The packet forwarding behaviour of a network relies on the forwarding rules residing in the
networking element (eg switches and routers) to forward packets. This applies to both …

We study the problem of traffic grooming to reduce the number of transceivers in optical
networks. We show that this problem is equivalent to a certain traffic maximization problem …

We propose an IP forwarding table search engine architecture, VLMP (vertical logical
operation with mask-encoded prefix-length), for routers with multi-gigabit/sec speed links …

A quantum cryptographic key distribution (QKD) endpoint (405) includes a QKD receiver and
a feedback system (1600). The QKD receiver receives symbols transmitted over a QKD path …

(57) ABSTRACT A method for constructing routing/forwarding tables for an IP address
lookup using a skip list. The method comprises dividing a prefix length range of an IP …

A multigigabit IP router may receive several million packets per second from each input link.
For each packet, the router needs to find the longest matching prefix in the forwarding table …

It is becoming apparent that the next-generation IP route lookup architecture needs to
achieve speeds of 100 Gb/s and beyond while supporting IPv4 and IPv6 with fast real-time …

A content addressable memory (CAM) that includes a CAM array and a write circuit. The
write circuit is coupled the CAM array and has a coding circuit to convert a first value into a …

A content addressable memory (CAM) device including a CAM array and a priority index
table. The CAM array has a plurality of rows of CAM cells, each row including a plurality of …
