Enterprise WAN solutions have evolved from basic hub-and-spoke topologies using leased lines or Frame Relay and ATM to fully meshed MPLS networks. More recently, private, public and hybrid cloud models have emerged. SD-WAN solutions allow enterprises to adopt intelligent branch routers that can support multiple services like application-aware routing and better security. An encrypted overlay creates a unified fabric across networks including private circuits, broadband internet and LTE.

1. Enterprise WAN solutions have changed significantly over the last decade. Basic hub-
and-spoke topologies such as leased lines or Frame Relay (FR) and Asynchronous
Transfer Mode (ATM) architectures gave way to fully mesh MPLS-based solutions. More
recentlyprivatecloud,publiccloudandhybridmodelshavearrived.
A hybrid WAN dynamically supports MPLS, broadband Internet, cellular connections,
and any other transport mechanism available to an enterprise. Hybrid WAN solutions at
the branch office have evolved to include various types of appliances such as firewalls,
intrusion prevention, IP VPN concentrators, WAN path controllers and WAN
optimizationcontrollers.
SD-WAN solution allows enterprises to adopt an intelligent branch router that can
support multiple services like application-intelligent policy-based forwarding/routing,
better security and application performance for new generation of enterprise end-
users. An encrypted overlay creates a unified fabric from a physical underlay that can
includeprivatecircuits,low-costInternetbroadband,andevenLTE.

ALTEN Calsoft Labs NFVOps Framework
Our NFVOps Framework provides an ETSI MANO compliant VNF Manager framework for OpenStack controlled NFVI. The framework can be
used to automate VNF deployment, health monitoring, policy based auto-scaling and remediation for distributed NFV deployments
includingEnterprisevCPE,EnterprisePrivateCloud,TelcocloudandPublicclouds.
NFVOps Framework eases integration with NFV orchestrators, SDN Controllers (e.g. OpenDaylight), EMS/NMS, OSS/BSS and third party
resourcemanagerssuchasVMwarevCenter,AWSCloudFormation,HPECloudServiceAutomation,etc.
Our Virtual CPE (vCPE) Framework provides a rich suite of DPDK optimized high
performance fast path functions that can be readily used to develop Enterprise vCPE
productsusingCOTSx86platforms.
ALTEN Calsoft Labs vCPE Framework delivers high performance line-rate throughput
that scales linearly with number of CPU cores. Its modular architecture offers flexibility
