mpls carrier

The meaning of carrier listening (carrier sense) is: Before sending the data, Ethernet "listens" to the cable to determine if there are other data transfers. Consider this scenario: suppose you have multiple telephones hooked up to the same phone line. If you pick up one of the phone microphones and you're ready to call, and you hear someone else talking, you have to wait until that person has finished tal

Labeled BGP (BGPV4 with label distribution capability)LDP (Label Distribution Protocol) Label Distribution ProtocolLDP operations mainly include the following four stages:(1) discovery stage(2) session establishment and maintenance(3) LSP establishment and ma

Android obtains carrier Information After receiving a new request to send the device carrier name to the server, my first response was that umeng was unable to accurately count the operator. How can I determine the specific carrier to send the request? For example: This token reflects the names of the operators that umeng collects statistics on users' mobile phon

, which is intercepted by the owner proxy and encapsulated through a IPv6-in-IPv6) tunnel to the current transfer address of the mobile node. When a mobile node receives a packet encapsulated by a IPv6-in-IPv6, it sends a binding update message. If the entry LER receives the Binding Update message from the mobile node, it initiates the LSP operation between the entry LER and the exit LER. The IP-in-IP tunneling technology of the original Mobile IP protocol has a high header overhead and heavy lo

This article is about troubleshooting MPLS ldp. Two devices establish direct-attached LDP neighbors: R2 and R3.r2 's interface Giga 2/0 and R3 interface to establish the LDP's direct-link neighbors. First, review the LDP's neighbor establishment process: LDP utility is the UDP/TCP Port 646来 discovers the neighbor's. So in the future troubleshooting, if the two sides can ping, but can not build a neighbor to check whether the port has been sealed

In the traffic engineering of MPLS TE, it is divided into the following aspects: 1, the release of information 2, the calculation and establishment of the path 3, traffic forwarding in the tunnel. So here to understand the path calculation and build, first of all to understand how SPF is working, and then see what is CSPF (constrained SPF). In order to establish the calculation of the path is a good understanding. In detail, why do you want to lea

The idea is probably to divide the SDK into operators in the OnCreate time zone.
