A New Regional Code Label Switching and Network Performance Analysis
A new label switching scheme based on regional code is proposed.The framework
operational principle and main characteristics of the system are described.The scheme divides the whole Internet into regions
and every region is assigned a unique fixed length regional code.The corresponding regional code label is inserted between data link frame header and IP packet header by accessing label switching when packet accesses label switching network.The core label switching identifies destination regional code of packet to follow the packet in label switching network only.It is showed by theoretical analysis and simulation that the network can greatly reduce the number of routing entries in routers
and largely lessen link bandwidth and processor overhead for maintaining these entries.The scheme can effectively overcome the Internet shortcoming of IPv4 address space exhausted
simplify the complexity of the implementation of the core switching
