2. Problem Statements • Plan to provide multi services in common core transport network • Each service has different requirements for the common core transport network • Bandwidth, RTT, Jitter, network topology, BGP/OSPF routes, IP/MPLS,... • To meet these requirements results in an inefficient use of network resources and complex operation in each service and core transport network • A network operator for each service can not create dedicated core transport network’s topology and assign dedicated network resources using current network technology. Core Transport Network for Service A Bandwidth! Service A Internet Service A Internet Core Transport Network RTT! Core Transport Network for Service B Service B Mobile Service B Mobile

3. Vertical Network Consolidation • Vertical Network Consolidation • Each service has a virtual network in a common core transport network • each "service" operator expects to have an isolated virtual network on the backbone that can be managed independently. • In this model, we can provide a network wholesale service without carriers' carriers in RFC4364. • Just one service is affected if routing/signaling process failures on a core router occur VPN VPN Virtual Network 2 Mobile Mobile Virtual Network 1 R1 R3 R2 Core Transport Network Internet Internet R4 R5 R6

4. What we expect in ACTN • Efficient use of core transport network resources • Virtual Network Controller provides an optimal virtual network for each service which meets requirements • Fast deployment of a new service • Virtual Network Controller dynamically provides a virtual network for a new service • Virtual Network Controller may change the existing virtual network for other services to optimize an efficient use of network resources and meet requirements for every services • Control of core transport network by service network operator • Each service network operator can control each virtual network by sending a request to virtual network controller • Service network operator becomes VNO(Virtual Network Operator)

5. Use case:Multi Tenant VNO • Multi-tenant virtual network coordination(VNC) function creates and assigns avirtual network for each service • VNC receives requirements from each service control agent • VNC requests a virtual network for each service to network control(NC) function • NC function reserves the virtual network in core transport network Multi-Tenant VN Coordination Service Control Service Control Request a virtual network Core Transport Network Control Reserve a virtual network (RSVP/PCEP) Service A Internet Service A Internet Core Transport Network Service B Mobile Service B Mobile

6. The requirements for MTVNO • Dynamic Binding of Virtual Network • provide a new virtual network dynamically • Separate Operation of Virtual Network • restrict a control of a virtual network of a service from other service network operator • QoS and SLA • provide a virtual network which meets requirements from a network operator of each service • Virtual Network diversity • provide a diverse virtual network for diversity purpose • Security • restrict a connectivity between different services through the common core transport network

9. Horizontal Network Consolidation • Horizontal Network Consolidation • Create multi-domain topology on the common core transport network • One service or some services accommodate at the dedicated PEs or the shared PEs • In this model, we can’t provide a network wholesale service without carriers' carriers in RFC4364. • All services are affected if routing/signaling process failures on a core router occur Core Transport Network Internet Internet VPN VPN Mobile Mobile
