“…LISP is a pull-based architecture that stores the state in the Mapping System, network entities (e.g, LISP Tunnel Routers) retrieve and cache only locally relevant state on demand. Furthermore, the literature shows that the Mapping System internals can be designed to be scalable [9].…”

LISP: a southbound SDN protocol?

Abstract-The Locator/ID Separation Protocol (LISP) splits current IP addresses overlapping semantics of identity and location in two separate namespaces. Since its inception the protocol has gained considerable attention from both the industry and the academia motivating several new use cases to be proposed. Despite its inherent control-data decoupling and the abstraction and flexibility it introduces into the network, little has been said about the role of LISP on the SDN paradigm. In this paper we try to fill that gap and analyze if LISP can be used for SDN. The paper presents a systematic analysis of the relevant SDN requirements and how such requirements can be fulfilled by the LISP architecture and components. This results in a set of benefits (e.g., incremental deployment, scalability, flexibility, interoperability and inter-domain support) and drawbacks (e.g., extra headers and some initial delay) of using LISP for SDN. In order to validate the analysis, we have built and tested a prototype using the LISPmob open-source implementation.

“…This is the approach followed by the Delegated Database Tree (DDT) based on [9], the Mapping System design used on the current LISP Internet deployment (lisp4.net). On the other hand, some deployments could require a flat name space, this is the case of non-aggregatable data such as character strings.…”

Traditionally, efficient inter-domain data delivery may be implemented either as a network or application layer multicast service. However, while the former has seen little uptake due to prohibitive deployment costs the latter is widely used today, but often without a minimum guaranteed performance. In this paper we present Lcast, a network-layer single-source multicast framework designed to merge the robustness and efficiency of IP multicast with the configurability and low deployment cost of application-layer overlays. The architecture involves no end-host changes and only requires the upgrading of a small set of routers to support the Locator/ID Separation Protocol (LISP), an incrementally deployable enhancement to the current global routing infrastructure. Content distribution over the Internet's core is done by means of a router overlay while within domains, end-hosts interface with Lcast using conventional multicast protocols. The overlay's scalability and topological configurability is sustained by logically centralizing group management. We illustrate the versatility of our solution by designing and assessing the scalability and performance of three management strategies for low latency content distribution. Our analysis is based on large scale simulations supported by realistic user behavior and Internet-like network topologies. The results show Lcast's low management overhead and ability to optimize delivery to meet various operational constraints. Notably, we find that it can deliver traffic with latencies close to unicast ones, independent of overlay size.

“…Where IP clients use the address retrieved by DNS to base their networking connections on, we propose a slightly different solution based on LISP-TREE [21] and its equivalent LISP-DDT [22]. Applications base their communication on the context-related names, while networking instances on either the hosts or gateways near them translate the Interests to their location-aggregated names 7 .…”

Abstract-Information Centric Networking (ICN) paradigms aim at optimizing computer networks for information distribution. Named Data Networking (NDN) and its implementation CCNx propose a promising globally implementable ICN. Routing on names, however, may result in extremely large global routing tables. In this paper, we propose to confine the global routing table size by decoupling context-related names, such as domain names, from names routable within the network. By aggregating routable names to their topological location, the size of global routing tables decreases to the number of Autonomous Systems. Furthermore, mapping context-related names back to locationaggregated names using a directory service eases the process of sharing information on the ICN. The robustness of the network is further increased by employing dynamic multihoming without changing application names.
