VCM is the first mobile infrastructure software, designed to use the computing units efficiently in a virtualized environment. Unlike legacy infrastructure that has a high cost to deploy and a high cost to run,VCM is inherent scalability allows any-size deployment and incremental growth. It achieves unprecedented performance and independent scaling in signaling, throughput and storage. VCM supports 3GPP interfaces for roaming and interworking with legacy network and can function as complete EPC.



  • VCM is a software based virtualized EPC running on a set of virtual machines. With its service oriented architecture, VCM dynamically allocates computing resources based on service usage requirements with linear scalability.
  • While being a fully virtualized solution, VCM is not dependent on any specific support from virtualization layer (Hypervisor) or Hardware platform (as long as it is x86 based platform). The reference system Connectem recommends to run our VCM software is as follows:
  • • Hypervisor: ESXi, KVM
  • • OS: Linux CentOS (extendable to support any Linux variant
  • • OS: Linux CentOS (extendable to support any Linux variant
  • • Memory: 256 MB
  • • NIC: 80Gbps
  • • SSD: 800GB
  • • Storage: 2TB
  • With this reference system, the following KPI is supported. This number is calculated with all the users actively transferring data and signaling messages and with HA.
  • • Transaction messages per second: 100,000
  • • Subscribers (SAUs): 4,000,000
  • • Simultaneous bearers: 5,000,000
  • • Total user plane throughput (Gbps): 80
  • VCM uses internal load balancers creating Telecom grade resiliency and availability. The failure of VMs does not result in any loss beyond the loss of the transient messages at those VMs.
  • VCM is fully compliant up to 3GPP Release 10 specifications for the relevant functions and interfaces.
