- Abstract
- OXC (Optical Cross-Connect) system is on indispensable network element to realize the all-optical mesh networks, because that supports the increase of link channels and the expansion of an OTN (optical transport network) capacity at low expense. This paper describes architecture of APRS (Automated Connection Provisioning and Restoration Subsystem), which can be applicable various network topologies. Since APRS manages network connections and optical circuits fOr transparent OXC that can be classified by survivability class level, it provides an efficient mechanism for optical connection management. APRS coordinates with SMS (Service Management System) or network services, etc, VPN (Virtual Private Network), VLAN (Virtual Local Area Network), and QoS (Quality of Service), so it can support optical level CoS (Class of Service). And APRS supports an automated connection provisioning that can provide PC (Permanent Connection), SPC (Soft Permanent Connection), and SC (Switched Connection) and supports a dynamic restoration mechanism according to the policy and survivability class level. APRS consists of distributed objects, and then it can be applied in not only the layered-centralized network connection management without control plane but also the distributed network connection management with control plane.
