摘要:
A method for monitoring traffic in a packet switched network. The packet switched network includes connections grouped in a single group; token buffers for respectively corresponding to the connections, and storing tokens generated at a predetermined token generation rate by the corresponding connection; a shared token pool for being shared among the connections, and storing the generated tokens therein when each token buffer of each connection is over a predetermined maximum size; and counters for respectively corresponding to the connections, and counting tokens stored in the shared token pool by a corresponding connection. The method for monitoring traffic in the packet switched network includes the steps of: a) providing data buffers for respectively corresponding to the connections and storing a packet of a contract-following connection in case of a temporary deficiency of a network resource; b) if a token buffer of a corresponding connection is over a predetermined maximum size and the shared token pool is over its own predetermined maximum size, storing tokens generated during a token generation time in the shared token pool, and controlling a count value of a corresponding counter; c) checking the count value of the corresponding counter, and selectively controlling a permitted buffer size of a data buffer of a corresponding connection upon receiving the checking result of the count value of the corresponding counter; and d) checking a token buffer of a corresponding connection and a shared token pool if a packet reaches the corresponding connection or is present in a data buffer of the corresponding connection, and selectively storing a received packet in a corresponding data buffer according to a count value of a corresponding counter if there is no token in the token buffer of the corresponding connection and the shared token pool.

Provided is a method and apparatus for reserving a session resource in an IPv4/IPv6 combination network system. It allows a node to simultaneously establish an end-to-end session and a tunnel session by notifying a starting node of the tunnel session in advance about whether a last node supports RSVP while assigning IPv4 address information to an IPv6 host according to DSTM upon reserving a resource according to an RSVP mechanism in a 4over6 dual stack transition mechanism (DSTM) environment.

In a method and system for supporting resource reservation protocol (RSVP) in an Internet protocol version 4 (IPv4)/Internet protocol version 6 (IPv6) hybrid network, the method includes the steps of: transmitting, from a dual stack host in an IPv6 network, an end-to-end quality of service (QoS) session establishment request message to an IPv4 server through a dual stack transition mechanism tunnel end point (DSTM TEP); transmitting, from the IPv4 server, an end-to-end path message to the dual stack host through the DSTM TEP; transmitting, from the DSTM TEP to the dual stack host, a path message for reserving resources in the IPv6 network; transmitting, from the dual stack host, an end-to-end resource reservation request message to the IPv4 server through the DSTM TEP, and making a resource reservation in an IPv4 network; and transmitting, from the dual stack host to the DSTM TEP, a resource reservation request message, and making a resource reservation in the IPv6 network.

A traffic exchanging method for a mobile node in a mobile network reduces packet loss during hand-over latency, and defines new messages in order to prevent packet disorder. By defining a message indicating that earlier received packets have all been delivered, it is possible to prevent packet disorder. This has an effect of reducing packet loss and preventing packet disordering while a mobile host exchanges traffic in a mobile network. This solves the performance degradation of application layer protocol caused by packet disordering.

In a method and apparatus for processing a packet in an IPv4/IPv6 combination network, packet overhead is minimized by identifying a tunnel session through a flow label field of an IPv6 header in a tunnel section when the packet is forwarded in a tunneling manner depending on a resource reservation protocol (RSVP) in the IPv4/IPv6 combination network.
