  • Page 119: Ethernet Features Description

    6.3 - Ethernet Features Description Two basic built-in applications are available : bridging and bandwidth allocation. The Ethernet interface allows to connect SAGEM LINK F to standard IEE 802.3 Ethernet devices. 6.3.1 - Ethernet Bridging When bridging is selected, the system learns automatically the MAC addresses of subscribers and forwards only those packets destined for the service side.

  • Page 120: Bandwidth Allocation

    6.3.2.1 - Learning process : The SAGEM-LINK F is able to allocate bandwidth fairly by routing outgoing traffic through a set of queues and scheduling the release of frames, from each queue, in an equal and fair manner. To do this the Bandwidth Allocator (BA) must know which network devices on the Subscriber Network are communicating with the Service Network and it must assign queues to those network devices.

  • Page 121: Ethernet Interface Configurations

    The Queue Recovery mechanism works as follows: 1. When a Private Queue is available the SAGEM LINK F polls the MAC Table every 6 seconds to find the device or VLAN with the most Service Network traffic that does not have a Queue assigned to it.

    When the green LED is lit, it indicates that the Ethernet cable is properly connected to an Ethernet device. When it flashes it indicates Ethernet activity.
