Telecom Pros Discuss Challenges of 5G Network Slicing

by Angela Whiteford Angela Whiteford No Comments

As we’ve discussed in previous posts, 5G promises to let communications service providers (CSPs) ‘slice’ the network to accommodate a wide range of applications with very different reliability, quality of service, security, latency, and throughput requirements. To accommodate such services, CSPs will create individual network slices on a multi-tenant, multi-operator network platform. Slices will be orchestrated and assured end to end through automated closed control loops using intent-based management, analytics and policy. CSPs will support on-demand network slicing on a per-customer or per-application basis.

To support CSPs, the Affirmed Virtual Slice Selection Function (vSSF) makes it easy to build network slices across any network. vSSF, inserts into existing networks without requiring configuration changes, and delivers a centralized “one-touch” function for allocating resources by a variety of attributes (device type, service type, customer ID, location, time-of-day, and more) to meet the needs of specific services.  The vSSF is the industry’s first solution to provide network slicing over legacy, virtualized, and multi-vendor 5G network environments.

With regard to 5G challenges, including network slicing, TM Forum Network Functions Virtualization /IT transformation conducted a survey of sixty-one telecom professionals at fifty-two companies, including CSPs and suppliers. The resulting report, Trends Analysis report 5G: Is platform the killer use case? confirms the widespread belief that for CSPs to find the best way forward, the key factors are 5G, network functions virtualization (NFV), and software-defined business models for networking and cloud-based platforms.

The study shows when it comes to network slicing, sixty percent of respondents see end-to-end management as their biggest issue. The study also showed:

  • A top concern of a third of the CSPs and suppliers is the availability of operating and business support systems (OSS/BSS) that can accommodate a wide range of innovative business models with multiple parties, using a variety of pricing strategies.
  • Twenty-nine percent of CSPs and twenty-six percent of suppliers are worried about organizational issues. Telco operations teams are typically arranged vertically around specific product groups, which is inadequate for platform-based network slicing models.
  • About fifteen percent of CSPs and eleven percent of suppliers are concerned about a lack of edge-computing resources for 5G network slicing, believing that there is not enough computing power at the edge today to analyze network usage patterns and ensure quality of service.

With Affirmed’s “5G Ready” solutions supporting network slicing today, mobile operators can dramatically improve the profitability of their existing services now. By combining the vSSF with innovations such as the Affirmed Service Automation Platform, operators can rapidly deploy network slices and new revenue generating services in order to reduce time-to-market and operational costs by as much as 90%. Adding the Affirmed Virtual Probe, operators receive real-time analytics on individual slices and services, enabling them to improve service quality, reduce network support costs and identify new service opportunities.

5 Network Requirements for the 5G Network Revolution

by Angela Whiteford Angela Whiteford No Comments

In order to create a 5G network we must transform three things: the radio access network, the core network, and the service creation layer. Radio access standards and available spectrum are still works-in-progress—but we have a good understanding today of the five core network requirements for 5G:

Create a Common Composable Core

Create a common composable core to deliver a controlled and secure experience across access technologies and manage connectivity/mobility for mobile devices. The 5G core also needs to scale dynamically while reducing cost and complexity. A composable core decouples the user and control planes, moving services and applications closer to the network edge. Communications service providers (CSPs) can affordably achieve high bandwidth, low latency requirements with unlimited scale and flexibility.

“Slice” the network to Support Different Services

In a 5G network, CSPs will need to slice their network resources into many different types of services, each with unique requirements around quality of service, security, latency, etc. HD videoconferencing in a telemedicine application will have very different session requirements than a wireless machine-to-machine device communicating its hourly status. CSPs must support network slicing on-demand on a per-customer or per-application/use case basis.

Optimize for the Internet of Things

The Internet of Things brings billions of connected wireless sensors that will share space on the same network as consumer and enterprise data traffic. Preventing millions of devices from impacting subscriber services requires a network architecture that can efficiently handle high-bandwidth downloads, high-bandwidth uploads, and high-density/delay-tolerant communications.

Support Creation of New Mobile Services

Increased network intelligence and analytics will allow service providers to create new services that drive business decisions and improve the overall subscriber experience. Real-time insights can be gleaned from session control, subscriber events and subscriber data to drive smarter network planning and provisioning.

Simplify Network Operations and Management

CSPs face the challenge of how to build more intelligent networks to handle more volume and more types of traffic without escalating costs. On the wireless access side, leveraging existing Wi-Fi networks and short-range access points instead of radio access network (RAN) towers can mitigate the cost of mobile broadband. Within the network, CSPs use virtualization and the cloud to reduce capex costs, while service automation, orchestration, and network analytics will drive opex costs down.

