Title:
ROUTE QUERY METHOD AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/176853
Kind Code:
A1
Abstract:
Disclosed is a route query method, comprising: receiving a packet via an input port and parsing the packet to acquire destination address information thereof; detecting whether or not address information and an entry matching the destination address information are present in an internal match table; if not, then detecting whether or not address information and an entry matching the destination address information are present in an external match table; if yes, forwarding the packet via an output port indicated by the matching entry; if a matching entry is absent in an external exact match table but present in an external universal match table, then detecting whether or not address information of the entry contains address information of the external exact match table; and if not, then saving the entry to an internal universal match table. Correspondingly, also disclosed is a network device. Employment of the present invention allows implementation of query acceleration simultaneously for an exact match table and a universal match table, allows conservation of internal storage space, and at the same time prevents the accidental deletion of an entry.
