Simplifying ongoing network management has been a customer concern for decades, but in recent years it has turned into a rally cry as customers struggle to reliably support the demands that all their users, devices, and services are placing on their networks. Getting a handle on what is going on and effectively troubleshooting issues in the network has always been a challenge, one that appears to only be getting more complicated.
A recent survey by the Enterprise Strategy Group found that 72 percent of organizations are planning on increasing their monitoring and security tools over the next 36 months. Each tool provides a different glimpse into a different aspect of the network, often for different teams in an organization. What’s needed is a more cohesive approach to monitoring the network: a multi-tenant solution that can weave together all the different “panes” that meet all the different requirements of all the different groups who need to understand what is going on in the network.
One of the key use cases of software-defined networking (SDN) is tied to monitoring — specifically tap aggregation and, to some extent, a subset of the features provided by the network packet broker (NPB) vendors today. In particular, the tapping use case is popular because it is non-invasive and does not impact any mission-critical paths in the network, yet it is important to keeping a network infrastructure healthy and running optimally.
Early commercial solutions in the tapping space from SDN vendors such as Big Switch have shown strong early traction. To better understand why tapping is one of the first SDN use cases and an ideal first step to SDN, as well as the capabilities of Big Switch’s solution combining SDN and bare-metal switches with its tapping application, check out the white paper, “SDN Monitoring Fabric: Tap Sharing Use Case.”
We believe that solutions such as this one that can handle five-tuple filtering, packet replication, overlapping policies, and gradual scale out, as well as offer fine-grained, multi-tenant control, are a step in the right direction toward providing the visibility and monitoring capabilities required to address customer concerns and network demands.
