Network Tuning
This section describes a few ways that can be used to improve performance of a network.
- Active Queue Management (AQM) is a class of router mechanisms for improving perceived network performance by managing buffers intelligently.
- Random Early Detection (RED) is an important example of an AQM strategy.
- Explicit Congestion Notification (ECN) can be used with AQM-performing gateways to signal (light) congestion without dropping packets.
- Differentiated Services can be used to compose various kinds of service assurances and priority systems from simple building blocks
- Integrated Services is an earlier IETF framework for quality of service differentiation using per-flow reservations
- Sizing of router buffers presents a difficult optimization problem, trading off queuing delay against link utilization.
- Buffer Bloat is the name of the issue created by a big buffer size on networks with speeds less than 100 Mbps.
- Network proxies or so-called "WAN accelerators" is a way to speed up transmissions between sites without modifications to end hosts or protocols.
- Finally, some tuning hints specific to Cisco routers.
