摘要： In a network having an L2SW in which uplink VLAN is set, a transfer delay of a voice call packet is prevented. In a process of establishing a session between terminals (5), a packet transfer device (1) stores information capable of specifying a sending terminal (5-1) and a receiving terminal (5-2) and a correspondence relation (user connection information) to a connection port into a table. A SIP message of a session control packet communicated between the terminals (5) is snooped, and a destination IP address, a transmission source IP address, a destination port number, a transmission source port number, a connection port etc. are stored into the table. In a case where an RTP packet as voice data is received after the session is established, the packet transfer device (1) performs a loopback transfer or transfers it to an uplink port in accordance with the table.

摘要： Disclosed here is a communication apparatus and method for inter-AS routing, which enables policy routing between a stub AS and an upstream AS. The policy routing includes control which is applicable only between adjacent autonomous systems (AS's). When a subject communication apparatus notifies its own AS number or advertises attribute information that includes its own AS number to a stub AS, the communication apparatus does not use its own AS number or uses the AS number of the upstream autonomous system (AS) instead of its own AS number. In addition, when relaying routing information received from one AS to another, the subject communication apparatus also relays attribute information without discarding the information, although the information is conventionally not relayed to itself.
摘要翻译：这里公开了用于跨AS路由的通信装置和方法，其使得能够在存根AS和上游AS之间进行策略路由。策略路由包括仅适用于相邻自治系统（AS）之间的控制。当主题通信装置通知其自己的AS号码或向存根AS发布包括其自己的AS号的属性信息时，通信装置不使用其自己的AS号码或使用上游自治系统（AS）的AS号码而不是自己的AS号码。此外，当将从一个AS接收到的路由信息中继到另一个时，主体通信装置也中继属性信息而不丢弃该信息，尽管该信息通常不被中继到其自身。
