Abstract: Method and system for processing TCP segments is provided. The method includes assigning a TCP connection to a queue; and assigning a maximum burst size for the TCP connection; wherein a queue establishes a priority for the TCP connection and the priority is based on a maximum transmission rate assigned to the queue. The system includes a host system that establishes a network connection via a network adapter; wherein a host application sets a byte count and a time interval value for at least two queues that have different priority to transmit TCP segments; assigns a TCP connection to a queue; and assigns a maximum burst size for the TCP connection.

Abstract: A method and structure for the distribution and utilization of synchronization within an asynchronous network is described herein. Synchronization is distributed through an asynchronous network via a synchronization symbol periodically inserted on the MAC layer. The priority of this symbol ensures that this symbol is inserted in the MAC layer data stream ahead of all other types of symbols. The insertion of the synchronization symbol in the middle of an ongoing data frame is supported. In addition, a method for synchronization symbol distribution throughout an asynchronous network is presented, along with a method for switching to a new synchronization path (in the event of loss of original synchronization path) based on minimum number of hops from the synchronization source.

Abstract: An architecture for transport of multiple services in connectionless packet-based networks is described herein, along with the packet format used for data transport in this architecture. The architecture supports transport of both connectionless packetized data and framed data from synchronous leased lines. The architecture supports transparent packetization of incoming DS1 data. The architecture works for mesh architectures but is optimized for OSI Layer 1 (crossconnect) and Layer 2 (Virtual LAN, or VLAN) services and for ring topologies, since for these services in a ring no path setup is required using a label distribution protocol. In addition, it simultaneously supports OSI Layer 1, Layer 2, and Layer 3 services.
