128 Technology Delivers SD-WAN the Right Way
Software-defined wide area networking (SD-WAN) is a hot networking trend because it replaces traditional WAN routers and supports multiple transport technologies like MPLS and internet. SD-WAN also allows load sharing of traffic across multiple WAN connections making it more efficient.
But a new white paper based upon market research conducted by CIMI Corp. says that the current thinking around SD-WAN falls short of realizing the technology’s potential. The paper, “Software-Defined WAN in the Age of Virtualization” — identifies the requirements that are essential to fulfilling the technology’s real mission.
Specifically, the white paper stresses the importance of having a flexible edge element that delivers a Service Centric Fabric in the SD-WAN environment— a recent necessity that has not been addressed by most SD-WAN providers.
Requirements for building a Service Centric Fabric —and moving SD-WAN forward in the real world—are:
- Session Awareness—The “session” that bounds a message context has to be treated as a whole
when disconnecting and reconnecting, exercising firewall protection, or doing load balancing. Absent session awareness, chaos ensues.
- Explicit Logical Name Support— If IP addresses are what a user or resource are known by, then changing them changes who the user/resource is. The use of a logical name is fundamental to address mediation because it establishes user identity outside the IP address space.
- Application Service Awareness—SD-WAN needs to support meaningful application prioritization so that they are useful in conjunction with virtualization and cloud computing.
- SD-WAN-as-a-Service Model—A software-based SD-WAN solution that can be deployed on standardized servers, on cloud servers, or in edge appliances is a more versatile approach.
- Self-Federating—A good SD-WAN solution must be able to federate all of the global policy, naming, and addressing elements through the entire WAN automatically.
According to the white paper, most vendors seek to support these areas, but few actually offer much beyond the features that are intrinsic to any baseline SD-WAN implementation. The exception is the SD-WAN solution from 128 Technology, a Session Smart™ router—that delivers an SD-WAN solution that aligns precisely with the future pathway that virtualization and cloud computing is taking, and that path is one every business will take over time.
