It researches the requirements of control plane in T-MPLS and analyses the architecture of control plane based on TMPLS
testbed. With the growth of the demand for packet transport services, packet transport network is becoming the
core technology for transport network, especially T-MPLS. Because of simply implement, independent control plane,
complete OAM, T-MPLS becomes the most promising technology for packet transport network. The control plane is
responsible for handling dynamically and in real-time network's esources in order to manage the establishment and
deletion of label switch path(LSP), and for disseminating and discovering network topology and resource availability
through the exchange of control (signaling and routing) messages between neighbor nodes over the data communication
network (DCN). It is composed of mainly four modules, connection controller (containing signaling module), routing,
resource manager, and protocol controller module. The four modules interact with each other to complete the control
plane's functions. The flow of every module is designed in this paper to complete control plane's software programming.

Although Gigabit T-MPLS technology has not been widely used for transmission network, it is attracting more and more
attention. The design of high-speed data switching is the key technology in T-MPLS. In this paper, one method that
implements 4 ports Gigabit T-MPLS switch chip on FPGA which is used for TDM over T-MPLS exchanging is
introduced, and the simulation and verification results will be given in the conclusions. It researches the requirements of
transport plane in T-MPLS and analyses the architecture, and demonstrates a design of TDM in Transport MPLS based
on FPGA through a testbed which is used to explore and implement the concepts of Transport MPLS.
Discusses the network architecture designed for providing carrier class metro Ethernet services over T-MPLS packet
transport network. Analyzes its characteristics and advantages from the aspects of data transport, OAM, end-to-end QoS,
protection mechanism and interworking.
It Researches key technologies and hardware node structure of the Transport MPLS packet network. Main technology is
super high speed FPGA. The transport plane adapts the layer 3 service signals from client equipments and forwards them.
There are two types of node in transport plane, edge node (EN) or core node (CN), and the nodes realized with large-scale
FPGA chip have three main function units and six types of board. The EN adapts the layer 3 service signals such as
TDM, Packet and Cell to TM signals by add shim. The CN is responsible for the TM signals switching in higher speed
than traditional packet network such as Ethernet. Control plane is embedded in a FPGA chip and designed based on the
ASON core technique (GMPLS) such as the transport label switching path (T-LSP) maintaining (set up, release, state
monitoring), route controlling and protect recovering and so on.
The key of analyzing the light signal transmitting in fiber is the interaction and correlation between them. At present, we
must consider the medium and the light field as one united system. Its strict physical theory is the quantum
electrodynamics (QED), to process the light field and medium to second quantization. The quantum theory is considering
both the medium and the light field as quantum wave function, so we can discuss the extreme limit frequency and
distance. In the analyzing of extreme limit frequency, we can get it by considering two situations: the first is the
photoelectric effect between light signal and fiber medium, the second is the transmission effect of high frequency
incident light. In the analyzing of extreme limit of light signal distance, we will consider the interaction of the electron
and the light field. We apply the theory and formula of scattering section. We analyze the colliding mechanism of
particles in medium. We calculate the transmitting situation of photon energy according the energy and momentum
reservation laws. According to the maximum frequency shift of light which is allowed by optical receiver, we can get the
extreme limit distance of signal transmitting.
