“…At the heart of the proposed L1-VPN scheme is a shared capacity management algorithm that dynamically runs on a per-link level [5]. The main function of this algorithm is to maintain accurate per-VPN resource levels for all links during resource allocation and de-allocation phases.…”

“…Despite detailed architectural proposals within Internet Engineering Task Force (IETF), no study have considered the design and performance of L1-VPN algorithms, particularly for circuit-switching next-generation SONET (synchronous Optical Network) multi-domain networks. L1-VPN was studied for intra-domain multi-granularity next generation SONET (NGS) networks, with the goal of providing multiple (virtual) "customer-provisioned" networks over a common physical infrastructure [5]. Here customers are assigned set of resources (nodes, link capacities) and are tasked with managing these resources as per their own service needs.…”

Layer 1 virtual private network (L1-VPN) is new emerging framework that allows clients to directly set up logical topologies and provision their own services without deploying expensive network infrastructure. Emerging and current networks are partitioned in different domains in order to implement different associated administrative, management, control boundaries. For carriers operating multi-domain networks, endto-end control is becoming increasingly a critical requirement. This paper presents a novel control scheme for shared Li-VPN operation in multi-domain networks and derives both centralized and distributed variants. The paper also analyzes the performance evaluation of resource management model, namely dedicated and shared L1-VPN. Results showed that distributed control provides better network utilization and shared L1-VPN increases the network utilization.
