Title:
パケットフォワーディング方法、システム、および装置
Document Type and Number:
Japanese Patent JP6448660
Kind Code:
B2
Abstract:
Embodiments of the present invention are applied in the field of communication technologies. Disclosed are a packet forwarding method, system, and apparatus. A communication device computes a remainder for a determined total number of links by using a hash value of a data packet, the total number of links being 2 raised to an integer power and capable of comprising a sum of the added number of virtual links and the number of actual links for forwarding data packets; if a remainder value of the total number of links computed by using the hash value corresponds to a virtual link, computes another hash value of the data packet and executes a remainder computing step based on the another hash value; operates cyclically until the remainder value of the total number of links computed by using a hash value corresponding to the data packet corresponds to an actual link, and forwards the data packet on the actual link; if the remainder value of the total number of links computed by using a hash value corresponds to a virtual link, directly computes a remainder of the total number of actual links by using the hash value of the data packet, and forwards the data packet on the actual link corresponding to the remainder value. Data packets are allocated to actual links as evenly as possible, thereby reducing an impact on a service.
