Abstract
A route selecting method includes performing a route search for obtaining route information from destination information contained in a received packet; attaching the route information obtained by the route search to the received packet; storing the packet having the route information in a buffer; reading the packet stored in the buffer sequentially from the route information attached to the packet; selecting an output route for the packet read from the buffer based on the route information read from the buffer; and outputting the packet via the selected output route.
Claims6
A route selecting method comprising:
- performing a route search for obtaining route information from destination information contained in a received packet;
- attaching the route information obtained by the route search to the received packet;
- storing the packet having the route information in a first buffer;
- reading the packet stored in the first buffer sequentially from the route information attached to the packet;
- selecting a first output route based on the route information read from the first buffer;
- and
- outputting the packet read from the first buffer via the first output route.
A router apparatus comprising:
- a route search unit configured to obtain route information from destination information contained in a received packet;
- a first buffer unit configured to store the received packet while the route information obtained by the route search unit is attached to the packet;
- a first read unit configured to read the packet stored in the first buffer unit sequentially from the route information attached to the packet;
- and
- a first switch unit configured to select a first output route based on the route information read by the first read unit from the first buffer unit, and configured to output the packet read by the first read unit from the first buffer unit via the first output route.
