| SD-branch is a single, automated, centrally managed software-centric platform that replaces or supplements an existing branch network architecture. A natural successor in the evolution of software-defined wide area networks (SD-WANs), SD-branch simplifies the process of branching networks by collapsing multiple software-defined network functionalities, including routing, onto a single platform. SD-branch technology relies upon: - A virtualized internet protocol (IP) services platform that provides cloud-like elasticity, service chaining and programmability.
- A broad set of virtual network functions (VNFs) to deliver extensive networking and security IP services.
- A centralized management framework that allows integrated control, management, analytics and workflow.
Networking the remote or branch office (ROBO) is a critical, yet challenging, element for most centralized information technology (IT) organizations. SD-branch offers advantages in terms of rapid deployment (branch-in-a-box), lower hardware costs and operational expenditure (Opex) benefits. Other benefits of SD-branch technology include: - Improved operational agility.
- Reduced need for skilled support and maintenance professionals on site.
- Centralized control of a branch office's network architecture through a single pane of glass.
- Smaller hardware footprint.
- Lower power consumption.
It is expected that many organizations will phase out their existing branch routers in favor of SD-WAN packages over the next few years and customers will have the option to buy SD-branch services with support for broader network features, including SD-WAN, routing, security and Wi-Fi. For organizations choosing managed SD-WAN from a service provider, options will be defined by the service provider. While still in its emerging stages, vendors involved in creating SD-branch products and services include Cisco, VMware, Dell, Nokia, Juniper Networks, HPE Aruba, Cradlepoint, Citrix, Silver Peak, VMware, Talari and Versa Networks. |
