“…One is the data-driven scheme and the other is the control-driven one [2]. For example, the former scheme is implemented in "IP switch [6]" and Toshiba's "CSR (Cell Switch Router) [3]" and the latter one is adopted in Cisco's "Tag Switching [7]" and IBM's "ARIS (Aggregated Route-Based IP Switching) [11]". So far, we have analyzed the performance of LSR by focusing on the processing delay of IP packets in Layer 3 routing kernel in case of the data-driven scheme [5], in which we treated real time traffic and assumed the routing kernel with buffer of infinite length.…”

LSR(Label Switching Router)s in MPLS (Multiprotocol Label Switching) networks map arriving IP flows into some labels on Layer 2 switching fabric and establish LSP(Label Switching Path)s. By using LSPs, LSRs can not only transmit IP packets fast with cut-through mechanism, but also solve traffic engineering issue to maximize resource utilization in the whole MPLS networks. So far, we have analyzed delay performance of LSR by focusing only on the real time traffic transmission. In this paper, we will consider the case where non-real time traffic arrives at LSR as well as real time traffic and analyze those packet loss rate under the assumption that the cut-through transmission is applied only to real time traffic. Furthermore, we discuss the bandwidth allocation policy and the buffer dimensioning to meet the requirement with respect to both delay for real time traffic and loss probability for non-real time one, and show the guide for QoS provisioning in MPLS networks.

“…Wormhole IP o~ er {Connectionless) ATM is a hardware-only IP routing method, and hence differs fundamentally from the software methods that are in use today for routing IP over ATM--or for using ATM under IP [13]. Software methods have a number of costs, overheads, and associated delays that are not present in wormhole IP over ATM: 1) a very large number of VP/VC labels are consumed; 2) until a flow has been recognized, the first few packets in the flow are not switched; and 3) new connections for new flows are established in software, with corresponding high delays.…”

Abstract--High-speed switches and routers internally operate using fixed-size cells or segments; variable-size packets are segmented and later reassembled. Connectionless ATM was proposed to quickly carry IP packets segmented into cells (AAL5) using a number of hardware-managed ATM VCs. We show that this is analogous to wormhole routing. We modify this architecture to make it applicable to existing ATM equipment: we propose a low-cost, single-input, single-output Wormhole IP Router that functions as a VP/VC translation filter between ATM subnetworks. When compared to IP routers, the proposed architecture features simpler hardware and lower latency. When compared to software-based IP-over-ATM techniques, the new architecture avoids the overheads of a large number of labels, or the delays of establishing new flows in software after the first few packets have suffered considerable latencies. We simulated a wormhole IP routing filter, showing that a few tens of hardware-managed VCs per outgoing VP usually suffice. We built and successfully tested a prototype, operating at 2 x 155 Mb/s, using one field programmable gate array (FPGA) and DRAM. Simple analysis shows that operation at 10 Gb/s and beyond is feasible today.Index Terms--Connectionless ATM, gigabit router, IP over ATM, routing filter, wormhole IP, wormhole routing.

“…Consequently, a number of concepts to carry IP traffic have been suggested. Transmission of IP over ATM has been a standardisation target [2,7] and has inspired vendors to develop competing solutions, e.g., IP switching, IP/ATM, ARIS and Tag switching [7,8]. IETF has started to develop a harmonising concept to be called Multi-Protocol Label Switching (MPLS) and, additionally, has founded a working group to study service differentiation mechanisms to accelerate routing and switching of IP packets [6,14].…”

The evolving multimedia services are foreseen to be delivered to customers over heterogeneous transport networks. The ATM technology has been considered as the most obvious choice, but other transporting concepts have also been studied and entirely new ones suggested, especially, for IP based communications. Diversity in transporting concepts implies that network nodes, such as switches and routers, should connect to different kinds of networks. This introduces the need to support multiple switching disciplines in a single switching fabric and, additionaIJy, a clear need for interworking. As a solution to the emerging problem, this paper introduces the concept of multidiscipline switching to integrate different switching systems into a compact fabric and to offer interworking between the connected networks.
