摘要： A packet relay apparatus (100) identifies port information for identifying a port, included in a partition corresponding to a reception port having received a packet, from a partition information storing unit (111) which stores a correspondence between port information for identifying ports included in the partition and partition information for identifying the partition configured for the apparatus. The apparatus determines whether the identified port information is included in the port information stored by being corresponded to reception VLAN information which is VLAN information set for a received packet by a VLAN information storing unit (112) which is a storing unit storing a correspondence between port information for identifying a port used for transmission and/or reception of a packet transmitted and VLAN information for identifying the virtual network. The apparatus transmits the packet from a port determined to include the port information in response to the determination that the port information is included.
摘要翻译：分组中继装置（100）从分区信息存储单元（111）中识别用于识别包含在与已经接收到分组的接收端口相对应的分区中的端口的端口信息，该分区信息存储单元（111）存储用于识别用于识别为该装置配置的分区的分区和分区信息。该装置通过VLAN信息存储单元（112）来确定所标识的端口信息是否包含在与由接收VLAN信息设置的接收VLAN信息相对应的接收VLAN信息中，所述VLAN信息存储单元（112）是存储单元用于识别用于发送和/或接收发送的分组的端口的信息以及用于识别虚拟网络的VLAN信息。响应于包括端口信息的确定，装置从被确定为包括端口信息的端口发送分组。

摘要： A relay apparatus for use in a communications system having multiple VLANs. A packet storing unit (183) stores relay instructions for received packets in different queues depending on priority and a VLAN number. DRR schedulers take out relay instructions from respective queues through a DRR technique. A priority control transmission scheduler transmits the packets to another apparatus according to the relay instructions in a descending order of priority.
摘要翻译：一种用于具有多个VLAN的通信系统中的中继装置。分组存储单元（183）根据优先级和VLAN号码将接收的分组的中继指令存储在不同的队列中。 DRR调度器通过DRR技术从相应队列中取出中继指令。优先级控制传输调度器按照优先级顺序根据中继指令将分组发送到另一设备。

摘要： A packet relay program is executed for relaying a packet in a first sub-domain among a plurality of sub-domains in a service chain configured across the plurality of sub-domains. Furthermore, the packet relay program causes a computer to perform a process. The process includes specifying a transmission destination corresponding to identification information included in the packet and an index included in the packet on a basis of relay information with which identification information indicating a combination of a plurality of service functions included in the service chain, an index indicating an order for applying the service function, and the transmission destination are associated, changing the index included in the packet into a predetermined value when the specified transmission destination is a second sub-domain among the plurality of sub-domains, and transmitting the packet including the identification information included in the packet and the index of the predetermined value to the specified transmission destination.
摘要翻译：执行分组中继程序，用于中继在跨多个子域配置的服务链中的多个子域中的第一子域中的分组。此外，分组中继程序使计算机执行处理。该处理包括：基于指示包括在服务链中的多个服务功能的组合的识别信息的中继信息，指定与分组中包括的识别信息相对应的发送目的地和包括在分组中的索引; 用于应用服务功能的顺序和发送目的地相关联，当指定的发送目的地是多个子域当中的第二子域时，将包中包括的索引改变为预定值，并且发送包包括在分组中的标识信息和预定值的索引到指定的传输目的地。
