Open source Istio cloud service mesh reaches 1.0 release

The Google-inspired, Istio open-source project announced its 1.0 release.

Istio is intended to be a service mesh that collects logs, traces and telemetry, and adds security and policy without embedding client libraries. The software offers APIs for integrating with systems for logging, telemetry and policy.

Google describes Istio as a key step toward delivering its Cloud Services Platform. Istio could be used for measuring traffic between services: requests per second, error rates and latency.

Google notes that IBM is a key collaborator and co-founder of Istio, and Lyft’s Envoy proxy is a key component of the project. Datadog, SolarWinds, Sysdig, Google Stackdriver and Amazon CloudWatch offer plugins to integrate Istio with their products. Other companies supporing Istio include Cisco, Red Hat, and VMware.

  • Branded prepaid net customer additions were 91,000 in Q2 2018, down 3,000 from Q2 2017.
  • Branded prepaid churn was 3.81% in Q2 2018, down 10 basis points compared to Q2 2017.


Apstra publishes Intent-Based Taxonomy model

Apstra published an Intent-Based Taxonomy model to help network operators cut through the marketing hype.

“We are introducing a model intended to help CTOs and network operators evaluate and differentiate the maturity of IBN solutions with an objective set of criteria, beginning with Level 0 (low maturity/incomplete) offerings going up to Level 3 (mature/complete) offerings which enable companies to leverage full benefits of IBN approach,” said Sasha Ratkovic, CTO and Founder of Apstra.



Level 0 IBN: Basic Automation

These offerings have the ability to:

  • Generate device configurations from declarative specifications. For example: scripts running Ansible modules or other declarative libraries such as NAPALM.
  • Support a heterogeneous infrastructure.
  • Ingest real-time network status in a protocol- and transport-agnostic way.
  • At this level there is no presence of a single source of truth, which is a fundamental aspect of a mature IBN implementation, as it enables reasoning whether or not the intent has been met.

Level 1 IBN: Single Source of Truth

An implementation classified as Level 1 implements a single source of truth containing the intent and the network operational state. It contains data and state artifacts related to all aspects of a network service lifecycle: design, build, deploy, and validate. Level 1 can give you answers to important questions about the state of your intent and your infrastructure.

Level 2 IBN: Real-Time Change Validation

Building on top of Level 1, Level 2 IBN solution enables you to ask the right questions, at the right time to help assess the impact of business rule or policy changes, as well as the operational status changes and failures in real time.

Level 3 IBN: Self Operation

Does the IBN solution validate and close the loop between the intent and operational state by providing observability, and deliver corrective actions on a path to self-operating networks? This step is impossible to tackle if one has not built solid foundations in Levels 2 and 3.

R&M intros a high-density fiber patch panel for data centers

R&M (Reichle & De-Massari AG) introduced its "Mercury" network patch panel for data centers in the American market.

The high-density fiber platform can house up to 288 LC terminations per 2RU. The company says its design allows data centers to implement the physical network infrastructure in a much more flexible manner. Mercury is stackable in either 2RU or 6RU steps, providing up to 6,912 LC fiber terminations per rack. If duct space is scarce, up to 30 percent of duct space can be saved with the 200μm fiber option.

Mercury is specifically designed for ribbon fiber, which saves up to 50 percent of installation time compared with single-fiber deployments, and which is gradually replacing traditional single-fiber cabling for increased bandwidth, efficiency, and space optimization. Mercury can be configured for 200µm or 250µm fiber given the available duct space. This enables a reliable and advanced cable infrastructure throughout the data center.

"R&M developed Mercury to address the need in the United States for ever increasing need for additional fiber connections, duct space optimization and flexibility," said Dieter Studer, marketing manager, R&M USA Inc. "Mercury allows R&M's U.S. customers to expedite their data center projects with minimized installation time in the secured zone, and to scale when needed with seamless installation of additional panels."
