Abstract: PURPOSE: An IP multicast servicing method using a virtual LAN is provided to introduce a VLAN(Virtual LAN) where a lower layer is supported on an IP multicast, and to supply an IP multicast service at a desired speed through a very high speed network, thereby reducing burden of a network equipment while transmitting packets without processing an upper layer. CONSTITUTION: A sender(41) generates a multicast group(501), and requests group management of an IP multicast/VLAN manager(42) through an IGMP(Internet Group Management Protocol)(502). The IP multicast/VLAN manager(42) admits or rejects the request(503). If the IP multicast/VLAN manager(42) admits the request(503-2), the sender(41) broadcasts a multicast session to hosts(504). The IP multicast/VLAN manager(42) stores a VLAN ID within a range of receiving an SDP(Session Description Protocol)(505). If a host wants to participate in the multicast group, the host applies for a participation to the IP multicast/VLAN manager(42)(506,507). The IP multicast/VLAN manager(42) forms a new VLAN with the stored VLAN ID(508), and transmits a participation message in IP multicast method(509).

Abstract: PURPOSE: A method for controlling a resource reservation using a two-pass RSVP(Resource Reservation Protocol) in an SBM(Subnet Bandwidth Manager) network is provided to efficiently maintain QoS(Quality of Service) by supporting a PEB(Pre-Engaged Bandwidth) on the basis of the two-pass RSVP in an IEEE802 style network. CONSTITUTION: A transmission host(50) transmits a path message together with a traffic specification for indicating the upper and lower limit of a bandwidth, a delay time, and a jitter to a reception host(10) through a certain segment(410). The reception host(10) transmits a PEBR(PEB Reservation) message to the transmission host(50) according to path state information of the traffic specification(420a-420d). The transmission host(50) transmits a PEBR acknowledgement message to the reception host(10)(430). The reception host(10) transmits a reservation message to the transmission host(50) for lastly reserving resources(440a-440d).

Abstract translation: 目的：提供一种用于在SBM（子网带宽管理器）网络中使用两遍RSVP（资源预留协议）来控制资源预留的方法，以通过支持PEB（预先约束的带宽）来有效地维持QoS（服务质量） 基于IEEE802风格网络中的双通RSVP。 组成：发送主机（50）通过某个段（410）向接收主机（10）发送路径消息以及用于指示带宽的上限和下限，延迟时间和抖动的业务规范。 接收主机（10）根据业务规范（420a-420d）的路径状态信息向发送主机（50）发送PEBR（PEB保留）消息。 发送主机（50）向接收主机（10）发送PEBR确认消息（430）。 接收主机（10）向发送主机（50）发送保留消息以最后保留资源（440a-440d）。
