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, Virtual Managed
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
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
Complex VNFs include
multiple VMs that are orchestrated as a single entity with dependencies between
Elastic Services Controller provides IPv6 support on OpenStack for:
Controller provides IPv6 support for northbound interface (for example, NFVO to
VNFM), and southbound interface (for example, VNFM to VNF). However, the
following pre-requisites must be met:
computing is set up and configured for ipv6, including the endpoints (that are
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.
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.
