportunities afforded by industry disruptions. Now, as part of Cisco Consulting Services (CCS), we have identified key industry areas where SPs have transformative opportunities for new services, operations, and business models.

Five Areas of Opportunity for SP Growth and Transformation

Based on Cisco’s own market sensing of trends, tracking of customer behaviors and industry inflection points, and strategy engagements with leading SPs around the world, Cisco Consulting Services has developed unique expertise to help SPs address their challenges and capitalize on opportunities. We are specifically focused on transformative engagements with SPs in five key areas—helping them identify and address the strategic questions they need to answer to be successful: Read More »
