“…Switching type incompatibilities(e.g., wavelength, waveband and fibre channel at layer 1, Ethernet, Fast Distributed Data Interface (FDDI) and cell switching (ATM) at layer 2, (Generalized) Multi-Protocol Label Switching and Internet Protocol (IP) at layer 3) can exist at various layers. Interface incompatibilities(e.g., 1 GE Ethernet can be encapsulated into VC-3-21v SDH, VC-4-7v SDH, STS-1-24c SONET, or STS-3c-7v SONET) imply possible adaptation and deadaptation problems [18]. Rate incompatibilities(e.g., 1, 10, 40, or 100 Gbps) imply the need for data-rate conversion.…”

a b s t r a c tTransporting Big Data requires high-speed connections between end-hosts. Research and educational networks typically are state-of-the-art networks that facilitate such high-speed user-created network connections, possibly spanning multiple domains. However, there are many different high-speed optical data plane standards and implementations, and vendors do not always create compatible data plane implementations. These technology incompatibilities may prevent direct communication between domains and therefore complicate the configuration of connections. However, some domains may have adaptation capabilities that can lift the technology incompatibility constraint in establishing paths between incompatible domains. Within this context, we address two problems, namely: (1) how to model the technology incompatibilities of multi-domain multi-layer networks, and (2) how to optimally establish paths in such networks. We introduce the inclusion of the information of the supported technologies and adaptation capabilities of each domain and inter-domain link in our model. We subsequently propose technology-aware routing algorithms for finding the shortest feasible path in a multi-domain multi-layer network.

“…With multi-layer paths, technology adaptation must be considered throughout the path finding process as a constraint. Recently, several papers have demonstrated results on the design of mechanisms and protocols for both intra-and interdomain path computations [15,34]. A comprehensive comparison of different interdomain models for path provisioning appears in [35], and key open issues are outlined, including interdomain topology exchanges, routing, and QoS and reliability of paths, for which no scalable solution yet exists.…”

“…This functional model is based on International Telecommunication Union (ITU) G.805 [13] with the addition of capability information. The use of NDL to represent the complex multi-layered GLIF resources has been demonstrated for the creation of a single-layer interdomain lightpath [14,15]. This effort is now going through standardization in a new OGF working group called Network Markup Language working group (NML wg) [17].…”

A new framework for GLIF Interdomain Resource Reservation Architecture (GIRRA)

et al. 2010

Many existing and emerging Scientific highend applications (E-science) require end-to-end circuits interconnecting Grid resources for large data transfers. A few advanced networks, mainly National Research and Education Networks (NRENs), such as Surfnet, National Lambda Rail and Internet 2, now provide mechanisms for end-users to reserve and provision lightpaths via middleware referred to as Network Resource Mangers (NRMs). Although, some progress has been made in automated intra-domain lightpath services, inter-domain lightpath provisioning still requires manual intervention and presents several key challenges such as scalability of topology information exchanged, consistency and scalability of information model, security of access to the resources, hybrid networking and multi-layer lightpaths, and accounting and billing. In this paper, we describe a new architectural framework called Global Lambda Integrated Facility (GLIF) Interdomain Resource Reservation Architecture (GIRRA) with the goal to provide an integrated response to these challenges. We propose a new approach to model GLIF network domains and GOLEs as virtual switches and to describe their behavior, functionality, policy capabilities, and topology aggregation. We define an inter-domain path computation model to determine paths that meet constraints and access policy restrictions. We propose a security framework for authentication and authorization of users and a model for accounting and billing that aims to provide easy and secure access to the resources. Key aspects of the GIRRA solution are that it focuses on the inter-dependence between different challenges of interdomain path provision, and it is built around already existing solutions for intra-domain resource provisioning.
