Introduction to lingke Xinlu Technology

The so-called IETF is an Internet Engineering Task Group. It is used to form a new working group to solve the scaling problem in the Internet routing system caused by the adoption of multi-host technology. LISP is intended to reduce the number of items registered in the route table of the core router used by Internet service providers. The following describes LISP in two aspects. 1. LISP1 and LISP can be used with Border Gateway Protocol (BGP). Border Gateway Protocol is the main communication mechanism between edge routers and core routers, our problem is to assign the IP address to the host, instead of assigning the IP address according to the structure.
This means that the core router on the service provider's network must carry routes of all specific sites. In this case, we need to try to separate the importance of the address structure from the Address Allocation program, in this way, the routing table of the Border Gateway Protocol is reduced.
2. LISP uses dynamic encapsulation to obtain a new IP Encapsulation for each packet entering the core router. This encapsulation carries information about the destination service provider's network, rather than the end user's IP address, when the package arrives at the destination service provider, the package will be deleted from the package.

3. LISP logically divides the IP address blocks that enterprises broadcast to the global Internet through their edge routers into two functions: one for identifying the systems using IP addresses, the other is used to identify where these systems are connected to the Internet, which allows LISP to aggregate location information without storing it in the core router. Ii. Route table
1. LISP is a by-product of the Internet research task group of the IETF sisters Working Group to reconsider the Internet infrastructure. The routing research group of the Internet research task group has a common objective with LISP: to reduce the size of the route table of the Border Gateway Protocol.
2. It is important that the route table of the Border Gateway Protocol grow because it will require the operator to continuously purchase a router with larger memory, thus increasing the carrier's cost. 3. The Border Gateway Protocol route table is a main table stored in the backbone router, used to determine the optimal available path between one network and another.
LISP is actually creating a network that is very different from the network we currently have. Due to the overhead produced by tunnels and the possibility of simplifying network traffic, LISP has changed its focus on timing and costs, this makes it hard to understand where the application is and how it will survive. LISP relies on tunnels, which often send too large packets, and the packets transmitted by the sender or receiver disappear without a trace.
