This book is about the load-balanced router, a routerarchitecture that is scalable and can guarantee afull capacity. A load-balanced router consists of twostages.

A load-balanced routerdoes not use any centralized scheduler, as mostcurrent router architectures. Therefore, it can scalewhile providing the throughput guarantees needed bynetwork operators. It this book, we show how to implement theload-balanced router using a single passive opticalswitch fabric with no reconfigurations, whilecurrent routers commonly need switch fabrics withfast reconfiguration times. Further, we introduce asimple distributed algorithm that can avoid packetreordering, a common problem of load-balancedarchitectures.

Klappentext
This book is about the load-balanced router, a router
architecture that is scalable and can guarantee a
full capacity. A load-balanced router consists of two
stages. First, a load-balancing stage spreads
arriving packets equally among linecards. Then, a
forwarding stage transfers packets from the linecards
to their final destination. A load-balanced router
does not use any centralized scheduler, as most
current router architectures. Therefore, it can scale
while providing the throughput guarantees needed by
network operators.
It this book, we show how to implement the
load-balanced router using a single passive optical
switch fabric with no reconfigurations, while
current routers commonly need switch fabrics with
fast reconfiguration times. Further, we introduce a
simple distributed algorithm that can avoid packet
reordering, a common problem of load-balanced
architectures. Finally, we present a practical switch
fabric architecture that would enable load-balanced
routers to scale to higher numbers of interfaces. We
conclude by showing that the load-balanced router can
help provide the scalability and capacity guarantees
needed in the Internet.
