A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the fracture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs. Using the DTTL method a deeper wellbore can be drilled with larger resulting end tubulars, such as casings and production liners, than had been capable with conventional MPD applications.

A Wireless LAN Context Control Protocol (WLCCP) is used to establish and manage a wireless network topology and securely manages the “operational context” for mobile stations in a campus network. The WLCCP registration protocol can automatically create and delete links in the network, securely distribute operational context, and reliably establish Layer 2 forwarding paths on wireless links. A single infrastructure node is established as the central control point for each subnet, and enables APs and MNs to select the parent node that provides the “least-cost path” to a backbone LAN. Context messages provide a general-purpose transport for context and management information. WLCCP “Trace” messages facilitate network diagnostic tools. Ethernet or UDP/IP encapsulation can be used for WLCCP messages. Ethernet encapsulation is employed for intra-subnet (e.g. AP-to-AP or AP-to-SCM) WLCCP messages. IP encapsulation is used for inter-subnet WLCCP messages and may also be used for intra-subnet WLCCP messages.
