This success story describes the Connectem VCM solution, powered by VMware vSphere®, and the excellent results it has achieved. Introduction Founded in 2011 by industry veterans, the mission of Connectem (http://www.connectem.net/) is to bring the advances of virtualization and cloud computing to the evolved packet core. Connectem’s VCM platform is a unique innovation – one of only a few that has been introduced to the mobile operator infrastructure in many years. The Connectem Virtual Core for Mobile (VCM) solution fundamentally changes the way in which the networks are built, deployed and managed.. With Connectem VCM, carriers can, for the first time, economically address the rapid growth in services, the number of IP endpoints, and the associated signaling. Connectem’s Virtual Core for Mobile Connectem developed and deployed the first ever instance of a virtualized LTE Evolved Packet Core (EPC) running on standard datacenter infrastructure. This solution comes at a time when the telecom industry is yearning for change. For many years, carriers have been saddled with the high cost of proprietary hardware with closed software, and its high operational cost due to complex procedures and the dimensionally-challenged interconnection.

Breakthroughs such as these have the potential to change the economics of deploying new mobile broadband networks. We are very excited to announce these results. — Sachin Kapur, Vice President of Engineering, Connectem PROFILE Industry Global communications systems / software Corporate Headquarters Suite 250, 3160 Delacruz Boulevard Santa Clara, CA 95054 U.S.A. Solution Connectem Virtual Core for Mobile (VCM) solution VMWARE AT WORK VMware vSphere / VMware ESXi x VMware vSphere® 5.5 Enterprise Plus Edition® x VMware® ESXi® 5.5 VMware vCenter x VMware® vCenter Server® 5.5 DEPLOYMENT ENVIRONMENT Primary application Transformation of mobile broadband infrastructure through network functions virtualization (NFV). Recently, new data applications and devices are arriving with increasing frequency from a variety of vendors. They add stress to the underlying network. Adding network capacity faces challenges such as the complexity of point-to-point interconnects and node-based capacity planning, along with assuring availability across those connections. The traditional remedy of vertical node-based capacity growth is proving to be too expensive in terms of both Capex and Opex. In order to address the challenges in packet core networking, Connectem created its virtualized packet core technology called Virtual Core for Mobile. Connectem’s VCM takes advantage of years of innovation and investment from computing and data networking entities such as VMware to enable an elastic, scalable, and robust platform optimized for operational simplicity. By mapping the packet core transaction and activities into basic computing units, Connectem VCM uses the virtualized environment to add and remove capacity dynamically in order to handle peaks and troughs of signaling capacity. The VCM solution manages “signaling storms” in a cost effective and predictable way. The resulting solution has both technical and economic efficiency. With Connectem’s VCM solution, carriers are, for the first time, able to accelerate the growth of rich data services, and build faster mobile networks with unrivalled capacity. This results in a lower unit cost with reduced energy consumption. Connectem’s VCM, Powered by VMware Connectem chose VMware®, a key partner, to power its high performance cloud architecture using the VMware vSphere® 5.5 virtualization and cloud computing platform, with the VMware® ESXi® 5.5 hypervisor. Connectem chose VMware vSphere because it is a preferred, optimal secure, flexible, high performance virtual environment. VMware vSphere increases the consolidation of physical servers, infrastructure, and associated resources. The VMware platform enables rapid integration, the rapid allocation of computing resources, rapid access to those resources on demand, and increased utilization. It facilitates operational efficiencies, including faster response times, immediate access to datacenter resources, extensive security, and simplified management. With VMware, the Connectem VCM solution uses a pool of virtual machines to handle tasks related to underlying activities. For example, signaling activity or packet forwarding. This results in better hardware utilization creating an infrastructure with increased energy efficiency and a lower total cost of ownership (TCO). With VMware’s inherent scale and capacity management capabilities, the VCM solution can effectively lower the operator’s CapEx and OpEx. VMware virtualization improves performance with scaling that delivers the appropriate resources where they are needed most. In addition, it provides for greater flexibility and elasticity to extend and increase resources such as on-demand memory, and to expand resource capabilities.