The promise of NFV is to be able to manage core telco applications with the agility and scale of the cloud. But how do we convert a legacy application into a “Cloud Native” application? On June 13 at the Open Platform to Accelerate NFV (OPNFV) conference in Beijing, China, a one-day Cloud Native VNF development workshop will take us on a journey from traditional monolithic VNF to OpenStack cloud native container VNF, with practical advice from experts who have walked this path.

The comprehensive session list covers automation, monitoring, componentizing, telemetry fault management, container orchestration, and much more, led by speakers from Red Hat, Dynatrace, NEC, China Mobile, and others.

Dejan Leskaroski, Sr. Product Manager at Affirmed Networks will cover the “state and storage” topic, including how to “fix” apps that use filesystem storage, considerations for managing database as a service, a comparison of shared filesystems vs. object storage, and issues around handling sessions.

Unpacking What’s Next in Network Composability at the Big Communications Event

by Angela Whiteford Angela Whiteford No Comments

The “composable core” is all about creating new services quickly and easily. As a leader in virtualization, Affirmed Networks has been working with operators such as AT&T, Vodafone, Etisalat and more. Affirmed CEO, Hassan Ahmed, shared his insights on the current state of network composability with open-integration mechanisms at the Virtualization Track at the Big Communications Event held in Austin, TX in May.

The ability to dynamically compose microservices independent of the VNF’s original structure opens up a world of possibilities for service providers:

  • They can enhance existing services. For example, a service provider might wish to add network monitoring capabilities to each of its core network elements. Instead of deploying a physical or virtual probe to monitor each gateway or element independently, a service provider could move the probing function into a container and re-create those network elements with the probing function built in to the service.

  • They can adapt to IoT opportunities. The Internet of Things (IoT) will place unique demands on service provider networks—and present exciting new opportunities for revenue-generating services. A cloud-native architecture has an inherent advantage here because it allows service providers to move functions closer to the network edge (to reduce latency for applications such as healthcare device monitoring), use external storage to reduce costs (versus stateful VM-based storage) and deliver multi-tiered load balancing at exceptional scale.
  • They can create new network elements. The arrival of 5G and IoT will create the need for new network elements such as the Cellular IoT Serving Gateway Node (C-SGN). By assembling the right microservices and functions in a cloud-native architecture, service providers can dynamically create VNFs to serve as the C-SGN or other needed roles in the network.

Creating a cloud-native network is a journey. It is one that can be accomplished faster and with fewer risks when the right architectural foundations are in place. If your network vendor doesn’t have a clear path to cloud-native capabilities in the products they sell today, then you don’t have a clear path to the cloud either.

At Affirmed, the cloud has been an integral part of our vision from the very beginning. The solutions that we sell today, such as our evolved packet core, have been designed to accommodate cloud-native transformations simply and easily. More importantly, these solutions allow service providers to deploy a proven NFV platform today that can address current network needs—more capacity, lower cost, higher performance—while providing a seamless migration path to micro-services and cloud-based delivery models.

Don’t Miss This Red Hat Summit Session on Containers, Microservices and the Cloud-native Telco

by Angela Whiteford Angela Whiteford No Comments

Will you be at the Red Hat Summit in Boston? If so, be sure to attend our session on how Telco and NFV Cloud Service Providers can move from monolithic software architectures to cloud-native microservices.

Affirmed Networks’ James Logan, Director of Cloud Infrastructure Software and Technology will join Red Hat’s Anita Tragler and Marc Curry to shed light on this evolution, ranging from what a Cloud Native architecture consists of, to how CSP networks benefit from moving the virtualized VM based deployments to a mix of VMs, Containers in VMs and Containers on bare metal.

To meet the needs of 4G-LTE/5G, IoT and never-ending appetite of mobile applications, Telco 3GPP standards and Virtual Network Function vendors are driving “cloud native” deployments that are lightweight, scalable, and resilient. Moving NFV clouds to containers requires high performance container networking, multi-tenancy, container security, orchestration and integration.

Gaps in the Container ecosystem will have to be addressed for VNFs, including orchestration limitation, managed multi-tenancy, multi-interface, network security, high performance datapath, performance tuning.The session with Red Hat and Affirmed Networks will cover customer requirements for vEPC, vCPE, 5G NG-Core, vIMS, vGiLAN services, and , potentially, a demonstration of the vEPC on Red Hat OpenStack in Containers.

Please join Jim at the Boston Convention and Exhibition Center on Thursday, May 4, at 4:30 PM in Room 153A for session S103944 – “Are you being served? Containers, microservices and the cloud-native telco.
