Abstract
Embodiments of the present invention relates to an apparatus and method for routing AAL5 PDU in a mobile communication system, capable of routing AAL5 PDU using a Hash lookup table.
Claims37
A method comprising routing a packet of data according to a hashing function.
An apparatus configured to route a packet of data according to a hashing function.
An apparatus for routing an AAL5 PDU to an upper application program or a protocol layer via a plurality of service access points in a mobile communication system, comprising a router that contains a Hash lookup table using a remainder after dividing a channel code provided by a ATM chip by a size of the Hash lookup table as a Hash value, and when the router receives the AAL5 PDU from an ATM AAL5 layer via a single service access point, it retrieves channel information from the Hash lookup table by a channel code of the received AAL5 PDU and routes the received AAL5 PDU to the upper application program or the protocol layer.
A method for routing an AAL5 PDU in a mobile communication system comprising:
- constructing a Hash lookup table using a remainder after dividing a channel code provided by an ATM chip by a size of the Hash lookup table as a Hash value;
- executing a Hash function using the channel code of the AAL5 PDU as a key value as the AAL5 PDU is received, calculating a Hash value, and retrieving a channel having a channel code identical to the channel code from a bucket decided in the Hash lookup table by using the calculated Hash value;
- and
- deciding a routing type of the channel by checking a type of the retrieved channel, thereby routing the AAL5 PDU depending on the decided routing type.
