Table 1 Underlying difference necessitating TCP re-design in stratospheric computing platform
From: TCP Stratos for stratosphere based computing platforms
S/N | Factor | Terrestrial based data center | Stratosphere based data center |
|---|---|---|---|
1 | Underlying Network | Supports segment transmission in wired networks and wireless networks. TCP has been widely used in wired networks. A re-design is deemed necessary in wireless networks. | Supports segment transmission only in the context of wireless networks. In this case, the wireless networks are in the near space region. |
2 | Coverage Consideration | Terrestrial data centre are not the primary radio transmitting entities in their host networks. The design of TCP for terrestrial data centres is loosely coupled to the coverage of the wired or wireless networks. | Stratosphere based data centres utilize high altitude platforms that have a dynamic coverage. In addition, the coverage area is tightly coupled to the concerned wireless network. |
3 | Data Volume Requiring Transmission | The Data volume to be considered is high being a data center. | The Data volume to be considered is high being a data center. |
4 | Mobility | Terrestrial data centers have limited mobility in the context of an underlying wireless networks. | Stratosphere based data centers have a high level of mobility being realized from steerable dynamic coverage high-altitude platforms. |
5 | Cooling System Dependencies | Cooling System operation is linked to the (1) power system and (2) server power consumption, and (3) network system (hosting TCP). | Cooling system operation is linked to (1) dynamic coverage, (2) wireless channel (influenced by location change to ensure continuity of free cooling), (3) power system, (4) server power consumption, and (5) network system (hosting TCP). |
6 | Role on the Internet | Established | Emerging |
7 | Suitability | Low latency for: (1) Data Access in hosting regions. Hosting regions have access to significant water resources for cooling. (2) High Latency for data access in regions that are distant to the data centre. Examples of regions in this regard are arid regions. | (1) Low latency for data access in arid regions when there is coverage. (2) Low latency for data access in regions having access to significant water resources. |
