The Powerful Session2Topology (S2T) Correlation Engine
For each session, the Session2Topology™ engine creates a uniquely correlated view. NetSocket’s technology provides a multi-layer mashup. For the first time, a single pane of glass provides a correlated view of signaling control, network, and media layers and how all three of these layers are impacting the end-user experience.
NetSocket has a rich intellectual property portfolio and has been granted 12 patents with 7 more in process.
A Revolutionary Approach
NetSocket's Session2Topology correlation engine differs radically from previous attempts to deliver IP service assurance. Unique aspects of the Session2Topology correlation engine include:
- S2T works in real time to create a service assurance mashup, providing a dynamic ‘map’ of the network onto which media, signaling, and network information is correlated.
- S2T provides a software solution, not hardware. Software is more flexible and less expensive than earlier approaches to IP service assurance. Enterprises are better able to leverage existing investments in networking equipment.
- S2T monitors the network without imposing any burden on the deployed network nodes, such as routers; it passively participates in the routed network using standard IP routing protocols.
Session2Topology Correlation
It is a simple concept—but one that has been difficult to realize until now—that anchors NetSocket’s user-centric IP service assurance solution.
Historically, the signaling layer, the routing/network layer, and the media layer (actual voice or video packets) in a communications network have been architected and managed as separate entities. This was done for the best of reasons: no critical, latency-sensitive services were carried over the IP network. There was no need for a legacy service manager to know how the IP network routed packets for best effort services such as web browsing, email, or file transfers. Critical, latency-sensitive services such as voice were carried on dedicated circuits that guaranteed the connection as well as the quality of the conveyed information.
It is dramatically different with the advent of voice over IP (VoIP) and extended to a multitude of services including video conferencing, telepresence, and collaborative applications such as unified communications. Now, the organizations responsible for managing these services are exposed to the constantly changing nature of IP networks. Ensure end users of real-time voice and video services enjoy the high-quality experience they expect requires completely new solution suite. Now, it is essential for these service managers to know the impact of the IP network on all the services they are delivering. Session2Topology correlation is the first and only technology able to address this need.
As the name suggests, Session2Topology technology automatically correlates the real-time state and changes in the IP network to the individual sessions being carried through that network. In real time, the NetSocket solution knows the exact hop-by-hop path of any session and can identify what network event has, or is, impacting that session. This same knowledge can proactively alert the service manager to changes in network configuration that might impact the traffic on the network. The Session2Topology correlation engine accomplishes all this without adding any burden to the IP network itself, and without relying on proprietary, single-vendor tools.
Big-picture Benefits
With the Session2Topology engine powering real-time IP service assurance solutions, network operators can see, in real time, how sessions traverse their networks – and manage the resources used in the process, also in real time. Real world results are:
- Identify and resolve issues quickly, effectively, and proactively
- Maximize network performance
- Reduce costs
- Improve end users' quality of experience
- Boost user productivity
- Increase business value for organizations deploying real-time IP services
