“…The DNS specification defines a means for increasing availability of any distributed service, by using the DNS NAPTR [9] and DNS SRV [6] records. These methods assume that, for load balancing purposes, behind a given DNS name there exist more physical machines, such that: (1) if one or more of the machines are too loaded, the message sent to the considered URN (Universal Resource Name) should be treated by a less loaded machine; and (2) if one or more of the machines are down, even if it happens for maintenance reasons, the message sent to the considered URN should still be treated by a machine that is currently running.…”

A critical problem in a distributed system is the load of each of its individual components, which, if too large, threatens the availability of the whole system. A solution for system availability is decentralizing its components by using peer-to-peer networks. For such networks, we define in this work a scalable, transparent strategy for locally balancing the load of the individual peers, based on the intrinsic dynamicity of such networks, thus impacting as little as possible the availability and functionality of the system as a whole. We perform preliminary evaluation for our solution, too, concluding that the overhead added by our load balancing distributed algorithm is small and acceptable, considering the availability advantages it brings with it.

The current Internet architecture does not properly handle multi-homed hosts, since each interface of a multi-connected end-host terminal generally appears as a completely different node. The lack of transparency about the multi-homing degree of end-hosts brings even more problems when those hosts are mobile. On the one hand, in our view the combined use of local hierarchical locators and global flat identifiers for both end hosts and networks is important to reach an efficient control of multi-homing and mobility. On the other hand, when planning to use flat global identifiers for networks we must consider an increased number of access autonomous systems. To target that scenario, this paper presents a novel addressing scheme and a global lookup system based on multi-level flat identifiers, which operate between the Internet domain naming service and its routing system. The proposed mechanism allows Internet access providers to deploy networks that may not be physically adjacent to each other, without having to reveal their topological location. This is done by grouping access networks of the same organization in the same virtual organizational zone. Virtual zones aim to hide the control of multihoming and mobility from the Internet core. The second major goal of employing virtual zones is to bring closer to the end-host the decision about the most suitable access network and terminal interface to be used. This allows the exploitation of end-hosts interface diversity and local path diversity in a more efficient way.

“…In order to discover directory services, multicast can be used for an intranet, such as in SLP and Jini, but well-known directories are often assumed for the Internet, such as in UDDI. In addition, Dynamic Host Configuration Protocol (DHCP) (Droms, 1997) can be used to get directory service information in localarea networks (Perkins and Guttman, 1999), and DNS SRV (Gulbrandsen et al, 2000) can be used to obtain directory service information for given DNS domains (Zhao et al, 2004).…”

This paper presents three new mechanisms for the Service Location Protocol (SLP): mesh enhancement, preference filters and global attributes. The mesh enhancement simplifies Service Agent (SA) registrations and improves consistency among Directory Agents (DAs) by defining an interaction scheme for DAs and supporting automatic registration distribution among peer DAs. Preference filters facilitate processing of search results (e.g., finding the best match) in SLP servers (DAs and SAs) to reduce the amount of data transferred to the client for saving network bandwidth. Global attributes allow using a single query to search services across multiple types. These mechanisms can improve SLP efficiency and scalability and support advanced discovery such as discovering multi-access-point services and multi-function devices. We expect that these techniques can also be applied to other service discovery systems.
