Abstract: Methods, non-transitory computer readable media, rendezvous gateway (RG) apparatuses, and network security systems that send an RG synchronization message (SYN) to an application in a secure domain following receipt, from a client, of a client SYN comprising an indication of the application. A rendezvous agent (RA) SYN is received, via a firewall coupled to the security domain and in response to the RG SYN, from an RA in the secure domain. A first RG synchronization-acknowledgement message (SYN+ACK) is sent to the client in response to the client SYN. A second RG SYN+ACK is sent, via the firewall, to the RA in response to the RA SYN. The RA is notified of receipt of a client acknowledgement message (ACK) from the client. An RA ACK is received, from the RA and via the firewall, in response to the notification, to thereby establish a full connection between the client and the application.

Abstract: Upon detecting a data event initiating an update to a table, a first classifier index associated with the data event is identified. From a classifier table, the current position in a first dimension of the table associated with the classifier index is determined. An open position in the first dimension of the table is also identified. Updated data is stored in the open position within the table. In the classifier table, the open position storing the updated data is associated with the classifier index.

Abstract: A shared memory packet switch fabric whose scheduling task is distributed to multiple egress schedulers residing on multiple egress control units and whose data storage is distributed to multiple packet buffer units, where the schedulers and the packet buffer units are interconnected via high speed links. An ingress control unit receives and transmits a packet to one of a plurality of packet buffer units (PBUs) making up the switch fabric. The receiving PBU stores the packet in memory and transmits a notification message with the memory information to all interested egress control units. If an egress control unit receiving the notification has enough queue space, it stores the memory information in its queue. The egress control unit then transmits a booking message indicating that it is to request the packet in the future.

Abstract: A data communications network having a primary router, a secondary router and a peer router is disclosed. In operation the primary and peer router conduct a peer session to exchange information regarding the current state of the network topology. In addition, the secondary router monitors the peer session to maintain awareness of the current state of the network topology and replaces the primary router upon detecting a failure of the primary router.
