Abstract

The functions of a Software Defined Networking (SDN) controller are leveraged to gather real-time network Wide Area Network (WAN) link information, audit the information and then use SDN techniques to adjust configuration based on collaboration best practices. The SDN controller provides real-time network topology information and information about WAN links between collaboration sites. The collaboration applications can then use this information for making up-to-date determinations of WAN link configuration based on best practices.

ABSTRACT

    The functions of a Software Defined Networking (SDN) controller are leveraged to gather real-time network Wide Area Network (WAN) link information, audit the information and then use SDN techniques to adjust configuration based on collaboration best practices. The SDN controller provides real-time network topology information and information about WAN links between collaboration sites. The collaboration applications can then use this information for making up-to-date determinations of WAN link configuration based on best practices.

DETAILED DESCRIPTION

    Enabling a network to have the capabilities to service collaboration media applications is a complex, time consuming and potentially error prone activity. It involves configuring many network elements and ensuring that the configuration among those elements is consistent. In particular, configuring expensive, bandwidth-limited connections (WAN connections) within an enterprise network are critical to the proper function of collaboration systems. High quality media sessions for collaboration require that the underlying data network to be configured properly for Quality of Service (QoS), etc.

    Conversely, the structure of the underlying data network determines how certain collaboration policies (such as bandwidth choices for video, etc.) should be implemented by the collaboration application. Typically this is done by configuring information into the collaboration application that attempts to duplicate the capacities of the actual data

network. This is difficult, static and error prone and most existing collaboration applications cannot duplicate all typical data network configurations.

    Networks deployed by customers are also not usually static, i.e. they are updated from time-to-time (new sites added, network elements updated, WAN links upgraded). These changes to the network infrastructure typically necessitate an updated design (or complete redesign) of how the collaboration application utilizes the network. The complexities described above for deployment of a collaboration application on the network are re-lived each time there is a change made to the underlying network.

    Collaboration network managers often establish best practices for networks to be used for collaboration. Automating the process of assuring conformance to these practices will reduce errors and improve the quality of collaboration sessions.

    Using these best practices, the collaboration application in conjunction with a SDN controller can:

    Identify and learn attributes of links between collaboration locations (bandwidth primarily but also redundancy and alternate routing, virtual local area network (VLAN) configuration).

    Verify capacity based on proposed Unified Computing (UC) deployment and usual UC capacity estimates...
