....load balancing schemes [DNS, CIS] The latter rely on the translation function of a name to an address, and therefore suffer from the side effects of DNS caching. SLR operates exclusively at the forwarding path of the network layer, and as such provides a more scalable and efficient solution [ANE99e]. 2.2 Requirements Clients require no modifications to take advantage of an SLR enhanced hosting service. However, host computers require some minor modifications in their IP stack in order to be able to handle a large number of virtual addresses in a scalable way. In particular, we allow a ....
....or host for tunneling new connections for this virtual subnet. In addition, the SLR uses an internal or external routing protocol such as OSPF or BGP [MOI98, STE98] to advertise routes to the virtual subnets it has knowledge of. More details regarding the state aggregation scheme can be found in [ANE99e]. 2.4 The PRONTO router We have implemented our scheme on the Pronto (Programmable Networks of Tomorrow) router [HJA99] The Pronto router is a dynamically programmable active router within a Linux kernel that supports programmability at different timescales of activity, ranging from control ....
