Survey Cloud monitoring: A survey

A variety of proposals call for a new Internet architecture focused on retrieving content by name, but it has not been clear that any of these approaches are general enough to support Internet applications like real-time streaming or email. We present a detailed description of a prototype implementation of one such application -- Voice over IP (VoIP) -- in a content-based paradigm. This serves as a good example to show how content-based networking can offer advantages for the full range of Internet applications, if the architecture has certain key properties.

Caching in information centric networking: A survey

Many systems employ caches to improve performance. While isolated caches have been studied in-depth, multi-cache systems are not well understood, especially in networks with arbitrary topologies. In order to gain insight into and manage these systems, a low-complexity algorithm for approximating their behavior is required. We propose a new algorithm, termed a-Net, that approximates the behavior of multi-cache networks by leveraging existing approximation algorithms for isolated LRU caches. We demonstrate the utility of a-Net using both per- cache and network-wide performance measures. We also perform factor analysis of the approximation error to identify system parameters that determine the precision of a-Net.

Approximate Models for General Cache Networks

Technology advances in both computations and wireless communications have made it economically feasible for manufacturers to collect data from all the cars in order to monitor their operations and detect any potential problems. However to make this a reality requires a new architecture that can effectively handle vehicle mobility, intermittent connectivity, and data security, as well as scale to large number of vehicles. In this paper we address these design challenges by exploring the direction of Named Date Networking (NDN) (aka CCN1). We evaluated our design, dubbed DMND, through simulations in Qualnet. Our results show that, when data publishers (vehicles) are stationary, more than 99% of collection requests can successfully pull data packets back; even when vehicles move at a high speed of 40–50 meters per second (89.48–111.8 miles/hour), DMND can still retain its high efficiency of 97% of data replies. In contrast, under the same simulation experimental setting, the request-reply ratio of MobileIP drops from 97.9% for static publishers to 9.6% when publishers are moving at a speed of 10–20 meters/second (22.37–44.74 miles/hour).

DMND: Collecting data from mobiles using Named Data

The existing Internet ecosystem is a result of decades of evolution. It has managed to scale well beyond the original aspirations. Evolution, though, highlighted a certain degree of inadequacies that is well documented. In this position paper we present the design considerations for a re-architected global networking architecture which delivers dissemination and non-dissemination objects only to consenting recipients, reducing unwanted traffic, linking information producers with consumers independently of the hosts involved, and connects the digital with the physical world. We consider issues ranging from the proposed object identifier/locator split to security and trust as we transition towards a Network of Information and relate our work with the emerging paradigm of publish/subscribe architectures. We introduce the fundamental components of a Network of Information, i.e., name resolution, routing, storage, and search, and close this paper with a discussion about future work.

Design considerations for a network of information

A method for a client node (D100) to access an information object (102) located at a node (D500) of a secured network (120) via a network of information (100) wherein information objects (102) are identified by information object identities (IDObj, ID'Obj) and wherein nodes are identified by locators (LGW, LObj), wherein the following is performed at a routing node (D102): - receiving from the client node (D100) an information object identity related to the information object (102), - sending the information object identity to a resolving node (D400) of the network of information (100), the resolving node (D400) being capable of initiating a procedure for sending to the routing node (D102) a locator of a gateway node (D200) interfacing the network of information (100) and the secured network (120), - receiving the locator of the gateway node (D200), - sending a request for the information object (102) to the gateway node (D200) according to the locator, - receiving the requested information object (102) from the gateway node (D200), and - sending the information object (102) to the client node (D100).

A key distribution scheme for networks of information

Cloud computing is making it possible to separate the process of building an infrastructure for service provisioning from the business of providing end user services. Today, such infrastructures are normally provided in large data centres and the applications are executed remotely from the users. One reason for this is that cloud computing requires a reasonably stable infrastructure and networking environment, largely due to management reasons. Networking of Information (NetInf) is an information centric networking paradigm that can support cloud computing by providing new possibilities for network transport and storage. It offers direct access to information objects through a simple API, independent of their location in the network. This abstraction can hide much of the complexity of storage and network transport systems that cloud computing today has to deal with. In this paper we analyze how cloud computing and NetInf can be combined to make cloud computing infrastructures easier to manage, and potentially enable deployment in smaller and more dynamic networking environments. NetInf should thus be understood as an enhancement to the infrastructure for cloud computing rather than a change to cloud computing technology as such. To illustrate the approach taken by NetInf, we also describe how it can be implemented by introducing a specific name resolution and routing mechanism.

What Networking of Information Can Do for Cloud Computing

New technologies as well as new ways of using network services are rapidly changing the Internet's landscape. These developments will have far-reaching implications for the architecture of the networks of the future. However, the current Internet design is plagued with a number of fundamental limitations, which makes its use as the sole basis for the networking applications of the future questionable. We believe that the Future Internet must allow the co-existence of diverse network designs and paradigms, both new and old, to remain open to innovation and meet the challenges of the future. In this paper, we propose to use network virtualization, embedded in an architectural framework, to achieve this goal and to lay the foundation for the deployment of novel concepts such as content-centric networking.
