. These drivers lie between TDI transports and NDIS drivers. To an NDIS driver, an NDIS intermediate driver looks like a TDI transport; to a TDI transport, an NDIS intermediate driver looks like an NDIS driver. NDIS intermediate drivers can see all network traffic taking place on a system because the drivers lie between protocol drivers and network drivers. Software that provides fault tolerant and load balancing options for network adapters, such as Microsoft's Network Load Balancing Provider, are based on NDIS intermediate drivers.
Network Monitor also includes a number of other features, such as capture triggers and filters, that make it a powerful tool for troubleshooting network problems.
quality of service (QOS) guarantees. Video conferencing, media streaming, and enterprise resource planning (ERP) are examples of applications that require good network performance. QOS allows an application to specify minimum bandwidth and maximum latencies, which can be satisfied only if every networking software and hardware component between a sender and receiver supports QOS standards such as IEEE 802.1P, an industry standard that specifies the format of QOS packets and how OSI layer 2 devices (switches and network adapters) respond to them.
RSVP signaling functionality is removed in Windows XP and Windows Server 2003. While the RSVP service still executes, it serves only as a conduit between applications and traffic control components.
