SDN Automation and Orchestration (Cloud Control)
Contrail Cloud Platform releases are aligned with OpenStack community releases to maintain API compatibility and strong community support. Automated resource provisioning for configuration and operation of computing, storage, and networking resources needed by cloud applications minimizes manual intervention and improves operational
The attributes of Cloud Networking: Scalable, Low Latency, Open APIs, Programmable Management, Self-Healing Resiliency.
Software-defined networking (SDN) is an umbrella term encompassing several kinds of network technology aimed at making the network as agile and flexible as the virtualized server and storage infrastructure of the modern data center.The goal of SDN is to allow network engineers and administrators to respond quickly to changing business requirements.
Contrail Networking interoperates with OpenStack cloud orchestration
platform to enable system-level automation and orchestration. It reduces
the friction of migrating to cloud architectures by providing a
virtualized networking layer that seamlessly delivers switching,
routing, and networking services (security, load balancing, VPNs, etc.)
over an existing physical network. It also provides API compatibility
with public clouds like Amazon Web Services (AWS) for seamless workload
provisioning in hybrid environments.
For service providers, Contrail Networking automates network resource provisioning and orchestration to dynamically create highly scalable virtual networks and to chain a rich set of Juniper or third-party virtualized network functions (VNFs) and physical network functions (PNFs) to form differentiated service chains on demand. Integrated with a cloud management platform such as OpenStack, Contrail Networking enables the agile creation and dynamic scaling of service instances with high availability and reliability. Contrail Networking also makes it really simple to onboard network functions onto the platform without requiring any API integration or modifications to third-party service software.
Switching and Routing: Hypervisor forwarding plane provides line-rate routing and switching in a multitenant virtualized environment that is completely decoupled from the underlying physical fabric switches.
Load Balancing: Load balancing is built right into the hypervisor’s forwarding plane for balancing traffic across application tiers or network services.
Security and Multitenancy: The use of L3VPN to create virtual networks inherently provides a secure multitenant environment, where virtual networks cannot talk to each other without policies. The Contrail Networking vRouter has built-in distributed firewall capabilities that allow users to define security policies between virtual networks. The security policies can specify additional virtualized network services such as the Juniper Networks Firefly Perimeter application-aware firewall; and distributed threat prevention using Juniper Networks WebApp Secure, which can be spun up between virtual networks.
Elastic, Resilient VPN: L3VPN, E-VPN, and site-to-site IPsec are all delivered in software.
Gateway Services: Contrail interoperates with most routing equipment that supports L3VPN or E-VPN with the appropriate data encapsulation standards, including Juniper Networks MX Series 3D Universal Edge Routers to seamlessly connect to legacy workloads and non-virtualized physical services.
High Availability: All Contrail Networking components are made highly available and offer active/active redundancy. Each Contrail Networking VRouter is connected to a set of control planes and gets the same routing table and access control lists (ACLs).
Analytics Services: Rich visualization and diagnostics of virtualized and physical networks enable real-time and historical infrastructure analytics that can be consumed through RESTful APIs. Users can also view live packet capture of traffic between virtual networks.
API Services: RESTful API for configuration, operation, and analytics provides seamless integration with OpenStack or service provider OSS/BSS systems. This includes Virtual Private Cloud (VPC) API compatibility for seamless deployment of applications in a hybrid environment (e.g., private cloud and public cloud/AWS).

1.Centralized network provisioning
Software defined networks provide a centralized view of the entire network, making it easier to centralize enterprise management and provisioning. For example, more VLANs are becoming part of physical LANs, creating a Gordian knot of links and dependencies. By abstracting the control and data planes, SDN can accelerate service delivery and provide more agility in provisioning both virtual and physical network devices from a central location.
2.Holistic enterprise management
Enterprise networks have to set up new applications and virtual machines on demand to accommodate new processing requests such as those for big data. SDN allows IT managers to experiment with network configuration without impacting the network. SDN also supports management of both physical and virtual switches and network devices from a central controller; something you can’t do with SNMP. SDN provides a single set of APIs to create a single management console for physical and virtual devices.
3.More granular security
One of the advantages of security defined networking that appeals most to IT managers is centralized security. Virtualization has made network management more challenging. With virtual machines coming and going as part of physical systems, it’s more difficult to consistently apply firewall and content filtering polices. When you add in complexities such as securing BYOD devices, the security problem is compounded.
The SDN Controller provides a central point of control to distribute security and policy information consistently throughout the enterprise. Centralizing security control into one entity, like the SDN Controller, has the disadvantage of creating a central point of attack, but SDN can effectively be used to manage security throughout the enterprise if it is implemented securely and properly.
4.Lower operating costs
Administrative efficiency, improvements in server utilization, better control of virtualization, and other benefits should result in operational savings. Although it is still early to show real proof of savings, SDN should lower overall operating costs and result in administrative savings since many of the routine network administration issues can be centralized and automated.
5.Hardware savings and reduced capital expenditures
Adopting SDN also gives new life to existing network devices. SDN makes it easier to optimize commoditized hardware. Existing hardware can be repurposed using instructions from the SDN controller and less expensive hardware can be deployed to greater effect since new devices essentially become “white box” switches with all the intelligence centered at the SDN controller.
Cloud computing is here to stay and it is evolving into a unified infrastructure. By abstracting cloud resources using software defined networking, it’s easier to unify cloud resources. The networking components that make up massive data center platforms can all be managed from the SDN controller.
7.Guaranteed content delivery
The ability to shape and control data traffic is one of the primary advantages of software defined networking. Being able to direct and automate data traffic makes it easier to implement quality of services (QoS) for voice over IP and multimedia transmissions. Streaming high quality video is easier because SDN improves network responsiveness to ensure a flawless user experience.
The specific advantages of software defined networking will vary from network to network, but there are benefits from network abstraction and the agility it offers for network administration and automation. The best way to get the most out of SDN is to assess the network components and infrastructure to determine if SDN can help address issues such as resource availability, virtualization, and network security. Software defined networking isn’t the right approach for every network environment, but when there are clear benefits, SDN could be just the solution you need to optimize your data center.
Software-defined Wide Area Network (SD-WAN) product provides a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, LTE and broadband internet services – to securely connect users to applications.
An SD-WAN uses a centralized control function to securely and intelligently direct traffic across the WAN. This increases application performance, resulting in enhanced user experience, increased business productivity, and reduced costs for IT.
Application Delivery Control
Application Delivery Controller products provide load balancing, application acceleration, web application firewall, SSL termination, and security along with seamless access to applications. ADCs, also called app delivery controllers, may be delivered in three form factors: hardware appliances, virtual appliances (the software extracted from legacy hardware) and software-only load balancers.
