VLAN tunneling protocol

David Clear, +2 more
TLDR
In this article, a multiprotocol label switching (MPLS) protocol is used for identifying a next switching node in the label-switched path (LSP) to which the packet is to be transmitted.
Abstract: 
A virtual local area network (VLAN) tunneling system includes an ingress edge switching node that adds VLAN encapsulation information to a packet even if the egress port is configured to act as an untagged 802.1Q port. The packet is tunneled via a label-switched path (LSP) according to a multiprotocol label switching (MPLS) protocol. Label values are used for identifying a next switching node in the LSP to which the packet is to be transmitted. At a penultimate switching node in the LSP, a current label value is replaced with a label value reserved for packets originating from a port associated with a VLAN. An egress switching node in the LSP receives the packet with the reserved label value and recognizes that VLAN information is embedded in the packet. The egress switching node extracts the embedded VLAN information as well as the original source and destination addresses, and processes the packet for transmitting to a final destination.

Wireless load balancing across bands

Sudheer Poorna Chandra Matta
TL;DR: In this article, a technique for wireless load balancing involves providing a wireless infrastructure that creates a target band option and helps push clients toward that band, by responding only to probe requests on a first band when a client is detected on the first band and a second band.

Methods and apparatus for characterizing a route in a fibre channel fabric

Maurilio Cometto, +1 more
TL;DR: In this article, a technique for inserting time stamp information into frames transmitted from a source to a destination and back to the source is described. Time stamp information allows a supervisor associated with the source to determine characteristics such as round trip times, latency between hops, and connectivity to the destination for specific routes.
