Cisco Elastic Services Controller (ESC) is a Virtual Network Functions Manager (VNFM), which performs life cycle management
of Virtual Network Functions (VNFs). ESC provides agent-less and multi vendor VNF management by provisioning virtual services,
and monitoring their health and load. ESC provides the flexibility to define monitoring rules, and associate actions to be
triggered based on the outcome of these rules. As a VNFM, in addition to the typical life cycle management operations, ESC
also supports automatic VM recovery when a VM fails and performs automatic scaling in and out functions. ESC fully integrates
with Cisco and other third party applications.
-
As part of the Cisco Orchestration Suite, ESC is packaged with Cisco Network Services Orchestrator (NSO), and available within
Cisco Solution, Managed Services Accelerator Solution (MSX).
-
As a standalone product, ESC is available as a Virtual Network Function Manager for several Cisco VNFs such as CSR1K, ASAv,
WSA and many others.
ESC is deployed in a virtual machine within OpenStack, VMware vCenter, KVM or AWS and manages its VNFs in a Virtual Infrastructure
Manager (VIM).
ESC fully integrates
with Cisco and other third party applications. As a standalone product, the
Elastic Services Controller can be deployed as a VNF Manager. ESC integrates
with Network Services Orchestrator (NSO) to provide VNF management along with
orchestration. Elastic Services Controller as a VNF Manager targets the
virtually managed services and all service provider NFV deployments such as
virtual video, WiFi, authentication and others.
ESC can manage both
basic and complex VNFs . Basic VNFs include a single VM such as a vFW, vRouter
and others.
Complex VNFs include multiple VMs that are orchestrated as a single entity with dependencies between them.
IPv6 Support
Elastic Services Controller provides IPv6 support on OpenStack for:
Elastic Services Controller provides IPv6 support for northbound interface (for example, NFVO to VNFM), and southbound interface
(for example, VNFM to VNF). In order to support both northbound and southbound IPv6 concurrently, the following pre-requisites
must be met:
-
OpenStack cloud computing is set up and configured for ipv6, including the endpoints (that are ipv6 based).
-
The OpenStack cloud computing must contain a Controller, endpoints, and a few Compute hosts, with an ipv6 management and
os_api based networks.
-
The ESC default security group rules support the IPv6 traffic.
 Note |
When you are deploying a VM, you can attach an out-of-band port of an IPv6 subnet to a VM. However, if you are deleting this
VM, you cannot attach the same IPv6 address to another VM due to a known OpenStack issue.
