Abstract: In an NXN packet switch, for example an ATM switch, multicast connections receive backpressure signals from congested output ports in the switch core. The cells in the connections are destination address modified not to send to the congested output port, but to continue sending to the other output ports in the connection. The multicast cells may include a user selected primary route identification and be queued in a unicast input queue for the primary route before being destination address modified. Destination address modification for congestion may be accompanied by partial packet discard, through destination address modification of the remaining cells forming part of a multiple cell packet to remove the destination address for the congested port (whether or not it is now congested) where one of the multiple destination addresses of one of the cells in the packet has been modified to remove the destination address of the congested output port. Destination address modification for congestion, without or without partial packet discard, may be accompanied by hybrid head of line blocking performed by not sending from a multicast queue if an output port on one of the multicast leafs is congested and the input queue size is below a given threshold, and sending with destination address modification and optional partial packet discard if the queue size is above the threshold.

Title: Method of accessing an ip in an isdn network with partial release
Inventor: GOYAL DEVKI N
IPC: H04Q11/04
Filed: 1998-07-16
Granted: 2005-12-20
Abstract: A method and system in an ISDN network for exchanging call control information between a switch and an IP, and for call set-up and call clearing for intermediate access to an IP. The invention utilizes the User-User Information (UUI) element of the Q.931 messages to exchange call information between a switch and an IP. A subscriber call results in a connection being established to an IP. A request to the IP is encoded in the UUI element of a SETUP message, and call routing information is encoded in the UUI element of a returned DISCONNECT message. The DISCONNECT message causes a partial call release of only the circuit segments from the IP back to the switch. The circuit segments from the calling party to the switch are maintained. The switch then routes the user call to a final destination based on information contained in the UUI element of the DISCONNECT message.

Abstract: A cable closure (10) assembly using a cold shrink, or pre-stretched, tube (1 2) has a flowable material (16) in the assembly (10), and an extra support core (18) which reinforces the conventional support core (1 4) that maintains the tube (12) in a radially expanded state. The flowable material (16) may be used to fill voids, or provide improved bonding or water resistance. The extra, or secondary, support (18) core has an outer diameter which is approximately equal to inner diamet er of the primary support core (14). The secondary support core (18) is sufficiently long to substantially support the area where the flowable material (16) abuts the primary support core (14). In one embodiment particularly suited for power applications, the elastomeric tube (12) is electrically insulative and the flowable material (16) provides electrical stress control, and another elastomeric tube (20) is provided having a high permittivity. The primary support core (14) may have a varying diameter such that the tubular member (12) has different zones with different expanded diameters. The secondary support core (18) is preferably removed just prior to product application (leaving the larger core intact) so as to increase the product's shelf life.
