Abstract: In a system in which several data links are available for the transmission while one respective sending unit is allocated to the data links to temporarily store data that is to be transmitted via the respective data link, data packets containing non-real-time critical data are subdivided into fragments of variable sizes prior to forwarding to a sending unit. Data packets containing real time-critical data are preferably forwarded to a sending unit without being fragmented. Additionally, a minimum fragment size can be predefined for the fragmentation process.

Abstract: Disclosed is a method for managing a group of network access servers (ZSI, ZS2, . . . ZSN) wherein the Multichassis Multilink Point to Point Protocol (MMP) is used. An address list of the other network servers of a group (ZS1, ZS2, ZSN) is managed for each network access server of said group (ZS1, ZS2, . . . , ZSN). According to the invention, the logging on and/or off of a new network access server (ZSN+1) to or from said group occurs in such a way that an address list of a network access server (ZS) always includes the current state of the network servers (ZS1, ZS2, . . . , ZSN) in the group. The invention also relates to a network access server (ZS) used to carry out the inventive method.
