direction to L,m,n, then the equation of the diameter plane is
(AL+HM+GN) x+ (HL+BM+FN) y+ (GL+FM+CN) z+ (PL+QM+RN) =0
or rewritten as
(ax+hy+gz+p) l+ (hx+by+fz+q) m+ (gx+fy+cz+r) n=0
When l,m,n changes, this equation represents a planar one, by which the diameter plane of the two-time surface is formed into a plane, and the plane puts any plane through the intersection of the following planes:
Ax+hy+gz+p=0
Hx+by+fz+q=0
Gz+fy+cz+r=0

X.25 packets, to be passed through in a tunnel between GSN components. Because each user can only have one pipe at a time, the TID used to differentiate between different GTP must be distinguished from the IMSI of different users and the NSAPI distinguishing between different applications. In the existing IP network through VPN to build GPRS backbone network can ensure that the IP message from outside the network is not in the backbone of the route, increased the system's concealment and messag
GPRS provides a seamless, direct Internet connection. GPRS supports X.25 protocols and IP protocols that have far-reaching implications for the Internet. GPRS is a supplement rather than a substitute for the existing circuit-switched data Service (CSD) and short Message Service (SMS) in GSM network. GPRS can dynamically allocate wireless resources according to users ' needs, so as to realize multi-user sharing and improve frequency utilization. At the same time, the billing will be changed from
The storage structure of graphs
This article focuses on the depth-first search (DFS) and breadth-first search (BFS), so it is no longer to introduce the basic concepts of the graph too much, but to get a general idea of some of the common storage structures in the diagram below.
Adjacency Matrix
The adjacency matrix can be used both to store the graph without direction and to store the graph. In fact, the structure uses a two-dimensional array (adjacency matrix) to store the relationship betw
. The IMS IPv6 data flow flows from MS to PDN and into the IM subdomain of the mobile operator. IMS uses SIP as the control plane to control user data. User data flows to the intranet, Internet, ASP, or wasp that provide SIP applications. The most prominent issue at this stage is the difference between IETF and 3gpp/3gpp2 SIP network elements, and the interoperability between IMS and the external use of IPv4 sip devices.

In "Let WEBRTC support H264 codec" I provide a priority to use the H264 codec thinking. We can verify it on the browser side.
There are three ways to verify: In JS print SDP view Chrome's log chrome_debug.log (see Open Chrome Log) Grab bag using webrtc-internals
The first three kinds are no longer introduced, we look at the webrtc-internals.
The WEBRTC status information in the current browser can be seen in the browser address bar output chrome://webrtc-internals. Similar to the following:
