Abstract
The present invention presents Link Encapsulation Protocol (LEP) used to Multiple Services Ring (MSR) based on FE/GE/10GE aggregates in the way of pre-plan and connection based. LEP is provided for specific use on a N-ring structure (N=1, 2, 3, 4, 5, . . . ,) consisting of the unidirectional (N−M) ringlets and M (I≦M
Claims22
A data transmission apparatus used in a multiple service ring including at least two nodes coupled to at least one aggregate pipe and at least one tributary, said apparatus comprising:
- a tributary RX framer coupled to a tributary for deframing data frames received from said tributary and extracting a destination node address;
- a TX framer for encapsulating the destination node address and the data received from the tributary into frames of the multiple service ring and transmitting the same along an aggregate pipe to a downstream neighbor node in the ring;
- a RX framer for receiving and deframing data frames of the multiple service ring from a upstream neighbor node along an aggregate pipe to obtain at least a destination node address and actual data;
- a filter for determining data frames for local node according to the destination node address, and forwarding the other frames to said TX framer so as to forward the other frames to a next node;
- a tributary TX framer for encapsulating said data frames for local node into tributary data frames and sending the tributary data frames to a corresponding tributary.
A data transmission method used in a multiple service ring including at least two nodes coupled to at least one aggregate pipe and at least one tributary, said method comprising the steps of:
- for data frames from a tributary,
- receiving and deframing data frames from said tributary and extracting a destination node address;
- and
- encapsulating the destination node address and the data received from the tributary into frames of the multiple service ring and transmitting the same along an aggregate pipe to a downstream neighbor node in the ring;
- and for data frames from a upstream neighbor node along an aggregate pipe,
- receiving and deframing data frames of the multiple service ring from the upstream neighbor node along the aggregate pipe to obtain at least a destination node address and actual data;
- determining data frames for local node according to the destination node address, and forwarding the other frames to a next node;
- and
- encapsulating said data frames for local node into tributary data frames and sending the tributary data frames to a corresponding tributary.
