Cisco Tetration Targets Pervasive Visibility with Forensics

Cisco unveiled its new Tetration Analytics solution for deep, real-time visibility into packet flows across a data center -- every packet, every flow, every speed.

Cisco Tetration Analytics gathers telemetry data from the ASICs on-board Cisco Nexus 9000 switches and/or from low-overhead software sensors in servers. It then applies machine learning techniques using analytics software running on Cisco UCS C220 servers to addresses critical data center operations such as policy compliance, application forensics, and whitelist security. REST APIs are used to drive a WebGUI.

Cisco Tetration Analytics can continuously monitor application flows in real-time, sending out instant alerts when flows deviate from established behavior. The solution also tracks and analyses historical flows, providing forensic analysis of what happened on the network at certain points in time. Cisco claims 10s of billions of events are searchable in seconds. The big picture is to deliver a "single pane of glass" for all data center activity.

Cisco said continuous monitoring and analysis are key to simplifying operational reliability, ensuring zero-trust operations in automated data centers. The Tetration Analytics could be used in conjunction with Cisco's Application Centric Infrastructure (ACI) architecture to automate policy enforcement through a Cisco APIC. It could also be used in brownfield data centers with the software sensors in the servers.

“Gaining much deeper visibility into the data center and automating actionable analysis across a company’s infrastructure marks a critical technology advancement in building secure digital business models like cloud, mobile and IoT,” said David Goeckeler, senior vice president and general manager of Cisco’s Networking and Security Business Group. “We believe the insights we gain from  applications and the data center overall will enhance existing software solutions and drive the future development of new advanced software that will improve business operations, efficiency and customer experiences.”

Cisco has implemented Tetration in its own network, collecting billions of data points over a short period of time. The company said it has been able to reduce operational expenses by 70% while also gaining the ability to untangle application dependencies on hardware infrastructure.

NEC Carries Record 34.9 Tbps over 6,300km of Fiber

NEC has demonstrated a transmission capacity of 34.9 terabits per second (Tbps on a single optical fiber over a distance greater than 6,300 km.

The results, which were presented earlier this year at OFC 2016 in California, broke previous the spectral efficiency record for transoceanic transmission of 7.1 bit/s/Hz, achieving 8.3 bit/s/Hz using the C-band spectrum. This is a 16.9% improvement on the previous record.

NEC said this level of capacity comes very close to the Shannon limit, which is the fundamental spectral efficiency limit of optical communications. In fact, the demonstration came within 0.5 decibels (dB) of the theoretical maximum value.

"We are proud to have come so close to Shannon's cornerstone of communication theory," said Toru Kawauchi, General Manager of the Submarine Network Division at NEC Corporation. "NEC's research and development teams will continue to explore the limits of even greater subsea capacity, flexibility, and cost-effectiveness."

Technical University of Denmark Hits 43 Tbps Optical Transmission

Researchers at the Technical University of Denmark (DTU) have achieved an optical transmission speed of 43 terabits per second ( 43 Tbps) using a single laser and a single fiber.

The demonstration used a new type of optical fiber (developed by NTT) that contains seven cores (glass threads) instead of the single core used in standard fiber.

DTU noted that its researchers have previously helped achieve the highest combined data transmission speed in the world—an incredible 1 petabit per second—although this involved using hundreds of lasers.

CANARIE and Starlight Test 300G at 8QAM with Ciena

CANARIE, a vital component of Canada’s digital infrastructure supporting research, education and innovation, and the StarLight International/National Communications Exchange Facility Consortium completed an optical transport trial that carried 300 Gbps capacity using the latest coherent optical modulation available via Ciena’s WaveLogic 3 Extreme chipset.

Specifically, the trial carried 150 Gbps per wavelength with 8QAM (quadrature amplitude modulation) on a live research network that connects Ciena’s labs in Ottawa with StarLight’s Chicago-based R&E communication services exchange facility -- a distance of more than 1,440 km.

Ciena said 8QAM modulation means more flexibility for the network operator, providing higher capacity than QPSK, and greater optical reach than 16QAM. All three programmable modulations will be generally available on Ciena’s any-haul Data Center Interconnect (DCI) Waveserver this summer.

Twelve provincial and territorial network partners, together with CANARIE, collectively form Canada’s National Research and Education Network (NREN).
