“…The live migration of VNFs is valuable for efficient resource use. We also proposed the Optical Layer 2 Switch Network (OL2SW-NW) [7] which is an expansion of dynamic bandwidth allocation [10] for multi-point to multi-point network. Moreover, we proposed virtual edge architecture that combines VNFs and OL2SW-NW for fixed network using the PON access network.…”

SUMMARY IoT (Internet of Things) services are emerging and the bandwidth requirements for rich media communication services are increasing exponentially. We propose a virtual edge architecture comprising computation resource management layers and path bandwidth management layers for easy addition and reallocation of new service node functions. These functions are performed by the Virtualized Network Function (VNF), which accommodates terminals covering a corresponding access node to realize fast VNF migration. To increase network size for IoT traffic, VNF migration is limited to the VNF that contains the active terminals, which leads to a 20 % reduction in the computation of VNF migration. Fast dynamic bandwidth allocation for dynamic bandwidth paths is realized by proposed Hierarchical Time Slot Allocation of Optical Layer 2 Switch Network, which attain the minimum calculation time of less than 1/100.

“…As a PON system, we assume 10 Gbit-Ethernet PON (10G-EPON) [7]. The proposed technique is applied to different types of TDM-based PONs such as wavelength division multiplexing (WDM)/TDM-PONs [8]. The processing delays in the OLT and ONU are not considered.…”

We propose a bandwidth allocation technique for accommodating a time division duplex mobile base station (TDD-BS) and a secondary system in a TDM-PON. Operating availability is confirmed with essential three types of TDD configuration taken from the seven types described by the Third Generation Partnership Project (3GPP) standardization group. We evaluate the latency of the TDD-BS and the throughput of the secondary system. We report that the TDD-BS signal is forwarded in less than about 50 µs and is unaffected by the secondary system. The throughput of the secondary system is improved compared with that of the conventional technique.

“…The Request message is also used to acknowledge the Confirmation message. Note that the upstream bandwidth needed to send the control messages is consistently assigned by the dynamic bandwidth allocation (DBA) [3] function of the OLT.

“…In particular, passive optical networks (PONs) can provide optical access services at low cost, and are widely deployed [3]. A PON is comprised of one optical line terminal (OLT) located at the central office (CO) and multiple optical network units (ONUs) located at user premises as shown in Fig.…”

SUMMARYThis paper proposes a power saving mechanism with variable sleep period to reduce the power consumed by optical network units (ONUs) in passive optical network (PON) systems. In the PON systems based on time division multiplexing (TDM), sleep and periodic wake-up (SPW) control is an effective ONU power saving technique. However, the effectiveness of SPW control is fully realized only if the sleep period changes in accordance with the traffic conditions. This paper proposes an SPW control mechanism with variable sleep period. The proposed mechanism sets the sleep period according to traffic conditions, which greatly improves the power saving effect. In addition, the protocols needed between an optical line terminal (OLT) and ONUs are described on the assumption that the proposed mechanism is applied to 10 Gigabit (10G) class PON systems, i.e. IEEE 802.3av 10G-EPON and FSAN/ITU-T 10G-PON systems. The validity of the proposed mechanism is confirmed by numerical simulations. key words: passive optical network, power saving, sleep control