P AR TN ER SU C C E SS ST OR Y C onnectem® Virtual Core for Mobile, Powered by VMware Unprecedented Scale, Availability, and Performance The Connectem VCM solution has unique architectural attributes that take advantage of modern datacenter tools. The VCM solution delivers unprecedented scale, availability, and performance using low cost, high volume x86 servers. VCM is a cost effective solution that addresses the growing demand in both signaling and data throughput. This solution is capable of addressing elasticity, scale, and service velocity in the largest mobile broadband networks. 10:1 Performance Improvement Compared to Proprietary System Working together, Connectem and VMware engineers recently performed collaborative trials to validate the best way to optimize the efficiency of 4G LTE EPC control plane processing. Using a service-oriented view of EPC functionalities, Connectem chose to use a computational method to map packet core functions. Demand in the network capacity (signaling, bearer, or throughput) is translated to a common computing resource requirement (CPU, memory, I/O, and storage). This enables VCM to add computing resources in units of virtual machines to address the underlying network activity. This testing simulated thousands of attach procedures per second handled by the constituent virtual machines of VCM on a single x86 Xeon™ blade server running the ESXi hypervisor. When compared to traditional offerings, the improvement in performance was dramatic. Processing the same number of attach procedures using an equivalent traditional offering required a total of 10 active processing blades across three different nodes (MME, S-GW, P-GW). The Connectem VCM solution is implemented using highly distributed, stateless components that are managed at a service level on a single server, and allowed to scale independently. On a single machine, the complex interactions between these components limit vertical scalability. Connectem virtualized cohesive sets of components to demonstrate performance by managing horizontal scalability and elasticity. These engineering tests showed optimal server resource utilization on VMware ESXi, with multiple instances of virtual machines running appropriate groups of vEPC components. Ordinarily, distributing these processes on different virtual machines incurs the overhead of inter-virtual machine communication, and this would not be an optimal solution. However, Connectem used the VMware VMXNET3 para-virtualized, virtual network driver to mitigate this issue. SOLUTION BRIEF /3
- 4. P AR TN ER SU C C E SS ST OR Y Connectem® Virtual Core for Mobile, Powered by VMware VMXNET3 allowed the components to reach the required throughput and maintain the performance. This testing confirmed throughput in excess of 30 Gbps with VMXNET3 across the virtual machines. Hardware Consolidation, Resource Management, and Elasticity The Connectem VCM solution provides for the full virtualization of system resources using VMware, including the consolidation of servers, storage, and networking infrastructure. The VCM solution uses VMware infrastructure to enable virtual networking elements that are similar to those used in the physical environment, but with some advanced capabilities. Importantly, Virtual Distributed Switch (vDS) is used to abstract physical network interfaces and provide access-level switching in the ESXi hypervisor. vDS acts as a single switch across all associated hosts that are managed by administrators and it enables virtual machines to maintain a consistent network configuration. In addition, VMware infrastructure also includes virtual network interface cards (vNIC) that enable virtual machines to provide support for VMXNET3 vNICs, VLANs enable virtual networks to join physical VLANs or to support quality of service (QoS) policies. It also includes LBT load balancing, an advanced vDS feature, and Central Management. Network policies on vDS get pushed to the host automatically when the host is added to the distributed switch. VMware optimization includes the use of VMware Tools to gain access into virtual machine operation. vSphere Performance Monitoring and Performance Analysis Tools are used for time- or post-analysis visual performance monitoring, and to collect performance data such as for CPU load, network I/O, memory utilization, disk I/O, and more. The VMware ESXi command line utilities esxtop and resxtop were particularly useful when troubleshooting bottlenecks. Connectem uses VMware virtual machine templates to create preconfigured virtual machines images and configurations. Internal and external deployment of distributed virtual machine templates allowed “snap rollout” of the complete system. VMware® vCenter Server® provides for centralized monitoring, including aggregating all resident virtual machines and hosts. vCenter uses patented analytics and an integrated approach to dramatically simplify management tasks, such as to provide sufficient CPU and memory resources. vCenter proactively ensures health, efficiency, and compliance with IT policies. The Connectem solution running on the VMware platform delivers excellent carrier-grade performance. It provides for the dynamic allocation of resources using an elastic, highly available cloud architecture, powered by VMware. SOLUTION BRIEF /4 © 2014 VMware Corporation. All rights reserved.
