The method and apparatus for transmitting data

Technical field

The present invention relates to the communications field, the method and apparatus of the transmission data more particularly in the communications field.

Background technology

Multiprotocol label switching (Multi-Protocol Label Switching, referred to as " MPLS ") technology It is Internet of lower generation broadband network technology, the route of data and forwarding are separated by MPLS technology, profit Explicit path is established with CR- LDP, and then establishes label switched path (Label Switched Path, letter Claim " LSP "), Segment routing (Segment Routing, referred to as " SR ") is a kind of MPLS technology, SR mainly includes node label and link tags, and node label is that each node calculates arrival target section The shortest path information of point, and present node and next hop information are issued in forward table, Mei Gejie Point preserves all node labels in respective forward table, final according to shortest path information and node label Destination node can be reached, node label uses shortest-path first algorithm, but due to network can not be balanced Load, it is overweight to can frequently result in some link loads in network, and other link circuit resources are without fully profit With so that can meet that congestion occurs for the network of traffic demand originally.In order to avoid congestion occurs for network, Introduce link tags, link tags are label of each node for local all links distribution, Mei Gejie The forward table of point only preserves the link tags of this node, and each node by link tags according to in-house network Agreement (interior Gateway Protocols, referred to as " IGP ") broadcasting link label is closed, in order to source Node can obtain the link tags of each node, and source node is after the link tags of each node are obtained One forward-path is determined according to the flow information message of each node, and increased in the heading of message Link tags indicate forwarding of the network node to message, after node receives message, according to the chain of top layer Road sign label find an exit, and are that local label is peeled off by the link tags of top layer, until purpose network section During point, all link tags in heading can be all stripped off.Internet protocol sixth version (Internet Protocol Version 6, referred to as " IPv6 ") network is also to transmit number by way of like link label According to.But due to Internet protocol fourth edition (Internet Protocol Version 4, referred to as " IPv4 ") During transmitted data on network, address source address and destination address that the headings of data includes, Wu Fatong The mode of the address for peeling every layer off is crossed to transmit data, data are transmitted in IPv4 networks with certain Limitation.

The content of the invention

The method and apparatus of transmission data provided in an embodiment of the present invention, can improve being applicable for data transfer Scope.

First aspect, there is provided a kind of method of processing data, this method include：First network node connects Receiving text, the heading of the message carry configured information, and the configured information is used to indicate N number of node serial number In Target Link numbering corresponding to each node serial number, N number of node serial number corresponds to the forwarding of the message N number of network node on path, N are the integer more than or equal to 2；The first network node determines should The node serial number of first network node；The first network node according to the heading of the message, it is determined that with this First object link number corresponding to the node serial number of first network node；The first network node this Corresponding to one Target Link numbering the message is forwarded on link.

So, N number of node serial number can correspond with N number of network node on the forward-path of message, N number of node serial number corresponds with N number of Target Link numbering, after first network node receives the message, First network node determines the node serial number of itself, and determine and own node numbering pair according to heading The first object link number answered, in such manner, it is possible to determine to E-Packet according to the node serial number of network node Target Link numbering, the scope of application of data transfer can be improved, such as can be in IPv4 networks Transmission.

Specifically, N number of network node includes source network node and target network node, N number of network section For each network node in point when receiving message, heading includes configured information, and the configured information can For indicating the node serial number of network node and the corresponding relation of Target Link numbering, can also indicate that every Individual Target Link numbering takes the position of heading byte, and each network node can be according in heading Configured information come determine itself numbering corresponding to Target Link numbering, and according to the configured information indicate it is every The node serial number of individual network node takes heading byte location to search the object chain of each network node Road is numbered, the instruction in link corresponding to the Target Link numbering found, heading Information all exists in the repeating process of whole message, avoids passing through stripping per layer address to transmit data, Even if the only source address and destination address of message, can also be avoided by configured information come transmitting message Limitation of the message in network transmission, improves the scope of application of data transfer, such as goes for The data transfer of IPv4 networks.

Alternatively, the configured information can indicate that the Target Link numbering of each network node takes heading The byte of identical quantity, and the Target Link of N number of network node numbers the arranged in sequence in heading； Alternatively, each network node can in order be searched according to the node serial number of itself and numbered with own node Corresponding Target Link numbering.

Alternatively, the configured information can indicate that Target Link numbering can account for corresponding to each network node With the byte of heading varying number, alternatively, each network node is according to itself node serial number and refers to Show information searching Target Link numbering corresponding with own node numbering.

Alternatively, for the heading of the message in addition to carrying configured information, heading also carries N number of section Point numbering, so, after each network node receives message, really the node serial number of itself, and passing through Search own node in message to number, after finding own node numbering, search and own node numbering pair The Target Link numbering answered, E-Packeted corresponding to Target Link numbering on link, so, heading In Target Link numbering can not store in sequence, can be by searching node serial number and Target Link The corresponding relation of numbering come determine Target Link number.

Wherein, the node serial number is used to identify network node, for example, the node serial number can be used for identifying Network node is which jump on forward-path, and the node serial number can also be the life of message in network node Deposit result of time and max-forwards node number complementation, etc..The node serial number can also be according to it He determines mode, is not restricted here.The node serial number of same network node may be different in transmission Message is different.Network node can determine the Target Link to E-Packet according to the node serial number of itself Numbering, further it is determined that Target Link numbering corresponding to E-Packet on link.

Alternatively, the first network node can determine the node serial number of itself according to the message, such as First network node can determine the node serial number of itself according to the life span of the heading of the message； In another example first network node can be according to the current transmission hop count of the message in the heading, it is determined that certainly The node serial number of body.

In the first possible implementation of first aspect, the first network node receive message it Before, this method also includes：The first network node sends the first network node at least to the first equipment One link number, wherein, at least one link number includes the first object link number, and First object link number byte-sized shared in the heading is according at least one link Maximum link number determines in numbering.

Alternatively, first object link number byte-sized shared in the heading can be for this at least Byte-sized in one link number shared by maximum link number.

So, demand size of the first object link number in the byte-sized shared by heading according to reality It is determined that and each link tags of the prior art take fixed 32bit, all links on path Label is all encapsulated in heading, causes link tags to take substantial amounts of message space, and efficiency of transmission is low, Byte of the embodiment of the present invention according to shared by the demand size of real bytes determines first object link number Size, in such manner, it is possible to reduce the space for taking message, further improve the efficiency of transmission data.

With reference to the above-mentioned possible implementation of first aspect, in second of possible realization of first aspect In mode, the heading of the message also carries：Life span (Time to Live, the abbreviation of the message “TTL”)；Before the first network node determines the node serial number of the first network node, this method Also include：The first network node receives max-forwards the node number L, the L that the first equipment is sent Integer more than or equal to N；The first network node determines the node serial number of the first network node, bag Include：The first network node determines the first network according to the TTL carried in the L and the heading The node serial number of node.
