“…Authors in [10] proposed a physical-layer based solution for local customer internetworking in TDM-PONs. In this solution, using optical switches, a TDM-PON is virtually divided into two independent sub-networks (a separate broadband access for conventional access service and the other for local customers).…”

Abstract-In this paper, we propose a novel energy efficient solution for TDM Passive Optical Networks (TDM-PONs), which is a widely used access network technology, to facilitate local customer internetworking. Here, our prime objectives are to ensure traffic latency among different customers connected through TDM-PON and maximize energy saving performance of Optical Network Units (ONUs), which are TDM-PON equipment situated at customer premises. To do so, we devise a novel sleep management protocols for ONUs. In our proposal, when some ONUs need to exchange traffic, they maintain sleep mode as a group in order to reduce traffic latency among the customers attached with those ONUs. To date, considering traffic forwarding between access and core network entities, researchers have come up with several solutions to manage sleep mode in ONUs in order to improve PON energy saving. However, to the best of our knowledge, how ONUs can manage sleep mode and at the same time satisfy latency requirements while managing data flows among them has been paid little attention. The effectiveness of our solution is validated and compared with other alternative approach by simulation. Simulation results demonstrate that proposed solution reduces inter-ONU traffic delay noticeably compared to other solution while providing satisfactory energy saving performance of ONUs.

“…Therefore, a simplified LAN that is overlaid on the existing PON with high flexibility is required for the intercommunications amongst the customers in the PON. By comparison, emulating pointto-point links amongst customers directly on the optical layer in the PON can effectively overcome several drawbacks (Chae et al, 1999;Chae et al, 2001;Nadarajah et al, 2005;Tran et al, 2006a;Wong et al, 2004). Compared to the higher layer LAN emulation schemes, an optical layer LAN emulation can also be provided whereby the LAN traffic is physically redirected back to the ONUs without the use of higher layer bridges or routers located at the CO.…”

“…Hybrid orthogonal modulation formats are also used to differentiate the private and public communications [38,43,44]. In addition, specific sub-carrier bands [29,30] or time slots [26,27,34,35,37] can be assigned to the different types of connections.…”

Such high splitting loss from the double-pass SC is overcome in schemes proposed in [26], [27] and [28], whereby each ONU is configured to connect to the SC via two distribution fibers, allowing VPN traffic to traverse the SC only once.

We review recent progress on all-optical virtualprivate-network (VPN) schemes in passive optical networks (PONs). PON is a promising candidate in future access areas to provide broadband services with low cost. With all-optical virtual private network (VPN) function, PON can support efficient internetworking among end users with dedicated optical channels, thus enabling guaranteed bandwidth and enhanced security at the physical layer. Here, we discuss and compare existing schemes of all-optical VPNs in time-division-multiplexed (TDM) PONs, and also recently proposed schemes for deployment in wavelength-division-multiplexed (WDM) PONs and two-stage TDM/WDM PONs.
