在2月27日舉辦的MWC2018(世界行動通訊大會)中，中國移動釋出了面向5G承載的切片分組網（SPN）技術白皮書。SPN是中國移動自主創新的技術體系，分別在物理層，鏈路層和轉發控制層採用創新技術，來滿足5G業務等綜合業務傳輸網路需要。



SPN技術白皮書從需求與願景、理念與架構、關鍵技術、應用場景、總結與展望5個維度進行闡述，對SPN技術進行了全面的闡述。下一代傳輸網以5G承載為核心，兼顧家客、集客業務綜合承載，SPN是打造未來統一高效綜合業務傳輸網路的優選方案。



而SPN技術架構包括切片分組層（SPL）、切片通道層（SCL）、切片傳送層（STL）、時間/時鐘同步功能模組和管理/控制功能模組組成。SPN基於高效乙太網核心，提供低成本大頻寬承載管道，並通過多層網路技術的高效融合，實現靈活軟硬管道分片，提供從L0~L3的多層業務承載能力。同時SPN採用SDN進行集中管控，實現開放、敏捷、高效的網路新運營體系。






近日，在ITU-T SG15全會上中國移動主導推動的5G傳輸技術標準專案成功立項，該專案將SPN作為重要內容，是5G承載網標準發展的里程碑。



SPN技術白皮書的釋出將進一步確立中國移動在5G傳輸技術方面的引領地位，將進一步推動SPN技術和產業成熟。

Color the edges and diagonals of a regular polygon

Clash Royale CLAN TAG #URR8PPP up vote 5 down vote favorite 1 Here is the problem: For what $n$ is it possible to color the edges and diagonals of an $n$-side regular polygon with $dfracbinomn23$ colors, such that you use every color exactly three times and for every color the three segments (edges or diagonals) with that color form a triangle? Trivially $nequiv 0 text or 1 pmod3$. I can also prove that if the statement is true for $k$ than it is true for $3k$ as well. How to finish? Please help!

Aren't the side of a regular polygon the same as the edges? A regular $n$-sided polygon has $n$ edges. – hardmath Aug 6 at 21:20 3 $n$ ne

Relationship between determinant of matrix and determinant of adjoint?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite We are studying adjoints in class, and I was curious if there is a relationship between the determinant of matrix A, and the determinant of the adjoint of matrix A? I assume there would be a relationship because finding the adjoint requires creating a cofactor matrix and then transposing it. linear-algebra determinant adjoint-operators share | cite | improve this question asked Nov 17 '17 at 17:32 CluelessCoder 32 5 For a square matrix $A$ of order $n$, we have $A(operatornameadj A)=(operatornameadj A)A=|A|I_n$ where $I_n$ is the identity matrix of order $n$. This should tell you about the determinant of the adjoint in terms of that of $A$ (use multiplicative property and other elementary properties of determinants). – Prasun Biswas Nov 17 '17 at 17:35 1 @CluelessCoder: see here: math.stackexchange.com/questions/516127/… – Hector Blandin Nov 17 &

What is the equation of a 3D cone with generalised tilt?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite What is the equation of a 3D cone with generalized tilt? I've noticed that in most equations given to represent a cone, there is no parameter which defines the tilt of the cone in 3D space and that most of them have their point at the origin $(0,0,0)$ - I was wondering if anyone could give me a more generalized cone equation for a cone in any position in 3D space 3d share | cite | improve this question edited Jul 25 '16 at 0:05 ervx 9,425 3 13 36 asked Jul 24 '16 at 15:38 Charlene 11 2 2 Welcome to Math.SE! Could you please explain a few things to help people give an answer useful to you: 1. What do you mean by "generalized tilt"? 2. Are you asking about a right circular cone? Does the angle at the vertex matter? 3. What form of answer (implicit, parametric...?) are you looking for? 4. If this is homework, what tools do you have available, an
