SDN ushered in an era of fast open innovation in networking: Those who own and operate networks now take it for granted that they can code, commission or simply download the control plane they need in their network, customizing it to best meet their needs. The ONOS SDN Controller is an example of an open source control […]
Connecting the Data Center: 25G, 100G, 400G+
Server performance and data center network traffic are growing dramatically and the total I/O bandwidth per rack is approaching 5 Tbit/s. New technologies and virtualization are transforming the network architecture within data centers. The 25G, 50G, 100G, 200G and 400G solutions that are being developed to support low cost links use new module form factors, […]
NFV Made Efficient: Living at the Edge
Virtualizing network functions between the network core and customer edge, with dynamic and distributed capability driven by zero-touch automation, is the ultimate goal of service providers seeking to deliver greater flexibility and agility in new revenue-generating services. Configuring, monitoring and maintaining this automation remotely at scale is key, and puts high requirements on both policy-based […]
Delivering OCP for SDN-Enabled Virtualized Data Centers
The telecom industry’s transformation from traditional networking infrastructure to virtualized data centers is driving increasing demand for open hardware solutions. The Open Compute Project (OCP) has provided basis for rack-scale integration of open compute, storage and networking resources in enterprise data centers. However, adapting the OCP model to the telecommunications industry must take into account […]
Trends in Optical Disaggregation
Bandwidth demands continue to grow exponentially and network operators consistently report the need to accelerate innovation cycles and reduce costs across targeted parts of their network infrastructures. One approach is to leverage open white box systems to drive further innovation and cost reductions. Over the past few years, hyperscale data center operators have applied this […]
The Multicore Challenge to Embedded Systems Programming: How to scale with Maintained Performance and Determinism
Multicore technology causes a significant disruption to the embedded software domain and introduces a great challenge to the entire software industry. Much of the existing software needs to be modified to achieve deterministic performance scalability on a multicore processor. 4G wireless network base band processing is a typical example of where scalable multicore solutions are […]
Single-Lambda 100G: Enabling 400GE Data Center Networking
Insatiable demand from Internet Content Providers with hyperscale data centers for network bandwidth is pushing 400GE as the next speed. Cost-effective deployment of 400GE in the data center will require single-laser solutions with PAM4 modulation. By leveraging existing fiber infrastructure, single-lambda 100G solutions enable quadruple face plate densities while providing the flexible deployment model required in […]
Model driven Network and Device Management (NDM) for Virtual Network Functions (VNFs) and IoT services
As today’s telecom functions and IoT services shift to a cloud infrastructure, carriers and service providers have set new requirements for these services and network functions to be delivered as VNFs. These VNFs must be fully managed and capable of providing an integration with third-party MANO (Management and Network Orchestration) architectures. Functionality that has traditionally […]
Get on the Fast Track to NFV
Communication service providers know that evaluating, purchasing, developing and deploying an NFV solution can turn into more than just a lengthy process; it may also prove to be a very costly endeavor. All the more so if a solution which runs perfectly on data center servers now needs to be spun up and executed on […]
Model-Driven Device Management & Control for Cloud, NFV/SDN, IoT, Appliance & Carrier-Grade Deployments With NETCONF & YANG
With the rapid convergence of technologies such as telecom, cloud, IoT and NFV, the need for more capable and heterogeneous device management solutions has become significant. While early standards such as SNMP, coupled with CLI and web interfaces, still remain relevant, a much richer set of functionality is needed in terms of scalability, security and […]
