    摘要： A communications system comprises a memory which is shared by a plurality of users, each one receiving and transmitting messages to each other. In the present system, a message is composed of a plurality of data buffers stored in the memory and each data buffer is controlled and mapped to a unique direct control block (DCB) which stores the characteristics of said data buffer. The chaining of the DCB forms the whole message which may be multicast to a plurality of users. Therefore, in order to improve the performance of such communications system, one may duplicate the message as many times as necessary without re-writing the data in the personal storage of each user by using an indirect control block (ICB) which represents the message duplicated. Each ICB stores the characteristics of the message duplicated and points to a DCB. A field in the DCB enables to count the number of duplication of the message. The DCB and ICB stores different fields which are required in order to perform the operations of lease control block from the free queues, the operations of message enqueue in the user queue, the operations of message dequeue from the user queue, and the operations of message release to the free queues. Two separate free queues FDCBQ and FICBQ chaining the free DCB and ICB are provided and are controlled by two control blocks FDQCB and FIQCB.
    The present apparatus and method may also be used for multicasting data buffer which composes a message by adding new fields in the ICB. In this case, the message to be multicast may have a content different from the original one, which requires therefore that to each ICB correspond a unique DCB.

    摘要： In a networking environment including one or more network processing (NP) devices and implementing a routing protocol for routing data packets from a source NP devices to destination NP devices via a switch fabric, with each network processing device supporting a number of interface ports, a system and method for enabling a routing system to recover more quickly that the routing protocol so as to significantly reduce the occurrence of lost data packets to a failed target interface/blade. The routing system is enabled to track the operational status of each network processor device and operational status of destination ports supported by each network processor device in the system, and maintains the operational status as a data structure at each network processing device. Prior to routing packets, an expedient logical determination is made as to the operational status of a target network processing device and target interface port of a current packet to be routed as represented in the data structure maintained at the source NP device. If the target blade/interface is not operations, an alternative route may be provided by ECMP. In this manner, correct routing of packets is ensured with reduced occurrence of lost data packets due to failed target NP devices/ports.

    摘要： A hub featuring several ports for attachment of stations to a LAN comprises concentration logic (14) for the handling of multiplexed incoming and outgoing Token-Ring and isochronous flows from and to the stations.
    The concentration logic comprises a clock recovery logic (42) from incoming Token-Ring packet data stream (40), for regeneration of Differential Manchester encoded data on output (400), and recovering of Token-Ring clock (401).
    A cycle framing generator (43) receives a 125 us synchronization clock (local or remote) from the hub backplane (402), and the Token-Ring clock (401), and generates control signals (403) to each of the 10 ports.
    Each port is made up of a port transmit interface (44), and a port receive interface (45).
    Data from a station hooked to the hub is input (404) to port receive interface (45). Token-Ring packet Differential Manchester encoded data are output (406) on to the next active port, and specifically to its port transmit interface, along with a recovered strobe clock (405), while ISO data are output (407) to a switch (46).
    The switch receives a hub local clock (412), which otherwise distributes on the whole concentration logic. isochronous traffic interchange with the hub backplane is ensured thru leads 410 and 411; inbetween ports or between ports and the hub is ensured thru leads 407 and 409 replicated for each port.
    Data to the station hooked to the hub is output (408) from port transmit interface (44). Differential Manchester encoded data are received (400) along with Token-Ring clock (401). Control signals are input (403). Isochronous data are received (409).
    Token-Ring packet Differential Manchester encoded data are finally output from the concentration logic (41).

    摘要： Packet switching node in a communication system includes apparatus for receiving incoming information packets or frames which contain header portions with formatting control blocks. Information in the frame's header contains frame alteration commands for modifying the information in the frame. The modifications include adding new information, deleting information, and overlaying information. Decoders and control devices in an alteration engine interpret the commands and apply the modifications to the frame data. Common and standard data patterns are stored for insertion or overlaying to conserve data packet space.

    摘要： A method, system and computer program product for translating a type of service field of one protocol into multiple protocols. An ingress router in a DIFFerentiated SERVices network (Diffserv over MPLS network) may determine a type of quality of service, e.g., forward IP packet using best effort. A value referred to as a Per Hope Behavior (PHB) value may be generated based on the identified type of quality of service. The PHB value may be used to index into a table comprising a row of entries with different quality of service values, e.g., DSCP value, EXP value, corresponding to a particular PHB value. Consequently, the PHB value may be used to perform a single memory access to determine the quality of service values for a plurality of protocols where the quality of service values corresponds to the identified type of quality of service.

    摘要： Method of upgrading a program, used in a data processing device having a permanent memory, from a version n to a version n+1 wherein, at any time, both recent version and previous version of the program are stored in a first (10) and a second (14) locations of said memory. Each one of version n and version n+1 of the program is using respectively configuration data of format n and format n+1 when it is used as current version. The configuration data of format n are automatically stored into said memory when version n+1 of said program is stored into said second location of memory.
