Abstract: A method and apparatus for determining reservation information are provided. The method includes: acquiring service time data of each service set by a service provider, wherein the service time data comprises a service period corresponding to each service; according to the service period of each service, determining the duration unit of the service provided by the service provider; dividing, according to the duration unit, the service time data into at least one service time unit, and storing data of each service time unit in a storage unit; and in response to receiving a service request for a first service sent by a service requester, setting, within the service period of the first service, the storage unit corresponding to each service time unit to be a read-only storage unit.

Abstract: A method for transmitting packets in an RPR includes: pre-setting an MAC table having an item which is a corresponding relationship between the node MAC address and the UE MAC address of each node; an RPR node receiving an insert packet, performing the MAC table lookup, deciding whether an item matching a destination MAC address of the insert packet exists; if there exists the item, converting the insert packet to an extended frame-formatted packet where the RPR destination node MAC address equals to the node MAC address of the item and sending the converted packet to the destination node, and performing the corresponding process; if there does not exist the item, converting the insert packet to an extended frame-formatted packet where the RPR destination node MAC address equals to a broadcast MAC address, broadcasting the converted packet on the whole network, and performing the corresponding process.
