Escrow reservations is a well-known synchronization technique, useful for inventory control, that avoids conflicts by taking into account the semantics of fragmentable object types. Unfortunately, current escrow techniques cannot be used on generic “commodity” servers because they require the servers to run the type-specific synchronization code. This is a severe limitation for systems that req...

Social network applications are inherently interactive, creating a requirement for processing user requests fast. To enable fast responses to user requests, social network applications typically rely on large banks of cache servers to hold and serve most of their content from the cache. In this work, we present DynaSoRe: a memory cache system for social network applications that optimizes data ...

Public information systems offering access to the network community can be divided into two groups: those with stateful protocols and those with stateless protocols. Evolving client-server protocols like the Hypertext Transfer Protocol (HTTP) of the World-Wide Web (W3) are stateless. In this case the reaction of the information server depends on the request only. To access the server, special c...

This paper focuses on the problem of accessing interactive information servers ("interactive sessions" in W3-terminology, e.g. an existing library information system) directly with a W3-browser instead of opening an additional viewer (e.g. a terminal emulation program). IDLE is a language designed to describe the user interface of interactive information servers in a way that allows automatic t...
