The invention relates to report process method of optic network terminal, report processing includes following steps: B1. ONT receives up-bound message from user network interface which is distributed with VLAN operation distribution data property; B2. the user network interface function module of ONT operates the said VLAN Tag based on VLAN operation distribution data property, said operation of VLAN Tag are divided into three types, one is operation of VLAN marking VID and VLAN PRI, two is operation to inner layer, three is operation to outer layer, the ONT executes any type of said operation or combination of said three types. The method of the invention simplifies the operation of VLAN Tag, and the operation mode of VLAN Tag can be expanded flexibly, and it is convenient to realize various operation modes of VLAN Tag.

A method and system for location-aware wireless mobile devices including a mobile user network interfaces and protocol. A network-independent location-aware network protocol provides communication with location-aware wireless mobile devices. The protocol is network-independent to support and deliver location-aware services over virtually any wireless or wired network transparently regardless of the protocols being used on a transport network. The protocol is location-aware of current geographic locations of plural wireless mobile devices. Alert information is provided to a location-aware wireless mobile device with the network-independent location-aware network protocol and interfaces. Location-aware wireless mobile devices are located and provided with alert information with the network-independent location-aware network protocol and interfaces. The method, system, interfaces and protocol may help improve usability of mobile devices by allowing the mobile devices to be location-aware.

Bandwidth distributed according to need traffic (BDANT) is corresponding to a virtual cascade connection set. The method includes steps: through control plane signaling, user network interface client end UNI-C sends bandwidth adjustment message based on BDANT to user network interface network end UNI-N; the bandwidth adjustment message includes adjustment quantity of bandwidth; based on the adjustment quantity of bandwidth and bottom tunnel granularity, UNI-N adjusts bandwidth. Instance in the invention also discloses bandwidth adjustment device in BDANT. Combining control plane GMPLS technique with LCAS, VC and GFP technique in transmission plane, the invention establishes BoD traffic automatically, and client end can carry out traffic bandwidth adjustment in real time dynamically based on change of flow of traffic.

A technique efficiently manages bandwidth (BW) for multipoint-to-multipoint (MP2MP) services in a provider network of a computer network. According to the novel technique, each bridge having a user-network interface (UNI) port of an MP2MP service generates a registration for the service that carries maximum BW values for each port direction (e.g., for each {service, priority, color} triple), e.g., as defined by a Service Level Agreement (SLA). The registrations are advertised among neighboring bridges throughout the network toward other UNI ports of the MP2MP service. As each bridge receives registrations from each neighboring bridge (or from the UNI port), the bridge advertises registered BW values pertaining to a particular direction on a particular one of its ports that correspond to the sum of the BW values for that direction received on all of the other ports of the bridge, up to a maximum BW value (e.g., configured or physical) for the particular port. The actual BW required for allocation on an active port for each direction is the lower of either the registered value advertised from the port in a particular direction or the registered value received at the port in the opposite direction.

Systems and methods for fault tolerant communication are provided. A base site is coupled to a central office via a channel service unit. The channel service unit is coupled to the central office via primary and secondary communications links. A first and second permanent virtual circuit couple the channel service unit to a wireless carrier core network. When there is a fault on the primary communication link or the primary permanent virtual circuit user network interface of an aggregator, the secondary communication link is established and the secondary permanent virtual circuit is activated. Communications are then routed to the wireless carrier core network via the secondary communication link and the secondary permanent virtual circuit.

A data compute node executes (i) a set of tenant applications connected to a third party overlay network, (ii) a set of network manager applications, and (iii) a managed forwarding element that includes a pair of overlay and underlay network virtual adapters. A packet that is received from a network manager application and addressed to an underlay network destination is sent to the underlay network destination address through a physical NIC of the host without network address translation or encapsulation. A packet that is received from a tenant application and addressed to an underlay network destination is subject to SNAT and is sent to the underlay network destination address. A packet that is received from a tenant application and is addressed an overlay destination address is encapsulated with the header of the overlay network and is sent to the overlay network destination address through the underlay virtual adapter.
