Sizing Router Buffers (Extended Version)
All Internet routers contain buffers to hold packets during times of congestion. Today, the size of the buffers is determined by the dynamics of TCP’s congestion control algorithm. In particular, the goal is to make sure that when a link is congested, it is busy 100% of the time; which is equivalent to making sure its buffer never goes empty. A widely used rule-of-thumb states that each link ne...

متن کاملSimulation studies on router buffer sizing for short-lived and pacing TCP flows
Traditionally, the size of router buffers is determined by the bandwidth–delay product discipline (normal discipline), which is the product of the link bandwidth and average round-trip time (RTT) of flows passing through the router. However, recent research results have revealed that when the number of flows is sufficiently large, the buffer size can be decreased to the bandwidth–delay product ...
متن کاملEnhanced Buffer Router Design in NOC
This paper presents an advance router design using enhanced buffer. The design provides advantages of both buffer and bufferless network for that two cross bar switches are used. The concept of virtual channel (VC) is eliminated from the previous design by using an efficient flow-control scheme that uses the storage already present in pipelined channels in place of explicit input virtual channe...
متن کاملRecent Results on Sizing Router Buffers
Today all Internet routers are built with buffers that hold packets in times of congestion. These buffers can typically store between 250ms to one second worth of data. According to a widely used “rule-of-thumb”, a link needs a buffer of size B = RTT × C, where RTT is the average round-trip time of a flow passing across the link, and C is the data rate of the link. For example, a 10Gb/s router ...
