Drivers of Change in the Metro
Over the last few years, we have seen a major change in telecom services and the way that these services are being used. This has been driven by three main factors:
What Can Telecoms Learn from the Bayeux Tapestry?
People have been telling stories with pictures since early man painted scenes of animal hunts on cave walls. These stories often recorded military victories, such as in Egyptian hieroglyphs and battle tableaus featuring chariot riding pharaohs, Assyrian palace bas-reliefs depicting monumental sieges, and the war columns of the Roman emperors Trajan and Marcus Aurelius. These were the YouTubes of their day.

The original Path Computation Element Protocol (PCEP) work dates from the early 2000’s, with the first IETF RFC (4655) being made informational in 2006—which means PCEP predates the time when SDNs were “cool.” PCEP was originally, because of the increasingly complex nature of computing Traffic Engineering (TE) paths through (primarily), Service Provider (SP) networks. Three specific developments drove the design, standardization, and deployment of PCEP:
God Box Concept
When it comes to examples of aiming high and failing on a grand scale, systems that combine layers 0 to 3 in one solution (a.k.a. God Boxes), are among the first examples that come to mind. However, whether due to lack of Packet features, missing price points or organizational hurdles, they came and went. And I know that as a vendor one should be very careful to not leave the impression that you are actually trying to build one (again).
But the concept is still intriguing…
Today, more than 50% of the world’s population lives in cities. That number is expected to grow to 66% by 2050! In an era with smartphones, smart cars and smart homes, isn’t it about time we start building smarter cities?
That isn’t really a question, is it? We can argue about the technology, the protocol, the topology, the software, but at the end of the day, we are all looking at our transport networks and making sure it’s working the way it’s supposed to, serving our needs and our customers’ demands.

Last time, we explored the advantages of deploying end-to-end MPLS and why it is better to push MPLS TP and not IP/MPLS into the metro.

IT challenges for utility companies are diverse and getting increasingly complex with the growing demand for energy, the implementation of the smart grid and two-way communication, the introduction of new energy sources that are spread out and the need to comply with security requirements. These are only a few of the issues that burden utilities’ communication needs and requirements.
We’re back from Ethernet Expo Americas (EENY), Light Reading’s popular event covering the hot topic of Carrier Ethernet networking technologies and services. Over the past couple of years, this event has also started to cover more and more optical-related topics, which is yet another sign of the growing convergence in the market between packet and optical. It was just announced that the event, now in its seventh year, set new records for registration and industry involvement. Over 130 service providers and cable operators from more than 25 different countries attended the event, which featured a record 35 speakers from service provider, cloud provider and enterprise organizations.
