Abstract: A method enabling symmetric routing between a first host within a first AS and a second host within a second AS is disclosed. The method includes detecting that a first routing message was received at an edge router of the first AS from an edge router of the second AS. The first message identifies the second host as a source and the first host as a destination of a forward route. The method further includes determining that the first message further comprises an indication to implement symmetric routing between the first and second hosts and generating a second routing message for propagating to router(s) within the first AS. The second message identifies the first host as a source and the second host as a destination of a return route, and indicates that data is to be sent via the edge router of the first AS that received the first message.

Abstract: An apparatus includes a first wireless bridge device configured to transmit signals to and receive signals from wireless network access points located along a pathway, and a second wireless bridge device configured to transmit signals to and receive signals from the wireless network access points. The first wireless bridge device and the second wireless bridge device are coupled to and communicate with each other. When the first wireless bridge device is wirelessly connected to a first access point and about to initiate a roaming mode to attempt to wirelessly connect to a second access point, the first wireless bridge device notifies the second wireless bridge device of the initiating of the roaming mode and determines whether the second wireless bridge device is in the roaming mode while the apparatus is moving along the pathway.

Abstract translation: 公开了一种能够在第一AS内的第一主机与第二AS内的第二主机之间进行对等路由的方法。 该方法包括检测从第二AS的边缘路由器在第一AS的边缘路由器处接收到第一路由消息。 第一个消息将第二个主机标识为源，将第一个主机标识为转发路由的目的地。 该方法还包括确定第一消息还包括在第一和第二主机之间实现对称路由的指示，并且生成用于传播到第一AS内的路由器的第二路由消息。 第二消息将第一主机标识为源，将第二主机标识为返回路由的目的地，并指示将通过接收到第一消息的第一AS的边缘路由器发送数据。
