Current high-volume, high-availability data centers and content distribution networks use clusters of Web servers or caches to achieve scalability and reliability. In such environments a front-end dispatcher (or router) directs incoming client requests to one of the server machines. The request-routing decision can be based on a number of criteria, including server load, client request, or clie...

are computed by averaging over 100 replications and are reported in Table 1. Clearly, the PB method performs well and less well for large k and small k values, respectively, because of the choice of the “moderately big” model. Evidently, the estimator μ̂full estimates μ well for small k values but poorly for large k values, depending on the true model. In terms of the accuracy of prediction, Êrr...

IPv6 rapid deployment on IPv4 infrastructures (6rd) builds upon mechanisms of 6to4 to enable a service provider to rapidly deploy IPv6 unicast service to IPv4 sites to which it provides customer premise equipment. Like 6to4, it utilizes stateless IPv6 in IPv4 encapsulation in order to transit IPv4-only network infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6 prefix of its own in...

Most requests on the Web are made on behalf of human users, and like other human-computer interactions, the actions of the user can be characterized by identifiable regularities. Much of these patterns of activity, both within a user, and between users, can be identified and exploited by intelligent mechanisms for learning Web request patterns. Our focus is on Markov-based probabilistic techniq...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract The purpose of this document is to define terminology specific to the benchmarking of multicast IP forwarding devices. It builds upon the tenets set forth in RFC 1242, RFC 2285, and other IETF Benchmarking Methodolo...

A mechanism is defined for use by message servers in transferring data between hosts. The mechanism, called the MSDTP, is defined in terms of a model of the process as a translation between two sets of items, the abstract entities such as 'strings' and 'integers', and the formats used to represent such data as a byte stream. A proposed organization of a general data transfer mechanism is descri...

This document discusses deployment issues and describes requirements for successful deployment of mobile email that are implicit in the IETF lemonade documents. Table of

This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract In this document, we discuss location privacy as applicable to Mobile IPv6. We document the concerns arising from revealing a Home Address to an onlooker and from disclosing a Care-of Address to a correspondent.
